In the present study, the effects of two different camelina biodiesel fuels obtained through transesterification on engine power and torque performance and emissions and fuel combustion characteristics of these fuels compared to diesel fuel were determined particularly focusing on new blend ratios of B7 and B100, which the European Union has been specifically studying on. Heat release rate calculations, which are an important parameter for the engine characterizing the combustion process that occurs depending on cylinder pressure and crank angle, and mass fraction burned (MFB) in each individual engine cycle, which describes the process of chemical energy release as a function of crank angle, were determined in the study. Maximum HRR (Heat Release Rate) at 2500 rpm and 4000 rpm was found as 35 J/Crank Angle Degree. MFB values at 2500 rpm and in blends were found as 100% after 30 degrees (ATDC), at 4000 rpm as 100% after 34 degrees (ATDC). Temperature variation depending on crank angle and blends was found to be a maximum of 1900 K after 18 degrees (ATDC). (C) 2015 Elsevier Ltd. All rights reserved.
