What are all the parts of a car engine?
Engine block
The engine block is the main structural component of the engine. It houses the cylinders, crankshaft, camshaft, and other internal components.
Cylinder head
The cylinder head is mounted on top of the engine block and forms the combustion chambers. It contains the valves, spark plugs, and injectors.
Pistons
The pistons are cylindrical-shaped components that move up and down inside the cylinders. They compress the air-fuel mixture and transmit the force of the explosion to the crankshaft.
Connecting rods
The connecting rods connect the pistons to the crankshaft. They translate the up-and-down motion of the pistons into the rotational motion of the crankshaft.
Crankshaft
The crankshaft is a rotating shaft that converts the up-and-down motion of the pistons into rotary motion. It is connected to the transmission and drives the wheels.
Camshaft
The camshaft is a shaft that controls the timing of the valves. It rotates at half the speed of the crankshaft and opens and closes the valves at the appropriate times.
Valves
The valves are located in the cylinder head and control the flow of air and fuel into and out of the cylinders. They are opened and closed by the camshaft.
Spark plugs
The spark plugs generate the spark that ignites the air-fuel mixture in the cylinders. They are located in the cylinder head and are connected to the ignition system.
Injectors
The injectors spray fuel into the cylinders at the appropriate time. They are located in the cylinder head and are controlled by the engine management system.
Oil pump
The oil pump circulates oil throughout the engine to lubricate the moving parts and cool the engine.
Water pump
The water pump circulates coolant through the engine to remove heat.
Alternator
The alternator generates electricity to power the electrical components of the vehicle.
Starter motor
The starter motor starts the engine by turning the crankshaft.
Flywheel
The flywheel is a heavy metal disk that is attached to the crankshaft. It helps to smooth out the engine’s operation and provides inertia to keep the engine running.
Manifolds
The manifolds are tubes that connect the engine to the exhaust system and the intake system. The exhaust manifold carries the exhaust gases away from the engine, while the intake manifold delivers air and fuel to the cylinders.
Turbocharger
A turbocharger is a device that uses exhaust gases to spin a turbine that compresses the air-fuel mixture. This increases the power output of the engine.
Supercharger
A supercharger is a device that uses a belt or gears to drive a compressor that compresses the air-fuel mixture. This increases the power output of the engine.
