I've noted in various information circles that there is a good possibility that Honda will introduce their i-CTDi diesel engine to North America in the 8th generation Accord. It will be most interesting to see how this engine performs compared to the diesels we've come to know in the past, which were noisy and comparatively unsmooth.

My parents used to have a 1980 Mercedes 300D diesel; arguably one of the most durable cars ever built (with tens of thousands still on the road today). That car had the usual diesel shakes and engine clatter, and of course smelled like a diesel, but I recall it performed reasonably well over the 10 years we owned it. Was a good car.

If pollution controls can be perfected to consistently deliver California standard emission ratings in curbing soot and NO2, in conjunction with low sulfur fuel, the rise of diesel could significantly reduce the carbon problems we continue to deal with in regards to our transportation needs. Diesel won't necessary reduce our dependence on oil, that said-- But it at least might prove more economically practical for consumers in yielding a lower cost of operation, in addition to the aforementioned improvement in emissions.

Overall, I'm excited about the possibility of diesel locomotion in the Accord. And, contrary to what many may believe, the i-CTDi isn't slow, either!

And.... Discuss! :thumbsup:


EDIT: Check it out: http://world.honda.com/HDTV/news/2003-4030226_1a/

I look forward to it myself. Honda said 2009 would be the USA launch date or possibly late '08.

isnt it just bliiiiiiss....when a diesel goes like thiiiiiiiiisssss?

Additional note regarding diesel myths:

There is a widely held belief that the use of diesel fuel will end up reducing the amount of crude oil consumed, based, assumingly, on the fact that diesel vehicles deliver better mileage than their gasoline driven counterparts. This is incorrect, unfortunately.

The reason for that can be found in basic scientific principle: Conservation of energy.

Consider that, by and large, all crude oil contains a set amount of energy per given volume. Second, consider that diesel fuel contains more energy per unit of volume than does an equal volume of gasoline. Given that crude oil contains a set amount of energy, it follows that diesel fuel contains more crude oil than gasoline; the corollary being it takes more crude oil to produce an equal volume of diesel than it does gasoline.

Granted, oil refining is a singular process, meaning you heat it, it evaporates, and various weights of fuel condense out in various positions along the cooling tower, so you end up with all types of fuel simultaneously (including diesel and gasoline)-- But either way, increase in demand for diesel also increases demand for crude oil, because you’ll have to cook more crude oil to yield the diesel that’s in demand-- More so than you’d have to to satisfy gasoline demand.

So it’s likely that the increase in diesel engine efficiency will be offset by the fact that you have to cook more crude oil to satisfy diesel fuel demand, thus negating any crude oil consumption improvements. Which leads to a whole rat's nest of other problems, like dependence on foreign oil, consequential war profiteering, etc..

There’s your additional diesel info for the day!

I had considered a diesel pick up truck as my personal transportation a few years ago and decided against it.

I had planned to run it on home heating oil, which is the same as diesel ( at least locally) but does not have the dye in it to identify it as a taxed motor fuel. I figured I would install an extra fuel oil tank in my garage and run a farm style dispensing pump.

Would really love to own a Diesel Accord. Come on Honda US and Canada bring it here.

Fuel prices rising, we need more economic vehicles, plus it gives consumers and alternative from the VW and Mercedes diesel offerings.

Hi Geologic.

I am not sure your following comment is entirely correct?

>>>Consider that, by and large, all crude oil contains a set amount of energy per given volume. Second, consider that diesel fuel contains more energy per unit of volume than does an equal volume of gasoline. Given that crude oil contains a set amount of energy, it follows that diesel fuel contains more crude oil than gasoline; the corollary being it takes more crude oil to produce an equal volume of diesel than it does gasoline.<<<

I was taught that diesel oil takes a lot LESS refining than petrol, and you lose more energy producing petrol, than you lose producing diesel, if that's true, then you would get more diesel from a given amount of raw crude oil, not less, and... Diesel is cheaper to produce? Is that not correct? :dunno:

Anyone have more/better information on this?

