IAW system warning indicator Single Port Injection System is applied on the vehicle equipped with 3 way catalyst converter .the system insures air/fuel mixture ratio in the vicinity of the ideal air/fuel ratio. The ideal air/fuel ratio is important for catalyst converter to work normally. The aim having the catalyst converter installed is to reduce harmful exhaust emission. Theλsensor, analyzing oxygen content in exhaust Fuel system(fuel pump, fuel filter, pressure regulator) offers the fuel of 1 bar to fuel injector. intake manifold synchronously with TDC . under some specified condition , the amount of fuel needed for Ignition controller with inductive discharging is of electrostatic discharge type(distributorless).
