Is the small-block engine a combustion engine?
Chevrolet small-block engine
In 1992, GM created a new-generation small-block engine called the "LT1 350", not to be confused with the high-output Generation I LT-1 of the 1970s. It displaced , and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and allowing the engine to run at a higher compression than its immediate predecessors.
Oil engine
An oil engine is an internal combustion engine that is powered by the burning of fuel oil, as opposed to external combustion engines, such as steam engine. The term usually refers to low compression engines, so the diesel engine is usually not included.
