Assisted air control valve

The valve is mounted directly on the inlet hose upstream of the throttle (electronic throttle module) and is connected to a hose which via a distributor pipe supplies the air surrounded injectors with air.

The valve has its own driver stage and solenoid and is supplied with 12V. The valve is continuously controlled by the engine control module (ECM) with a variable duty cycle which opens or closes a shutter in the valve.

The valve operates most during a cold start and when idling to minimize Carbon monoxide (CO) and hydrocarbon (HC) emissions while retaining performance and driveability. This depends partially on the fact that the fuel mixed with the air has a smaller droplet size and does not fasten to the intake manifold walls when these are cold and damp. The fuel consumption and warming up period for both the engine and the catalytic converter are also minimized at cold start.

The total calculated amount of air to be introduced into the combustion chamber is divided between the throttle (electronic throttle module) and the Assisted air control valve The input signals to the engine control module (ECM) which affect the control of the Assisted air control valve. throttle position, engine speed (RPM)/position sensor, engine coolant temperature (ECT) sensor, ambient air pressure and ambient air temperature.
