Abstract
The utility model discloses an oil-gas separator of an automobile engine, which comprises a gas inlet, a main body part, a gas outlet and the like. A rotor is arranged in the main body part. With the structure in the technical scheme, the utility model can effectively solve the technical problems of the cyclone type or filter core type oil-gas separator in the prior art, such as poor separation effect, high pressure loss and incapability of satisfying European V and European VI emission standards. The oil-gas separator is a centrifugal oil-gas separator driven by engine oil, and the oil in the oil-gas mixture can be effectively separated in accordance with the principle of centrifugal force, thereby improving the separation efficiency and satisfying the continuously enhanced regulatory requirements. Moreover, the utility model has the advantages of high separation efficiency, lower pressure loss, high reliability, convenient layout and the like, can satisfy the European V and European VI emission requirements, and can reduce the consumption of the engine oil.
Description
Technical field
The utility model relates to a kind of motor car engine deaerator.
Background technique
At present, the deaerator in most of crankcase ventilation systems adopts vortex type or filer element type, and the advantage of cyclone type oil-gas separator is a low price, and arrangement convenience, shortcoming are that separation effect is low, and the pressure loss is big; The advantage of filer element type deaerator is that separation effect is higher, arranges more conveniently, and shortcoming is that the pressure loss is bigger, and filter core needs regularly to change.But more and more stricter along with rules, more than two class deaerators can't satisfy Europe V, Europe VI emission request fully.
The model utility content
Technical problem to be solved in the utility model is, vortex type of the prior art or filer element type deaerator, exist inferior separating effect, the pressure loss big, and can't satisfy technical problems such as Europe V, Europe VI emission standard, and a kind of motor car engine deaerator is provided.
Technological scheme provided by the utility model is, a kind of motor car engine deaerator comprises that described deaerator comprises suction port, main body and air outlet etc., and described main body inside is provided with rotor.
Described suction port is located at the top of described main body, and described air outlet is arranged on the sidepiece of described main body.
The bottom of described main body is provided with the driving machine oil duct, is provided with high-pressure oil in the described driving machine oil duct, and described high-pressure oil drives described rotor rotation.
Be provided with back oil road at described rotor and driving machine oil duct bottom.
Described rotor is the centrifugal rotor structure.
Adopt technological scheme provided by the utility model, can effectively solve vortex type of the prior art or filer element type deaerator, exist inferior separating effect, the pressure loss big, and can't satisfy technical problems such as Europe V, Europe VI emission standard; Deaerator provided by the utility model is the centrifugal oil-air separator that machine oil drives, utilize the principle of centrifugal force that the oil in the fuel-air mixture is effectively separated, improve separation effect, satisfy constantly strict laws and regulations requirement, have advantages such as separation effect height, the pressure loss is low, reliability is high, layout is more convenient, Europe V, Europe VI emission request can be satisfied, oil consumption can be reduced.
Description of drawings
In conjunction with the accompanying drawings, the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Wherein, 1 is suction port; 2 is rotor; 3 is the air outlet; 4 is the driving machine oil duct; 5 back oil roads;
Embodiment
As shown in Figure 1, technological scheme provided by the utility model is, a kind of motor car engine deaerator comprises that described deaerator comprises suction port 1, main body and air outlet 3 etc., and described main body inside is provided with rotor 2; Described suction port 1 is located at the top of described main body, and described air outlet 3 is arranged on the sidepiece of described main body; The bottom of described main body is provided with driving machine oil duct 4, is provided with high-pressure oil in the described driving machine oil duct 4, and described high-pressure oil drives described rotor 2 and rotates; Be provided with back oil road 5 at described rotor 2 and driving machine oil duct 4 bottoms; Described rotor 2 is centrifugal rotor 2 structures.
The oil duct that machine oil in the motor main oil gallery communicates with main oil gallery by deaerator enters deaerator inside, and this machine oil drives rotor 2 runnings of deaerator inside.The mixed gas of discharging from crankcase enters by deaerator suction port 1, the rotor 2 of deaerator high speed rotating under the effect of high-pressure oil, under the centrifugal action of rotor 2, oil particles in the mixed gas is thrown on the separator inwall, be back in the crankcase by drainback passage along inwall, isolated clean gas enters gas handling system from deaerator air outlet 3.
The oil duct that machine oil in the motor main oil gallery communicates with main oil gallery by deaerator enters deaerator inside, and this engine oil pressure is higher, can drive rotor 2 runnings of deaerator inside.The mixed oil and gas of discharging from crankcase enters by deaerator suction port 1, under the centrifugal action of rotor 2, oil particles in the mixed gas is thrown on the deaerator inwall, this inwall also plays condensation, the oil particles that condensation is got off is back in the crankcase by drainback passage along inwall, and isolated clean gas 3 enters gas handling system from the air outlet.Like this, the gas of relative clean carries out secondary combustion, discharges low.
