FUEL INJECTOR

Fuel Injector is a solenoid operated electromagnetic valve, which atomizes the fuel by forcing it through
a small nozzle under high pressure. The injection system used is a timed injection system and the
injection is done close to the inlet valve. The injector operates based on the pulse width signal given
by the ECU. The fuel injector is assembled in the inlet manifold located between the inlet port on the
cylinder head and air filter. It is placed at an angle in the intake manifold so as to give maximum fuel
spray and minimum wall wetting.
The advantages of fuel injection are :
Excellent cold starting
Consistent idling RPM
Good acceleration
Full power output
Exploded view of fuel injector
