ABSTRACT:
Intake system for a multiple cylinder internal combustion engine having primary and secondary passages leading to each cylinder and respectively provided with throttle valves. The primary passages for the respective cylinders are connected together through a first communicating passage of relatively large cross-sectional area and a second communicating passage of a relatively small cross-sectional area which is downstream of the first passage. One of the primary passages is provided with a shut-off valve which is located close to but downstream of the second communicating passage and adapted to be closed in idling operation or deceleration of the engine for directing the mixture totally toward the cylinder associated with the other primary passage. The primary and secondary passages leading to the same cylinder are connected together by a connecting passage downstream of the throttle valve. The connecting passage for the primary passage having the shut-off valve is located downstream of the shut-off valve so as not to weaken the function of the shut-off valve.
