Control method of fuel injection timing adjustment device

Abstract

Abstract PURPOSE: To prevent the abnormal increase of capacity in a memory when a program in a fuel injection timing adjustment device is out of order by averaging each actually-detected valve and using the result for a newly-set command to maintain controlling. CONSTITUTION: An injection timing adjustment device 2, an oil pump device 3, and a fuel injection pump 4 are interlocked with a diesel engine 1 via gears 1c, 2c, and 3a. An electromagnetic valve 5F to be opened and closed by the oil pressure of an oil pump 3 is controlled by a microcomputer 5 for adjusting the timing of the injection timing adjustment devive 2. In the computer 5, the program in a memory 5E is processed in a central operation circuit 5B by various signals 5c, 5d, 5e, and so on inputted into an input interface 5A, and the result is outputted through an ouput interface 5D. When the program is out of order, various signals inputted are averaged in the operation circuit 5B, and the averaged value is outputted for controlling the electromagnetic valve 5F.
