From the return gas channel 141 being connected with motor intake manifold 14 is additionally provided on device 22, first is provided on return gas channel 141
Control valve 41.After the crankcase of cylinder body 11 generates gas blowby and enters gs-oil separator 20, the gas scurried out by crude separation and
Essence separation, the machine oil after separation flow into oil sump 13 from drainback passage 131, and the gas after separation is flowed into from return gas channel 141
In inlet manifold 14, to complete the circulation of Oil-gas Separation and machine oil and gas in gas blowby, the first control valve 41 can be prevented
Gas backflow in inlet manifold 14 enters in gs-oil separator 20.
Further, the present embodiment further includes air cleaner 51, compressor 52 and first gas passage 31, air filter
Clear device 51 and compressor 52 pass sequentially through first gas passage 31 and are connected with inlet manifold 14, and outside air is by air cleaner 51
Into first gas passage 31, inlet manifold 14 is entered under the action of compressor 52.In order to when engine just starts to hair
Motivation carries out tonifying Qi, and crankcase ventilation system provided in this embodiment further includes second gas channel 32, second gas channel 32
One end be connected to first gas passage 31, communicating position is set between compressor 52 and inlet manifold 14, the other end with
Oil sump 13 is connected, and the gas in first gas passage 31 can be that engine carries out tonifying Qi by second gas channel 32.?
In above-mentioned setting, by changing the communicating position in second gas channel 32 and first gas passage 31, make second gas channel 32
The position being connected to first gas passage 31 is set between compressor 52 and inlet manifold 14, and air passes through the increasing of compressor 52
Can just it enter in engine after pressure and heating, this makes the hair of machine oil generation emulsion after capable of preventing cold air from entering engine
It is raw.In order to control the air flowing in second gas channel 32, the second control is additionally provided in second gas channel 32
Valve 42 processed, the second control valve 42 prevent air from blowing back into first gas passage 31 out of engine.
In the present embodiment, crankcase ventilation system further includes third gas channel 33, and third gas channel 33 is connected to
Between gs-oil separator 20 and first gas passage 31, third control valve 43, third are additionally provided on third gas channel 33
The setting of control valve 43 can prevent air from blowed back into gs-oil separator 20 out of first gas passage 31.
In order to more accurately control the air-flow in each gas passage, in the present embodiment, the first control valve 41,
Two control valves 42 and third control valve 43 all can be solenoid valve, the first control valve 41, the second control valve 42 and third control valve
43 can be by the control of ECU (Electronic Control Unit).Compared to mechanical valve body, solenoid valve is in extreme ring
Work under border is more stable.This avoids refrigeration air enters the phenomenon in engine due to the failure of each valve body.
Further, in the present embodiment, crankcase ventilation system further includes the 4th gas passage 44, logical in the 4th gas
Turbine 53 and catalyst converter 54 are provided on road 44, the exhaust gas that engine is generated is discharged.
Further, in the present embodiment, crankcase ventilation system further includes filler cap 61, the first filling passage 62 and
Second filling passage 63, the first filling passage 62 and the second filling passage 63 are connected with filler cap 61, and first, which refuels, leads to
The one end of road 62 far from filler cap 61 is connected with the cylinder cap 12 of engine, and the second filling passage 63 is far from filler cap 61
One end be connected with gs-oil separator 20, the machine oil filled from filler cap 61 can by the first filling passage 62 and second plus
Oily channel 63 enters in engine.In filling engine oil excessive velocities, the first filling passage 62 may generate sealing gland phenomenon, resistance
The only entrance of machine oil, at this point, machine oil still can be by the second filling passage 63, via gs-oil separator 20 and drainback passage
131 enter in oil sump 13.
Fig. 3 is crankcase ventilation system shown in Fig. 2 in engine low load operating condition, the schematic diagram of gas flowing, and Fig. 4 is
Crankcase ventilation system shown in Fig. 2 is in high engine load operating condition, the schematic diagram of gas flowing.As shown in Figures 2 to 4, exist
When engine just starts (as shown in Figure 2), the piston air leakage of engine is few, and the air pressure in oil sump 13 is very low, at this point,
Air pressure in oil sump 13 is less than the air pressure in inlet manifold 14, and the air pressure in inlet manifold 14 is less than again in air cleaner 51
Air pressure, engine interior is not in gas-blowing phenomenon, and the second control valve 42 is opened, and fresh air is by the pressurization of compressor 52
And can be entered in oil sump 13 by second gas channel 32 after heating, it is 13 tonifying Qi of oil sump.
With continuing to run for engine, the pressure in oil sump 13 increases rapidly, at this point, oil sump 13, inlet manifold
14 and the size of the air pressure in air cleaner 51 change, the air pressure in inlet manifold 14 is less than the gas in oil sump 13
It presses, the air pressure in oil sump 13 is less than the air pressure in air cleaner 51.At this point, engine is in running on the lower load, such as Fig. 3 institute
Show, gas blowby occurs for the crankcase of cylinder body 11, and the first control valve 41 is opened, and the second control valve 42 is closed, and the gas scurried out is by oil
After gas separating device 20, the machine oil isolated is returned in oil sump 13 by drainback passage 131, and the gas isolated is logical by return-air
Road 141 continues to participate in engine acting into inlet manifold 14.
As the load of engine is continuously increased, engine is in high load capacity operating condition, as shown in figure 4, at this point, compressor 52
Efficient operation, the air pressure in inlet manifold 14 is increased rapidly, and air leak amount is also continuously increased, at this point, the air pressure in oil sump 13
Less than the air pressure in air cleaner 51, the air pressure in air cleaner 51 is less than the air pressure in inlet manifold 14, the first control
Valve 41 is closed and the second control valve 42 is in closed state, and to prevent the reflux of gas, third control valve 43 is opened, due to
52 high-efficiency operation of compressor at this time, there are biggish vacuum degrees between air cleaner 51 and compressor 52, by Oil-gas Separation
Gas after device 20 separates enters in first gas passage 31 by third gas channel 33, participates in the acting of engine again.
It is further to note that by this present embodiment, compared with the prior art, position transfer of the gs-oil separator 20 from cylinder cap 12
The position of cylinder body 11 is arrived, cylinder cap 12 is not connected to directly with gs-oil separator 20, and the oil leak hole inside cylinder cap 12 has oil
When gas gaseous mixture, since the air pressure of cylinder cap 12 at this time is greater than the air pressure in oil sump 13, the fuel-air mixture in cylinder cap 12 can
Entered in gs-oil separator 20 by the channel that the first filling passage 62 and the second filling passage 63 are formed, gs-oil separator 20 will
After air-fuel mixture gas is separated, gas, which can reenter in first gas passage 31, participates in engine acting.
As shown in figure 5, by filler cap 61 and can be filled in filling engine oil, if machine oil fills speed mistake
When fast, machine oil can by the first filling passage 62 enter cylinder cap 12, and by the second filling passage 63, gs-oil separator 20 and
Drainback passage 131 enters in oil sump 13, can more rapidly carry out the filling of machine oil, and be no longer influenced by the filling of machine oil
The influence of gas.
In conclusion the utility model is by the way that gs-oil separator 20 to be set on cylinder body 11, compared to by Oil-gas Separation
Device 20 is set to the prior art on cylinder cap 12, the installation site of gs-oil separator 20 can be made to be arranged more on the lower, this just exists
Contact of the gs-oil separator 20 with cool ambient air is largely avoided, the production of 20 inside droplet of gs-oil separator is reduced
It is raw, reduce the generation of lubricating oil emulsion phenomenon and oil dilution phenomenon.
