Description
Technical field
The utility model relates to a kind of air that is used in and leaves the purification plant that crankcase purified air in the past, relates in particular to a kind of gas and oil separating plant of supercharged engine.
Background technique
When motor is started working, can produce piston air leakage, piston air leakage is mixed to form gas mixture with the machine oil particle in movement process, and this gas mixture is called the reason of pollution of atmosphere, therefore need to make it return to firing chamber so that its burning.Existing means are to be connected gas and oil separating plant is set between crankcase and gas handling system, so that gas mixture is processed, realize Oil-gas Separation.
In existing Oil-gas Separation process, the power source that orders about the motion of air-fuel mixture deposits yields is mainly derived from intake manifold and air filter final vacuum degree, for the supercharging type, under small load condition, the degree of vacuum of intake manifold plays a major role, under high load working condition, air filter final vacuum degree plays a major role, during natural aspiration, the degree of vacuum of engine intake manifold plays a major role, therefore, when crankcase ventilation system is set, need to consider the impact of two vacuum sources on crankcase pressure and oil-gas separation efficiency.And gas mixture is carried out in the gas and oil separating plant structure of Oil-gas Separation processing, the existing gas and oil separating plant be applied on the pressure-increasing machine h type engine h, mainly by two chambeies, formed, one is connected with intake manifold, a pressure controlled valve of controlling crankcase pressure is installed in the middle of the pipeline connected, Oil-gas Separation is not carried out under working state at pressurized machine in this chamber; Its two with air filter after be connected, connecting pipeline is middle without pressure controlled valve, the pressure of crankcase is mainly regulated mutually by the pressure after air filter and the crushing between gas and oil separating plant, meets the demands to guarantee crankcase pressure, and Oil-gas Separation is carried out in this chamber under the pressurized machine working state.
In addition, in existing gas and oil separating plant, also has a kind of cyclone type oil-gas separator, it is mainly that tangent direction by suction port and deaerator housing (cylindrical) enters in gas and oil separating plant, or gas and oil separating plant is directly done to curl, realize rotatablely moving of gas mixture, to reach the effect of Oil-gas Separation, but the speed of the operation of the gas mixture in this scheme is lower, the centrifugal force that the machine oil particle produces is little, and short grained machine oil molecule is difficult for separating.
The model utility content
For solving the deficiencies in the prior art, the degree of vacuum after the utility model provides a kind of reduction to intake manifold, air filter is that require, gas and oil separating plant that can effectively improve the supercharged engine of oil-gas separation efficiency.
For achieving the above object, the gas and oil separating plant of supercharged engine of the present utility model, it is from isolating machine oil by crankcase in the gas mixture of gas handling system guiding, and it has:
Shell separator, be fixedly installed with respect to camshaft, has suction port in its side near the end of camshaft, at its opposite side, has relief opening, and be provided with return opening on its bottom surface;
Rotating separation device, be arranged on the end of camshaft, and the end with camshaft is arranged in shell separator, described rotating separation device has in company with the camshaft rotation orders about the structure that the gas mixture in shell separator is flowed to relief opening by suction port.
As the improvement to technical solutions of the utility model, described return opening is arranged on the bottom surface away from the shell separator of the end of camshaft.
As the restriction to technical solutions of the utility model, described rotating separation device is impeller.
As the restriction to technical solutions of the utility model, also comprise the pressure control device that the pressure in shell separator is controlled.
As the further restriction to aforesaid way, described pressure control device is pressure controlled valve.
Adopt as above technological scheme, the rotating separation device that rotarily drives by camshaft rotates, this rotation provides a centrifugal force for the gas mixture entered in separator, gas mixture in shell separator is flowed to relief opening by suction port, when the gas mixture outside guaranteeing shell separator constantly enters into shell separator inside by suction port, enter into the interior gas mixture of shell separator under the effect of centrifugal force, with rotating separation device, the inwall of shell separator produces collision, gas is discharged by relief opening, oil droplet is attached on rotating separation device surface and shell separator inwall, when forming large oil droplet, oil droplet is flowed out by return opening, it has effectively realized the processing to gas mixture, reduced intake manifold, degree of vacuum requirement after air filter.
In addition, the rotating speed of rotating separation device is determined by the rotating speed of camshaft, the centrifugal force size of its generation is variable, namely when Engine torque and rotating speed were low, piston air leakage was little, and the diameter of the machine oil particle that blow-by of piston carries is larger, the large less centrifugal force of machine oil particle needs just can be from separating gas mixture, now, because the rotating speed of the rotating separation device of camshaft driven rotary is little, effectively met the separation demand under this state; When motor is in the operating mode of large rotating speed, large load; piston air leakage is large and machine oil grain amount that carry is large; granule machine oil molecular amounts is many; the large centrifugal force of these little machine oil particles needs could be from separating gas mixture; now; because the rotating speed of camshaft driven rotary segregating unit is larger, met the centrifugal force demand of Oil-gas Separation under this state.Therefore, adopt the technical solution of the utility model, can effectively improve oil gas separation.
In sum, adopt the technical solution of the utility model, reduced in manufacture process to the degree of vacuum requirement after intake manifold, air filter, and improved oil gas separation.
