MPV 2WD V6-3.0L SOHC (1992)
Fuel Injector: Description and Operation
Injectors With Fuel Rail
Typical Fuel Injector
PURPOSE
Electrically operated valves that permit precise metering of fuel into the intake system.
LOCATION
On intake manifold near heads.
OPERATION
Fuel injectors are electrically operated solenoid valves that open when energized. Injectors receive battery power from the main relay when the
ignition is at either "START" or "RUN" position. They are energized when the ECU completes the circuit to ground. Injection timing and
duration are determined by the ECU.
CONSTRUCTION
Constructed of stainless steel and high density plastic to resist corrosion. They consist of a fuel inlet with filter screen, an electrical solenoid and
connector, and a pintle valve and nozzle. Injectors are held in place by the fuel rail and sealed by an O-ring and insulator.
