In this paper are presented results of dual fuel diesel engine bench testing carried out by author. The engine was fuelled parallel with two fuels. The second, additional fuel was compressed natural gas (CNG). CNG was injected into engine inlet system before inlet to engine turbocharger. There was installed a pressure transducer in one of engine cylinders and cylinder pressure was registered at the time of testing. There is discussed place and way of pressure sensor installation and impact on quality of indicating signals of the channel connecting the transducer with combustion chamber. The carried out investigations included measurement of emissions and engine indicating completed with the heat release characteristics. There was considered influence of CNG on CO, NOx, THC and NMHC emissions, especially how pollutant emissions depend on the share of methane in fuel. The effect of using natural gas as an additional fuel injected to regular CI engine on heat release rate was investigated, as well as its rate and duration. Discussed the differences between combustion of methane and diesel oil and ways of spreading flames into air-fuel mixture for these two mixed fuels The processes of combustion of diesel oil and methane are totally different. The study searches for the limits of methane content due to knocking combustion. Additive of methane to the diesel fuel is a reason of retarded heat release, decrease of engine efficiency, greater fuel consumption and changes in emissions corresponding to the lag of self-ignition
