Analysis of Compression Ignition Engine Performance and Emission Parameters using Simulink at Different Engine Operating Conditions
要約
Diesel engines are widely used as a power source of
engineering machinery, automobiles, and shipping equipment
due to their excellent drivability and thermal efficiency. At the same time, diesel engines are major contributors of various
types of air pollutant emissions such as Carbon monoxide (CO),
Oxides of Nitrogen (NOx), Particulate matter (PM), and other
harmful compounds. With the increasing concern of
environmental protection and more stringent government
regulation on exhaust emissions, reduction in engine emissions
has become a major research task in engine development. It has
become necessary to predict the performance and emission
characteristics of diesel engines without conducting
experiments to avoid the cost of experimentation and delay in
conduction and analysis of results. The focus of the present
study is the modelling of performance and emission
characteristics of Diesel engines at various engine speeds and
loads, using modified versions of Simulink® pre-built models. In this work, a Simulink® model was created using Powertrain BlocksetTM components. The model returned several emission and performance parameters as output. It was observed, for a multicylinder Compression Ignition configuration, the result plots matched data obtained from physical testing of a similarly configured engine.
