    Abstract: A method of monitoring an engine coolant system includes modeling the total energy stored within an engine coolant. If an actual temperature of the engine coolant is below a minimum target temperature, the modeled total energy stored within the energy coolant is compared to a maximum stored energy limit to determine if sufficient energy exists within the engine coolant to heat the engine coolant to a temperature equal to or greater than the minimum target temperature. The engine coolant system fails the diagnostic check when the modeled total energy stored within the energy coolant is greater than the maximum stored energy limit, and the minimum target temperature has not been reached.

  • Patent number: 8370052
    Abstract: An onboard cooling system diagnostic strategy utilizes at least one temperature sensor fluidly positioned between an electronically controlled engine and a thermostat. The diagnostic algorithm operates by monitoring coolant temperature during engine startup. By comparing the actual coolant temperature during engine start-up to a predicted coolant temperature that should occur if no cooling system error is present, a cooling system fault condition may be identified. If a cooling system fault is detected, the diagnostic logic may activate the engine cooling fan or intrusively open an electrically controlled thermostat while monitoring the coolant temperature response to the intrusive action. If there is a substantial change in coolant temperature responsive to the intrusive action, this phenomenon can be utilized to correctly distinguish between a thermostat failure and a vehicle configuration error corresponding to an overcooled vehicle.

  • Patent number: 8140246
    Abstract: The present invention relates to a method and system for detecting a presence of a block heater in an automobile. In one embodiment, an automobile includes an engine, a radiator, an engine coolant temperature (“ECT”) sensor, and/or an engine control unit (“ECU”). The radiator delivers coolant to the engine to cool the engine. The ECT sensor is located in a path of the coolant and determines ECT data. The ECU determines a temperature difference between a current maximum temperature of the engine coolant temperature data at a first time period and a current minimum temperature of the engine coolant temperature data at a second time period after the first time period. When the temperature difference is greater than a predetermined temperature threshold, the ECU determines that the block heater is present. When the block heater is present, the ECU masks any engine malfunction detections.

  • Patent number: 8132547
    Abstract: The inventive management system comprises a high-temperature circuit (12) provided with a high-temperature cooling radiator (20), a low-temperature circuit (14) provided with a low-temperature cooling radiator (30, 30a, 30b), wherein the same heat carrier fluid runs through said circuits. Said system also comprises a radiator (36) assignable to first switching means (52) and to second switching means (54) for switching the system from a connected configuration, in which the assignable radiator (36) is connected to the low-temperature circuit (14), to a disconnected configuration, in which the assignable radiator is connected to the high-temperature circuit (12), and vice-versa. The switching means are sequentially actuated after a time-delay during switching from the disconnected configuration to the connected configuration and/or from the connected configuration to the disconnected configuration in order to minimize thermal shocks in the assignable cooling radiator (36).

  • Patent number: 7775268
    Abstract: A vehicle cooling system comprises a vehicle unit, a heat exchanger, a cooling fan, a coolant pump, a three-way valve, and a control unit. The heat exchanger is arranged in the coolant route to selectively receive a coolant from the coolant outlet of the vehicle unit. The cooling fan is arranged to blow cooling air to the heat exchanger. The coolant pump is arranged to circulate the coolant through the coolant route. The three-way valve is arranged to switch the coolant route between a heat exchanger route that passes through the heat exchanger and a bypass route that bypasses the heat exchanger. The control unit is configured to control operation of at least one of the cooling fan, the three-way valve and the coolant pump based on a temperature of the coolant at the heat exchanger and a temperature of the coolant at the coolant outlet of the vehicle unit.

  • Patent number: 7775183
    Abstract: The present invention removes voltage that accumulates over a period of time in an automotive engine cooling system. This accumulation of voltage is provided a path to travel inside the engine and cooling system by the cooling liquid used to cool the vehicles engine. This accumulation of voltage looks for a likable metal to bond with and the constant colliding of the voltage trying to bond with the metal creates damage know as electrolytic metal erosion. Overtime this act of nature erodes and weakens metal cooling system components causing them to fail. This process can lead to the vehicle breaking down due to its engine overheating. The electronic voltage remover is designed to remove and dissipate this harmful voltage from the vehicle's engine cooling system.

  • Patent number: 7524106
    Abstract: There are occasions when an intermittent abnormality occurs in a water temperature sensor that is of a type that does not cause a sudden change in a detection value of the water temperature sensor. The movement of the detection value of the water temperature sensor when this type of abnormality occurs may be, for example, a movement in which the detection value of the water temperature sensor becomes lower even through warm up has been proceeding after engine start up has begun. When this type of movement of the detection value occurs, if the detection value of the water temperature sensor reduces, after engine start up has begun, to a value lower than that when start up began, it is immediately determined based on this fact that an abnormality of the water temperature sensor is occurring.
