Problems solved by technology

The cost of the plug-in type is low, but it takes up more space and is not easy to arrange; the structure of the integrated type is more complicated, and the oil return efficiency is not high
When the engine actually arranges the oil-gas separator, due to the lack of suitable installation holes or space interference, the arrangement is relatively low, which is prone to the risk of clogging and oil leakage

Abstract

The invention discloses an external labyrinth type oil-gas pre-separator which is arranged on a cylinder block cover plate. The external labyrinth type oil-gas pre-separator comprises a prefilter baseplate, a prefilter shell, a plurality of transverse baffle plates and a longitudinal baffle plate. The prefilter base plate is arranged clinging to the cylinder block cover plate, the prefilter shellis buckled to the prefilter base plate, and the prefilter base plate and the prefilter shell form an accommodating space which has a certain thickness and is relatively closed; the transverse baffleplates are successively and parallelly arranged on the front side walls of the prefilter base plate and the prefilter shell in a staggered manner, and the transverse baffle plates form an S-shaped channel in the accommodating space; the longitudinal baffle plate is arranged at the rightmost end of the front side wall of the prefilter shell and is vertical to the transverse baffle plates, the longitudinal baffle plate is connected to the rightmost transverse baffle plate among the transverse baffle plates and forms a cavity with the upper side wall and the right side wall of the prefilter shell, and the cavity communicates to the S-shaped channel. The external labyrinth type oil-gas pre-separator can separate oil from gas quickly and smoothly through the internal S-shaped channel.

Description

technical field [0001] The invention relates to the field of engines, in particular to an external labyrinth type oil-gas pre-separator. Background technique [0002] When the engine is working, the high-pressure combustible mixture and burned gas in the combustion chamber will more or less leak into the crankcase through the gap between the piston group and the cylinder, causing blow-by. The components of blow-by gas are unburned fuel gas, water vapor and exhaust gas, etc., which will dilute the engine oil, reduce the performance of the engine oil, and accelerate the oxidation and deterioration of the engine oil. Moisture condenses in the engine oil, which will form sludge and block the oil circuit; the acid gas in the exhaust gas will be mixed into the lubrication system, which will cause corrosion and accelerated wear of engine parts; blow-by gas will also cause the pressure of the crankcase to be too high and damage the crankcase. Sealed to allow oil to leak out. [00...