I personally would have an additional home heating oil tank with one of these pumps screwed right into it. I would plumb both tanks together at their bottom with the largest diameter pipe that fits, and join the vent pipe at the top similarly, so the delivery truck fills both at one spot. I would recommend a valve between them so you don't leave yourself without any heating oil.

It wouldn't take much creativity to pipe the discharge from the pump to a convenient location to fuel your vehicle outside, with a switch near the dispensing nozzle and hose. I recomend some sort of light that goes on when the pump is on if you can't hear it run.

Refining crude oil is a basic matter of heating it until it evaporates. As it rises in the refining tower the oil cools and then condenses at various levels, each level being a different type of fuel, from heaviest (like petroleum jelly, lubricating oil, kerosene, and so on) to lightest (butane, etc.). You don't start a refining run and end up with only, say, diesel fuel-- You end up with ALL the types of fuel we know-- Because it's all done in one process.

Example:

Refinery starts a refining run for 5 hours.

X amount of diesel is produced.
X amount of gasoline is produced.
X amount of white gas is produced.
And dozens of other types of fuels are also produced-- As noted, all at the same time.

There are two processes that could in fact add to the cost of gasoline production, as far as I know. One is all the additives that must be introduced to the fuel to stabilize it; such as increasing octane ratings to combat pre-detonation. The other is chemical processing of heavier fuels to yield additional gasoline. As in, after running a standard refining process using heat to evaporate crude oil, as noted above, the refinery can chemically process heavier fuels such as diesel to yield yet more gasoline; a lighter fuel. This increases the amount of gasoline you can get from a given amount of crude oil. These processes add to the cost of production.

I’m mostly certain that refineries can’t go the other way around, though-- At least not cost effectively. That is, crunching lighter fuels together to yield diesel. Given that, the only way you get diesel is from age old crude oil boiling/condensation. So, maybe yes, diesel is cheaper to produce overall. But if you increase demand for diesel then they won't use it anymore to produce additional gasoline, so the process of producing each type of fuel will again flow back to basic boiling, thus more equalizing their production costs.

That said, recent regulations now require additional refining to remove excess sulfur content from diesel fuel, so it too must undergo additional, cost increasing processing prior to market.

The bottom line is I think the cost of production will always basically even out for every type of fuel refined, no matter which type happens to be in highest demand.

But my original point remains: Increased use of diesel fuel won’t reduce the amount of crude oil we consume. And, thinking about it further, because crude demand won’t lower, I believe we won’t see any cost savings, either-- Diesel will end up costing about as much as gasoline does, now.

I believe the benefits of improved emission performance, along with the diesel engine’s far greater flexibility in terms of the type of fuel it can burn (bio fuels, old cooking oil, etc.) still make it a good way to go. So I remain excited about the possibility of Honda bringing their i-CTDi engine to us…

Anyway, hopefully I don’t drag things too off topic! This is a very interesting subject to me, though!

Cheers, all!

A diesel would be a strong pull for me towards another Accord. I'm hoping its on the market when I'm shopping December 2008.

Hi Geologic, and thanks for all the additional information.

Living in a Country (UK) that has lots of diesel cars around, it is obvious to me that the reason people like me buy diesels is because they go so far on a gallon of fuel :yes:

Owning two closely identical size cars and engines, one diesel, one petrol, (both automatics) my diesel costs me about half that of my Accord to run based on fuel costs. The 1.9D engine averages 46 mpg, best ever being 55mpg over 350 miles (90% motorway).. :thmsup:

The 2.0i petrol engine averages 23 mpg, best ever 28.5 over 370 miles (90% motorway).

