A novel approach to utilize esterified rice bran oil as an additive with gasoline and ethanol blends in MPFI SI engine

摘要

In this work, we have attempted to add biodiesel as an additive with gasoline and ethanol blend to analyze the effect on performance and emission characteristics. The esterified rice bran oil is chosen as an additive. This focus of this work is to study the behavior of an SI engine for various blend proportions and to identify the optimum blend proportion that yields better results. MPFI engine was used to conduct the load test with gasoline as the base reference fuel. Blends of gasoline-ethanol and rice bran oil were prepared, and the tests were done for all the blends. The observed results were presented and discussed. Adding ethanol to the gasoline results in improved combustion that causes an increase in brake thermal efficiency and brake power. With esterified rice bran oil as an additive gives a reduction in specific fuel consumption, hydrocarbon emission, and carbon monoxide emissions. The optimum blends that have excellent benefits are identified.
