The Engine

This short movie will give you a brief overview of the 4-stroke engine that is used by most vehicles.

Also called the "Otto" cycle engine, for it’s designer, it is a relatively efficient engine, converting the energy of exploding gasoline into mechanical energy to propel the vehicle.

When you start your car:

  • power from your battery is used to operate a small electric motor called the starter motor
  • the starter motor turns the flywheel and crank shaft of the engine so that the engine can attain sufficient momentum and speed to start and run on its own
  • the crankshaft is inside your engine and supplies power to the remainder of the power train
  • the crankshaft is also connected by connecting rods to pistons inside cylinders
  • exploding gas inside the cylinders drives the pistons up and down and, through the connecting rods, turns the crankshaft
  • inside the cylinders a mixture of gas and air is compressed, ignited by a spark plug , and explodes
  • the mixture of air and gas is delivered to the cylinders by a carburetor and intake manifold or a fuel injection system, which has replaced most cruretors on newer cars
  • The moving parts of your engine must be lubricated. Oil which accumulates in your engine's oil pan is pumped by the oil pump through an oil filter and then through tubes that deliver the oil to the moving parts that need to be lubricated.
