ABSTRACT:
An induction system for a multi-cylinder internal combustion engine that improves fuel efficiency and reduces the emission of unwanted exhaust gas constituents, particularly at the low and medium load conditions. The engine induction system comprises a plurality of separate carburetor barrels which, at least under some running conditions, serve cylinders separately from each other through main induction passages. One carburetor barrel is provided with a different fuel discharge system than the other carburetor barrels for accomodating a certain engine operating condition. A separate sub-intake system connects this carburetor barrel with other cylinders not normally served by the particular carburetor barrel in question. This sub-intake system has a substantially smaller cross-sectional area in the main intake system so that the charge drawn into the cylinders through the sub-intake system enters at a substantially higher velocity. This improves combustion by creating turbulence under at least some operating conditions. The ratio of flow between the sub-intake system and the main intake system is controlled by a series of throttle valves. In accordance with this invention constructions are provided for delaying the movement of the throttle valve associated with the other carburetor barrels from that associated with the one carburetor barrel for improving the transitional performance of the engine. In certain embodiments of the invention this delay in movement is accomplished by a resilient connection in the throttle linkage.
