One of the major losses occurring in the engine of an automobile is due to friction between its moving partsThis misfortune is huge and around 15 % of the absolute loss of vitality and directly affects the productivity and toughness of the motor. This work results shows there is significant reduce in friction due to addition of nano particles to the base oil . nickel and copper nanoparticles are added at 0.2 %wt, 0.3 %wt. 0.4 %wt to base oil (Castrol SAE 10W30 4T engine oil) by stirring and later sonication was done by sonicator machine for 3hours. Anti-wear properties were obtained using pin on disc machine under different loads and sliding speed of 1m/s for 2 min. This study led to following conclusion that at 0.4%wt of NiO and 0.4%wt of CuO Nano lubricant exhibited reduction in coefficient of friction when compared to other composition of lubricating oil. Mechanical efficiency and Brake thermal efficiency of four stroke single cylinder diesel engine results was evaluated and compared.Refference:
