NATURAL GAS COMBUSTION IN DIESEL ENGINES
The article deals with the use of alternative fuels for natural gas (NG) diesel engines. A distinctive feature of the processes of mixture formation and combustion in a diesel engine running on a NG with a ignition portion of diesel fuel will be, in comparison with the diesel process (DP), heterogeneity of the fuel mixture in terms of the cylinder volume, there is a completely different evaporability of the fuel and there is no coincidence in the time of the processes of formation of the fuel-air mixture and its combustion. Consequently, the use of alternative fuels with different chemical composition and local conditions leads to distinctive indicators of the combustion process. Therefore, for the scientific representation of the actual picture of the combustion process of diesel running on NG, indexing of its working process and a detailed description of the combustion process is carried out.
