A Feasibility Study of Pilot Injection in TICS (Timing and Injection Rate Control System) 940195

This paper describes the development status of TICS pilot injection. Stable pilot injection with an appropriate pilot injection quantity and pilot-main injection interval can be obtained by the newly introduced pilot injection element in TICS. A single cylinder NA engine has been tested to clarify the effect of pilot injection. The results show the advantages of pilot injection for NOx, HC, BSFC and noise reduction. The pilot quantity is required to be as small as possible in order to minimize the penalty in smoke emission. Finally, the latest results of the feasibility study of TICS pilot injection are discussed.
