This study aims to analyse the detailed combustion characteristics of tire derived fuel blends (TDF) in small-size DI diesel engines. From this point of view, the refined TDF and reference diesel fuel (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 (No.2 Diesel fuel), 5.57 CAD (TDF20), 6.56 CAD (TDF40), 8.48 CAD (TDF60), 11.09 CAD (TDF80), and 14.26 CAD (TDF100) for the low engine speeds (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 (HRRmax), a higher peak value of in-cylinder pressure (Pmax) and a higher rate of pressure rise (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.
