Influence of Synthesis Gas Composition on Internal Combustion Engine Parameters

The presented article deals with the possibility of using synthesis gas produced from municipal waste in a spark-ignition combustion engine intended for a micro-cogeneration unit. The subject of investigation is the effect of fuel composition on the internal parameters of the internal combustion engine analysed from the course of pressure in the cylinder. The analysis shows that, in general, increasing the proportion of hydrogen increases the pressure rise rate as well as the rate of heat release in the cylinder. The presented results will serve to understand the processes taking place in the combustion engine as well as the importance of the composition of synthesis gas produced from renewable energy sources in order to achieve the highest possible energy and economic evaluation in the cogeneration unit.
