Abstract: A tank having a housing which provides a space for a liquid. An enclosure forming a sub space is arranged inside the housing at an upper part of the housing for trapping air when the liquid surface in the tank is inclined relative to the housing. An upper end of the enclosure is closed and airtight and a lower end of the enclosure is open connecting the space and the sub space fluidly to each other.

Abstract: One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.

Abstract: A method for detecting a contaminant in a vehicle coolant system during service includes contacting a chromophore impregnated strip and a heat transfer fluid sample, where the chromophore impregnated strip includes a complexing agent selected to form a complex with the contaminant that causes a color change in the chromophore impregnated strip and thereby indicates the presence of the contaminant in the heat transfer fluid sample.

Abstract: A vehicle includes a component coated with a pollutant reduction catalyst configured to remove pollutants from a flow of air over the component, a catalyst temperature sensor coupled to the component, a general temperature sensor, a vehicle speed sensor, and an active grille shutter (AGS) system having a plurality of movable grille shutters. A controller is configured to determine an efficiency of the pollutant reduction catalyst based on signals from the catalyst temperature sensor, the general temperature sensor, the vehicle speed sensor, and the AGS system.

Abstract: A controller for a vehicle executes a base temperature calculation process that calculates a base temperature of a component of the internal combustion engine, a correction value calculation process that calculates a correction value, a vehicle line reflection process when the vehicle including the component of which temperature is estimated is a temperature-estimated vehicle that is in a line of vehicles in order to reflect, on the correction value, a tendency of the component to be less cooled when the temperature-estimated vehicle is a trailing vehicle than when the temperature-estimated vehicle is a leading vehicle, a rearmost reflection process when the temperature-estimated vehicle is in the line of vehicles in order to reflect, on the correction value, a tendency of the component to be more cooled when the temperature-estimated vehicle is a rearmost vehicle, and a component temperature estimation process that corrects the base temperature with the correction value.

Abstract: A system is provided that may include a pressure sensor coupled to a radiator. The pressure sensor may determine plural pressure readings of a radiator fluid in the radiator. The system may also include a vehicle controller of a vehicle system that includes one or more processors. The one or more processors may repeatedly determine the plural pressure readings of the radiator fluid, and determine a pressure variance of the plural pressure readings that is repeatedly determined. The one or more processors may further be configured to identify a pressure condition based on the pressure variance that is determined.

Abstract: A warm-up method based on a temperature control module, a vehicle, and a storage medium. The warm-up method based on the temperature control module comprises: entering a cold start mode; obtaining current temperature control parameters, the temperature control parameters comprising a current water temperature value, a current engine speed, and a current engine load; obtaining working parameters of a temperature control module according to the temperature control parameters; controlling the temperature control module according to the working parameters to adjust the water temperature to warm an engine, and updating the current water temperature value; and after the updated current water temperature value does not exceed a warm-up threshold, returning to the step of obtaining the current temperature control parameters to enter the next cycle.

Abstract: An internal combustion system capable of exactly determining timing of exchanging a coolant of an engine. The internal combustion system includes an engine, cooling circulation mechanism circulating the coolant containing ethylene glycol to the engine while cooling it, temperature sensor measuring the temperature of the coolant having passed through the engine, and control device. The control device includes a number of cold starts counting unit determining engine cold start and counting the number of cold starts before coolant exchange, an accumulated amount of time measuring unit measuring an accumulated amount of time when the coolant temperature measured by the temperature sensor is a defined temperature or higher before the coolant exchange, and an exchange determination unit determining the need for coolant exchange, when the accumulated amount of time is a defined amount of time or greater and the number of cold starts is a defined number of times or greater.

Abstract: Methods and systems are provided for controlling operation of an engine of a vehicle to supply power to a power box that in turn supplies power to loads external to the vehicle. In one example, a method comprises, responsive to a request by an operator to operate an engine to power one or more loads external to the vehicle, monitoring an engine temperature and issuing an alert requesting the operator to take mitigating action to reduce the engine temperature when the engine temperature reaches a threshold temperature, and controlling a cooling fan as a function of whether or not the mitigating action is taken. In this way, fuel economy may be improved and power supply to power external loads may be optimized.

Abstract: Methods and systems for managing a monitoring of an engine cooling system. A transient condition associated with an engine system is identified. A determination is made as to whether the transient condition is a delay condition based on whether the transient condition exceeds a transient threshold. A determination is made, in response to a determination that the transient condition is not the delay condition, as to whether a period of time that has passed since a previously identified delay condition meets a time threshold. Monitoring of a health of the engine cooling system is enabled in response to a determination that the period of time meets the time threshold.
