Every Part of a Car Engine

Engine Block

The engine block is the main structural component of the engine. It houses the cylinders, crankshaft, and other major components.

Cylinder Head

The cylinder head is located at the top of the engine block and seals the combustion chambers. It contains the valves, spark plugs, and fuel injectors.

Pistons

The pistons are cylindrical-shaped components that move up and down within the cylinders. They transfer the force of the expanding gases to the crankshaft.

Crankshaft

The crankshaft is a rotating shaft that converts the reciprocating motion of the pistons into rotational motion. It is connected to the transmission, which sends power to the wheels.

Camshaft

The camshaft is a shaft that controls the opening and closing of the valves. It is driven by the crankshaft.

Valves

The valves are located in the cylinder head and control the flow of air and fuel into and out of the cylinders.

Spark Plugs

The spark plugs provide the spark that ignites the air-fuel mixture in the cylinders.

Fuel Injectors

The fuel injectors spray fuel into the cylinders.

Oil Pump

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

Water Pump

The water pump circulates coolant throughout the engine to keep it cool.

Alternator

The alternator generates electricity to power the electrical system of the vehicle.

Starter Motor

The starter motor turns the crankshaft to start the engine.

Flywheel

The flywheel is a heavy disc that is attached to the crankshaft. It helps to smooth out the engine’s operation.

Intake Manifold

The intake manifold is a passageway that delivers air and fuel to the cylinders.

Exhaust Manifold

The exhaust manifold is a passageway that carries exhaust gases away from the cylinders.

Turbocharger

A turbocharger is a device that compresses air to increase the power output of the engine.

Supercharger

A supercharger is a device that uses a belt to compress air to increase the power output of the engine.
