Abstract

The invention discloses a cylinder cover-built-in oil-gas separation system. The cylinder cover-built-in oil-gas separation system comprises a built-in oil-gas separator and a breather assembly, wherein the built-in oil-gas separator comprises a cover body, and a labyrinth cavity and a bottom cover which are arranged on one side of the cover body; a gas outlet connecting pipe which extends to theouter part of the cover is arranged at one end of the labyrinth cavity; a breather socket is formed in the top of the labyrinth cavity; a rough filtration pore plate, a roundabout rectification structure, a fine filtration pore plate and a separation plate are arranged in the labyrinth cavity; the rough filtration pore plate is arranged between an inlet pore plate and the roundabout rectificationstructure; the fine filtration pore plate is arranged at the downstream part of the roundabout rectification structure; the separation plate is arranged at the downstream part of the fine filtration pore plate; the inlet pore plate is arranged at one end of the bottom cover; the breather assembly comprises a shell, and a membrane and a spring which are arranged in the shell; and a plug is arrangedat the lower end of the shell. According to the cylinder cover-built-in oil-gas separation system, engine oil can be effectively prevented from going bad, and oil is prevented from leaking from a crankshaft oil seal and a crankcase gasket.

Description

technical field [0001] The invention relates to the field of engines, in particular to an oil-gas separation system built into a cylinder head cover. Background technique [0002] When the engine is working, part of the combustible mixture and exhaust gas will escape into the crankcase through the piston ring, and the gasoline vapor condensed into the crankcase will make the engine oil thinner and the performance will deteriorate. The exhaust gas contains water vapor and sulfur dioxide. The water vapor condenses in the engine oil to form foam, which damages the oil supply. This phenomenon is especially serious in winter; sulfur dioxide meets water to form sulfurous acid, and sulfurous acid forms sulfuric acid when it meets oxygen in the air. The appearance of oil not only deteriorates the oil, but also corrodes the parts. As the combustible mixture and exhaust gas escape into the crankcase, the pressure in the crankcase will increase, and the oil will seep from the cranksha...
