The diesel engine has higher thermal efficiency than the gasoline engine and this directly relates to increase in fuel economy. However, nitrogen oxides (NOx) and particulate matter (PM) emissions as a result of diesel fuel combustion characteristics raise major concerns. The combustion and emission parameters under various fuel injection advance angles in a compression-ignition engine fuelled with diesel–gasoline blends were investigated. The aim of this study is to determine the effect of injection timing to performance of two cylinders, four stroke, common rail direct injection diesel engine. The fuel mixtures have been prepared by addition of gasoline to diesel fuel from 0 to 10% with an increment of 5% by volume. The tests were conducted at different injection timings for various loads at 1500 rpm. The results showed that; the maximum brake thermal efficiency has been obtained in 20 Nm torque for conventional diesel combustion at the injection timing of 352-357 CA and the maximum in-cylinder pressure has been gained in 30 Nm torque for conventional diesel combustion at the injection timing of 342-348 CA. CO and HC emission increased when we adding gasoline to diesel fuel. When we are going to close TDC by angle firstly decreasing then increasing. CO2 emissions shows extremely fluctuation. But NOx emission decreased for all test by adding gasoline to diesel fuel.
