17. A system for an internal combustion engine comprising:
-
an engine block having a cylinder; an oil delivery system coupled to the engine block including an oil reservoir at least partially enclosing an oil emulsion, the oil delivery system providing lubricating oil to at least one cylinder in the engine and including an oil pick-up tube; a positive crankcase ventilation system configured to vent gasses from the oil reservoir to an intake of the engine; an engine block heater coupled to the engine; and a controller configured to adjust heat delivered to the engine, via the block heater, in response to a concentration of water in the oil emulsion, the controller increasing temperature as the concentration increases. - View Dependent Claims (18, 19)
