ABSTRACT
The transfer of power from its source of generation to its final destination where useful work occurs is the subject of much study and engineering development. In the case of internal combustion engines, liquid fuel is combusted by compression ignition (diesel) or spark ignition (gasoline). The gas expansion pressure within the combustion chamber drives a piston, which, in turn, translates reciprocal motion into rotary motion via a connecting rod that is attached to a crankshaft. Once the crankshaft is set in motion, pulleys, chains, clutches, and gears continue the chain of energy transfer to accomplish the ultimate purpose of the engine, be it transportation, pumping, electricity generation, or the like.
