i was junt wondering what all is needed. i assume that it have to be retuned and need differant plugs. but what else? differant injectors? dizzy? fuel pump..ect? just had the idea and thaught it would nice to have somthing differant. any ups and dows that you can think of would be nice as well.

 

I don't know about that.....

You should read up on ICE's. They are completely different motors. One is a spark-ignition engine, another is a compression-ignition engine. I can get into some detail, but I suggest some Googling first.

 

i have an idea of how they work, but i assume that it is possible because both have the same internal components. valves, pistons, rods...ect

Well, yes....but no.

The technical name of a diesel engine is a compression ignition engine. I'm sure you knew that already, but by the name itself, it tells you that the combustion is achieved through compression alone, rather than a spark.

The compression inside a diesel engine is much higher than a regular spark ignition engine. I don't have my ICE book here with me, and I forgot the details. Note that I didn't take the ICE engineering class, I just read the book for fun.

At near the top of the piston stroke, the fuel is introduced into the chamber, and by the high comp alone, it combusts. Someone correct me if I'm wrong, but the temperatures and pressures in there are just like detonation pressures/temps in a regular spark-ignition motor. We all know how bad that is. Thus, the timing of a diesel engine is also crazy high. A diesel engine is VERY strong in that respect.

However since it must be so strong, it's large and heavy. Smaller ones, don't make that much power, thus they pretty much always have a turbo or something.

Blah....I can keep going....but you get the point. Very different.

 

how high compression are we talking? i have some ctr pistons?

Heehee.....like 25:1 or more.

 

damn! sounds like it would be hard to get compression that high without breaking a sleeve.

Exactly. A diesel engine combusts through compression alone. Think about you trying to make a cup of gasoline explode just by compressing it. Takes a lot of damn pressure, right? Keep in mind, you're not allowed to use a spark or any ignition device.

The point I think you're failing to grasp here, and which shamoo is being very polite and informative while trying to convey to you, is that you will not be able to convert your engine to diesel. Not with CTR pistons, nor with new spark plugs, injectors, etc.

Can it be done? Sure, like many other things, with enough money it isn't outside the realm of possibility, though the end result would probably still not be up to par with even a poorly designed factory diesel engine. You'd likely find it less difficult and expensive fitting the diesel engine of another manufacturer into your car. Of course, this is no simple matter either, and if you're interested in diesel power (as many people, including myself, are) you might simply want to look into purchasing another vehicle that is already available with a nice diesel power plant.

 

i understood that difficulties as soon as he said 25:1. i think that with proper tuning it would be on par with other diesel engines. although still not worth it.

that is an interesting idea about dropping in a diesel engine. do you know of anyone who has done this?

 

Being curious and asking questions does not make someone a moron. I would much rather see a tech-related discussion, however implausible the original idea might be, than read through many of the other threads that are becoming more and more common here.

Freakasis, I'm not familiar with anyone who has performed a diesel swap. There is a (very) small chance that you might find some information in the Hybrid forum, but you may also want to try contacting some shops that specialize in custom mounts and swaps, and discussing your idea with them. As far as engine choices, the VW TDI comes to mind as the most viable due to its size, prevalence, and after-market support. It's an excellent and well-proven power plant. Honda has recently released a diesel in Europe, so that might also be an option you could investigate.

 

thanks for backing me, and for the imput. i believe the deisel engine that they sell is actually a gm motor. they traded for the vtec motor that is in the 05 saturns. but the gti motor does sound nice. hm...i may just have to look into that. although when you swap in motors from differant makes you will get lotsa anoying problems...like the spedo, and such...anyway thanx

hey, its an idea. people like you suck.

"some people"?? like the people who started honda? like the people who invented...umm lets see...EVERYTHING!!!

you couldnt come up with anything original if you tried...i think yer username is a testament to that.

You people are hopeless. The orginal idea was to "Convert" an existing Honda motor to run on diesel. That idea is totally implausable and makes no sense whatsoever, or would it even be possible. To save face your disscussion changed to swapping in an already diesel motor. I can't even bring myself to fathom what goes on in that head of yours. Furthermore, people who have something invented have their product marketed for a reason, that being that it was a good idea not like your lame *** hypothetical situations that will never get anywhere beyond your thoughts. Why don't you figure out how to make my motor run off some balsamic vinegar or some ****.

The idea of converting a gasoline engine to diesel has been around far before freakasis inquired about it. In fact, General Motors experimented with the concept years ago, but those were only automotive engineers working for one of the largest automobile manufacturers in the world...

The discussion shifted when freakasis learned the great difficulties involved in undertaking such a conversion. Learning and sharing information is, after all, what Honda-Tech is for, though it seems that concept is becoming somewhat lost as of late.

It doesn't seem to me he did it to save face. It seems to me he was simply honestly ignorant of the Diesel cycle and how different it was from the Otto cycle, and how different all the parts had to be.

 

How are you any better than me dude? Your sitting here calling this guy ignorant! WTF is that about? There's a big difference between being uneducated on a a topic, and calling someone flat out ignorant. I did nothing more that question his sexuality by calling him "a pile of sticks," and you sit here insult this poor saps intelligence and have the nerve to lower my rating points. With all due respect bud, that is totally proposterous.

 

Wow this went from a funny thread, to an education thread, to a name calling thread.


Anyways. I would be willing to bet that honda makes a diesel engine that is for sale in europe. When i was in europe last year a LOT of the cars are diesel. While I have done no foraml reasearch I would say honda has a diesel engine. If you are really interested in doing this swap I would start to look for what engines are speced on the UKDM cars.

Good Luck

 

The term "ignorant" is not always used as a negative term. George was simply saying how the original poster didn't know the complexities of converting the engines because he doesn't know the exact details of how a compression-ignition engine works. Nothing wrong with that. He wasn't insulting his intelligence. Mr. Knighton isn't the type to do that anyway. That's why we posted a little and tried to educate....isn't that what HT is for?

Calling him names (in a negative way) gets nowhere. He wanted to know how to convert the engine, and he found out that it is very difficult. You just called him dumb for even thinking about it. Why? Cmon now. We're all here to learn. I didn't know MANY things when I first joined. Now I do, and I'm trying to help out other new users.

[QUOTE=Racermech]Wow this went from a funny thread, to an education thread, to a name calling thread.

 

I must apologize for anything i said that was taken the wrong way, its just that most of the time people won't even listen to you when you are trying to help them, and i guess i have quite the short fuse.lol. that and i haven't slept much this weekend. Damn College girls. lol.

 

i had an idea on how they worked but i didnt realize the compression was that high. right after i posted i went to howstuffworks.com and looked it up.

i wonder if they put any diesel engines in the civics over there? if they do i can only hope that it would be a bolt up. but prolly not.

i know its hard to figure out what people mean by what they say. since you cant hear the tone of their voice.

for all of those who put down ideas:
F**k off.

for all of those who helped:
thanx for all the input

 

This man is kidding, and it is ridiculous that you went along with his joke. The part that ruined it was when he said the CTR pistons would probably raise the compression enough. Shame on you all.
Anyway, on the subject of diesel power. I currently drive a 2001 VW golf TDI, while I am building my DA. Now, by all means this is a nice car... but not BECAUSE it is diesel, more like in SPITE of it being diesel. Horsepower is something diesel engines dont know, the diesel trucks running at the track are large displacement, and running so much boost that the smoke billowing out of the pipes (or smokestacks) pretty much blocks your vision of the race. A diesel engine, small enough to fit in a car, has plenty of torque, and is great for put putting around.. But a stock LS will tear most any of them a new *******.
