Abstract:
Comparative studies of the corrosion characteristics of motor oils used in internal combustion engines of BelAZ 75131 mining dump trucks using liquefied natural gas - methane - as a motor fuel are presented. It is noted that an increase in the lead concentration in waste oil of internal combustion engines of mining dump trucks can be influenced by the used motor oil when it is interacting with the crank mechanism bearings liners, which have lead in their composition. The research technique is presented. The data on the pH values of the studied neat motor oils and their oil-in-water emulsions are given. It is noted that the effect of moisture and atmospheric oxygen on various types of motor oils of the same manufacturer's brand affects the formation of either water-soluble organic acids that contribute to the corrosion attack on lead or its alloys, or the formation of water-soluble alkaline organic compounds that have a neutral effect on lead and its alloys. This fact suggests that motor oils used in internal combustion engines of mining dump trucks have various corrosion characteristics that eventually affect the content of harmful impurities in waste oils.
