A multifunctional oil-gas separator

Abstract

The invention belongs to the technical field of diesel engines, and provides a multi-functional oil-gas separator. The multi-functional oil-gas separator is provided with an air inlet pipe communicated with a supercharger; the front end of the air inlet pipe is communicated with the supercharger; a tapered pipe is arranged at the rear end of the air inlet pipe; the outer sides of the air inlet pipe and the tapered pipe are sleeved with an outer sleeve pipe concentrically arranged with the air inlet pipe and the tapered pipe; the front end opening of the outer sleeve pipe is sealed by a front separation plate which is arranged on the air inlet pipe and the tapered pipe in a sleeved mode; the rear end opening of the outer sleeve pipe is sealed by a rear separation plate which is arranged onthe tapered pipe in a sleeved mode; a middle separation plate is further arranged between the front separation plate and the rear separation plate; the middle separation plate is in a circular shape with a notch; the multi-functional oil-gas separator is further provided with a crank box breather pipe, and the crank box breather pipe is communicated with a cavity between the front separation plateand the middle separation plate; and the wall face of one side of the tapered pipe is further provided with a notch, the notch in the middle separation plate and the notch in the tapered pipe are alternately arranged, and a labyrinth air channel is formed. The multi-functional oil-gas separator reduces the consumption of diesel, and the economical efficiency of the diesel engine is improved.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to a multifunctional oil-gas separator. Background technique [0002] The oil-gas separator is a device that separates the high-temperature oil-gas mixture in the crankcase into oil and gas. This device can effectively reduce the pressure in the crankcase, prevent the excessive pressure of the crankcase from affecting the operation of the diesel engine, and avoid high temperature in the crankcase. The oil-air mixture is directly discharged into the atmosphere to pollute the environment and reduce the engine oil consumption rate. Common oil-gas separators have relatively single functions and have problems such as low efficiency, large volume, and complex structure, which cause great inconvenience to the spatial arrangement of diesel engines. [0003] The function of the oil-gas separator in the prior art is relatively single, and only plays the role of oil-gas sep...
