POWER BOOSTER UNDER HIGH LOAD

Details

The Impco Vacuum Power Valve (VPV) is a vacuum operated valve, which is normally open.The VPV is designed to richen the air fuel ratio when the engine is under high load to boost power output. The VPV is mounted in the secondary test port of the regulator and is connected to an air valve vacuum port on the mixer and manifold vacuum. When engine load is low and manifold vacuum is high the VPV is held closed by the strong manifold vacuum signal. When the engine load is high and manifold vacuum is low the weak manifold vacuum signal allows the VPV to open and richen the air fuel ratio. A selection of restrictors is available to custom tailor the amount of fuel enrichment for different size engines.
