Parts of an Engine of a Car

Engine Block

The engine block is the main structural component of the engine. It contains the cylinders, which are the chambers in which the pistons move up and down to generate power.

Cylinder Head

The cylinder head is located at the top of the engine block and covers the cylinders. It contains the valves that control the flow of air and exhaust gases in and out of the cylinders.

Pistons

The pistons are cylindrical-shaped components that move up and down inside the cylinders. They are connected to the crankshaft by connecting rods.

Connecting Rods

The connecting rods connect the pistons to the crankshaft. They convert the up-and-down motion of the pistons into rotational motion of the crankshaft.

Crankshaft

The crankshaft is a rotating shaft that is located at the bottom of the engine block. It converts the reciprocating motion of the pistons into rotational motion.

Camshaft

The camshaft is a shaft that is located at the top of the engine block. It controls the opening and closing of the valves in the cylinder head.

Timing Belt or Chain

The timing belt or chain connects the crankshaft to the camshaft. It ensures that the valves open and close at the correct times.

Oil Pump

The oil pump circulates oil throughout the engine to lubricate the moving parts.

Fuel Injection System

The fuel injection system delivers fuel to the cylinders. It consists of a fuel pump, fuel injectors, and a fuel rail.

Ignition System

The ignition system produces the spark that ignites the fuel in the cylinders. It consists of a coil, spark plugs, and an ignition module.

Exhaust System

The exhaust system removes exhaust gases from the engine. It consists of an exhaust manifold, catalytic converter, and muffler.

Cooling System

The cooling system keeps the engine from overheating. It consists of a radiator, water pump, and thermostat.

Electrical System

The electrical system provides power to the engine and its components. It consists of a battery, alternator, and starter.
