Embodiment
As shown in Figure 1, this clean fuel automobile nozzle emulsification comprises external socket 1, light emitting diode 8, current-limiting resistance 7, power resistor 9.It also comprises relay 6.Relay pack vinculum circle 5, movable contact 3, break contact 2 and normal opened contact 4.One end of the coil 5 of relay and socket 1. pin link to each other, the other end ground connection of coil, the movable contact 3 of relay and socket 4. pin link to each other, the two ends of power resistor 9 respectively with normal opened contact 4 and socket 1. pin link to each other, the break contact 2 of relay and socket 3. pin link to each other the 2. pin ground connection of socket.
When this clean fuel automobile nozzle emulsification and oil-gas shift switch and clean fuel controlling computer are used,, promptly switch air valve and open or close with oil-gas shift switch switching engine working state.When air valve is closed for working in the gasoline state, when air valve is opened for working in the clean fuel state.This clean fuel automobile nozzle emulsification 1. pin and air valve join, 3. pin and oil nozzle join, 4. the oil nozzle power end of pin and former car computer join.During in the gasoline state, air valve is closed in engine operation, the 1. no-voltage on the pin, and relay 6 is in releasing state.4. pin by movable contact 3 and break contact 2 with 3. pin be connected.Oil nozzle has electricity, proper functioning, and former car computer detects the oil nozzle proper functioning simultaneously, former car computer proper functioning, motor proper functioning.At oil-gas shift switch motor is switched to when working in the clean fuel state, when air valve was opened, 1. the obtained 12V voltage on the pin, relay 6 adhesives, and the 4. pin and 3. pin disconnection, oil nozzle quits work.Simultaneously, 4. pin by movable contact 3, normal opened contact 4, power resistor 9 with 1. pin be connected.Former car computer still can detect the oil nozzle operating current signal of a simulation, and former car computer proper functioning is started the function proper functioning.Light emitting diode is lighted simultaneously, and indication is in the clean fuel working state.
As shown in Figure 2, the two ends of the power resistor 9 of this clean fuel automobile nozzle emulsification also can be respectively with normal opened contact 4 and socket 3. pin link to each other.Adopt this structure, when converting the clean fuel working state to, petrol jet and power resistor 9 are in series.Because the resistance of the resistance value ratio oil nozzle of power resistor is many greatly, oil nozzle is not worked because of driving voltage is too little, but circuit still keeps conducting, and former car computer still can detect the oil nozzle working signal, and former car computer proper functioning is started the function proper functioning.The power resistor of this clean fuel automobile nozzle emulsification becomes cascaded structure with oil nozzle, is called the series type emulsification.Shown in Figure 1 for and connect the formula emulsification
