As shown in Figure 5, the working procedure of control switch 8 is such, in the A-A cut-away view, when rotary spool 831, dextrorotation forwards the b point to by a point, cylinder head air outlet flue waste gas by connecting tube 5 is reduced to gradually closes, and at this moment mainly is by the new air of connecting tube 7 and the crankcase waste gas by connecting tube 6 on a small quantity; When rotary spool 831, left-handedly forward the d point to by the c point, the new air by connecting tube 7 is reduced to gradually closes, and at this moment mainly is by the cylinder head air outlet flue waste gas of connecting tube 5 and the crankcase waste gas by connecting tube 6 on a small quantity.The mixed proportion of gas can be determined according to the logical size of the mistake of a, b, but also the logical size of the mistake of root c, d is determined.
As shown in Figure 9, the working procedure of control valve 12 is such, in the A-A cut-away view, under state shown in Figure 9, the cavity of control valve 12 inside all is communicated with connecting tube 3 and 13, and a part of waste gas enters motor 100 after connecting tube 3 enters suction tude 4 or air-strainer 1; When rotary spool 1231, dextrorotation forwards the b point to by a point, and the cylinder head air outlet flue waste gas by connecting tube 3 is reduced to gradually closes; The big I of gas flow is determined according to the logical size of the mistake of a, b.
Need to prove that the profile of control switch 8 and control valve 12 is not limited only to the cylindrical drum shape, can determine its concrete shape according to spatial position and outward appearance and installation requirement; Simultaneously, the position of opening on it also can determine to adopt different direction and quantity according to actual needs.
In conjunction with Fig. 1, Fig. 2 as can be known, the working procedure of this environmental protection supercharged engine provided by the utility model is such: this motor is at first identical with traditional motorcycle engine, and the gas handling system air is inhaled into by empty filter 1, Carburetor 2, suction tude 3 in the firing chamber of motor and burns; Secondly, the waste gas that the waste gas of firing chamber discharge is discharged by pipeline 5 and casing is directed in the control switch 8 by pipeline 6, a part of fresh air please can be sucked in the control switch 8 by device 7 by filter simultaneously, control switch 8 can be controlled the ratio of the intake of waste gas and fresh air.Because the discharging of different motors is different with aeration quantity, therefore concrete optimal proportion scope point is different.If the amount of waste gas is 100% o'clock in the mixed gas, promptly the intake of fresh air is 0 o'clock, and its emission request can reach " Euro II " standard; If the amount of waste gas is 0 o'clock in the mixed gas, promptly the intake of fresh air is 100% o'clock, and the power of motor can increase by 10%～20%.When if the ratio of waste gas and fresh air changes between 0～100%, can take into account the requirement of discharging and power performance, as the CG125 motor, when waste gas accounted for 40%, power can improve 7%, and discharging reaches " Euro I " standard.The gas that sucks enters in the suction booster 10 by pipeline 9, and the gas by supercharging is entered in the control valve 12 by pipeline 11, and pressurization gas can pass through pipeline 3 then, and suction tude 4 enters the firing chamber of motor.Pressurization gas also can be by pipeline 3 from empty filter 1, Carburetor 2, and suction tude 4 enters the firing chamber of motor.When not needing supercharging as motor, then pressurization gas can pass through control valve 12, and pipeline 13 directly enters silencing apparatus and discharges.Suction booster 10 can be driven by the machine oil pump shaft, also can drive by the main driving gear on the bent axle, can also be by the clutch teeth wheel drive, thus suction booster 10 can be installed in the diverse location of right lid.The supercharging purpose of motor is exactly the aeration quantity that increases motor, thereby reach the output power that improves motor, at this moment pressurization gas is new air, the utility model can be according to the mass component of regulating pressurization gas, thereby reach the output power that improves motor, or the raising environmental protection, or improve the output power of motor and improve the purpose that environmental protection takes into account.
Casing flue gas leading 6 directly enters suction booster 10 by control switch, and gas of combustion enters control switch 8 by pipeline 5 and fresh air by filter cleaner 7.Control switch 8 is controlled the ratio that enters of gas of combustion and fresh air by rotary spool 83, thereby improves the exhaust emissions situation of motor.
Because the gas handling system air of traditional motorcycle engine is inhaled in the firing chamber of motor by empty filter 1, Carburetor 2, suction tude 3, directly be discharged in the atmosphere by silencing apparatus by the gas that burns.Environmental protection pressurization system provided by the utility model is then sent part waste gas and fresh air in the firing chamber back to after by supercharging again and is burnt, thereby reaches the purpose of purifying exhaust air.The density of air becomes big after the supercharging, thereby the air quality that enters engine chamber becomes big, has improved the charging efficiency of motor, raising engine power performance that can be bigger.
During this supercharged engine work, it can will send into suction booster 10 running superchargings combusted cylinder behind waste gas and two kinds of gas boostings of fresh air, also can adopt any one gas, by the control of control switch 8 realizations to gas componant.For example: when using waste gas fully, be equivalent to the secondary combustion of motor, be discharged to the CO in the waste gas body in the atmosphere, compounds such as CH can significantly reduce, thereby reduce discharge of harmful gases, reach the purpose of cleaning of off-gas discharging.This combustion manner can be used for extra high time of environmental requirement or place.When using fresh air fully, increase the aeration quantity of engines combustible gas, then can improve the power of motor.If two kinds of gases of waste gas and fresh air are the time spent all, is to take into account exhaust index and power performance.The adjusting of above-mentioned gas composition realizes by control switch 8.But this pressurization system may cause increasing of practical oil consumption when supercharging, if the user requires the power character of motor and environmental requirement when not high, can close pressurization system by control valve 12, and gas is directly discharged from baffler.
The ratio of waste gas and fresh air, mainly according to the user to the deciding of the requirement between environmental protection and the power, its ratio can be to regulate from 0 to 100%, optimal proportion is determined according to the concrete test data of various types.For example: the CG125 motor, when waste gas accounted for 40%, power can improve 7%, and discharging reaches " Euro I " standard.
Need to prove at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
