Study of corrosion characteristics of motor oils used in gas-diesel engines of BelAZ mining dump trucks

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