Analyze and Mathematical Modeling of the Combustion Process of One-Cylinder Spark Ignited Hydrogen Fueled Engine

摘要

Hydrogen is a potential replacement for fossil fuels in the transportation sector because it is clean, renewable and has the possibility to reduce emission of criteria pollutants (NOx) and the effect on global warming via carbon dioxide which is negligible. The present research study is devoted to analyze the process of combustion of hydrogen in the four-cycle one-cylinder spark ignited engine and to concern with developing a numerical model that consider the features of process of combustion, to estimate the influence of the constructive and the control parameters of the engine on process of combustion. It is found that the curve of speed of combustion at hydrogen blending is close to the triangular form. It was found that varying the compression ratio and, to a lesser extent, the ignition timing influences the duration and the dynamics of the combustion process, more than at varying the air–fuel ratio.
