A system according to the present disclosure includes a start-stop module, a bypass valve control module, and a flapper valve control module. The start-stop module is configured to stop an engine of a vehicle independent of an ignition system of the vehicle. The bypass valve control module is configured to adjust a bypass valve to a bypass position to prevent engine coolant from flowing from the engine to a heater core of the vehicle when the engine is stopped independent of the ignition system. The flapper valve control module is configured to control a flapper valve to adjust an amount of airflow from an evaporator of the vehicle to a cabin of the vehicle through the heater core.

Methods and systems are provided for cooling an engine by operating an electrically driven intake air compressor. In one example, in response to a determination, based on a measured or inferred engine temperature, that the engine temperature is greater than a threshold temperature, employing the vehicle's electrically driven intake air compressor to route air through a charge air cooler and engine cylinders, while engine spins unfueled. In this way the engine temperature may be reduced even under conditions not normally amenable to engine cooling, such as at idle-stops or when an engine coolant system is degraded.

Provided is an internal combustion engine, comprising at least one cooling device for cooling at least one operational liquid of the internal combustion engine during and/or after operation of the internal combustion engine. The at least one cooling device has at least one heat exchanger and lines for transporting the at least one operational liquid to and from the at least one heat exchanger. The heat exchanger exchanges heat with a cooling medium, which cooling medium has during the operation of the internal combustion engine a lower temperature than the at least one operational liquid of the internal combustion engine. Heat is exchanged by the heat exchanger between the at least one operational liquid and the cooling medium, which cooling medium has before and/or during a starting operation of the internal combustion engine a higher temperature than the at least one operational liquid of the internal combustion engine.

A system and method for dissipating vehicle under hood heat accumulated during stationary engine operation at high load or RPM and/or under high temperature ambient conditions is installed in a vehicle having an engine positioned within an engine compartment, and a cooling fan selectively driven by way of a fan clutch. The system includes a controller connected to the engine and to the fan clutch. The controller determines whether the period of stationary engine operation occurs at or above a threshold engine load or RPM, at or above a threshold engine operating temperature, at or above a threshold ambient temperature, and/or for or longer than a threshold stationary engine operation duration. If so, the at least one controller increases a low idle set point of the engine and commands the fan clutch to engage or remain engaged for a cool-down period following the period of stationary engine operation.

A method for turbocharger key-off cooling control may include performing turbocharger key-off cooling control based on engine load for circulating engine coolant to a turbocharger cooling line when high cooling performance of a vehicle is checked by a coolant temperature and an oil temperature at which a turbocharger controller does not require operation of an auxiliary electric water pump when an engine is stopped.

A cooling system for a diesel engine. A surge tank defines a first coolant reservoir. A pump is operable when energized to drive a circulating flow of coolant through the diesel engine for cooling the diesel engine. A coolant channel is situated around a diesel exhaust fluid doser in an exhaust system extending from the diesel engine. A second coolant reservoir is positioned to maintain a dedicated gravity-fed coolant supply to the coolant channel situated around the diesel exhaust fluid doser when the pump is not energized. A vent line extends from the second coolant reservoir to the surge tank to allow venting from the coolant channel into the surge tank through the second coolant reservoir without evacuating liquid coolant from the coolant channel.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

A cooling device for an engine includes a radiator route passing through a radiator, that are merged together after being branched on the downstream side from the inside of the engine in a coolant circuit configured to allow a coolant to flow from a pump through the inside of the engine and return to the pump. An at-stop control section provided in the cooling device controls a multiway valve that has three discharge ports, including a radiator port connected to the radiator route, so as to close the radiator port and open at least one of the other discharge ports when an ignition switch is turned off.

A temperature control system for an engine. The system includes a thermal storage expansion tank defining a thermally insulated interior volume for storing engine coolant. The system further includes a pump that pumps engine coolant that has exited the thermal storage expansion tank back into the thermally insulated interior volume of the thermal storage expansion tank and forces air out of the thermal storage expansion tank to store coolant in the thermally insulated interior volume when the engine is off.
