Title: Controller for engine with supercharger
Inventor: TAKEDA YUUJI
IPC: F02P5/152
Filed: 1982-02-08
Abstract: PURPOSE:To prevent knocking or misfiring during a trouble without delaying the ignition timing by adjusting a supercharge pressure according to the back pressure of exhaust in response to a detection signal informing the trouble of a knocking sensor. CONSTITUTION:The upper limit H and the lower limit L of the average value BG are memorized into a computer 3 beforehand for knocking signals of the abnormal and normal operations in a knocking sensor 11. During the operation, the average value BG of knocking signals is taken to be compared with the lower limit L and if BG>L, it is compared with the upper limit H. If BG<H, the knocking sensor is judged to be normal. On the other hand, when BG<L or BG>H, it is judged to be abnormal and a driving coil 24E of a changeover valve 24 is excited. This opens the valve gates 24B and 24C to switch over the input pressure signal of a diaphragm 23 for controlling a waist gate valve 21 to the exhaust back pressure through lead pipes 26 and 27.
