1. an automobile gasoline mixes using method with alcohols, comprises gas supply and injection and alcohols supply and injection and master controller, it is characterized in that:

  • establishing the engine speed idling is V 0, corresponding gasoline fuel injection quantity is Q 0, V 0'"'"'=V 0+ Δ

    V 0, V 0'"'"' time corresponding gasoline fuel injection quantity be Q 0'"'"', Q 0With Q 0'"'"' be to represent fuel injection quantity/unit time, the present engine rotating speed is V 1, Δ

    V 0

    V 0Concrete grammar is as follows;

    1) begins to start detection of engine rotating speed, present engine rotating speed V 1

    V 0+ Δ

    V 0The time, with the oil spout control data control petrol jet oil spout of master controller output, and close the alcohols nozzle;

    2) as engine speed V 1

    V 0+ Δ

    V 0The time;

    A, locking petrol jet output quantity keep fuel injection quantity at Q 0

    Q 0'"'"' between any value invariable, disconnect the guide line of master controller and petrol jet;

    B, simultaneously the guide line of the petrol jet of alcohols nozzle and master controller is connected, be used for controlling the alcohols nozzle ejection with the control data of master controller;

    C, when the alcohols nozzle can'"'"'t spray Aalcohols fuel, the petrol jet guide line of master controller is connected the petrol jet drive circuit, recover the control of master controller to petrol jet;

    3) if the present engine rotating speed changes V 1

    V 0+ Δ

    V 0The time, stop the injection of alcohols nozzle, by main controller controls petrol jet injected petrol;

    4) as above-mentioned process circulation.