Diesel and petrol are approx the same price here, but obviously the diesel is far cheaper to run simply because it goes twice as far per gallon of fuel. :)

Newish diesels WONT run on bio fuel, old engine oil, or cooking oil, without making costly alterations to the engines, mainly because the ECU's army of sensors get diff reading from them and promptly put the car in limp mode, or shut it down altogether.. Duhhhhhh :thumbsdow

My ZX is 13 years old, so it has a Bosch mechanical fuel pump capable of pumping treacle if needed.. lol.. :D ..It has no ECU to shut it down, so it just does what its supposed to do, = it runs. :biggrin: But.. It still has to comply with the modern emission tests that all UK cars take every year, and it passes with no problems at all.. :)

Re cooking oil, my ZX performs better on it, but gets about 10% less MPG. Good financially as cooking oil is 60% cheaper than diesel fuel, but 10% less ECO friendly.. :( My choice of fuel is a 50-50 mix diesel/cooking oil at the moment. and most of my motoring is done in the diesel, I just use the Accord for fun outings and holidays, because it's a nice car to drive, and has lots of nice toys like a/c, cruise, sport mode, etc etc. :D
.

Can anybody tell me if the new high tech Diesels require a catalytic converter? That would be a plus if they don't. Replacing the converter(s) on a petrol car can be very expensive when out of warranty. :(

Hi Copacetic.

I don't actually know anyone who owns one of the Honda diesels, and neither do anyone else I have asked, they seem to be extremely rare here, why, I don't know.. :dunno:

My tame mechanic tells me that 99% of all diesels made since approx 1995 have cats fitted.. :( so the answer is almost certainly yes, it will have a cat... :( ..That's an educated surmise, as he hasn't seen one yet either!

As it's not a "normal" diesel engine I can't get much information on it. :dunno:

As I understand it, the new Honda diesel is a low/lower compression engine, running at higher revs than a "normal" diesel engine, the idea being, it is a sort of cross between a petrol and a diesel design.. How that works in practice is an unknown to me, I fear it may well fall between the two, and end up using more fuel than the ave diesel, but less than a petrol engine?? :dunno:

We can only wait and see.. ermm.. and hope? lol... :D
.

Greets again, all!

Good info regarding European diesel pricing, James.uk. Interesting to learn, and cool to hear about how things work across the Atlantic! I believe in many respects it would be well for us in the U.S. to adopt similar fuel policies.

I've often wondered what the differences were between Europe and the United States in terms of why Europe far more readily adopted diesel than we did here in North America. Europe had the same "clunky" diesels we had in the U.S. in the 70's and 80's, yet they were able to overcome this negative perception while, it seems, the U.S. never did. I suppose some of it might have also had to do with government energy policy; the United States being somewhat of a rogue, globally speaking.

Regarding catalytic converters in the new Honda diesel-- Yes, the i-CTDi indeed has a rather complex catalytic converter. Its two primary purposes are to reduce soot emissions, and secondly to reduce NO2 emissions. Honda apparently opted for this type of system vs. the urea exhaust injection method in development from the likes of VW and Mercedes (which requires a tank of urea that has to be periodically refilled-- Less convenient that Honda's method, I feel. And yes-- Urea is a component of… Piss! No joke! Nasty, eh? I guess the ghetto method of Mercedes diesel emission cleanup would be to have a guy standing over the exhaust pipe taking a leak through the smoke-- :lmao:).

And that's another very good point from James.uk-- Contemporary sensor/computer control systems likely are quite sensitive to fuel type. Add to that, the aforementioned catalytic converter system, finely tuned to function with conventional low-sulfur diesel fuel, would probably be ill effected by alternate fuels. D'oh! :censored:

Hopefully modifications will be safely possible though; perhaps some time in the future...

Can anybody tell me if the new high tech Diesels require a catalytic converter? That would be a plus if they don't. Replacing the converter(s) on a petrol car can be very expensive when out of warranty. :(

They have more than just a CAT now. They've got a catalytic converter and a DPF (diesel particulate filter) all mounted on the exhaust along w/ your muffler and resonators. The particulate filter traps soot from escaping into the atmosphere. It has its own cycle where it heats up to burn off all the soot. Both the Cat and DPF will have sensors on them so good luck removing them. They say the DPF's will last around 100k before servicing. I highly doubt it.

Hi Geologic.

