• Valves

  There are a number of valves that help maintain the operation and efficiency of your car’s engine. Fuel-air mix is allowed into the combustion chamber by the intake valve, and the burnt fuel-air mix is released into the exhaust system by the exhaust valve release. Replacing these valves can be quite a difficult process, because the cylinder head must be detached and taken apart.

• Flywheel

  The flywheel is a heavy metal disk that connects the engine to the clutch. The flywheel can be damaged from wear and tear or warped by the heat of the friction. The more stress on the engine, the more wear the flywheel suffers.

• Supercharger

  A supercharger increases engine power by boosting the pressure of the air provided to the engine. This increased air allows more fuel to be burned, which increases the power. The supercharger is called a turbo-supercharger (turbo) if it’s powered by a turbine from the exhaust.
