[embodiment]
Below in conjunction with accompanying drawing structure of the present utility model is further detailed.
As shown in Figure 1: the utility model mechanical structure is made of stepper motor 1, support 2, corner block 3, rotating shaft 4, Returnning spring 5, pushing block 6, special-purpose nut 7.
Wherein, rotating shaft 4 is positioned at first bight of corner block 3, and second bight 32 comprises the ccontaining pushing block 6 of a platform thereon, and third angle portion contacts with progressive motor 1.Described special-purpose nut 7 is screwed into this spiro pluging hole and part support 2 is fixed on pump end (can utilize the pump housing to have screw).
Its working principle: when motor during in pure diesel oil mode of operation, 1 of stepper motor is retracted in initial position under the system electric-controlled unit command control.Pushing block 6 spring 5 that is reset is pushed into its outer dead point (accompanying drawing upper/lower positions), i.e. push rod 6 pushing corner block 3 under Returnning spring 5 promotes, the position that its third angle portion and stepper motor 1 axial end are adjacent to.Injection Pump adjustable lever 8 is controlled by the Injection Pump speed-regulating handle only.The Injection Pump characteristic of fuel delivery does not have change.
When motor converted the double fuel mode of operation to, system electric-controlled unit detected engine speed, if rotating speed is supplied with the substitute fuel rotating speed less than setting, stepper motor is awaited orders, and motor is still used pure diesel oil work.When rotating speed reaches setting supply substitute fuel rotating speed, the shaft extension of ECU (Electrical Control Unit) control step motor 1 goes out, promote corner block 3, second bight pushing pushing block, 6 compression reseting springs 5, simultaneously with Injection Pump adjustable lever pushing tow to desired location, the Injection Pump fuel injection quantity also reduces to setting value (engine speed increases, and the Injection Pump fuel injection quantity is constant).Meanwhile, ECU (Electrical Control Unit) control substitute fuel injection apparatus is pressed set amount injection substitute fuel to suction tude.
