Car Engine Components

Engine Block

The engine block is the main structural component of an engine. It houses the cylinders, crankshaft, and other moving parts. The engine block is made of cast iron or aluminum.

Cylinder Head

The cylinder head is located at the top of the engine block. It contains the valves, spark plugs, and other components that control the flow of air and fuel into and out of the cylinders.

Pistons

The pistons are located inside the cylinders. They move up and down to compress the air and fuel mixture and to create power.

Crankshaft

The crankshaft is located at the bottom of the engine block. It converts the up-and-down motion of the pistons into rotary motion.

Camshaft

The camshaft is located in the cylinder head. It controls the timing of the valves.

Valve Train

The valve train consists of the valves, springs, and pushrods. It opens and closes the valves to control the flow of air and fuel into and out of the cylinders.

Intake Manifold

The intake manifold is located on the side of the engine block. It distributes the air and fuel mixture to the cylinders.

Exhaust Manifold

The exhaust manifold is located on the side of the engine block. It collects the exhaust gases from the cylinders and directs them to the exhaust system.

Turbocharger

A turbocharger is a device that uses exhaust gases to spin a turbine. The turbine compresses the air and fuel mixture before it enters the cylinders. This increases the power of the engine.

Supercharger

A supercharger is a device that uses a belt to spin a compressor. The compressor compresses the air and fuel mixture before it enters the cylinders. This increases the power of the engine.

Fuel Injector

A fuel injector is a device that sprays fuel into the cylinders. The fuel injector is controlled by the engine’s computer.

Spark Plug

A spark plug is a device that creates a spark to ignite the air and fuel mixture in the cylinders.

Conclusion

The car engine is a complex machine with many different components. Each component plays a vital role in the operation of the engine. By understanding the different components of the car engine, you can better understand how your car works.
