Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separation, in particular to an oil-gas separation structure for an automobile engine. Background Art

[0002] When the car engine is working, a part of the exhaust gas will escape through the piston ring into the crankcase. This part of the exhaust gas will then be separated into oil and gas by the crankcase ventilation system. The separated gas will enter the combustion chamber through the engine intake system and be reorganized for combustion, while the separated oil will flow back to the oil pan through the oil return channel of the crankcase ventilation system.

[0003] After searching, the application with patent application number CN201810337413.7 discloses an engine oil-gas separator, including a shell, an oil-gas separation spiral tube, an air inlet pipe, an air outlet pipe and an oil return pipe. The shell is provided with an oil-gas separation spiral tube, the top of the shell is provided with an air outlet pipe, the bottom is provided with an air inlet pipe and an oil return pipe, the air inlet pipe is connected to the bottom of the oil-gas separation spiral tube, the air outlet pipe is connected to the top of the oil-gas separation spiral tube, the passages of the air inlet pipe and the air outlet pipe are isolated from the inner cavity of the shell, the passage of the oil return pipe is connected to the inner cavity of the shell, and the lower side of the oil-gas separation spiral tube is provided with an oil leakage hole connected to the inner cavity of the shell. The present invention provides an engine oil-gas separator with a reasonable structure. By arranging the oil-gas separation spiral tube in the shell, the flow channel length of the oil and gas is extended as much as possible within the limited layout space of the shell, the adsorption area and length of the oil droplets are increased, and the oil-gas separation effect is improved;

[0004] The above application document increases the adsorption area and length of the oil bottom by setting a spiral separation tube in the inner oil-gas separator to ensure the oil-gas separation effect. However, since there is an oil leakage hole on the tube body, the oil adsorbed on it will move downward along it, while the gas is transmitted upward. However, since the oil and gas are discharged upward, some oil and gas with oil bodies are still discharged, and the oil-gas effect is limited.

[0005] Therefore, we propose an oil-gas separation structure for an automobile engine. Utility Model Content
