Biodiesel fuel blend performance evaluation using a radial finned tube heater

Abstract

PurposeThe purpose of this paper is to experimentally investigate the effect of biodiesel fuel blending and heating on engine torque and power.Design/methodology/approachTo obtain torque and power data, a 1200 AWD dynamometer was used. The 1200 AWD dynamometer is a device used to obtain readings, and is made up of a chassis, inertia roller, roller sensor and converter modules, and can also be connected to a personal computer.FindingsThe result revealed that biodiesel blending and heating significantly affected torque and power. When only biodiesel blend ratio was varied, the highest torque and power were obtained at 30 per cent fuel blending. Also, the highest torque and power were obtained at 20 mm when only a spaced finned tube heater was used. When both variables were combined, the highest torque was obtained at a 20 per cent biodiesel blend and a 10 mm radial radiator finned spacing. Maximum power for two variables was obtained at the 20 per cent blend ratio and 20 mm finned tube heater spacing.Originality/valueA novel radial finned tube heater is used.
