As shown in fig. 1, cylinder head, cylinder 34 inside are piston 37, and cylinder head is provided with suction tude 36, steam outlet pipe 35 and spark plug 38, the spark plug 38 other high-energy igniters 44 that are provided with.Be provided with Carburetor 40 and empty filter 39 mutually with suction tude.Be set side by side with secondary air compensating one-way valve 42 and performance tuner 41 in the middle of suction tude and the empty filter, be provided with exhaust gas recirculation valve 43 between secondary air compensating one-way valve and the performance tuner.All be connected between the above-mentioned parts by pipeline.
As shown in Figure 2, performance tuner 41 has a main body 11, and the main body bottom links to each other with the cylinder head suction tude.The bottom of main body 11 is provided with changing valve 15.Be arranged with changing valve Returnning spring 21 on the changing valve 15, perpendicular direction is provided with changing valve operating handle 18, and the changing valve operating handle is arranged on to be handled on the support 17.Main body 11 sidewalls are provided with exhaust gas recirculation interface 14 and tonifying Qi pipe nipple 13, and they are connected with empty filter with exhaust gas recirculation valve respectively; Be provided with rotary valve 3 in the main body 11, the rotary valve outer cover is provided with rotary valve Returnning spring 4, and internal sleeve is provided with adjustable lever 2, and is arranged with spring 1 on the adjustable lever 2.Also be provided with rotating shaft 9 and rotary shaft rack 7 on the rotary valve 3, operating handle 10 is arranged in the rotating shaft 9.
As shown in Figure 3, exhaust gas recirculation valve 43 comprises adapter 30, and adapter one side is provided with secondary air compensating pipe 28, joins with the secondary air compensating one-way valve; Adapter is provided with valve body 25, and body wall is provided with the waste gas air outlet and connects mouth 32, joins with the performance tuner; The bottom of valve body also is provided with release handle 27, is arranged with ring spring 26 on it.Be arranged with valve rod 24 in the valve body, be arranged with reset spring 23 on it, the upper end of valve body is provided with loam cake 22.
As shown in Figure 4, be arranged on the piston 37 in the cylinder, the periphery of its front end 6 slopes inwardly angled, forms the longitudinal cross-section of taper, and the narrow crack effect of bringing with the elimination traditional design reaches the discharging that therefore causes unburned carbon hydride.
The foam tube of Carburetor is provided with a plurality of foams hole, and quantity is 20～40, and its preferable range is 24～30, and it is evenly distributed to be divided into 6～10 rows.The aperture of main jet is 0.1～0.9mm on the Carburetor, and preferable range is 0.5～0.8mm.Reducing and the increase of foam hole number of main jet aperture can guarantee the mixed gas that atomization quality and ingredients are extremely excellent effectively.
Working principle of the present utility model:
Behind the engine start, for guaranteeing the idle stability of motor, the low discharging system of this moment has only traditional secondary air compensating one-way valve, utilizes negative exhaust pressure, replenishes air to relief opening, among a small circle carbon monoxide, hydrocarbon is being carried out the later stage oxidation.The performance tuner because of with throttle linkage, do not work, exhaust gas recirculation valve also can't provide exhaust gas recirculation because of closing of performance tuner.When throttle strengthens gradually, motor enters middle load condition (3000～5000 rev/mins) by idling, the performance tuner is because of opening with throttle linkage, a certain proportion of waste gas is under the high pressure effect, open exhaust gas recirculation valve and enter motor by the performance tuner, participate in combustion process, reduce amount of nitrogen oxides; Another strand fresh air enters motor from empty filter by the performance tuner, makes mixed gas further thinning, and balance causes the engine combustion cycle variation because of the ER EGR Rate fluctuation.Along with load strengthens, throttle strengthens (more than 5000 rev/mins), and for satisfying the engine power requirement, the performance tuner progressively turns down, and during throttle wide, the performance tuner cuts out fully; When motor when middle load～load greatly is excessive, the changing valve that navigability can tuner cuts out the performance tuner, makes motor break away from the lean-burn state, Carburetor recovers to provide rich mixture to motor at once, satisfies the power requirement.
