Abstract
The utility model discloses an engine rocker arm chamber cover with an oil-gas pre-separation chamber. The structure of the engine rocker arm chamber cover with the oil-gas pre-separation chamber includes that a cover board assembly is composed of two stand plates and an oil returning pipe. A baffle is installed inside a rocker arm cover body and is arranged between the two stand plates of the cover board assembly. The cover plate assembly combining with the rocker arm cover body in a sealing mode forms three oil gas separation chambers through a bolt. The height between the left end stand plate of the two stand plates and the top face inside the rocker arm cover body is 15 millimeters. The height between the right end stand plate of the two stand plates and the top face inside the rocker arm cover body is 13.6 millimeters. The height of a gap between the baffle and the bottom face of the cover board assembly is 9 millimeters. The engine rocker arm chamber cover with the oil-gas pre-separation chamber resolves the problem that the difficulty of arrangement is increased caused by the reason that the size of a breathing device is large. At the same time, three-level oil-gas separation prevents the breathing device from dripping oil. Therefore, the engine rocker arm chamber cover with the oil-gas pre-separation chamber not only can seal rocker arm working space, but also is simple in structure, saving in peripheral space of the engine, and good in oil-gas separation effect.
Description
Technical field
The invention belongs to engine component, be specifically related to a kind of engine rocker chamber cover with oil-gas pre-separation device.
Background technique
Along with the fast development of automobile industry, country is also more and more higher to the requirement of vehicle economy to exhaust index and the user of motor.In service in engine operation, crankcase contains the steam of machine oil and must discharge, and this just requires must filter oil gas.It generally is to be undertaken by resuscitation apparatus that hydrocarbon filter separates, if but resuscitation apparatus is when only being provided with single filter, to there be following two problems: the one, the volume ratio of resuscitation apparatus is large (in order to strengthen filter capacity), increased thus the layout difficulty of resuscitation apparatus on motor; The 2nd, ubiquity resuscitation apparatus oil dripping problem when limited conditions.For addressing this problem, the present invention proposes and a kind of oil gas is carried out first the one-level pre-separation, most of oil gas was filtered before entering resuscitation apparatus in advance, and then carry out the last separating treatment of oil gas by resuscitation apparatus.
Summary of the invention
The purpose of this utility model is, proposes a kind of engine rocker chamber cover with oil gas pre-separation chamber, by increasing oil-gas pre-separation device in rocker arm chamber cover, thereby reaches the volume that reduces resuscitation apparatus, the purpose that reduces oil consumption and environmental protection.
Below in conjunction with accompanying drawing know-why of the present utility model and structure are described.
Engine rocker chamber cover with oil gas pre-separation chamber mainly comprises rocker arm bonnet body and cover plate assembly, its structure is that cover plate assembly is made of two risers and an oil return bend pipe, in the rocker arm bonnet body, be provided with baffle plate, baffle plate places the centre of two risers of cover plate assembly, and cover plate assembly is combined to form 3 Oil-gas Separation chambers by bolt and the sealing of rocker arm chamber cover body.After oil gas entered each grade separation chamber, according to the adsorption principle, the tiny oil droplets in the mixed gas can adhere to the internal surface of separation chamber, then is back to cover plate along the surface under Action of Gravity Field, and is inner from oil return bend pipe return engine, realizes Oil-gas Separation.
The beneficial effect of characteristics of the present utility model and generation is, adopt a cover plate assembly in rocker arm bonnet, to form 3 Oil-gas Separation chambers, having eliminated because the resuscitation apparatus volume is larger increases the difficulty problem of arranging, three grades of Oil-gas Separation can not make resuscitation apparatus produce the oil dripping phenomenon simultaneously.Not only can satisfy the sealing of rocking arm working space, and simple in structure, saving motor peripheral space, the oil gas pre-separation is effective.
Description of drawings
Fig. 1 is the utility model structural representation sketch.
Fig. 2 is the utility model internal structure and working principle schematic representation.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment structural principle of the present utility model is described further.With the engine rocker chamber cover of oil gas pre-separation chamber, its structure is that cover plate assembly 1 is made of two risers 2 and an oil return bend pipe 3.Be provided with baffle plate 5 in rocker arm bonnet body 4, baffle plate places the centre of two risers of cover plate assembly, and cover plate assembly is combined to form 3 Oil-gas Separation chambers (such as Fig. 1) by bolt 6 and the sealing of rocker arm chamber cover body.Left end riser in two risers and the height of rocker arm bonnet body inner top surface are 15mm; The height of right-hand member riser and rocker arm bonnet body inner top surface is 13.6mm; The clearance height of baffle plate and cover plate assembly bottom surface is 9mm(such as Fig. 2).Oil gas is separated most of oil gas by arrow shown in Figure 2, and the diameter of oil return bend pipe is 6mm.
Thereby the baffle plate in the rocker arm chamber cover places the centre of two risers of cover plate assembly to form 3 Oil-gas Separation chambers.Oil gas in the rocker arm chamber cover is first by the gap of cover plate assembly and rocker arm chamber disengagement chamber, and for the first time Oil-gas Separation is done in first Oil-gas Separation chamber that enters left end riser and rocker arm bonnet baffle plate formation; Then carry out second level Oil-gas Separation in second the Oil-gas Separation chamber that consists of by rocker arm bonnet baffle plate and right-hand member riser; Then carrying out for the third time Oil-gas Separation by the gap of right-hand member riser and rocker arm chamber disengagement chamber, enter at last resuscitation apparatus.Oil gas carried out three pre-separations altogether before entering resuscitation apparatus like this, had effectively prevented resuscitation apparatus oil dripping problem.
Cover plate assembly is bolted on the rocker arm chamber cover body by 3, then assembly is installed on the motor, is provided with sealing gasket between cover plate assembly and rocker arm chamber cover body.
