As for whether I understand the refining of aliphatic hydrocarbons or not, gasoline is a mixture of C7H16 through C11H24, all which boil at temperatures lower than water which is why they evaporate so readily. Kerosene, diesel and other fuel oils are in the C12Hn to C17Hn range. The denser oils and solid waxes (C18Hn through C80Hn) are typically cracked (a refinement process used to literally split apart heavy hydrocarbons into lighter ones) and later reformed using a process called alkylation but diesel isn't cracked as it's a desirable commodity.

I started this thread to discuss the idea of a diesel engine for the H3. The H1 had diesel engines since the beginning and, from what I've read, many people would welcome a diesel option in the H2. Others expressed their opinions both yea and nay. From your posts, I'm not sure if your problem is with me or diesels or both. If I did something to upset you, it wasn't intentional (especially since I have no idea what your beef is) but if you're hoping to impress or intimidate me, you've failed on both counts.

I drive a Duramax. I'd LOVE to have that engine and transmission in an H2, and a 6 cylinder version in the H3. Better mileage BY FAR better mileage. Off road, diesel's the ticket, it's torque off idle is a perfect match for the conditions.

Catalytic converters have been on diesels for a while now, they're not clogging up any more than any other vehicle. New for '07 WILL be particulate filters. They will not clog up either. They're designed to go into a self clearing burn off mode to keep it clear. They won't last forever though and will have a projected lifespan of about 100k miles.

People that don't like diesels haven't owned one. There's not a gas engine out there that will pull, or give the mileage of any of the big three diesel pickup truck engines. My Dmax is no more noisey than some chucklehead's aftermarket exhausted anything. It doesn't make smoke.

To keep this discussion real: The H2 is going bye-bye unless they put a diesel in it to bring the mileage up. It takes torque to maintain the thing at freeway speeds, at a low rpm, and get good mileage. The H3 could benefit from ANY engine upgrade. I'm imagining that six cylinder Dmax with a sweet six speed behind it and getting in the mid 20s on mileage. Ohhhhhh yeah!

That's a dream at best.

Dreams don't become reality in the auto world without customer demand. Hell, they built the SSR and Prowler didn't they? How far fetched were THOSE things?

Agreed, dreams are worth striving for in the automotive world. But from a business standpoint, SSR's and Prowlers are marginal at best both technically and economically.

I'm holding out hope for a nice turbo diesel. I personally agree with the original poster, and feel a nice modern turbo diesel would be an excellent engine choice for the H3, especially if offered with a manual transmission. Clean, considerably better fuel efficiency, excellent off idle torque. I doubt that GM will be able to have the vision to see the possibilities though. They are only doing it in Europe because the truck would be doomed without it there. Europeans love their diesels, and for good reason.
