Abstract | Pre-chamber ignition system has the potential to reduce burn duration of lean-burn gasoline engine combustion and can achieve reduced knock occurrence from the distributed ignition sources. Pre-chamber ignition produces high velocity turbulent jets and these jets often reach sonic velocity and produce shock waves inside the combustion chamber. These shock waves make knock detection difficult with a conventional surface mounted acoustic knock sensor. This paper discusses how an acoustic knock sensor works with pre-chamber ignition and evaluates different cylinder pressure-based knock detection strategies and proposes a method which eliminates the influence of jet induced oscillations on knock detection. |
