This part converts the linear motion of the pistons into rotational motion, transmitting it to the drivetrain.

  • Importance: Drives the car by connecting with the transmission.
  • Design Variants: Forged or cast, varying in complexity.

4. Camshaft

The camshaft controls the opening and closing of the engine valves.

  • Timing: Essential for synchronized engine operation.

5. Valves

Valves manage the intake of air/fuel and the exhaust exit.

  • Types: Intake and exhaust valves play vital roles in engine efficiency.
  • Materials: Generally stainless or heat-resistant alloys.
