Described stepper motor Carburetor plunger is made of stepper motor, plunger, stepper motor spindle nut and spindle screw mandrel, and the stepper motor end face has the locating rectangle groove, and the spindle screw mandrel is connected with the stepper motor spindle nut.
Described speed probe is made of digital cam trigger and trigger winding, and the digital cam trigger is to be welded on the magnetogenerator flywheel cylindrical by a heptangle projection dish to form.
Described shelves select sensor to be connected with the engine revolution axle is coaxial, and vacuum pressure sensor is communicated with intake manifold.
The design's principle is: during engine rotation, the magnetic pulse signal that digital cam trigger and trigger winding produce, shelves select sensor to arrive the signal of certain gear, vacuum pressure sensor detects the signal of intake manifold vacuum, the CPU that these signals are sent into ignition controler simultaneously handles, send the instruction of ignition advance angle after the processing and the spindle below the step motor type Carburetor plunger is done the mobile instruction of adjusting, obtain optimum igniting advance angle and optimal air-fuel ratio.
The advantage that this device had is:
1, set up shelves and selected sensor, velocity ratio that can detection of engine motorcycle under same speed conditions changes and the different ignition advance angles and the air fuel ratio of the required design of change in torque that takes place, makes it reach optimum.Make motorcycle in different road conditions, all have very strong adaptability as Plain, mountain area.
2, adopt step motor type Carburetor plunger, required air fuel ratio in the time of can be according to engine operation turns an angle step motor type Carburetor plunger by instruction, thereby adjusts the height of spindle, reaches the purpose of adjusting optimal air-fuel ratio.
3, the signal that sends of speed probe is a digital signal, can directly enter CPU, and structure is simpler, and signal is more accurate.
This device is used for motorcycle, can make motorcycle fuel consumption descend 15%, and moment of torsion increases by 20%, and it is more stable to burn, and exhaust emissions reaches standard.Because utilization is that the engine idle air fuel ratio is dense partially, the middling speed air fuel ratio is rare partially, the little dense design philosophy of high speed air fuel ratio, has guaranteed cold starting performance, Economy and the applicability of motorcycle.
