Design and Analysis of New Fuel Injection System in the Intake Manifold

Abstract

The aim of this project is design and analysis of the new fuel injection system in the intake manifold of the 2.0 Liter TDI Common Rail BIN5 ULEV Engine. This research is part of a long-term research study carried out by Dra. Carrie Hall and the Advanced Engine Control Laboratory research team of Illinois Institute of Technology, in which ‘’Nonlinear Model-based Control Strategies for Advanced Fuel-Flexible Multi Cylinder Engines’’ is studied. In this paper the research work is summarized and explained. The first part of the paper includes the theoretical framework in order to understand the current situation of the elements and resources used in this study. This section contains a description of the engine used to carry out the long-term research, the air manifold of the engine explained in more detail, the chosen fuel injectors and the basics to understand the fluid simulation software used in the research. Then the procedure followed for analyzing and designing the new system is detailly explained. In this practical approach, first, the fluid analysis using a CFD simulation software for the actual manifold is carried out and explained in the report. Then, the new design with fuel injector is analyzed. Finally, the conclusions of the research and the guidelines for the future work are set up
