  • Diesel exhaust system and method for controlling exhaust fluid dosing
    Patent number: 9453449
    Abstract: A method for controlling dosing of a diesel exhaust fluid includes providing a diesel engine and an exhaust system. The exhaust system includes an exhaust aftertreatment device and is coupled to the diesel engine. An injection device is provided in the exhaust system for dosing the diesel exhaust fluid into the exhaust system according to a predetermined routine. A water condensation content of the exhaust aftertreatment device is determined. A dosing event, directed by the predetermined routine, is precluded so that the injection device is not operated to provide diesel exhaust fluid to the exhaust aftertreatment device when the water condensation content of the exhaust aftertreatment device is determined to be above a specified threshold value.

  • Controller and control method for an engine control unit
    Patent number: 7497205
    Abstract: The invention provides a controller for determining the presence of faults within a fuel injection system of an engine system. The engine system comprises a first injector and at least one further injector, each injector comprising a needle control valve and a pressure control valve. The controller comprises: inputs for receiving data relating to a first engine system parameter; outputs for outputting a control function for controlling the injector valves of each of the injectors, and; a processor for controlling the control function output from the controller.
