| Abstract(E) | Rapid combustion is being attempted as a means of improving thermal efficiency of internal combustion engines, but rapid combustion deteriorates the vehicle interior noise level. This study focused on the piston system as a phenomenon of noise and vibration caused by combustion. The results of a study to achieve both noise and vibration and thermal efficiency at various engine speed and load by using the excitation force indicators of the piston system are reported. |
