Description
Technical field
The utility model relates to engine art, particularly a kind of gas and oil separating plant of motorcycle engine.
Background technique
Because running up, engine interior can produce the internal pressure and the barometric pressure imbalance of motor, will cause motor in-fighting loss when burning outburst acting bigger than normal like this, for solving this contradiction, on the crankcase of motor or cylinder head cover, open an air balance pipe usually.But because crankcase produces is fuel-air mixture, need one can be to the structure of oil gas normal separation, generally all adopt at present labyrinth structure to be set machine oil is precipitated, get back in the crankcase of motor, gas and ambient atmosphere normally exchange.But because the stroke that labyrinth structure refluxes machine oil is longer, isolated machine oil tends to the motor fuel injection event occur with the ejection of motor chamber pressure.
Summary of the invention
The purpose of this utility model provides a kind of gas and oil separating plant of motorcycle engine, and it can solve the motor fuel injection event effectively.
The purpose of this utility model is achieved in that and comprises cylinder-head cover, deaerator.Described deaerator is external to be fixedly connected on the cylinder-head cover, and the cylinder-head cover end that links to each other with deaerator is provided with that mixed gas portals and spill port in the mating face; Described deaerator is connected to form by body that is provided with die cavity and the lid that is provided with gas discharge hole, be provided with a partition in the die cavity of body, this partition is divided into the disengagement chamber that two parts communicate to die cavity, the mixed gas of the corresponding cylinder-head cover of one of them disengagement chamber portals, and another disengagement chamber is communicated with lid by through hole.
The aperture that the mixed gas of cylinder-head cover portals is provided with flange.
Partition and body in the die cavity of deaerator body are overall shaped into one, and this partition is a curved shape, and die cavity is divided into two disengagement chambers up and down, and two disengagement chambers are communicated with mouth between the cavity lateral by partition.
Be provided with grade wall in the disengagement chamber over against the through hole aperture.
Be provided with circular groove in the mating face of deaerator body and lid, this circular groove is communicated with disengagement chamber by through hole.
The deaerator lid is provided with die cavity, and this die cavity wall is provided with gas discharge hole.
Owing to adopted such scheme, described deaerator is external to be fixedly connected on the cylinder-head cover, the cylinder-head cover end that links to each other with deaerator is provided with that mixed gas portals and spill port in the mating face, deaerator is connected to form by body that is provided with die cavity and the lid that is provided with gas discharge hole, the mixed gas that is mixed with the machine oil molecule of thermal expansion portals from the mixed gas of cylinder-head cover and sprays in the die cavity of deaerator in the engine case, machine oil molecule in the mixed gas condenses into elaioleucite and flows back in the engine case from spill port in die cavity, discharge from the gas discharge hole of deaerator with the gas of machine oil molecular separation.Be provided with a curved shape partition in the die cavity of described body, this partition is divided into two disengagement chambers up and down to die cavity, two disengagement chambers are by mouthful being communicated with between partition and the cavity lateral, and the mixed gas of one of them disengagement chamber correspondence cylinder-head cover portals, and another disengagement chamber is communicated with lid by through hole.Because the mixed gas of a corresponding cylinder-head cover of disengagement chamber portals, the interior fuel-air mixture body of motor portals from the cylinder-head cover mixed gas because of pressure difference and directly is sprayed onto this disengagement chamber, because the energy loss of fuel-air mixture body, after condensing, part machine oil molecule in the fuel-air mixture body is attached to the disengagement chamber inwall, and flow to the bottom of die cavity along the disengagement chamber inwall, form first Oil-gas Separation; The energy further loss of mixed gas after the mixed gas after first the separation upwards enters another disengagement chamber, the machine oil molecule condense the back because of proportion greater than gas, sink down into the die cavity bottom along the disengagement chamber inwall, gas then enters the lid of deaerator from through hole, forms the secondary Oil-gas Separation.Be provided with circular groove in the mating face because of deaerator body and lid, this circular groove is communicated with disengagement chamber by through hole, the deaerator lid is provided with die cavity, this die cavity wall is provided with gas discharge hole, the gas via through holes enters energy further loss behind the lid die cavity, is attached to die cavity and circular groove after remaining machine oil molecule condenses, and forms Oil-gas Separation once more, the gas discharge hole of gas after Oil-gas Separation from lid is discharged into the atmosphere, realizes pressure balance.Owing to be provided with grade wall over against the through hole aperture in the disengagement chamber, gas is obstructed when entering through hole, through in the chamber, entering through hole again after the circulation, prolonged the holdup time of gas in disengagement chamber, it can be separated fully.Isolated machine oil flows back to engine case by the spill port on its hilllock skull at last and is used to lubricate.
The utility model is simple in structure, has saved the labyrinth structure in original separator, and mould is easy to manufacture, has reduced fabricating cost.It utilizes gas energy loss principle and oil gas difference of specific gravity, realizes separating of gas and elaioleucite, and simple because of the die cavity inner structure simultaneously, isolated machine oil refluxes fast, has solved the phenomenon of motor oil spout.And need not take apart the engine and just can keep in repair.
The utility model is described in further detail below in conjunction with drawings and Examples.
