Patent number: 11339732Abstract: A turbocharger control method and related systems are provided. An operational command to control a level of boost provided by the turbocharger is received. In response to receiving the operational command, an exhaust gas recirculation (EGR) valve is instructed to move from a current position to a desired position. A time taken for the EGR valve to move from the current position to the desired position is determined. A maximum rise rate of exhaust manifold pressure corresponding to a predicted EGR valve position is determined. A permitted exhaust manifold pressure limit for the turbocharger is determined based on a current exhaust manifold pressure, the maximum rise rate of exhaust manifold pressure and the time taken. An operation of the turbocharger is controlled such that the permitted exhaust manifold pressure limit is not exceeded.Type: GrantFiled: February 9, 2021Date of Patent: May 24, 2022Assignee: Ford Global Technologies, LLCInventors: Jon Dixon, Andres Arevalo

Patent number: 10895207Abstract: A method of operating an engine assembly is provided. The engine assembly comprises an engine and a turbocharger assembly, wherein a control parameter of the turbocharger assembly is controllable in order to control a level of boost provided by the turbocharger assembly. The method comprises determining a desirable pressure limit of exhaust gases upstream of a turbine of the turbocharger assembly, predicting a desirable limit value of the control parameter to be applied to the turbocharger assembly in order to achieve the desirable pressure limit, determining an error in the desirable limit value of the control parameter, adjusting the desirable limit value of the control parameter based on the error, and controlling the operation of the turbocharger assembly such that the adjusted limit value is not exceeded.Type: GrantFiled: December 17, 2018Date of Patent: January 19, 2021Assignee: Ford Global Technologies, LLCInventors: Jon Dixon, Nicholas Michael Parisi, Jeffrey B.

Patent number: 10408171Abstract: A method of cleaning an EGR valve operatively connected to an exhaust flow from an engine includes determining when cleaning is required, and when cleaning is required, operating the engine in a high temperature mode in which the temperature of exhaust gas exiting the engine is increased while producing a flow of exhaust gas having a low unburnt hydrocarbon content. The method further includes opening the EGR valve to allow hot exhaust gas to flow therethrough so as to remove combustion by-products that are fouling the EGR valve. Furthermore, the method includes producing an estimate of accumulated combustion by-product fouling of the EGR valve. The estimate is then used to determine whether and when to clean the EGR valve.Type: GrantFiled: October 27, 2017Date of Patent: September 10, 2019Assignee: Ford Global Technologies, LLCInventors: Jon Dixon, Jim Bromham, Sean Gordon Harman
