Effect of Combustion Chamber Shapes on the Performance of Duel Fuel Engine Operated on Rice Bran Oil Methyl Ester and Producer Gas

Diesel engines are widely used for transport and power generation applications because of their high thermal efficiency, and their easy adoption for power generation applications has been increasing recently. However, there is demand for better performance, lower noise and vibration and greater levels of lower emissions and also due to increasing energy demand, decrease in fossil fuel reserve in the earth crust and harmful exhaust gases have focused major attention on renewable and alternative fuels. To overcome and in meeting these demands, the dual fuel engine, enabling the use of renewable fuels such as biodiesels and producer gas attracts much attention.

To meet the challenge, it is essential in implementing new technologies and methods that improve the efficiency of dual fuel engine used for transport and power generation. Renewable energy sources can supply the energy for longer periods of time than that of fossil fuels and have many advantages. Liquid biodiesels are more suitable for diesel engine applications as their properties are closer to diesel. The main challenge facing by producer gas fueled dual fuel engine include the limited range of operability, quality of producer gas and sensitivity to air/fuel mixture preparation as well as in-cylinder combustion related conditions. However, there are some significant obstacles facing the potential practical application of producer gas combustion in a dual fuel engine.  Read more>>>>>>>>>>>>>>
