Engine System ।। Vehicle system ।।

 Engine System one of the most important system of vehicle because engine provides energy to Run and without energy we can't run vehicle.

An engine is a machine designed to convert one or more forms of energy into mechanical energy.  

Engine System

Compared to primitive earlier automobile engines, today's engine can be an intimidating design experience. Earlier engines were designed with basic components; today's engines must perform to the highest efficiency while producing the highest power output. The modern engine is designed with computer- monitored fuel injection systems, and electronically controlled timing. More accessories result in more complexity and thus more difficulty in the integration of the engine system.

Typical combustion engines are started using electricity supplied by a 12 volt battery to a starter motor. The starter motor cranks the engine's flywheel while electrical current is sent to the spark plugs and fuel pump. Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. The four strokes are: intake, compression, combustion, and exhaust.

 The intake stroke fills the cylinder with a fuel and air mixture.

 Then second stroke compresses the mixture.

 The spark plug fires and ignites the fuel, causing the piston to make its third stroke; it is this stroke that powers the vehicle. 

On the fourth stroke, the burned gases are sent out through the exhaust system.
