1. Introduction
has called internal engine crankcase ventilation system, the role of the crankcase blow-by gas, introduced into the combustion chamber again participate in the combustion.
2. Details
The blow-by gas mainly composed of oil vapor and the composition of the combustible mixture, a viscous oil, if directly into the intake duct just might intake pipe wall adhesion may produce coke hinder intake. And may be glued to the rear and a throttle valve. The oil vapors are not discharged by the pressure of their own, but by the intake manifold negative pressure extraction, so that due to the above problems should, appears in the oil pot breathable modified car body. Structurally, it is divided into two working chambers, is provided to the lower oil chamber precipitation, connected by a duct, separated combustible mixture in the chamber, the final cleaning of the mixed gas is introduced into the intake manifold. In this way not only environmentally friendly, without causing adhesions oil inlet, it can only prevent the formation of coke and coke can not be cleared.