>>>I've often wondered what the differences were between Europe and the United States in terms of why Europe far more readily adopted diesel than we did here in North America.<<<

I think the answer to that is the cost of fuel, petrol and diesel are about 97p a litre in the UK, I think that's about 7$ a U.S. gallon? So diesels are very economic when compared to a petrol engine. And, broadly speaking, they are also far more robust and reliable.. :)

Modern diesels don't have much diesel "clank" really.. But mine does. :D I love it, it sounds like a lil lorry :D But the car has good sound proofing so you can't really hear it with the windows closed. Above 1,500 rpm the clank disapears altogether and it sounds exactly like any other car.. :rolleyes:
.

Thanks all for the very informative replies. The urea process definitely sounds like a hassle. Lets hope that Honda can make the i-CTDi pollution controls durable so you don't have to gamble on a high rebuild cost when the miles/years start to rack up. Guess we will have to just wait and see.........

A diesel will last a very long time. The shortfall to all of this is diesel motors were never intended to have all the emission stuff associated w/ them. This I feel puts a damper on the whole "diesel lasting forever" saying.

But, technology has come around 10 fold for diesels in the last few years, too. High (23k) psi fuel systems, injectors that atomize and put gas injectors to shame, ECM alone is a work of art. These diesel's today can be animals w/ just a programmer plugged into the OBDII port, pick what level of horsepower you want, and 15 minutes later your terrorizing the streets and getting better mileage than stock to boot. :thmsup:

Diesel "last a long time" because they are "heavy duty" construction as compared to a gasoline engine.

At one time the Oldsmobile 350 cubic inch diesel engine block was preferred as a "racing" gasoline engine block because of it's structural enhancements

yep yep, diesels are high compression engines, approx double that of a normal petrol engine, so they have to be very robust indeed to take all the additional loads, stronger explosions = more heat, plus longer strokes, bigger crank throws, much more output torque etc etc..

But:- the more bits/refinements they add on, the less reliable the engine will become... Personaly, in this case, I think simple is best.. Dohhh heh heh... :banana:
.

I've worked with industrial diesels for years. They can run "forever" if you maintain them.

One place I worked had Detroit Diesels that dated to around WW2, and still ran. They sweated oil and were messy, but still did the job.

Detroit Diesels are interesting because they are two stroke diesel engines

Honda's version runs a CR of 16.7:1, and autos are commonly at 10:1 today.

My family will never own a diesel for two reasons. We hate the smell or the exaust & raw fuel, and the ultra complex emissions sytems to meet EPA regs.

Wait until we understand more about particulate filters. There will be a lot of discussion about the need to clean these out in the furture. Estimates today range fron every 50k up to 150k, and some say it will be similar to an oil change. Who wants to find out first!

Why does everyone assume that diesels smell?? :dunno:

The only time I smell the fuel is at the pumps during a fill-up, and that applies to both cars, not just the diesel.

We have been running diesels worldwide for many generations now, that problem was discussed many times and resolved long ago. Nowadays Diesels have to pass very strict emission tests here every year in order to be allowed to remain on the road. :)

People have preconceived notions or have had past experiences with old diesels.

I doubt my parents would ever get a diesel. Back in the early to mid seventies they test drove a diesel Mercedes Benz. They didn't buy it because the diesel fumes made my mom sick. Although I'd assume that things like that have greatly improved over the last 30+ years.

I'm guessing they were looking at the diesel Benz because diesel was cheaper and got better mileage, especially since that was during the whole energy/fuel crisis thing. Don't quote me on that, though. I need to check my facts, and my parents are currently in eastern Washington, so I'll have to wait until they get home.

Hi Amanda. I remember some old petrol cars that got full of fumes and made everyone sick! :D heh heh..

As you rightly say, that was a long long time ago. Todays diesels are, to all intents and purposes, the same as a petrol car to travel in.

