解放CA1091型汽车为了提高点火能量,改善起动性能,限制发动机因各种原因产生的连续强烈爆震,延长发动机的使用寿命,首先在点火系中装用了BX-1A型爆震限制器。爆震限制器由印刷电路板组成,置于铝压铸的盒体内,安装在车头右侧内盖板上,爆震传感器为压电共振式,装在气缸盖上。 一、工作原理 1.发动机爆震时,气缸发出特定频率的振动,爆震传感器谐振于此频率,灵敏地检测出爆震信息,并由电压信号输出,而将此信号输入爆震限制器,使触点打开瞬间,
In order to improve the ignition energy, improve the starting performance, limit the engine continuous strong detonation caused by various reasons and prolong the service life of the engine, the Liberation CA1091-type vehicle is equipped with the BX-1A type knock limiter in the ignition system. Knock limiter consists of a printed circuit board, placed in aluminum die-cast box body, mounted on the inner cover on the right side of the front, the knock sensor for piezoelectric resonance, mounted on the cylinder head. First, the working principle 1 engine knock, the cylinder emits a specific frequency vibration, knock sensor resonance at this frequency, the sensitive detection of knock information, and the voltage signal output, and the signal into the knock limiter, Make the contact open moment
