FIELD: engines and pumps.
SUBSTANCE: coolant flow rate control in ICE including crankcase and water pump. Material temperature corresponding to crankcase hottest point is estimated proceeding from accumulated energy E calculated by integral of return power (Pcau(t)) corresponding to power transferred to coolant if it is driven. Invention covers also the coolant flow rate control system motor vehicle.
EFFECT: accurate assessment of engine temperature and water pump efficiency.
