Abstract
A flow accelerating ventilation type head cover may include a baffle separating a lower space which is opened such that blow-by gas containing an oil particle generated from an engine is collected thereto and an upper space which is closed such that the blow-by gas is flowed out to an outside of the engine and having a baffle passage communicating the lower space with the upper space such that the blow-by gas is exhausted from the lower space to the upper space therethrough, and a flow accelerating member being coupled with the baffle passage and being positioned in the upper space so as to accelerate a flow speed of the blow-by gas passing through the baffle passage and thus separate the oil particle by collision effect of impacting the oil particle with each other in the upper space.
