Content
Knocking is an important issue in improving the efficiency of spark ignition engines. It can be detected by photographing with high-speed cameras or measuring in-cylinder pressure or engine vibration or engine radiation sound. However, these methods each have the problems for example sensor damage risk or necessity of machining the engine. In this paper, we propose the efficient measurement method and the effective evaluation method with the restricted measurement results for engine knocking detection by utilizing the simultaneous measurement results of knocking with these sensors.
