Engine (System Overview)


Engine (System Overview)

An engine is a complex mechanical device that converts one form of energy into another. The combustion process that runs inside an engine turns the chemical energy of fuel into kinetic energy, pushing the pistons down.


Most vehicles on the road today come equipped with an internal combustion engine that burns fuel in order to drive the wheels. The air intake and fuel systems of the engine supply its cylinders with a fuel/air mixture that is then ignited to create the pressure and forces which move the pistons up and down. The pistons rotate the crankshaft that transfers this motion to the wheels via the transmission.

Pistons 

A piston is a cylindrical piece of metal fitting closely within a cylinder in which it moves up and down forced by the combustion process. Connected to the crankshaft via a connecting rod, it causes the crankshaft to rotate.

Crankshaft

The crankshaft is one of the main shafts found in an engine. Being a long steel shaft, it turns the up-and-down motion of the pistons into rotation and transfers it to the transmission.

Ignition system

The job of the ignition system is to supply high voltage to a correct spark plug so it can create spark and ignite the fuel/air mixture. 


Fuel system 

The fuel system feeds the engine with fuel to keep the combustion process running.
