    • An output signal of a vibration sensor mounted on an internal combustion engine is compared with a background noise reference signal to produce a knock signal which can accurately represent the intensity of knocking. The background noise level signal is produced by averaging a component of the vibration sensor output signal which represents the vibration of the engine other than knock-induced vibration. In order to produce a feedback signal for inhibiting the knock induced component of the sensor output signal, a first comparator compares the sensor output signal with a first reference signal having a sufficiently low level. Knock signal is produced by a second comparator which receives a second reference signal, which is proportional to the first reference signal but having sufficiently higher level, thereby enabling a precise determination of knock intensity.
    • 安装在内燃机上的振动传感器的输出信号与背景噪声参考信号进行比较,以产生可以准确地表示爆震强度的爆震信号。 背景噪声电平信号是通过对表示发生器的振动以外的振动传感器输出信号的分量进行平均而产生的,而不是敲击引起的振动。 为了产生用于抑制传感器输出信号的敲击感应分量的反馈信号,第一比较器将传感器输出信号与具有足够低电平的第一参考信号进行比较。 敲击信号由第二比较器产生,第二比较器接收与第一参考信号成比例但具有足够高的电平的第二参考信号,由此能够精确地确定爆震强度。
