Description
The present invention is meant a kind of electric power system of motorcycle with electronic oil injection especially relevant for a kind of motorcycle with electronic oil injection.
See also Fig. 1, it is the schematic representation of traditional Carburetor engine, its fuel system mainly is that the air inflow by Carburetor 91 decides fuel delivery, promptly heal when big when the air inflow of pipeline 92, bigger from fuel tank 93 through the oil mass that oil pipe 94 is inhaled into Carburetor 91, this kind fuel system is entirely the mechanical type action, there are not sensor and controller to control fuel injection quantity, the firing circuit of its spark plug 95 is AC system capacitor discharge ignition system 96 (is called for short and exchanges CDI), and the power supply of interchange CDI is directly from generator, therefore when storage battery does not have electricity, still can start with foot-operated Starting mode.
The advantage of above-mentioned Carburetor engine is:
1, simple structure, with low cost.
When 2, storage battery does not have electricity, still can start in foot-operated mode.
Shortcoming is:
1, uncontrollable oil spout and igniting opportunity, comparatively oil consumption.
2, because of accurately not controlling fuel delivery, cause incomplete combustion, except oil consumption, and produce atmospheric pollution.
3, fuel oil is not that direct injection enters cylinder, and oil gas has remnants at pipeline 92 and accumulates, and also is to cause oil consumption and air-polluting reason.

The present invention mainly is when storage battery does not have electricity, and the side has given play to the function of electrical management, and it is described below in the running flow process of start-up course:
Please cooperate and consult Fig. 4 and Fig. 5, the 1st among the figure is first power supply circuits 21, and 2nd is second power supply circuits 22, and 3rd is the 3rd power supply circuits 23, and power management circuitry 2 control flows when pin is stepped on startup are as follows:
Step 51: when storage battery does not have electricity and during with foot-operated the startup fully, the electric power of generator 32 is through rectifier 33 power management circuitry 2 of flowing through.
Step 52: because first and second switching circuit 26,28 on second and third power supply circuits 22,23 all is not in closed condition before switching on, so the inevitable preferential flow of electric current is through first power supply circuits 21, that is the electric power of sensor 35, gasoline oil nozzle 36 (Injector) and the control relay 37 that supply engine control unit 34 (ECU), engine start are relevant.
Step 53: first comparison circuit 24 judges, when the power supply of first power supply circuits 21 is not satisfied as yet, and the electricity consumption of supplying first power supply circuits 21 fully.
Step 54: when the power supply of first power supply circuits 21 has been satisfied, instigate 26 one-tenth on-states of first switching circuit, begin to supply second power supply circuits 22, be i.e. the electric power of supply igniting crystal 38 (coil) and fuel pump 39 (fuel pump).
Step 55: first comparison circuit 24 judges, judges whether the power supply of first power supply circuits 21 is satisfied, and if not, then first switching circuit becomes the OFF state for 26 one-tenth, only supplies the electricity consumption of first power supply circuits 21, if then continue 22 electricity consumptions of supply second power supply circuits.
Step 56: second comparison circuit 27 is judged judge whether the power supply of second power supply circuits 22 is satisfied, if not, is then continued the electricity consumption of supply second power supply circuits 22.
Step 57: after first and second power supply circuits 21,22 all satisfied, engine promptly started smoothly, enters the engine running pattern.
Step 61: this moment first, second and third power supply circuits 21,22,23 equal normal power supplies, when using former car electrical load 40, as headlight, indicator, brake lamp and loudspeaker ... Deng.
Step 62: second comparison circuit 27 judges, judges whether the power supply of second power supply circuits 22 is not enough, if not, then keeps 23 power supplies of the 3rd power supply circuits, is in normal operation, and " RETURN " is one to enter step 63.
Step 63: make 28 one-tenth OFF of second switch circuit, the electric power of stop supplies the 3rd supply circuit 23.
Step 64: first comparison circuit 24 judges, judges whether the power supply of first power supply circuits 21 is not enough, if not, then keeps 23 power supplies of second power supply circuits, and " RETURN " is to enter step 65.
Step 65: 26 one-tenth OFF of first switching circuit, the electric power of stop supplies second supply circuit 22 provides first power supply circuits 21 to use all electric power, causes flame-out to avoid this ECU when machine.
Step 66: first comparison circuit 24 judges, judges whether the power supply of first power supply circuits 21 is satisfied, and if not, then maintains step 65, satisfies until 21 power supplies of first power supply circuits, if then enter step 67.
Step 67: make 26 one-tenth ON of first switching circuit, provide second power supply circuits 22, use and set up the required pressure of oil spout with first power supply circuits, 21 remaining electric power.
The above is not as can be known when storage battery has electricity, can reach electrical power distribution in certain sequence by power management circuitry 2, reach the function of electrical management, certainly when storage battery electric power is sufficient, electric current is through the judgement of the comparison circuit of power management circuitry 2, because of electric power plentifully so each power supply circuits normal power supply all, the situation that can not have power supply to hinder because of the setting of power management circuitry 2.
Compared with prior art, the present invention has following effect:
1, when storage battery does not have electricity fully, still can ride startup, with the required electric power of the complete priority of supply ECU of electric power, engine is started smoothly.
2, in engine running, the not excessive electricity consumption of the former car electrical load of reason and cause the ECU brownout and crash makes and cuts the engine.
3, the advantage that has motorcycle with electronic oil injection: decide the injection time of igniting opportunity and oil nozzle by the accurate control of ECU, so can reach fuel-efficient and oligosaprobic effect.
The foregoing description is the fuel pump of electronic type, but the motorcycle that adopts mechanical fuel pump is also arranged, and this moment, second power supply circuits promptly need not to provide the electric power of fuel pump.
In addition, adopt the firing mode that exchanges CDI if do not adopt the igniting crystal, because of the electric power that exchanges CDI directly from another coil groups of generator, so then need not to provide this electric power at second power supply circuits.
Moreover, if do not adopt the firing mode of lighting a fire crystal and adopting direct current CDI, then provide this electric power in these second power supply circuits.
Utilize system of the present invention, when motorcycle when storage battery does not have electricity fully, still can cooperate foot-operated startup of engine of motorcycle configuration itself, the electric power priority of supply engine that generator is produced when foot-operated is to guarantee smooth startup; And, can not cause the brownout of engine control unit to stop working because of the use of former car electrical load such as loudspeaker and lamp system (headlight, indicator, brake lamp) when driving.A synthetic unit makes the electronic component of whole system more simplify.
Please cooperate and consult Fig. 7, present embodiment is that power management circuitry 2 and rectifier 33 are combined into a unit, makes the electronic component of whole system more simplify.
Please cooperate and consult Fig. 8, present embodiment is that power management circuitry 2 and engine control unit 34 (ECU) are combined into a unit, makes the electronic component of whole system more simplify.
The specific embodiment that is proposed in the detailed description of preferred embodiment is not to be used to limit protection scope of the present invention only in order to be easy to illustrate technology contents of the present invention.
