Limited oil resources, combined with the need to stem the toxic emissions to the atmosphere, necessitate seeking alternative fuels for combustion engines. According to forecasts, natural gas will be one of those fuels whose importance is likely to increase in future. Because of its properties, natural gas can be used directly in spark-ignition engines. When natural gas is used as fuel in much more efficient self-ignition engines, it is necessary to use dual fuelling. This paper presents the effect of the proportion of natural gas in the feed dose on the course of the combustion process in a turbocharged self-ignition engine. The engine was controlled by the Common Rail fuel system, programmed for single-fuel operation.
