ABSTRACT:
An internal combustion engine having a relatively large main induction system which supplies a charge to the chambers at higher loads and a relatively small auxiliary induction system that supplies the chamber charge at idle and low loads so as to improve fuel economy and exhaust emission control. A valve arrangement is incorporated for controlling the flow through the induction systems. The valve arrangement includes a manually positioned valve and a valve that is responsive of flow through the induction passages so that an increasing proportion of the charge will be supplied through the main induction system as the air flow increases. A manual override is also included so that the automatically positioned valve will be opened independently of the air flow responsive actuator when the manually operated throttle valve is suddenly opened.
