Engine parts on heavy equipment are essential to ensure optimal performance. Some of the main parts of the engine include the cylinder block, which serves as the combustion chamber; the piston, which converts gas pressure into motion; the valves, which regulate the flow of gas and the air-fuel mixture; the crankshaft, which converts the linear motion of the piston into rotational motion; and the cooling system, which keeps the engine temperature stable. In addition, the oil filter and fuel system are also important to maintain engine performance and prevent damage.
