The Effects of Canola Oil/Diesel Fuel/Ethanol/N-Butanol/Butyl Di Glycol Fuel Mixtures on Combustion, Exhaust Gas Emissions and Exergy Analysis

Abstract

In recent years, there have been many studies on the widespread use of liquid fuels derived from biomass. A common emphasis in such studies is on fewer exhaust gas emissions and the expansion of renewable fuel production. Biodiesel is considered to be an important type of biomass fuel that is already produced commercially. But the production of biodiesel is laborious and comprises combination of several chemical processes. This study examines the effects of using oil used in biodiesel production with oxygen-rich chemicals on combustion (in-cylinder pressure (Cp), heat release rate (HRR), rate of pressure rise (RoPR), and cumulative heat release (CHR)), exhaust emission values, energy and exergy analysis. In this study, the effects of butyl di glycol use were also investigated and compared with commercially used ethanol and n-butanol. A transesterification method produced from canola oil the biodiesel used in the experiments. The experimental fuels were mixed volumetrically. For this purpose, experiments were carried out with canola biodiesel produced at 20% (D80B20) in diesel fuel and the results of the experiments were recorded. Under the same conditions, experiments were carried out by adding ethanol (D60C20E20), n-butanol (D60C20B20), butyl di glycol (D60C20G20) at a rate of 20% by volume to the canola oil added to the diesel fuel. The lowest values in terms of thermal and exergy efficiency were obtained in D60C20G20 fuel at all engine loads. Also, the highest entropy generation was calculated at all engine loads for this fuel blend.
