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?
The Chevy Caprice was a great car back in its day.  I had one as my first car.  It was really popular back then
