Description
Technical Field
The utility model relates to a combustion engine technical field especially relates to a take side oil and gas separator of preseparation function.
Background
To balance the pressure in the crankcase of an internal combustion engine, crankcase ventilation systems are designed to balance the internal pressure, which operate by providing a passage in the crankcase that communicates with the atmosphere, thereby balancing the pressure in the crankcase. However, the gas in the crankcase of the internal combustion engine contains a large amount of oil mist, and cannot be directly discharged into the atmosphere to be subjected to oil-gas separation, wherein a device for realizing the oil-gas separation is called an oil-gas separator.
The air-oil separator is one of the key parts of the internal combustion engine for balancing the pressure of the crankcase, and is usually arranged on the cylinder cover because the cylinder cover inner cavity of the engine is communicated with the crankcase and the cylinder cover is at a high position.
In the running process of the engine, high-temperature and high-pressure gas in a combustion chamber inevitably enters a crankcase through a piston ring gap, so that the temperature and the pressure in the crankcase are increased, and engine oil is deteriorated in severe cases, so that the abrasion of the engine is aggravated, and the service life is shortened.
When the gas-oil separator is arranged on the side surface of the engine, a gas outlet needs to be designed from the side surface of the engine body to guide gas in the crankcase into the gas-oil separator. Usually, more cylinder cover return oil 5 flows back to an oil pan along the side face of the engine body, the pressure in the crankcase is higher than the atmospheric pressure, the gas with the high pressure can blow the return oil near the air outlet into the oil-gas separator, so that the oil-gas separation is unclear, the separation efficiency is reduced, and the unseparated oil mist can be directly exhausted into the atmosphere after passing through the oil-gas separator, so that the oil consumption is increased and the environment is polluted.
As shown in fig. 1, the existing oil-gas separator arrangement structure generally comprises a cylinder head cover 1, a connecting pipe 2 and an oil-gas separator 3. The cylinder cover 1 is provided with a protruding air outlet which is communicated with the oil-gas separator 3 through the connecting rubber tube 2, and obviously, the whole height of the engine is increased by the arrangement.
As shown in fig. 2, in the arrangement structure of the V-shaped engine side oil-gas separator, the oil-gas separator 3 is arranged on the side surface of the cylinder block 4, the arrangement does not additionally increase the external dimension of the engine, but the cylinder head return oil 5 port 5 can flow back to the oil pan along the side surface of the cylinder block 4, because the cylinder block oil-gas outlet 6 is also arranged on the side surface of the engine, and the crankcase pressure can be higher than the atmospheric pressure, the return oil flowing through the vicinity of the cylinder block oil-gas outlet 6 can be carried out by the oil-gas with higher pressure in the crankcase and enter the oil-gas separator 3, resulting in the reduction of the separation efficiency of the oil-gas separator 3, and a large amount.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
