EFFICIENCY IMPROVEMENT OF SINGLE CYLINDER DIESEL ENGINE BY THE USE OF DIESEL BLENDS

Abstract

The world is being modernized and industrialized day by day. As a result vehicles and engines are increasing. But energy sources used in these engines are limited and decreasing gradually. The rapidly depleting conventional petroleum resources have promoted research for alternative fuels for diesel engines. Bio-fuel, a promising substitute as an alternative fuel has got significant attention due to the limited sources of conventional fuels and environmental concern. From different possible options, fuels derived from vegetable oil present promising renewable substitutes for fossil fuels. The utilization of Straight vegetable oil fuel in diesel engine fuel has main the advantage of eliminating the energy, cost and time consumed in biodiesel production. Oil derived from soyabean plant has been considered as a sustainable alternate fuel for diesel engine. The use of straight vegetable oil encounters problem due to its high viscosity, poor volatility and cold flow
