Abstract

PURPOSE: To enable the evaluation of control algorithm without making experimental tests with the use of an engine, a fuel injection pump and the like by simulating signals required for the control action of a fuel injection control.
CONSTITUTION: Circuiting means 1 and 4 generating starter torque signals and directing starting signals to an electronic control unit 5, and circuiting means 2, 9 and 10 directing signals for both of the quantity of fuel injection and the injection timing to the unit 5, are provided respectively. In addition, a circuiting means 3 converted both of the starter torque signal and the signal for the quantity of fuel injection into signals for engine angular velocity, and circuiting means 19 through 21 and 23 directing pulses to the unit 5, which are for angle of rotation synchronized with signals for revolving speed converted into signals for engine angular velocity, are also provided respectively. Furthermore, means 5 through 8, 11, 16 through 18, 22, 29 and 30 changing the transfer function of each circuiting means so as to be set, and setter means 25 through 27 directing sensor information signals including the position of an accelerator to the unit 5, are also provided respectively.
