Title: Knocking detecting device for engine
Inventor: TAWARA YOSHITAKA
IPC: F02P5/153
Filed: 1988-02-15
Abstract: PURPOSE:To maintain detection accuracy even when the rotating speed of the engine is high and to prevent overlooking effectively by detecting the time between crank angles of the engine as well as the vibration state and deciding that a knocking detected value is larger and larger as the time between crank angles is shorter and shorter. CONSTITUTION:A knock sensor 16 as a vibration detecting means outputs a signal as to the vibration of the engine 1 and a crank angle sensor 17 detects the time between crank angles. Then the knock detecting circuit of a controller 19 compares the output level of the sensor 16 with a prescribed knock decision level by a comparator and decides a knocking state when the detect level exceed decision level. At this time, it is decided that the knocking detected value is larger and larger as the time of crank angles by the sensor 17 is shorter and shorter, and the decision level as a threshold value is fed back so as to converge almost on the maximum value of the output level of the sensor 16. Thus, the probability of knock detection does not decrease even when the engine 1 rotates fast.
