Abstract
The demand for reduced pollutant emissions has motivated various technological advances in commercial diesel engines. The challenge for the direct injection diesel engines today is to reduce harmful emissions of diesel engines, such as Particulate Matter (PM) and Nitrogen oxides (NOx), and enhance the fuel efficiency and power. To meet this challenge, more accurate control of injection parameters such as the injection timing, injection rate, and injection quantity is required. A comprehensive study is carried out in order to better understand combustion behavior in a direct injection diesel engine working under different injection strategies particularly with post and pre-injections and number of injection. The objective of the study described in this paper is to explore the potential of multiple injection patterns with a common rail system in light duty diesel engines. Experiment results covered influence of pre and post injection at different speeds and loads typical to engine conditions under emission and non-emission zones. The analysis shows that impact of injection parameters including the start of fuel delivery, its duration and amount under all modes of engine speed. The engine being tested was a 3.8 l four cylinder engine equipped with a common-rail injection system and waste gate turbocharger. Experimental results show the comparison between single injection and multiple injections in comparable to performance and BSFC.