If you have been to the UK then you have been in a diesel car, as 99% of all taxis here are diesel, and have been for many years .. :yes:

Turbo diesels are the norm now, but I prefer the old non turbo simply because reliability is far more important to me than speed, and turbos are just more potential problems waiting in the wings to go wrong! :paranoid:

16.7 to 1 compression ratio (the new Honda engine) is low compression for a diesel, but too high for a petrol engine as the petrol would pre-ignite.. I think petrol self ignites at around 12 to one ish due to the heat created. Wheras diesel compression ratios are normally about 20 to one.

One item that does seem to to have slipped through the net, are all the old diesel generators? most builders use them for on-site elec power. They are very noisy, usually stink, smoke, and give off noxious fumes all day long but no one seems to care? and wordwide, there must be zillions of them! lots of them actually run inside of the buildings where the workers are all day.. crazy huh.. :dunno:
.

on the US navy aircraft carriers, we have emergency diesel generators on board.... i think 3 of them.... :yes:

In the USA there aren't very many "old generators" because the components to keep the electrical end become obsolete and hard to find, the wiring and electronics become unreliable, and the generator techs sell people new generators.:D

Diesel and propane or natural gas are the preferred fuels for generators. Gasoline is a pain in the neck and only suitable for small units.

On the other hand, the engines usually have low hours and make excellent replacements for older trucks and off road equipment needing to freshen up.

No reason for a diesel; U.S. is (still) a modern society with gasoline refining capability. Diesel takes a huge amount of maintenance compared to modern gas engines, ie., oil changes out the wazoo. Used to be gas engines needed lots of maintenance so the edge was with diesel in overall costs. Gas engines have now gotten past that.

Diesel mechanicals also are very expensive to buy & fix, the engines are heavy making the car nose-heavy with lifeless handling, soot everywhere (yes, even invisible particles can help clog up the air, filters, your lungs, your neighbors...), good torque off the line then nada performance, high torque meaning heavier duty transmissions (meaning even more weight), the list goes on and on...

And, THERE IS A FINITE SUPPLY OF DIESEL, because as much cracking as possible is done in the refinery to produce more gasiline, which is usually worth more money. So recently you got the odd effect of diesel costing more than premium, as the supply dried up and the 18-wheelers simply had to have it.

Senseless economics just like hybrids. The only reason supporting diesel is high load (towing) applications where you need the engine to run 300,000+ miles.

Hi Cudawuda..

>>>Diesel takes a huge amount of maintenance compared to modern gas engines, ie., oil changes out the wazoo. <<<

Most diesels run better with 5K oil and filter changes.. Other than that, I don't touch it? so where's the "high maintenance" you mention?? :dunno:

>>>Diesel mechanicals also are very expensive to buy & fix<<<

Nothing goes wrong with them, so how can they be expensive? I have had a diesel for 6 years now, 35k miles ish, the car has never broken down, and never failed to start? My friends diesel has never let him down in 10 years! the diesel is a very simple, robust engine, they DONT break down! :dunno:

>>>good torque off the line then nada performance,<<<

The diesel turbo citroen ZX Volcane will leave a Golf GTI (and my Accord) for dead! todays t/d's are very very fast! !:yes:


>>>the engines are heavy making the car nose-heavy with lifeless handling<<<

The engines are heavy, but all front engined cars are front heavy? they build the suspension to offset that. Lifeless handling? lol.. Only on a lorry or a tall 4x4! :D My ZX corners extremely well due to its passive rear wheel steering. :thmsup:

>>>THERE IS A FINITE SUPPLY OF DIESEL, because as much cracking as possible is done in the refinery to produce more gasiline<<<

If you have more diesels, then you don't need so much petrol? :dunno:

As for profit, we pay the same price for both products here and in most of the EU..

>>>Senseless economics just like hybrids.<<<

Heh heh I like that one... Now that i can legally run my diesel on veg or cooking oils @ 33p a litre, my diesel costs approx £3 per 100 miles.. The Accord costs me approx £20 per 100 miles .. I call that very GOOD diesel economics! excellant in fact!! :yes:

I love diesel cars, and owning one of each, I am in a good position to compare and judge! :thmsup:

I assume from your comments that you owned a diesel car at some time, what model - age was it??
.

