I love my Chevy Truck.  Its got a great Duramax engine!
What is a duramax engine?
It is a GM V8 diesel engine built for their trucks
What makes it unique?
Diesel engines work by compressing only the air which increases the temperature enough that the fuel ignites spontaneously.
So how are they different from regular engines that dont use diesel?
An internal combustion engine is where the combustion of a fuel occurs with air in a chamber that is part of the fluid flow circyuit
that awesome, i didn't know that, what do you like about chevy's beside the engine?
Chevrolet Caprice
The Chevrolet Caprice is a full-sized automobile produced by Chevrolet in North America for the 1965 to 1996 model years. Full-size Chevrolet sales peaked in 1965 with over a million sold. It was the most popular American car in the sixties and early seventies, which, during its lifetime, included the Biscayne, Bel Air, and Impala.
Introduced in mid-1965 as a luxury trim package for the Impala four-door hardtop, Chevrolet offered a full line of Caprice models for the 1966 and subsequent
plug to ignite an air-fuel mixture. 
Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogeneous air-fuel mixture. The process of mixing air and fuel happens almost entirely during combustion, the oxygen diffuses into the flame, which means that the diesel engine
