Nine engine operating and design parameters were investigated with respect to their effects on ignition timing. Equivalence ratio (0.2a¼0.4), EGR (5%, 20%, and 40%), Load (7a¼13 mg/cycle), RPM (750a¼3750), wall temperature (400K, 450K), swirl (0.93, 3.93), compression ratio (12.5, 16), piston geometry (bowl, pancake), and crevice volume (1%, 4%, and 8%) are those nine parameters. The effects of these parameters on combustion efficiency and burning rate were also investigated with controlled ignition timing.1.1.1 Toyota UNIBUS Toyota uniform bulky combustion system (UNIBUS) is introduced in 2000 in Japanese Market [Hasegawa and Yanagihara, 2003]. The engine is a Toyota 1KD-FTV. It is two-staged injection diesel combustion. The first anbsp;...
