Fuel Injectors
Each cylinder is provided with a solenoid-operated injector which sprays fuel towards back of each inlet valve. Each injector is energized through the ignition circuit and grounded through the ECA to complete the circuit. The ECA controls the length of time each injector is open.
The "open" time of the injector governs the amount of fuel delivered. The injectors deliver 1/2 the amount of fuel required for an operating cycle each time they open (twice per cycle).
