摘要： A system for controlling fluid temperature includes a heat source, a heat sink coupled to the heat source such that a flow of coolant passes between the heat source and the heat sink, a first heat exchanger coupled to the heat source, a second heat exchanger coupled to the heat source, a valve coupled to the heat source, the first heat exchanger, the second heat exchanger, and the heat sink, the valve configured to regulate the flow of coolant between the heat source, the first heat exchanger, the second heat exchanger, and the heat sink, and a controller in electronic communication with the heat source and the valve. The controller is configured to determine an operating condition and generate a control signal to control the valve to direct the flow of coolant to one or more of the first and second heat exchangers and the heat source.

摘要： A vehicle powertrain thermal management system for distributing thermal energy to vehicle powertrain components, including an engine and a transmission. The system for managing heat energy includes a coolant pump, a first control valve, a second control valve, a radiator, a heater core, and a transmission oil heat exchanger. The first control valve has an inlet that is in fluid communication with the engine coolant outlet. The first control valve also has a first control valve outlet. The second control valve has a first inlet, a second inlet, a first outlet, a second outlet and a third outlet. Heat energy produced by the engine is transferred to the radiator through control of the first control valve and to at least one of the heater core, and the transmission oil heat exchanger through the control of the second control valve.

摘要： A control system according to the principles of the present disclosure includes an estimated coolant flow module and at least one of a valve control module and a pump control module. The estimated coolant flow module estimates a rate of coolant flow through a cooling system for an engine based on a pressure of coolant in the cooling system and a speed of a coolant pump that circulates coolant through the cooling system. The valve control module controls the position of a coolant valve based on the estimated coolant flow rate. The pump control module controls the coolant pump speed based on the estimated coolant flow rate.

摘要： A method of treating an exhaust gas produced by a vehicle internal combustion engine includes conveying the gas through a first reactor including a non-thermal plasma. The gas includes nitric oxide and is transitionable between a first condition in which the gas has a cold-start temperature that is less than or equal to about 150° C., and a second condition in which the gas has an operating temperature that is greater than about 150° C. During the first condition, the method includes contacting the gas and plasma to oxidize the nitric oxide to nitrogen dioxide and form an effluent that includes nitrogen dioxide. The method includes concurrently conveying the effluent through a second reactor including a diesel oxidation catalyst, and storing the nitrogen dioxide within the second reactor during only the first condition. The method includes, after storing, releasing nitrogen dioxide from the second reactor during only the second condition.

摘要： A method for controlling regeneration within an after-treatment component of an engine comprises receiving a signal indicative of whether the engine is in an operating state or a non-operating state and detecting, based on the signal, when the engine has departed an operating state and entered a non-operating state. When the engine has departed an operating state and entered a non-operating state, a regeneration event is initiated. The regeneration event comprises causing a stream of air to flow through the after-treatment component and initiating a flow of fuel into the stream of air.

摘要： A method is applied to regenerate particulate matter in a particulate filter of a hybrid electric vehicle having a combination of a combustion engine and an electric motor for propelling the vehicle, the hybrid electric vehicle having an electrically heated catalyst disposed in flow communication with the particulate filter in an exhaust system of the vehicle. The method determines whether the combustion engine is or is not combusting fuel, and under a condition where the combustion engine is not combusting fuel, the catalyst is electrically heated until it has reached a temperature suitable to cause ignition of the particulate matter. The electric motor is used to facilitate rotation of the combustion engine at a rotational speed suitable to draw air into and be exhausted out of the combustion engine into the exhaust system, across the catalyst, and into the particulate filter to facilitate ignition of the particulate in the filter.

摘要： A method for coolant pump flow rationalization using coolant pump parameters includes calculating a first pump coolant flow based on a coolant input pressure sensor signal and the coolant pump speed. Further, the method includes calculating a second pump coolant flow based on coolant pump current and coolant pump speed when the first pump coolant flow is greater than a predetermined threshold; and comparing the first pump coolant flow with the second pump coolant flow to rationalize the coolant pressure sensor signal.

摘要： A vehicle thermal management system includes a radiator receiving a liquid coolant in a coolant supply line and discharging the coolant into a coolant pump supply line. A coolant pump receives the coolant from the coolant pump supply line and discharges the coolant into multiple engine components. A transmission oil heat exchanger defining a first transmission oil heat exchanger receives the coolant after being discharged from the multiple engine components. An air-to-coolant sub-cooling heat exchanger defines a second transmission oil heat exchanger. The sub-cooling heat exchanger receives a portion of the coolant bypassing the multiple engine components.
