Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, and particularly to an oil-gas separator for an engine. Background Technique

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, an internal combustion engine usually converts chemical energy into mechanical energy. An engine is applicable to power generating devices and can also refer to the entire machine including the power device. An oil-gas separator is a main component in the crankcase ventilation system, which efficiently separates the oil in the crankcase blow-by gas. Its separation performance has an important impact on the reliability and emissions of the engine. When the engine is operating normally, a part of the unburned combustible mixture and combustion exhaust gas in the cylinder enter the crankcase through three channels. These blow-by gases will increase the temperature in the crankcase and increase the evaporation rate of the engine oil in the oil pan. Since some components in the crankcase are lubricated by splash lubrication, when the oil mist generated by splash lubrication in the crankcase and the oil vapor evaporated at high temperature are mixed with the cylinder blow-by gas, a very fine aerosol with most particle sizes less than 1 μm will be formed. This is the formation process of the oil-gas mixture in the crankcase blow-by gas, and the function of the oil-gas separator is to effectively separate the oil and gas.

[0003] When installing the oil-gas separator, the intake pipe and the exhaust pipe need to be connected to the intake port and the exhaust port on the oil-gas separator respectively. However, when connecting, connecting hoses and spring clips are required. The two ends of the connecting pipe are respectively sleeved on the outer walls of the intake pipe and the intake port. One hand holds the connection position tightly, and the other hand uses a tool to open the spring clip and clamp the spring clip on the outer wall of the connecting pipe to fix the two ends of the connecting pipe on the outer walls of the intake pipe and the intake port. The operation is relatively complex. In order to achieve the purpose of conveniently connecting the intake pipe and the exhaust pipe to the intake port and the exhaust port, an oil-gas separator for an engine is provided. Content of the Utility Model
