Abstract

PURPOSE: To detect the knocking at a high accuracy by detecting the engine vibration of high frequency.
CONSTITUTION: The vibration detector 2 outputs the electric signal according to the vibration of the engine 1 and receiving the signal, the knocking discriminator circuit 3 determines whether the knocking exsists or not. The knocking discrimination signal is inputted into the ignition period computing circuit 5, which determines the ignition period receiving the discrimination signal in addition to the signal of the engine revolusions, load, water temperature and the like from the engine condition detector 4. The knocking discriminator circuit 3 determines the existence of the knocking by detecting the engine vibraton of high frequency.
