摘要： A system according to the principles of the present disclosure includes a transmission fluid temperature sensor and a coolant valve control module. The transmission fluid temperature sensor measures a temperature of transmission fluid that is circulated through a transmission. The coolant valve control module controls at least one coolant valve to adjust coolant flow from an engine to a transmission fluid heat exchanger and at least one of a radiator, an engine oil heat exchanger, and a heater core. When the transmission fluid temperature is less than a first temperature, the coolant valve control module controls the at least one coolant valve to allow coolant flow from the engine to the transmission fluid heat exchanger and prevent coolant flow from the engine to the at least one of the radiator, the engine oil heat exchanger, and the heater core.

摘要： A coolant control system of a vehicle includes a fraction module, and a coolant valve control module. The fraction module determines an oil fuel fraction based on an amount of fuel in an amount of engine oil. The coolant valve control module, based on the oil fuel fraction, selectively actuates a coolant valve to enable coolant flow from an integrated exhaust manifold (IEM) of an engine to an engine oil heat exchanger.

摘要： An exhaust gas treatment system for an internal combustion engine is provided. The exhaust gas treatment system includes an electrically heated catalyst (“EHC”) device in fluid communication with an exhaust gas conduit, a generator, a selective catalytic reduction (“SCR”) device, and a control module. The EHC device includes an electric heater and an EHC catalyst that is heated to an EHC light-off temperature. The generator is selectively operable in a target voltage mode to supply a target voltage to the electric heater. The target voltage represents a voltage required by the electric heater in order to maintain the EHC catalyst at a catalyst temperature. The SCR device is in fluid communication with the exhaust gas conduit. The SCR device is located downstream of the EHC device and includes an SCR catalyst that is selectively heated by the EHC device to a SCR light-off temperature.

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 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 method is disclosed for optimizing fuel economy during an engine warm up phase of operation of an internal combustion engine. An exhaust manifold may have a coolant jacket through which a coolant may flow. A temperature of the coolant in the exhaust manifold may be determined to detect when it is at a predetermined maximum threshold, which represents a temperature threshold just below a temperature at which the coolant will begin to boil. When this threshold is reached, then a determination may be made as to a minimum rate of flow of the coolant through the exhaust manifold which maintains the coolant at about the predetermined maximum threshold, and the coolant may be flowed through the exhaust manifold at the determined minimum rate of flow.

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.
