    See Emissions Details
This electromagnetic valve meters fuel into the intake manifold proportional to the air being induced into the engine. When the valve is energized, the electromagnetic force generated by the solenoid lifts the pintle/ball from the seat. Fuel under pressure is then injected into the throttle body bore. For throttle body injection, a hollow conical spray is required to aim the metered flow around the throttle valve.
