Comparison of Performance and Combustion Characteristics of Diesel Fuel and Vegetable Oils in DI Diesel Engine 2008-01-1639
GT-Power, an engine modeling software, is used to study the combustion characteristics of cottonseed, linseed and peanut oils in a heavy-duty direct-injection diesel engine. The fuel properties library in GT-Power is expanded to include cottonseed oil, linseed oil and peanut oil, using either theoretical methods or experimental measurements. The numerical model is calibrated with experimental data and good agreement is observed. The simulation results show that combustion characteristics and engine performances differ when vegetable oil is used instead of no. 2 diesel fuel. Raising the injection pressure significantly alters the combustion characteristics without improving the brake performances. However, higher injection pressure does reduce both NOx emission and combustion noise.
