Engine performance systems (Part three)

Engine performance systems (Part three)

Engine control systems : As manufacturers come closer to achieving complete combustion, engines are able to produce more power, use less fuel, and emit fewer pollutants. This has been made possible by technological advances, primarily electronics. The computer is an engine control system that functions like other computers. It receives inputs, processes information, and commands an […]

Crankshaft

Crankshaft

The crank shaft ( see photo at the end of the article) converts the up and down motion of the pistons to rotary motion. The polished bearing surfaces are called journals. The journals that support the crank shaft as it turns are called main bearing journals. Rod bearing journals transfer up and down motion between […]
