摘要： PURPOSE:To prevent the abnormal action of a fuel injection quantity regulating member, and to prevent the hunting of an engine, by correcting at least one of the integral, proportional, and differential constants in a feedback system in correspondence to the width of change in the position of the regulating member, and further by maintaining it for a prescribed time. CONSTITUTION:A microcomputer 1 calculates the optimum injection quantity of fuel on the basis of the signals from various sensors which detect the operating conditions of an engine, and sends a command value to a servo amplifier 3 via a D/A converter 2. Then, the servo amplifier 3 drives a linear solenoid 5, so that the error in the actual position to a target position can be corrected, on the basis of the target position signal Vs from the D/A converter 2 and the actual position signal Vp from a rack position sensor 7. As a result, the linear solenoid 5 generates an attracting force corresponding to the current value, and drives a rack 6 as a fuel regulating member. In this case, control constants are corrected in correspondence to the width of change in the position of the rack 6, and further they are maintained for a prescribed time, so that the abnormal action of the rack 6 can be prevented.

摘要： PURPOSE:To set the maximum ideal injection in the entire rotary region of engine by deciding whether it is in the maximum injection region in accordance to the error between the ideal maximum injection and the actual level. CONSTITUTION:The engine operating conditions are detected through a rotation sensor 11, suction air pressure sensor 22 and suction air temperature sensor 23. The actual position of a fuel adjusting member in a fuel injection pump is detected through a spill ring position sensor 13. The maximum position of fuel regulating member for fuel injection pump is operated from the operating condition detecting signal to operate the error between the maximum position and the actual position of said regulating member. Then said error is compared with predetermined level to decide whether it is in the maximum injection region and if it is, the maximum injection is obtained in accordance to the error. Consequently the maximum ideal injection can be set in the entire rotary region of engine.

摘要： PURPOSE:To surely detect a fault in either of digital computers and their input systems. CONSTITUTION:A control device for internal combustion engine is provided with a pair of calculating digital computers ECC1 and ECC2, and a diagnostic digital computer DECU. In the digital computers ECU1 and ECU2, the control amount of an engine is calculated based on signals input from multiple sensors 30a to 35a and 30b to 35b, and the calculated control amount is transferred to the digital computer DECU. In the digital computer DECU, an engine speed NE is calculated based on pulse signals input from NE sensors 30a and 30b, and a predicted control amount predicted from the engine speed NE is compared with the control amount transferred from the digital computers ECU1 and ECU2. When there is a difference between them, it is judged that either of the digital computers ECU1 and ECU2 and their input systems is faulty.

摘要： PURPOSE:To reduce a displacement of a reference position of a to-be-shifted member by a thermal expansion of a laminated piezoelectric body by a method wherein the to-be-shifted member which is shifted by an expansion or contraction operation of two or more laminated piezoelectric bodies inside a case member is arranged and installed so as to be sandwiched between the laminated piezoelectric bodies. CONSTITUTION:Two laminated piezoelectric bodies 15a, 15b are arranged so as to be expanded or contracted in such a way that a flapper 14 is sandwiched inside a piezoelectric-body case 12. Even when the laminated piezoelectric bodies 15a, 15b are expanded or contracted by a change in an ambient temperature or by generated heat, both are expanded or contracted by an identical amount; this amount is absorbed by dish springs 17a, 17b; the flapper 14 is not shifted. Accordingly, a displacement of a reference position of the flapper 14 is reduced; a stable servomechanism can be constituted. When a prescribed positive or negative voltage is applied to the laminated piezoelectric body 15a or 15b, this body is expanded or contracted and shifts the flapper 14.

摘要： PURPOSE:To enable a constant speed running to be accomplished by configurating a device in such a manner that a required quantity of fuel and a required change gear ratio are determined based on both an engine necessary horse power which is computed on the basis of a deviation of an actual speed, and the actual speed so as to control a fuel feed device and the transmission. CONSTITUTION:An actual speed NW from a speed sensor 5, and a target speed NWC from a target speed command device 6 are inputted into No.1 arithmetic circuit 8 of a control device 7. An engine necessary horse power is computed based on the computed difference between the actual speed NW and the target speed NWO and then is inputted into No.2 arithmetic circuit 9 computes the obtained data together with the actual speed NW and determines a required change gear ratio (e) and a required quantity of fuel Q, signals for which are then outputted to the stepless transmission 3 and a fuel feed device 2 respective ly in controlling both the engine 1 and the transmission 3 so as to maintain a constant speed. This configuration enables a constant speed running to be accomplished.
