A new technique in the automobile is emerging nowadays to control the noise produced by the engine during a combustion process. The effort has been made by using electronics medium and injection pressure method to reduce the noise produced by the engines in case of the single cylinder. Fuel pressure and temperature has a great effect on the performance of engine and the noise which is produced by the engines during its operation and to control over this problem is challenging for the researchers so the emerging technique of ECU has been introduced in this study ti control the noise and eventually got good results and the results clearly showed the noise reduction by using these ECU control technique.
