AN INVESTIGATION OF INITIATION AND COURSE OF COMBUSTION PROCESS IN SI ENGINE FUELED WITH ALTERNATIVE GAS FUELS AND ITS HYDROGEN BLENDS
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2008, Vol 2008, Issue 64
Abstract
The results of research an influence of fuel kind on combustion process in SI engine are presented in this paper. Selected fuels group include alternative gas fuels: LPG, CNG, hydrogen – CNG blends and unleaded gasoline 95 as a base fuel. SI engine X16SZR in Opel Astra I was investigated. The leaded tests include measurement results of dynamometer chassis test, as well as the detailed analysis of thermodynamic processes inside closed chamber. The aplication “EnComTwo”, which resolves assumptions of mathematical model, was used in analysing of engine thermal balance. Combustion process was investigated in each of individual phases: initiation, dynamical combustion and flame extinguish. The most important parameters were: indicated pressure, heat released, combustion duration and time of combustion.
