Abstract
The utility model discloses a kind of rebreather of engine air outlet oil gas collecting device, its technological scheme is: the outlet of resuscitation apparatus is provided with oil-gas condenser, oil-gas condenser and filtering core device and vacuum pump join successively, are provided with oil collecting case below oil-gas condenser.The pipeline that resuscitation apparatus is exported to the each parts of vacuum pump inlet is sealing pipeline.In order to detect the resistance of crankcase through resuscitation apparatus and oil-gas condenser final vacuum, between resuscitation apparatus and oil-gas condenser and between oil-gas condenser and filtering core device, be equipped with pressure transducer, this sensor and engine electronic control unit ECU join.The vacuum pressure value that ECU can adjust vacuum pump according to pressure reduction or Pressure Drop is to eliminate resistance.This apparatus structure device is simple, takes up room very little, does not substantially affect the layout of adjacent zeros parts.The machine oil of discharging is breathed in collection that can be comparatively complete, has reduced the pollution of oil gas to environment.
Description
Technical field
The utility model belongs to engine components, is specifically related to a kind of rebreather of engine air outlet gas and oil separating plant.
Background technique
In the time that engine crankcase pressure is excessive, the machine oil splashing can, under the effect of pressure, be discharged in air by resuscitation apparatus, causes air-polluting simultaneously, also can increase the consumption of machine oil.The effect of resuscitation apparatus is to ensure that crankcase communicates with atmosphere, prevents that again machine oil runs off.But the transformation of resuscitation apparatus will bring many difficulties, because resuscitation apparatus body, the air inlet/outlet that comprises resuscitation apparatus, return opening and corresponding connecting pipeline, shape and structure complexity, takes up room larger, and after transformation, adjacent component are difficult to arrange with it.In order to the utility model proposes a kind of device that resuscitation apparatus discharge engine oil is reclaimed.
Summary of the invention
The purpose of this utility model is that a kind of rebreather of engine air outlet oil gas collecting device is provided.
For reaching this object, technical solution adopted in the utility model is: the outlet of resuscitation apparatus is provided with oil-gas condenser, oil-gas condenser and filtering core device and vacuum pump join successively, below oil-gas condenser, be provided with oil collecting case, the pipeline that resuscitation apparatus is exported to the each parts of vacuum pump inlet is sealing pipeline.
Rebreather of engine is discharged the moving waste gas with oil smog, first passes through the abundant condensation of oil-gas condenser, and the machine oil of condensation flows in oil collecting case, and oil collecting case communicates with engine sump tank, can return to crankcase by oil pump.Failing the oil vapor of abundant condensation enters filtering core device and carries out secondary filter, can make like this machine oil fully be reclaimed.Due to the increase of oil-gas condenser and filtering core device, certainly will cause the increase of engine exhaust resistance, so be provided with a small vacuum pump after filtering core device, by adjusting the degree of vacuum of vacuum pump, eliminate exhaust resistance.
The beneficial effect of feature of the present utility model and generation is: constructional device is simple, takes up room very little, does not substantially affect the layout of adjacent zeros parts.The machine oil of discharging is breathed in collection that can be comparatively complete, has reduced the pollution of oil gas to environment.
Brief description of the drawings
Shown in accompanying drawing be the utility model principle and structure diagram.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is further described.
Rebreather of engine air outlet oil gas collecting device, has resuscitation apparatus, oil-gas condenser, filtering core device, vacuum pump and oil collecting case etc.Its structure is: the outlet of resuscitation apparatus 1 is provided with oil-gas condenser 2, and oil-gas condenser and filtering core device 3 and vacuum pump 4 join successively, are provided with oil collecting case 5 below oil-gas condenser.The pipeline that resuscitation apparatus is exported to the each parts of vacuum pump inlet is sealing pipeline.
In order to detect the resistance of crankcase through resuscitation apparatus and oil-gas condenser final vacuum, between resuscitation apparatus and oil-gas condenser and between oil-gas condenser and filtering core device, be equipped with pressure transducer, this sensor and engine electronic control unit ECU join.The vacuum pressure value that ECU can adjust vacuum pump according to pressure reduction or Pressure Drop is to eliminate resistance.
