Improvement in Performance of CI Engine Running with Dual Fuel Mode: Biodiesel & Hydrogen

Abstract

"Rapid depletion of petroleum reserves and the environmental concern demands the replacement of conventional fuel with renewable and alternate fuel to fulfill the demand of energy requirement. Biodiesel fits to be the good replacement in CI engine and extensive research has been done in the field of Biodiesel. In this work, the effect on performance and emission of using biodiesel in IC engine has been reviewed. The emissions of unburnt hydrocarbon, carbon monoxide and particulate matter can be reduced considerably with the use of biodiesel compared to diesel fuel. There is some shortcoming by using of Biodiesel such as high brake specific fuel consumption, lower brake power and brake thermal efficiency, which can be overcome by using supplement fuel like hydrogen along with biodiesel. Further, the review work has been extended to methods of hydrogen production and its usage as a secondary fuel along with biodiesel in the engine.
