Problems solved by technology

However, whether it is a cyclone or a baffle structure, the required separation efficiency can only be achieved when the blow-by flow rate reaches a predetermined value.
Therefore, when the engine is running at a small speed, the flow rate of the blow-by gas cannot reach the predetermined value. In this case, the oil-gas separation rate cannot meet the demand
[0004] Therefore, in the existing oil-gas separation structure, simple structure and stable oil-gas separation efficiency cannot be balanced

Abstract

The invention relates to an oil-gas separating structure, an engine cylinder cover and an engine. The oil-gas separating structure comprises a pore plate (1) and a flow blocking structure, wherein gasinlet pores (11) used for the entry of crankcase blow-by gas into the oil-gas separating structure are formed in the pore plate (1); the flow blocking structure is provided with an oil-gas separatingsurface (21); the oil-gas separating surface (21) comprises an impact zone of oil drops in the crankcase blow-by gas; and the flow blocking structure is configured to ensure that the area of the impact zone can be inversely proportionally changed along with the flow rate of the crankcase blow-by gas which enters the oil-gas separating structure. Through the above technical scheme, the oil-gas separating structure provided by the invention is simple, and the stable oil-gas separating efficiency can be achieved.

Description

technical field [0001] The present disclosure relates to the field of engines, in particular to an oil-gas separation structure for engine crankcase blow-by gas and the engine. Background technique [0002] When the engine is working, part of the combustible mixture and combustion products will escape from the cylinder to the crankcase through the piston ring, forming crankcase blow-by gas. Since the unburned fuel gas, water vapor and exhaust gas contained in the blow-by gas will dilute the oil, reduce the performance of the oil, and accelerate the oxidation and deterioration of the oil, therefore, it is necessary to separate the oil and gas from the blow-by gas to prevent oil droplets from entering The intake system produces carbon deposits, which in turn affects engine performance. [0003] Existing engines are usually equipped with an oil-gas separation structure to separate crankcase blow-by gas. Traditional oil-gas separation structures mainly include labyrinth baffle ...
