I'm writing in intervals so I don't get "timed out".

Anyway......am I the only one who has not witnessed the carbureted diesel? I've never seen one out here?!! Have you? They all have some sort of injection system. I can easily visualize the fuel(oily fuel, that is) slobbing it's way from the carburetor, down the intake, up into the combustion chamber. That's a lot like running polished heads on a carbureted drag racer. The fuel starts to "wet" on the smooth chambers of the runners. There isn't any small bumps to cause turbulence and keep the fuel suspended and continue to atomize it. However......polished runners and a direct-port injected engine......MAGIC horsepower numbers!

Let me use a common example.....at least, for us in North America. General Motors 6.2 liter diesel. I know of engines that are still going today......500,000 miles strong. Yet, they are very simple. A "converted" V8 which now has a gear drive for accurate cam timing, high compression heads, glow plugs and......that's right, an injection PUMP! But, since we only have 1 cylinder on our models(most of us).....we don't need an injection pump that "times" the right cylinder and the right time to fire. We just need pressurized fuel pushed through an injector that sprays it into a fine mist. Something that "oily" fuels have a hard time doing. Put that in the place of the carburetor. This will allow it to remained lubed by the fuel like a 2 cycle. But, if we direct-port inject it......we'll have to figure a way to lube the rest of the motor.

Whenever a customer comes in with a diesel.....particularly older diesels where the injection pump is the "heart" of the engine......and they tell me that it's missing or not running properly. It's 90% of the time a problem with the injector pump and/or injectors. Not always.....but often! Nowadays, with the 24v electronic injectors and other types of systems running the newer diesels.....I don't have people with "missing" or "rough" running problems. The most I have to do with newer systems is change that damn fuel filter with all the dirty fuel they are putting in. Older systems would run "easier" on that dirty stuff.....but, eventually, it'll catch up with you in wear and tear. Newer systems need clean fuel!

Anyway, this is just my take.....if it matters. I believe that if you find an injected diesel motor. You just found a motor that'll run on anything clean and oily providing you have good compression and it isn't frozen solid with ice! Like I said.....If I had some R&D money and a lot more time......I garuantee I'd be trying to fabricate some sort of injected diesel model. Then, after that........TURBO CHARGER!!!!!!!! Good bye Nitro methane FOREVER! That is......until they make battery for electrics that last all day......
