| 摘要 |
The referenced blow off valve controller (hereafter called BOVC) is an electronic control circuit driving electromechanical valve to control the operating actuator contained in a blow off valve assembly used on turbocharged spark initiated engines to control destructive pressure reflections in the intake track during high boost to lo w boost throttle transitions caused by closing the throttle valve. The BOVC consists of a microprocessor controller including operating software, pressure transducers to monitor pressures within the intake track of said engine, power conditioning circuitry, electromechanical valve drive circuits and 3 way electromechanical valve. Additional status outputs to indicate to the engine operator status of said blow off valve may or may not be incorporated into said BOVC designs are disclosed. Externally adjustable reference potentiometers m ay be incorporated to set operating parameters.
