The article considers the issues of using compressed natural gas as alternative vehicle
fuel and reducing the toxicity of diesel engine exhaust gases. Special attention is paid to
the problems of nitrogen oxides generation and decomposition in the cylinder of a diesel
engine operating on natural gas, its impact on the combustion process. The article pre-
sents the results of experimental studies of the effect of compressed natural gas and recy-
cling on the effective characteristics, the toxicity and opacity of exhaust gases.
Charac-
teristics of heat generation are studied in details and determined, the values of volume
content of nitrogen oxides in the cylinder against the change of crankshaft rotation angle
are obtained.
Keywords:
diesel, compressed natural gas, recirculation, nitrogen oxides, toxicity.
