internal combustion engine
Key to diagramAn in-line, four cylinder gasoline engine is the most common internal combustion engine used in cars. Air is sucked through a filter (1) into the carburetor (2), where it mixes with the gasoline. This mixture then enters the cylinders through the dual inlet valves (3) on each cylinder (4). The spark plug (5) then ignites the mixture forcing the piston rapidly down. The burnt gases are expelled through the outlet valves (6). The reciprocating motion of the pistons is converted into rotation by the crankshaft (7). The crankshaft also turns the timing belt (8) that controls the opening of the valves, through the cams (9) located on the camshaft (10), and also the firing of the spark plugs.
