Research Foundation and Technical Route2.1. Design of Fuel Injection Control ProcessAccording to the speed signal, ECU adopts starting fuel injection control or after-starting fuel injection control. Fig.1 shows the spray quantity control process. When the speed is less than 300 r/min, ECU chooses starting fuel injection control. The amount of fuel injection is determined by the basic fuel injection scale stored in the ECU and coolant temperature combined with linear interpolation method, and then the power supply voltage correction is added to gain the starting fuel injection quantity. When the speed is more than 300 r/min, ECU chooses after-starting fuel injection control. Determine the basic injection quantity first, if the throttle opening is 40-70, that is, the throttle position sensor signal within the scope of 2.1 to 3.3 V, then add the correction of closed-loop control of oxygen sensor, coolant temperature correction and power supply voltage correction to gain the start of the fuel injection quantity, otherwise directly join the coolant temperature correction and power supply voltage correction.2.2. Technical RouteGT-POWER sets up the engine model of LJ465Q, and gets the basic fuel injection scale by simulation calculating for starting fuel injection control.The control model of starting and after-starting are built by MotoHawk, and the starting fuel injection control is in look-up table method of open-loop control. Trained BP neural network algorithm are used to get the basic fuel injection quantity first in after-starting fuel injection control, and the fuzzy PID control algorithm of oxygen sensor closed-loop control are added to correct the basic fuel injection volume when the throttle opening is 40 -70 , and the other throttle opening is in open-loop control 4.Figure 1.
