Performance Evaluation of a Diesel Engine Using Biogas From Locality Developed Plant

Abstract

The idea of biogas as a diesel fuel substitute is not new. It is a very attractive alternative, especially in countries rich in agricultural products and poor in petroleum resources. It can be concluded from the study that while running a diesel engine in dual fuel mode on diesel and biogas saved almost 40% to 45% diesel fuel. Bio gas was used in a single cylinder, direct-injection, compression ignition engine, which has been modified to operate under dual-fuel condition to generate electricity. The primary fuel is biogas, which is ignited by a pilot diesel liquid injection. It is therefore recommended that fixed dome biogas digester may be installed in such agroecological zones like Islamabad. As the price of diesel is rising in the global market at present, this dual fuel system will help the Bangladesh firms to reduce costs and increase production by saving diesel.
