Nanolubricants for diesel engines: related emissions and

compatibility with the after-treatment catalysts

Authors

The effect of the lubricant oil additivated with MoS2 nanopowders was assessed through a set

of full-scale tests on a real diesel engine – several engine points and cooling water temperatures were investigated for both a reference oil and a MoS2-additivated one. The

emission abetment efficiency of the DOC and DPF reduces the gas and solid pollutants obtained with the MoS2-additivated oil to levels equivalent to the ones reached with the

reference oil. An endurance test of 100 h (equivalent to 10,000 km) proved the stability of the catalytic system and the suitability of commercial after-treatment catalysts to cope with the emission modifications induced by the inclusion of nanoadditives in the oil matrix.
