This paper describes the experimental study on the effect of biodiesel oxidation on diesel combustion and emissions. The biodiesel fuel made from the soybean-oil was deliberately oxidized. The progress of oxidation was evaluated by measuring peroxide value, acid value, kinematic viscosity. The auto-ignition characteristics were analyzed based on the constant-volume combustion method. Engine bench tests were carried out using a single-cylinder engine. Obtained results show that the progress of oxidation increases both viscosity and cetane number. The use of oxidized biodiesel increases the combustion pressure and temperature, resulting in increasing NOx emission. However, CO and smoke is decreased without loss of fuel consumption rate. |
