Charge intake system for a multi-intake valve per cylinder engine
This paper describes a charge intake system for an automotive type internal combustion engine having intake manifolding connected to an engine cylinder head, including, the head having a pair of side-by-side charge intake ports for each cylinder therein, the manifolding including a single air flow containing runner extending towards the head and having a bifurcated portion within the head to form a pair of separate air flow passages connecting the runner to the pair of ports in a siamesed manner, a bore extending through the head transverse to and intersecting all of the intake passages, and a one--piece barrel type valve member extending through the length of the bore, the valve member containing throttle valve type elements electively located in the passages for controlling charge flow into the ports and rotatable between passage opening and blocking positions, the runner containing fuel injection means axially positioned upstream of the bifurcated portion for spraying fuel equally into the pair of passages.
