  3. 3. Fuel SystemThe fuel systemsupplies the enginewith correct mixture ofair and fuel forcombustion. There arethree types of fuelsystems:– The carburettor system– Petrol injection system– Diesel injection system
  4. 4. Cooling SystemThe two main causes ofheat in an engine are:– The burning of fuel in the combustion process.– Friction caused by the moving parts that rub against each other at speed.
  5. 5. Lubrication SystemThe lubrication system reduces friction and wear between engine parts.It also helps cool the engine by removing heat from internal engine parts.
  6. 6. Other Systems• Drive train system• Steering system• Braking system• Suspension system• Emission control system• Computer system• Body and frame
