The study of the environmental performance of diesel engines running on natural gas in a wide range of operating conditions is relevant for the further implementation of their transport and transport-technological machines. The paper deals with the use of natural gas as an alternative fuel to improve the environmental performance of a diesel engine. The results of experimental studies on the effect of natural gas and exhaust gas recirculation on the toxicity and smokiness of diesel engine exhaust gases are presented. It is noted that when the diesel engine is running on natural gas with exhaust gas recirculation, the content of nitrogen oxides (NO x ) in the exhaust gases decreases by 43.2%, soot (C) by 5.6 times, carbon dioxide (CO 2 ) by 33.3%, carbon oxides (CO) by 10.0%.
