Basic Car Engine Diagram

Engine Components

Cylinder: The cylindrical chamber in which the piston moves up and down.
Piston: The cylindrical metal part that moves up and down in the cylinder, compressing and expanding the air-fuel mixture.
Connecting rod: The metal rod that connects the piston to the crankshaft.
Crankshaft: The rotating shaft that converts the linear motion of the pistons into rotary motion.
Camshaft: The shaft that operates the valves that open and close the intake and exhaust ports.
Valves: The metal flaps that open and close the intake and exhaust ports.
Intake manifold: The passageway that carries the air-fuel mixture from the carburetor or fuel injector to the cylinders.
Exhaust manifold: The passageway that carries the exhaust gases from the cylinders to the muffler.

Intake stroke: The piston moves down the cylinder, drawing the air-fuel mixture into the cylinder.
Compression stroke: The piston moves up the cylinder, compressing the air-fuel mixture.
Power stroke: The spark plug ignites the air-fuel mixture, creating a small explosion that forces the piston down the cylinder.
Exhaust stroke: The piston moves up the cylinder, pushing the exhaust gases out of the cylinder.

There are two main types of car engines:

Gasoline engines are more common in passenger cars, while diesel engines are more common in trucks and buses.

Regular engine maintenance is essential for keeping your car running smoothly and efficiently. Some of the most important maintenance tasks include:

Changing the oil and filter: This should be done every 3,000 to 5,000 miles.
Replacing the spark plugs: This should be done every 30,000 to 60,000 miles.
Replacing the timing belt or chain: This should be done every 60,000 to 100,000 miles.
Having the engine tuned up: This should be done every 30,000 to 60,000 miles.

By following these maintenance tips, you can help keep your car’s engine running smoothly for many years to come.
