汽油机的爆震往往是由有经验的人用耳听判定的。本文提出一种自动测量发动机爆震强度的方法。爆震是以气缸压力和发动机噪声中的明显的高频振荡脉冲为标志的。气缸压力和发动机噪声的相关函数给出了此振荡脉冲的频率范围。从脉冲振幅的分布可导出爆震强度的量度值。此项研究是由不来梅的克虏伯阿特拉斯电子研究所完成的。
Gasoline knock detonation is often heard by experienced people to judge. This paper presents a method to automatically measure the engine knock strength. Knocking is marked by pronounced high-frequency oscillation pulses in cylinder pressure and engine noise. The correlation function between cylinder pressure and engine noise gives the frequency range of this oscillation pulse. From the distribution of the pulse amplitude, a measure of the knock strength can be derived. The study was completed by Bremen’s Krasnoyars Atlas Institute of Electronics.
