[5] INJECTORS AND DELIVERY PIPE
(WG1605-G-E3, WG1605-GL-E3)
The gasoline fuel delivery system, utilizes a delivery
pipe (1) mounted with injectors (2), for each cylinder. The
Engine Control Unit (ECU) will utilize the gasoline fuel
delivery calibrations, to pulse width modulate each
injector (2), to deliver the correct amount of gasoline, for
optimized performance and emission control. The
injector pulsing or "firing" is accomplished by supplying a
12 volt supply, to the positive side of the injector coil, and
switching the ground circuit side, using the injector
drivers, internal to the ECU. Injectors (2) are an
emissions control device, and do not require periodic
adjustment.