In the Portland area used TDI's command some strong values. The people I know with TDI's like their cars. Non TDI VW's seem to get much more mixed opinions.

I think people who don't have modern experience with diesels tend to have a negative impression.

Diesels require very little maintenance compared to gas engines. We our current diesel (2002 Cat C7) has 15k oil chances, and really no service needed besides one valve adjustment. No timing belts or chains...all gears, no glow plugs, no spark plugs,.. nothing. It runs forever and is a great engine.

If I'm wrong I'll admit it, but I don't see any miscalculation so far. My experience was with a 1981 (?) Diesel Rabbit. Replacing those diesel injectors is expensive. They do have parts, expensive parts, that break.

Turbos? Active rear suspension? Not happening in an Accord and maintain a reasonable price point. They only thing Honda has going for it, regarding diesels, is not needing urea supplements to keep the emissions down.


Let's just keep all those diesels in the EU.


:screwy:

Hi Cudawuda.

I dont think you were wrong about the 1981 Rabbit, it was probably very true of diesels then. But that was over 25 years ago.. diesels are a whole new ball game now. :) If they were not, I wouldn't have bought one.. I like breathing clean air as well! :D

>>>Replacing those diesel injectors is expensive<<<

In the UK you can buy new injectors pretty cheaply now, less than £100 ($200) for a set of 4 I think, they even recondition them if you cant afford a new set. I have never needed to replace any thou.. But they should and do last for up to 200K miles. That works out about the same as new plugs on most cars over the same distance.. erm... but not many petrol engines last that long! :paranoid:..

>>>Turbos? Active rear suspension?<<<

Turbos are the same no matter what type of engine they are fitted too, petrol or diesel. But the diesel turbo is normally a bit more robust and slower revving. As far as I know, only Peugeot and Citroen made cars with passive rear wheel steering, and its standard no matter what engine is fitted petrol or diesel. In fact a petrol ZX won the Dacca rally a couple of times in the past. So it's a fairly reliable car even without a diesel engine!! heh heh .. :)

>>>They only thing Honda has going for it, regarding diesels, is not needing urea supplements to keep the emissions down.<<<

I have never seen or heard of anyone here having that system fitted in their diesel car? I don't think it ever actually went into production. :dunno: All diesels here have to pass very strict emission tests every year, if they fail the test then they can no longer be taxed or driven legally on our roads. And the test centre computers are on a National grid and sent straight to the vehicle taxation deptment. So if your car fails, they know! :paranoid:. They are extremely strict about emmisions here.. :yes: :D .. Petrol cars are also emission tested annually. :)

>>>Let's just keep all those diesels in the EU.<<<

Good idea, I don't object to that at all! .. I love mine! :naughty: :lmao:
.

One way to help pass an emission test is to introduce more air into the exhaust system. This dilutes the exhaust. The way it was done was to open a v shaped punch into the pipe kind of like a simple whistle. The flow of the exhaust gasses passing the hole drew fresh air into the tail pipe.

Every little bit helps, sometimes:yes:

Hi FnW.

Nah that won't work here, the whole car is examined for any defects including the exhuast system.. :naughty:

But.. wouldn't that allow fumes to escape under the car making a bad smell, a loud noise, and gassing the poor driver!! lol..

Here in the colonies it appears that all the oil burners (cars) will have it except Honda. I assume the new diesel emission standards here are even more stringent than the UK.

It works kind of like a damper on a furnace exhaust pipe.



The "air" passing through the pipe starts at the tapered end of the punch, and as it passes the deep side with the hole, it pulls fresh air in along with the flow. The interior air (exhaust gas) doesn't escape.

The one I saw had it's punch facing up over the rear drive differential and was not visible by casual observation.

does it tow? lol

The new Duramax has the same type of fins on the exhaust pipe. They mainly are used to cool the exhaust temperatures as they get very hot after regeneration in the particulate filter. During regen is when you could possibly set something on fire with the hot gasses, so these were installed on the exhaust systems.
