INTAKE MANIFOLD FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to mechanical engineering and can be used for intake systems of internal combustion engines. An annular groove forming internal and external walls is embodied in the end face of each pipe of the internal combustion engine intake manifold around the output hole thereof. The external wall is provided with at least one hole embodied therein and the internal wall has at least two tangential holes which are preferably symmetrically arranged with respect to the longitudinal axis of the output hole and at equal distances from each other. Said invention makes it possible to increase an engine power, reduce fuel consumption by more complete fuel combustion and to substentially decrease exhaust gas toxicity.
