Embodiment

[0017] Example: such as figure 2 As shown, a transverse partition 11 and a medial partition 12 connected to it are provided on the inner side of the coaming plate arranged on the cylinder head cover. Wherein the mediastinum 12 comprises a vertical curved body and an arc body connected with it in a shape adapted to the lower part of the coaming plate waist, and a mediastinum guide plate 7 is obliquely provided at the junction of the two parts, and a mediastinum guide plate 7 is arranged obliquely at the tail of the arc body. A guide plate 6 arranged substantially parallel to the transverse partition 11; a waist partition 9 is also provided on the inner side of the coaming, and the waist partition 9 is basically parallel to the transverse partition 11; a waist partition guide plate 8 is obliquely provided at the end of the waist partition 9. The end points to the intersection of the transverse septum 11 and the mediastinum 12 or near the intersection, and a cylinder is provided...

Abstract

The invention relates to a labyrinth oil-gas separation device for an engine cylinder head cover, which comprises a coaming plate arranged on the cylinder head cover, a transverse partition and a longitudinal septum connected with it are arranged on the inner side of the coaming plate, and on the coaming plate A waist partition is also provided, and a waist partition guide plate is obliquely arranged at the end of the waist partition, and the above partitions are fixed together with the cylinder head cover body. The invention has reasonable structure and ingenious design, which can not only make the oil and gas separation more thorough, reduce the original serious failure of burning engine oil, but also reduce the consumption of engine oil, improve the performance of the engine, improve the emission performance, reduce pollution, and be more beneficial environmental protection.

Description

technical field [0001] The invention relates to an oil-gas separator for an engine, in particular to a labyrinth oil-gas separator for an engine cylinder head cover. Background technique [0002] The cylinder head cover is located on the upper part of the engine and is connected with the cylinder head. Its function is to discharge the exhaust gas in the cavity in time when the engine is running, and prevent the oil in the cylinder head from seeping out. The role of separation. But there are some problems in the oil-gas separation device of the cylinder head cover of the prior art, such as the single design of the dividing plate, and the formed labyrinth exhaust channel path is simple (as figure 1 shown). In this way, the oil droplets contained in the gas have a small collision area and frequency with the separator during the discharge process, and lack of sufficient centrifugal force, the separator is not easy to hang beads, so the separation is not complete, not only seri...
