Abstract
Improvements in the fuel economy of internal combustion engines is achieved by various means, including reduction of the frictional power losses. The authors examine a method of improving the antifriction properties of motor oil in the example of M-10G/sub 2/ oil by the incorporation of additives that influence the frictional force and wear. The additives used in this work were molybdenum dithiophosphate and dithiocarbamate, zinc dithiophosphate, and bis-xanthate disulfide. Zinc dithiophosphate is used as an antiwear additive in formulating motor oils at various quality levels; oil-soluble complex compounds of molybdenum are used as antifriction additives in motor oils; bis-xanthate disulfide is used mainly as an additive in break-in oils (for example, OM-2).
