TRANSMISSION CONTROLLED THROTTLE FOR INTERNAL COMBUSTION ENGINE

摘要

A fuel supply system for an internal combustion engine utilizing an automatic transmission including a torque converter and a gear train has a carburetor with an inlet passage and a throttle valve therein. A sensing member is in a first position when the gear train is in a neutral position and a second position when the gear train is in a drive position. A throttle valve control slightly opens or closes the throttle valve in response to the sensing member. The throttle valve control operates to slightly open the throttle valve to hold the idling speed of the engine to a predetermined value when the gear train is in the drive position, thereby preventing the engine speed from decreasing due to the load.
