Abstract

Shortage of fuel and increasing environmental pollution is one of the concerns for publics to alert about this problem. Therefore, study after study undertaken by researchers to find alternative sources to replace fuel sources. The study was done by researcher trace a variety of fuel sources that can replace the existing fuel. For example, biodiesel from plant sources is one of the new sources explored. Many viewers say the source of biodiesel from plants can reduce the rate of emissions and improve engine performance. This project investigated the performance and emission of engine without any substantial hardware modification. The fuel from jatropha biodiesel blend with diesel will be used in the engine. In this project, performance of engine such as torque, power and brake specific fuel consumption were evaluated. Other than that, gas emission from engine such as hydrocarbon (HC) and carbon dioxide (CO2) also were measured. It was found that the JB5 gave the best performance and similar with D2. The lower blends of biodiesel increase the power of engine and reduce the brake specific fuel consumption. The gas emissions from combustion chamber are reduced with increase in biodiesel concentration. The experiment results proved that the use of biodiesel in compression ignition engines is viable alternative to diesel.
