    Abstract: This invention is based on a method for monitoring a cooling fluid circuit (16) of an internal combustion engine (10), with at least one heat exchanger (18, 22), a regulating valve (26), a cooling fluid pump (32), and an electronic control unit (76). The invention proposes that the control unit (76) predetermine a permissible upper and lower deviation of a reference parameter from a desired value, based on operating parameters of the internal combustion engine (10) and with the aid of deviation characteristic fields (56, 58), and that it compare these permissible upper and lower deviations to a difference between a desired value and an actual value of the reference parameter, wherein the actual value is determined based on parameters of the volumetric flow of the cooling fluid, possibly with the aid of characteristic fields (42, 46, 74).

    Abstract: A cooling system for an internal combustion engine of a motor-vehicle has two separate cooling circuits for the cylinder head and the engine block. The cooling fluid which flows through the cylinder head circulates through a radiator in all operating conditions of the cooling system. The cooling fluid which flows through the engine block is instead de-routed so that it does not flow through the radiator and, when it comes out of the engine block, is fed into a conduit at the outlet from the head so that the engine block is kept at a temperature greater than that of the head. An electronic control unit controls the adjustment of a pump for activating the circulation of the cooling fluid, and a flow control valve which de-routes a portion of the cooling fluid at the outlet of the pump towards the engine block. The electronic control unit carries out the above regulations as a function of signals directed thereto from a plurality of sensors which are indicative of a number of engine operating parameters.

    Abstract: A method is disclosed for improving fuel economy in an internal combustion engine. The method may involve sensing a temperature of an engine block and determining a block thermal energy representing an ability of the block to reject heat. An open loop control scheme may be used together with the block thermal energy to predict if a coolant in the block is about to enter a boiling condition and, when this is about to occur, to open a block valve to permit a flow of coolant through the block. A closed loop control scheme may be used together with the sensed temperature of the block to determine if a coolant boiling condition is about to occur, and to control the block valve to permit a flow of coolant through the block which is just sufficient to prevent the onset of coolant boiling in the block.

    Abstract: A cooling pump for an internal combustion engine and a cooling system including the pump. The pump is driven by an electrically-operated motor so as to rotate in a positive direction for supplying cooling water in a reservoir tank to the engine and in a reverse direction for returning the cooling water in the engine to the reservoir tank. The cooling system includes a controller that is coupled with the motor of the pump and generates a first control signal for operating the motor to rotate the pump in the reverse direction so as to return the cooling water in the engine to the reservoir tank and generates a second control signal for operating the motor to rotate the pump in the positive direction so as to supply the cooling water in the reservoir tank to the engine, on the basis of an operating condition of the engine.
