Combustion air control device for IC engine

摘要

The device has a throttle flap (4) with a bypass channel (11). The channel is connected to air-surrounded fuel injection valves (10), and passes over the chamber (7), which is gasketed relative to the atmosphere. The throttle flap shaft (5) projects into the chamber and is connected to an actuator device (12) for controlling a valve unit (13). The actuator device is a control cam (14), which acts directly or via an intermediate lever, on the valve unit. Alternately, the device may be a rotary slide, which forms part of the valve unit and closes an aperture of the bypass channel.
