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

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 e...
