Abstract
The experimental background is to determine a solution for combating the energy
shortage issue using renewable fossil fuel to alternative energy sources in diesel engine.
Biofuels is the choice of renewable fuels since the past decade as renewable and
biodegradable fuels. Globally, the urge and support of government to promote the usage of
biofuels mixing with diesel blend for the betterment of environment without jeopardizing
the engine performance. Most of the researchers believe fossil fuels is a source of clean
energy when mixed with biofuel, and they have conducted research of utilizing biofuels in
diesel engine. The experiment is conducted by utilizing biodiesel-diesel blend (B0, B20,
B40, B60, B80 and B100), at various engine load such as 25%, 50%, 75% and 100% and
engine speed of idle, 2350rpm, 3100rpm and 3850rpm to test the performance and
emissions of a diesel engine. The performance results are the Power, Brake Thermal
Efficiency (BTE), Brake Specific Fuel Consumption (BSFC), and emissions such as
Nitrogen Oxide (NOx) and Soot. For all the tested biodiesel data is obtained by using the
Labview and DeweSoft software, simulation is conducted by using the RK Diesel software
to verify the data accuracy, and the choosing of best biodiesel mixing ratio, engine speed
and engine load, to find the maximum BTE and BSFC with the minimum achievable
emissions of NOx and soot is conducted by accessing the Design-Expert software. The
results of the experiments indicate that biodiesel B60, speed of 2070rpm, Load of 55% is
the optimum choice to maximize the BSFC, BTE and engine power, with the minimization
of the engine emissions performance.
