Filed: 1982-10-15
Abstract: PURPOSE:To prevent a point of time, when noise vibration occurs, from being erroneously detected as the starting time of injection and to enable high-precise measurement of fuel injection timing, by a method wherein a point of time, when it is detected that the vibration present right before detection of completion of fuel injection attains the amplitude prevailing at the starting of injection, is determined as the starting of fuel injection. CONSTITUTION:After starting of operation, a valve opening signal PO from an injection start detecting circuit 5, a valve closing signal PC from an injection completion detecting circuit 10, a top dead center signal PT from a top dead center detecting circuit 16, and a number of revolutions signal indicating the number of revolutions of an engine are inputted to a measuring circuit 19. Based on these input signals, the count value of a counter 20, counting a clock pulse of a specified period, is stored in the given address of a memory 21. Based on the count value, i.e., a memory value, a fuel injection start timing is determined, a top dead center period is computed, a fuel injection time and an injection advance angle are measured, and the measurements are displayed through a display circuit 22 on a display device 23. This prevents erroneous detection of a point of time, when a noise signal is generated before injection starts, as the starting of injection.
