Fuel Injection System

Fuel injection system refers to the set of automotive part which mix fuel with air in an internal combustion engine. The primary component of this system is the fuel injector, which is a computer controlled valve. When pressurized fuel is supplied to it, it delivers fine droplets of fuel and air mixture into the combustion chamber of the engine. It's a sophisticated piece of machinery and can open and close multiple times within a second. The quantity of the fuel supplied to the engine is determined by amount time the fuel injector stays open. This function is electronically controlled. The system also makes use of a lot of sensors to ensure that the right amount of fuel is sprayed into the cylinders.
