Abstract :This study aims to analyse the detailed combustion characteristics of tire derived fuel blends insert ignore into journalissuearticles values(TDF); in small-size DI diesel engines. From this point of view, the refined TDF and reference diesel fuel insert ignore into journalissuearticles values(No.2 Diesel); were blended in various percentages and tested in a single cylinder naturally aspirated DI diesel engine to clarify its detailed combustion characteristics. The experimental test results point out that ignition delay period is ob-served to be 4.32 CAD insert ignore into journalissuearticles values(No.2 Diesel fuel);, 5.57 CAD insert ignore into journalissuearticles values(TDF20);, 6.56 CAD insert ignore into journalissuearticles values(TDF40);, 8.48 CAD insert ignore into journalissuearticles values(TDF60);, 11.09 CAD insert ignore into journalissuearticles values(TDF80);, and 14.26 CAD insert ignore into journalissuearticles values(TDF100); for the low engine speeds insert ignore into journalissuearticles values(1400 rpm);. With the increasing TDF in fuel blends and engine speed, the ignition delay period prolongs more, and the total combustion duration shortens. However, due to the excessively long ignition delay period of TDF100, it is not possible to run the test engine at more than 3000 rpm. TDF blends usually demonstrate a longer premixed combustion period than that of No.2 Diesel, while it exhibits a shorter diffusive combustion period. TDF blends also display a higher maximum value of heat release rate insert ignore into journalissuearticles values(HRRmax);, a higher peak value of in-cylinder pressure insert ignore into journalissuearticles values(Pmax); and a higher rate of pressure rise insert ignore into journalissuearticles values(dP/dCAD);. In addition, combustion events occur late, and the center of combustion moves away from the top dead center into expansion stroke in the case of TDF blends.
