Experimental Investigation of the Effect of Fuel Injection Advance on Engine Performance and Exhaust Emission Parameters Using Canola Oil Methyl Ester in a Turbocharged Direct-Injection Diesel Engine

This paper presents the effect of fuel injection advance on engine performance and exhaust emission parameters using a diesel engine running on canola oil methyl ester (COME). COME was produced and tested at full load with various engine speeds by changing fuel injection advance in a turbocharged direct-injection (TDI) diesel engine with four cycles and four cylinders. According to engine performance test results, maximum brake torque (228.2 N m), brake power (80.3 kW), and thermal efficiency (39.77%) and minimum brake-specific fuel consumption (226.24 g kW −1 h −1 ) have been obtained for COME on early fuel injection advance (18° crank angle). In addition, early fuel injection advance for O 2 and CO but late fuel injection advance (12° crank angle) for NO x and CO 2 must be preferred for decreasing exhaust emissions. Exhaust gas temperatures and smoke density increased by an average of 0.33 and 2.69%, respectively, for early fuel injection advance, and these are increased by an average of 1.48 and 13.66%, respectively, for late fuel injection advance.
