Labeled Car Engine Parts Names with Pictures
Engine block
The engine block is the main structural component of an internal combustion engine. It houses the cylinders, crankshaft, and other critical components.
Cylinder head
The cylinder head is located at the top of the engine block and seals the combustion chamber. It contains the valves, spark plugs, and other components that control the flow of air and fuel into and out of the cylinders.
Pistons
Pistons are cylindrical-shaped components that move up and down inside the cylinders. They compress the air-fuel mixture and transfer the force of combustion 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 and rotates at half the speed of the crankshaft.
Valves
Valves are mushroom-shaped components that control the flow of air and fuel into and out of the cylinders. They are opened and closed by the camshaft.
Spark plugs
Spark plugs are devices that generate an electrical spark to ignite the air-fuel mixture in the cylinders.
Fuel injectors
Fuel injectors are devices that spray fuel into the cylinders. They are controlled by the engine’s computer.
Intake manifold
The intake manifold is a passageway that delivers air and fuel to the cylinders. It is connected to the carburetor or fuel injector.
Exhaust manifold
The exhaust manifold is a passageway that carries exhaust gases away from the cylinders. It is connected to the catalytic converter and muffler.
Turbocharger
A turbocharger is a device that increases the power of an engine by compressing the air that enters the cylinders. It is driven by exhaust gases.
Supercharger
A supercharger is a device that increases the power of an engine by compressing the air that enters the cylinders. It is driven by a belt or chain from the crankshaft.
