What is a fuel injector
Fuel injector is a devise used for supplying fuel into an engine. It has become the primary fuel delivery system used in engines, having replaced carburetors. Fuel is supplied to the injectors through fuel pump. Each fuel injector is fitted on the cylinder head above each cylinder. The injectors are made of good quality material to with stand the high temperature and pressure during combustion process.
Where does fuel injector located
The fuel injector is located in the intake manifold because fuel is sprayed directly at the intake valves. A fuel supply rail connects all the fuel injectors to the fuel supply.
