Kia Optima: Injector. Description and Operation
Description
Based on information from various sensors, the ECM can calculate
the fuel amount to be injected. The fuel injector is a solenoid-operated valve
and the fuel injection amount is controlled by length of injection time. The
ECM controls each injector by grounding the control circuit. When the ECM energizes
the injector by grounding the control circuit, the circuit voltage should be
low (theoretically 0V) and the fuel is injected. When the ECM de-energizes the
injector by opening control circuit, the fuel injector is closed and circuit
voltage should momentarily peak, and then settle at system voltage.
