Effect of Wet-Ethanol on Fuel Consumption and Soot Emissions on Direct Injection Diesel Engines with Jatropha and Solar Cold EGR System

Abstract

Diesel engines have excellent performance and high efficiency. The increasing use of diesel engines has resulted in increased use of fossil fuels and air pollution. Addition of castor oil to diesel fuel increases smoke emissions due to higher viscosity than diesel fuel. Therefore the addition of wet-methanol in diesel fuel and European oil can solve the problem of diesel engines. This study aims to evaluate the effect of adding wet ethanol to fuel consumption and soot diesel engine emissions. The test uses the Isuzu 4JB1 engine equipped with the Cold EGR system. The percentage mixture of wet ethanol fuel is 5%, 10%, and 15% based on volume. The results showed that the addition of Wet-ethanol to diesel and fuel mixtures in Europe caused a decrease in the value of fuel consumption and soot emissions. The highest reduction in smoke opacity occurred on the DJ10WE15 fuel of 16% while the reduction in fuel consumption occurred in DJ10WE10 fuel by 11%.
