Method for recycling crankcase gasses into the inlet manifold of an engine has an internal wall with ducts to evenly mix the gasses with fresh air

摘要

A method for recycling crankcase gasses in an IC engine has the gasses ducted into a collecting chamber and mixed with fresh air before being passed into the inlet manifold. The gas flow system incorporates a separating wall with gas ducts to ensure an even mixing of the gasses with fresh air. The separating wall can be assembled from shaped plates which are welded together. The outer shell of the gas mixing system is made from sections which are cold welded together.
