GAS DISTRIBUTION STRUCTRUE FOR INTAKE MANIFOLD OF ENGINE

摘要

According to the present invention, when supplying additional gas such as EGR gas, purge gas, or the like except for common air to a combustion chamber through an intake manifold of an engine; the additional gas is able to evenly be more supplied to each combustion chamber. Moreover, a volume of an intake system is minimized to improve vehicle loading properties of an engine with compact composition of the engine, and a weight of the intake system is reduced to improve fuel efficiency. According to the present invention, a gas distribution structure for an intake manifold of an engine comprises: an intake manifold; a gas distribution pipe; and a plurality of protruding pipes.
