Description

Fine separation mistake proofing structure

Technical Field

The utility model relates to a crankcase ventilation technical field especially relates to a smart separation mistake proofing structure.

Background

Energy conservation and emission reduction become common subjects of the automobile industry in the world, and strict emission regulations continuously improve the performance requirements of crankcase ventilation systems of automobiles. The oil-gas separator is an essential functional component forming a crankcase ventilation system in a plastic valve chamber cover, and has important influence on the stability and safety of the engine operation. When the engine works, a part of high-temperature and high-pressure fuel gas leaks into a crankcase through a piston ring, wherein after gasoline vapor and water vapor are condensed, engine oil becomes thin, the performance is deteriorated, foams are formed in the engine oil to damage the normal supply of the engine oil, and the phenomenon is particularly serious when the engine is cooled in winter. After the oil-gas separator is installed, engine oil in oil gas discharged from a crankcase can be separated and reserved back to an oil pan, so that after the oil-gas separator is separated, mixed waste gas, oil vapor, incompletely combusted CO and other fuel gas enter an air inlet of a supercharger through corresponding pipelines to be mixed with air, and the mixture is pressurized and then enters a human cylinder to be combusted secondarily. Therefore, in the design and development process of the crankshaft ventilation system, the design and performance research of the oil-gas separator is one of the most important links. A fine separation structure exists in the oil-gas separator, and the fine separation structure is an important component for separating oil gas. The precise separation structure is positive and negative, and the separation efficiency is greatly influenced by misloading and reverse loading.

Chinese patent application No. CN201910853863.6 discloses an assembly mistake-proofing structure of a fine separator of an oil-gas separator, which comprises a fine separator body, a fiber cotton body and a support plate. The fine separator body is provided with a right installation mistake proofing column and a left installation mistake proofing column.
