Effects of fuel injection parameters on emission characteristics of diesel engines operating on various biodiesel: A review

Many researches have been carried out towards the reduction in noxious emissions from diesel engines. This paper reviews the studies on the outcomes of operating parameters discrepancy on the engine emission issues carried out by various authors in different diesel engines fuelled with biodiesel from different feedstocks. The main goal of this paper is to enlighten the momentous of injection parameters like injection timing and injection pressure on the engine emission characteristics. This paper touches upon the advancement and retardation methods of fuel injection timing and injection pressure to inspect the engine emission indicators such as carbon monoxide, hydrocarbon, oxides of nitrogen, smoke, particulate matter and carbon dioxide contents. Comparative evaluation has been conversed accompanied by apropos causes for the deviation of emission characteristics. (C) 2016 Elsevier Ltd. All rights reserved.
