Kind Code:
A1
Abstract:
Disclosed is a filter-plate self-adaptive pressure adjustment oil-gas separation device for an engine. The device comprises a filter-pore separation device and a primary separation device, which are arranged in a mounting slot (101) in a cylinder head cover (100), wherein the mounting slot (101) is provided with a gas inlet hole (102) for receiving an oil-gas mixture in a crankcase; the mounting slot (101) is further provided with an exhaust hole (103) for discharging the separated exhaust gas; and the cylinder head cover (100), the filter-pore separation device and the primary separation device are combined to form a bent oil-gas channel. The filter-plate self-adaptive pressure adjustment oil-gas separation device for an engine can accelerate the oil-gas mixture, and the separated oil droplets flow out through an oil return chamber, thereby having a high separation efficiency and meeting the China VI Engine Emission Standards.
