/Lubricating Fluid For Internal Combustion Engines Fueled With Alternative Combustion Fuels Having High Auto-ignition Temperatures
Abstract
A lubricating oil composition configured for lubricating an internal combustion engine fueled with an alternative fuel having an auto-ignition temperature greater than about 700K. The lubricating oil composition includes select amounts of a viscosity modifier olefin copolymer and/or a select detergent system to mitigate stochastic pre-ignition in internal combustion engines when fueled with the alternative fuels.
