Title: Controller for engine
Inventor: HIRAKI HIKOSABURO
IPC: F02D45/00
Filed: 1986-07-04
Abstract: PURPOSE:To avoid the reduction of the working efficiency due to the reduction of car speed by increasing the engine output over the stationary allowable output when the hydraulic pressure of a hydraulic actuator for driving a work ing machine exceeds a prescribed value, in a heavy work. CONSTITUTION:A controller 7 reads the allowable max injection quantity corresponding to the number of revolution from the signal of an engine revolution sensor 3. When the hydraulic pressure of a pressure sensor 4 on a working machine exceeds a prescribed value in the heavy work by the working machine, the controller 7 outputs the second aimed injection quantity which is obtained by increasing the allowable max injection quantity by a prescribed injection quantity, and converts said injection quantity to a rack position signal. A control rack 8 is feedback-controlled by the signal. Since the injection quantity is increased over the allowable max injection quantity, also the engine output is increased over the stationary allowable output, and also the car speed is not reduced. When the hydraulic pressure of the pressure sensor 4 does not reach a prescribed value, the injection quantity is not increased, and also the engine output does not exceed the stationary allowable output.

Filed: 1989-06-20
Abstract: PURPOSE:To ensure safety during malfunction of a microcomputer by a method wherein when an air purifying means is brought into an operation state and a heating means is brought into a inoperative state, the microcomputer releases a self-holding means. CONSTITUTION:A parallel circuit is formed with a coil 3a of a relay 3 for driving an air purifying means 6 and a contact 10b of a relay 10 for a self- holding circuit. Operation of a heating means 4 is stopped. When only the air purifying means 6 is operated, a relay 2 for drive is brought into an OFF-state, a contact 2b is brought into an ON-state, and an output signal D is brought into an L-state by means of an output signal B from a microcomputer 1. This operation brings a transistor 9 into an OFF-state, brings a relay 10 for a self- holding circuit into an OFF-state, and brings the contact 10b into an opening state. A manual switch 7 is formed with a switch which is kept at an ON-state only during operation and at an OFF-state during inoperation. The relay 10 for a self-holding circuit is kept at an OFF-state. This constitution enables provision of a control device which prevents the heating means 4 from being brought into an operation state even when the microcomputer 1 effects malfunction.
