Eclipse Spyder FWD L4-2350cc 2.4L SOHC 16 Valve (1996)
EGR Valve: Description and Operation
PURPOSE/OPERATION
The EGR Valve allows a measured amount of exhaust gas to be recycled into the intake flow. The valve has a diaphragm with a pintle rod attached
to one side of it and a spring pushing on the other side of it (keeping the valve closed). When vacuum is applied to the diaphragm, it overcomes the
spring pressure, pulling the pintle rod out of it's seat. This opens the passage, allowing gas recirculation. The amount of recirculation is directly
relative to ported vacuum (throttle opening).
