Intake manifold advanced in uniform distribution of PCV gas

Abstract

The present invention provides an intake manifold advanced in uniform distribution of PCV gas. The intake manifold includes a main body, a throttle valve, a gas collection chamber, intake passages and a gas distribution strip. The throttle valve is connected to the main body to supply fuel-air mixture to the main body. The gas collection chamber is arranged in the main body to temporarily store the fuel-air mixture supplied by the throttle valve to the gas collection chamber. The gas collection chamber is provided with a PCV gas supply hole, such that the PCV gas can be pumped to the gas collection chamber again through the PCV gas supply hole by a combustion chamber. The intake passages are arranged around the main body in a streamline shape, such that the fuel-air mixture is uniformly supplied to the combustion chamber from the gas collection chamber. The gas distribution strip is arranged in the gas collection chamber to guide the PCV gas, such that the PCV gas is uniformly supplied to the intake passages. The gas distribution strip is provided with an inlet corresponding to the PCV gas supply hole on a first surface, and a plurality of outlets corresponding to the intake passages on a second surface.

Description

technical field [0001] In general, the present invention relates to an intake manifold having improved performance for uniform distribution of positive crankcase ventilation (PCV) gases; and more particularly, the present invention relates to an intake manifold in which the gas distribution strip ( The distribution bar) is installed in the plenum chamber and has a plurality of air flow passages so that the PCV gas drawn from the cylinder head cover into the plenum chamber is uniformly supplied into the plurality of intake runners , thereby improving the performance of evenly distributing the PCV gas into the intake passage. Background technique [0002] Generally speaking, the function of the intake manifold is to uniformly supply the fuel-air mixture drawn into it from the evaporator to the combustion chambers of the engine used to generate power. Preferably, the intake manifold is configured to reduce resistance to the fuel-air mixture as it flows from the evaporator into...

AI Technical Summary

Problems solved by technology

However, in the conventional technology, it is difficult to achieve the above object because the fuel-air mixture newly introduced into the plenum via the throttle body flows into the plenum at a relatively high speed.
