A Four-Stroke Combustion Engine (Diesel Engine): Visible Component Names and Functions This detailed, annotated model of a four-stroke diesel engine is designed for easy understanding and serves as a valuable educational resource available to everyone at no cost. Visible components include: * Cylinder Block: The main structural component that houses the cylinders where combustion takes place. * Pistons: Move up and down in the cylinder block driven by explosive forces from ignited fuel-air mixtures. * Connecting Rods: Link the pistons to the crankshaft, converting the reciprocating motion of the pistons into rotary motion of the crankshaft. * Crankshaft: Converts the up-and-down motion of the connecting rods into rotational energy that ultimately powers the vehicle. * Camshaft: Operates the valves that allow air and fuel into the cylinders and exhaust gases out of them. * Cylinder Head: Houses the valves for intake and exhaust, as well as the spark plugs in gasoline engines (not applicable to diesel engines). * Valves: Regulate airflow and fuel flow into the engine.
