FIELD: chemistry.
SUBSTANCE: present invention relates to use of lubricating oil in a diesel engine. Described is use of lubricating oil in a diesel engine, which is equipped with a regenerating trap for suspended particles of exhaust emissions, where the lubricating oil contains a base oil component with paraffin content of more than 80 wt % with more than 98 wt % content of saturated hydrocarbons and contains several isoparaffins having n, n+1, n+2, n+3 and n+4 carbon atoms, where n can range from 15 to 40, and a method of operating a diesel engine equipped with a trap for suspended particles of exhaust emissions, which involves lubricating the diesel engine with said lubricating oil.
EFFECT: reduced frequency of cleaning up traps for suspended particles, reduced NOx emissions and, consequently, low power consumption.
