Investigation of B20 preheating effectivity in single cylinder compression ignition engine performance

Abstract

The purpose of this study is to investigate the effectivity of B20 preheating in single cylinder compression ignition engine. Characteristic of fuel viscosity for some variant heating temperatures are explored. Engine performance was also carried out for measuring the impact of preheating the fuel. Cylinder pressure and emission of engine in some preheating fuel temperature conditions are measured. The heating B20 in range temperature 30–50 °C show the viscosity characteristic that full fill the ASTM 6751 and EN14214 standard. The engine performance shows the significant improvement when the B20 was heated at 40 °C prior to CI engine injector. The B20 preheating at 40 °C are the highest cylinder pressure, a lower specific fuel consumption, a lower carbon monoxide, the lowest carbon dioxide, the lowest oxygen content compared to ambient and others fuel temperature.
