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 as-
sembled 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
