Study on the Combustion Process of a 2 Liter Supercharged Intercooled D.I. Diesel Engine, Based on Experimental and Modelled Results

In this paper, a parametric study on the combustion process of a 2 liter supercharged intercooled direct injection Diesel engine is presented, aiming to improve performance and pollutant emissions at a representative operational condition. Future and actual european emission standards have been taken as a reference for optimization. The study is based on the results of experimental tests carried out on a single cylinder research engine, where all the operating conditions are kept under severe control, and on the results of a phenomenological combustion model adjusted to the tested engine.
