Beschreibung
Zusammenfassung:	The invention relates to an engine cylinder cover shield. An oil and gas separation room is arranged in the inner surface of the cylinder cover shield; the oil and gas separation room comprises a first oil and gas separation room located in a gas inlet side and a second oil and gas separation room located in an exhaust side; the first oil and gas separation room is of a four-stage separation structure; and the second oil and gas separation room is of a three-stage separation structure. According to the engine cylinder cover shield, the four-stage separation structure is adopted, and a cyclone separation plate assembly structure is added, so that when oil and gas mixed gas passes a cyclone separation plate assembly, a vortex is produced by airflow due to the arrangement of curve plates; since the densities of oil and gas are different, the oil and the gas are separated under the effect of the vortex, large oil drops directly drop on oil baffle plates after being separated, small oil drops impact the surface of a cyclone separation plate and flow to hole plates along the surface of the cyclone separation plate, and the oil and gas separation effect is improved.
