Crankshaft: The crankshaft transforms the pistons’ linear motion into rotating motion, which drives the wheels of the vehicle or propels machinery.
Camshaft: The timing of the intake and exhaust processes is ensured by the camshaft, which regulates valve opening and closing.
Cylinder Block: The engine’s structural backbone, the cylinder block, securely houses the cylinders, pistons, and crankshaft, providing robust support and stability.
Cylinders: The structures in which combustion takes place, allowing for gas expansion and energy production.
Piston: The air-fuel mixture is compressed, ignited, and turned into mechanical energy by the movement of pistons inside the cylinders. The passage of air, fuel, and exhaust gases into and out of the cylinders is regulated by valves.
Cylinder Head: This component seals the top of the cylinders and houses the combustion chamber.
Intake Manifold: Air is directed into the cylinders via the intake manifold for combustion.
