Exploring the Effects of DEE Pilot Injection on a Biogas-Fueled HCCI Engine at Different Injection Locations

One of the popular ways to minimise impact emissions produced by engines is enabling alternative fuels. Out many trending options for fuels, biogas provides some unique advantages, such as being considered be environmentally friendly, obeying laws renewable energy and generating smallest carbon footprints. The two major drawbacks traditional diesel are their high rate NOx significant amount soot. best candidates overcoming these issues HCCI engines; can provide better control over generation overall thermal efficiency improved a greater level. These types compatible with both SI CI. Now, understand analyse behaviour HCCI, present work was focused on modified single-cylinder CI engine. It made operate in mode combination biogas, along diethyl ether (DEE), fuel mixture. To achieve combustion, combined air, while DEE acted an ignition source, which introduced at three different locations. In total, experiment performed sixty times so injection position. obtain this information, other parameters, flow rate, torque, methane fraction position, were also incorporated. main results consolidated warping output parameters brake efficiency, equivalence ratio, air–fuel brake-specific consumption. Emission CO, HC, NOx, smoke taken into account. indicate that port higher than manifold injections, lower observed injections.
