Operation of a Small Diesel Engine Using Unrefined Rapeseed Oil as Fuel (Part 1)

Load Performance Tests

Abstract

Many studies on plant oils as substitute fuel for diesel engine have been carried out actively since the oil price rose in 1973. Substitute plant oils are mainly refined oil and some of unrefined oil of rapeseed oil. In this paper, the authors compared specific fuel consumption, thermal efficiency, exhaust-gas temperature, density of black smoke of exhaust-gas, when rapeseed deacidification oil, light oil and unrefined rapeseed oils were used for small diesel engine.
