Japanese Patent JPS6326266
Kind Code:
B2
Abstract:
In a V-type internal combustion engine, an auxiliary air supply apparatus includes an auxiliary air distribution pipe which communicates directly to two or more mutually independent chambers in the intake system of the engine. This auxiliary air distribution pipe is connected and communicates to an auxiliary air channel so as to bypass an intake throttle valve. In this auxiliary air channel an auxiliary air control valve is installed to control the volume of auxiliary air flowing through the channel, according to the operating condition of the engine. Because of this, the auxiliary air controlled by the control valve is directly distributed to two or more chambers through the auxiliary air distribution pipes.
