摘要： One embodiment of the present invention is an internal combustion engine system that includes an internal combustion engine, a turbocharger with a compressor and a turbine and a gas flow pathway defined therebetween, one or more pressure sensors to detect pressure along the gas flow pathway, an emission control device structured to receive exhaust from the turbocharger, and a controller responsive to input from the one or more pressure sensors. The controller determines a control signal indicative of turbine outlet temperature as a function of such input, and selectively generates an output signal to adjust temperature of the exhaust provided to the emission control device from the turbocharger in response to the control signal.

摘要： A method and system for controlling an exhaust temperature for an internal combustion engine is disclosed. The method and system comprise determining a range of acceptable charge flows within the internal combustion engine to meet a desired exhaust temperature. The method and system further comprise controlling the charge flows to fall within the range. Control strategies to utilize the charge flow as a lever to control turbine outlet temperature are disclosed. These strategies utilize the inversion of the cylinder outlet temperature virtual sensor as well as a new turbine outlet temperature virtual sensor to determine the charge flow required to achieve the desired turbine outlet temperature given the current turbine inlet and outlet pressure, SOI, charge pressure, charge temperature, fueling, and engine speed.

摘要： An apparatus and method for controlling exhaust gas recirculation flow. The apparatus and method uses a pressure-bleeding device, such as a wastegate valve, to change the pressure in an internal combustion engine in order to alter the flow rate of the exhaust gas through an exhaust gas recirculation conduit. In one form, the invention includes an inlet conduit connected to an intake manifold of an internal combustion engine and an exhaust conduit connected to exhaust manifold of an internal combustion engine. The pressure-bleeding device is operatively coupled to the intake conduit. Altering the pressure in the intake conduit changes the pressure across the entire system. This change in pressure in the entire system results in a change in pressure across the exhaust gas recirculation conduit. Therefore, a flow is created through the exhaust gas recirculation conduit and can be controlled using the intake side pressure bleeding device.

摘要： A variable geometry turbine and active wastegate are provided in combination along with independent control of the variable geometry turbine and wastegate valve so as to independently control exhaust gas recirculation flow and air flow in an internal combustion engine. Such independent control of exhaust gas recirculation flow and air flow in an internal combustion engine is achieved by providing a system for exhaust gas recirculation including an intake air manifold, an exhaust manifold, an exhaust gas recirculation passage providing fluid communication between the exhaust manifold and the intake air manifold, a variable geometry turbine positioned downstream of the exhaust manifold, and a waste gate passage providing fluid communication between the exhaust gas manifold and a point downstream of the variable geometry turbine. A control system is provided for controlling exhaust gas recirculation through the exhaust gas recirculation passage by independently controlling a geometry of the variable geometry turbine and thus the casing size of the turbine to control air flow and passage of exhaust gas through a waste gate passage in order to control compressor power which delivers the pressure ratio to the compressor and intake manifold. In doing so, both flow and power are independently controlled in order to maximize efficiency of the system.
