An internal combustion engine is highly susceptible to mechanical noises. They originate from combustion and mechanical motion of engine components, and cannot be avoided with an engine at a normal operation. However,<br/> abnormal engine noises at a specific period can occur due to various reasons. Here in this study, four cases of<br/> undesirable engine noises were investigated. To identity the mechanisms of engine noises, accelerations and movements of interested engine components were measured using accelerometers and gap sensors, respectively. Through the analysis of these experimental data, mechanisms for each case were found and provide the solutions for the reduction of the noises.<br/>
