What Are the Different Car Engine Components?


This article will give you an overview of what makes up a car engine and how it works.


The engine is the most important part of your car. It has many parts, including pistons, crankshaft and camshafts. The engine is connected to the transmission which is connected to the wheels.

Intake manifold

The intake manifold is a part of the engine that supplies fuel and air to each cylinder. It routes fuel and air from outside your car’s engine bay into each cylinder, where it mixes with gasoline before being ignited by spark plugs.

The intake manifold also has other names: inlet manifold, plenum chamber or plenum chamber assembly (PCA).

Exhaust manifold

The exhaust manifold is a part of the engine that allows gases to flow into the exhaust system. It is located between two cylinders, often on top of or below them. The exhaust manifold collects spent fuel and sends it out through various pipes to another component called an exhaust pipe.

When you start your car’s engine, air pressure in each cylinder pushes down on its piston (a metal rod) which forces fuel into an area called a combustion chamber where it mixes with air before being ignited by spark plugs within each cylinder. This process creates energy that turns rotational motion into power for driving your car forward or backward!

The exhaust manifold is made up of rubber seals around its edges so that no leaks occur during operation; however if these seals become damaged then gases may escape from them instead of being pushed out through their intended path which could lead to dangerous situations such as explosions happening inside nearby buildings!

Turbocharger or supercharger

A turbocharger or supercharger is a device that uses exhaust gases to compress air, which in turn forces more air into the engine. This helps it burn more fuel and produce more power, resulting in greater acceleration.

A turbocharger has two main components: an exhaust-driven turbine and a compressor wheel. The turbine spins as hot gas passes through it; this spins the compressor wheel at high speeds, which compresses air before sending it back into your engine’s intake manifold (the part of your car where air enters). A supercharger does not use exhaust gases for power like a turbo does–it uses an external energy source like electricity instead–so it can’t be considered as efficient or powerful as its counterpart


The intercooler is a heat exchanger used to cool the air after it leaves the turbocharger or supercharger. It’s usually mounted at the front of the car where it can get cold air from the front grille and be exposed to direct airflow.

Intercoolers are usually made out of aluminum and have thin fins that increase surface area for heat transfer between air passing through them, which reduces pressure inside and increases efficiency.

Cylinder head

The cylinder head is the top part of your engine. It contains the valves and spark plugs, as well as other components that regulate air flow into your engine. The cylinder head sits on top of the engine block, which houses its cylinders (or pistons).

The cylinder head connects to the engine block via a gasket that seals off any gaps between them so that no fluids can leak out during operation.

Camshafts, lifters and timing chain or belt.

A camshaft is a shaft that controls the timing of valve operation. It is connected to the crankshaft by a timing chain or belt and has lobes that open and close valves at precise intervals. The camshaft determines how fast your engine runs, so it’s important for your vehicle’s performance to have one installed correctly in order for everything else in your car engine to work properly as well.

  • Camshafts are also known as “valve timing gears.”
  • They’re made from hardened steel with an accuracy level of 0.0001″ (0.0025mm).

The engine is the most important part of a car.

The engine is the most important part of a car. It’s what makes the car go, run, and move. The engine is essentially the heart of your vehicle and without it there would be no power or movement.

The engine is what powers your car’s motion by converting fuel into heat and chemical energy through combustion. In order to get things moving in your car’s motor you need to have some kind of spark plug that ignites this process so that everything starts working properly again when you turn on your ignition key (or press down on accelerator pedal).
