Abstract
The development of new advanced lubricants is a key factor for the production of cleaner and more durable internal combustion engines. New improved anti-friction and anti-wear additives are required to improve the fuel economy and reduce the greenhouse gases emission. The inclusion of nanoparticles known as solid lubricants (MoS2 and WS2 inorganic fullerenes) in engine oils could help to improve the performance of internal combustion engines. This paper describes the results of the testing activities performed on a fully formulated engine oil incorporating MoS2 nanoparticles. The nano-lubricant allowed demonstrating on the New European Driving Cycle (NEDC) a reduction of 0.9% of fuel consumption with respect to the reference lubricant without nanoparticles.
