Digital EGR System

The digital EGR valve is designed to accurately supply EGR to the engine, independent of intake manifold vacuum. The valve controls EGR flow from the exhaust to the intake manifold through 3 orifices, to produce 7 different combinations. When a solenoid is energized, the armature, with attached shaft and swivel pintle is lifted, opening the orifice.
