Experimental optimization of injection parameters to enhance combustion characteristics of engine on using CE40 fuel

Abstract

Recently, the automobile sector has been moving to dual-fuel vehicles for the hazardous emissions of internal compression ignition engine to be diminished. The purpose of this experimental optimization is to learn how different configurations of injector nozzle holes, fuel injection pressure, and injection time affect the performance, emission, and combustion of a CI engine using CE40 fuel. The brake thermal efficiency has been exhibited an increase to 5.48%, accompanied by a 30.65% reduction in fuel consumption under the influence of a 22 MN/m² higher injection pressure. 44% of HC has been reduced at 29^o bTDC crank angle, and 31% of CO has been controlled with the help of the five-hole nozzle. This experiment raises the NO_x emission at increased injector pressure and enhances it with a five-hole injector. However, the emissions of carbon monoxide and hydrocarbons are reduced.
