What Does a Car Engine Consist Of?

1. Engine Block

The engine block is the main structural component of the engine. It houses the cylinders, crankshaft, camshaft, and other internal components. The engine block is typically made of cast iron or aluminum alloy.

2. Cylinder Head

The cylinder head is a metal casting that covers the top of the cylinders. It contains the valves, spark plugs, and other components that control the flow of air and fuel into and out of the cylinders.

3. Pistons

Pistons are cylindrical-shaped metal components that move up and down within the cylinders. They are connected to the crankshaft by connecting rods.

4. Crankshaft

The crankshaft is a metal shaft that converts the reciprocating motion of the pistons into rotational motion. It is connected to the flywheel, which helps to smooth out the engine’s power output.

5. Camshaft

The camshaft is a metal shaft that controls the opening and closing of the valves. It is driven by the crankshaft.

6. Valves

Valves are metal components that control the flow of air and fuel into and out of the cylinders. They are opened and closed by the camshaft.

7. Spark Plugs

Spark plugs are electrical components that provide the spark that ignites the air-fuel mixture in the cylinders.

8. Fuel Injector

Fuel injectors are electrical components that spray fuel into the cylinders.

9. Oil Pump

The oil pump is a mechanical component that circulates oil throughout the engine to lubricate the moving parts.

10. Water Pump

The water pump is a mechanical component that circulates coolant throughout the engine to keep it cool.
