EN The struggle against global warming necessitates the search for new sources of energy, which limit the emission of carbon dioxide into the atmosphere. Among various fuels used to supply energy nowadays, the importance of natural gas is constantly growing. This is caused by the fact that this fuel is characterised by the lowest share of coal among all fossil fuels. Because of its properties, natural gas can be used directly to power spark-ignition engines. The use of this fuel for compression-ignition engines on the other hand is limited due to the high autoignition temperature of methane. Currently, research is being conducted in numerous centres on the possibility of using fuel gases to power CI engines operating in a dual-fuel system. The present article discusses the impact of the share of CNG in the supply dose on the operation of a CI engine. An engine with the Common Rail injection system programmed for mono-fuel operation was used in the research. Based on the conducted tests it has been proved that supplying this type of engine with fuel gas considerably changes the course of the combustion process, which is caused by the fact that the gas and air mixture present in the combustion chamber starts burning now of the autoignition of the first portion of liquid fuel. The obtained test results confirm the necessity to change the injection parameters of the pilot dose of diesel fuel (the timing angle of injection and the pressure of fuel) in cases when this type of engine operates in a dual-fuel system.
