摘要： The disclosure describes systems and methods of detecting a misfire in a cylinder of an engine. Such systems and methods may include determining a standard deviation for a crank angle location in a chamber of the engine, determining a standard deviation of the peak pressure in a chamber of the engine. If the standard deviation for a crank angle location is greater than a threshold value for the standard deviation for a crank angle, or if the standard deviation for the peak pressure is greater than a threshold value for the standard deviation of the peak pressure, an engine cylinder cut out check may be performed to identify one or more misfiring cylinders.

摘要： A method of operating an Exhaust Gas Recirculation (EGR) valve of an engine is provided. The method includes monitoring an operating condition of the engine based at least on a speed of the engine and a load of the engine. The method also includes determining an amount of Carbon Monoxide (CO) in an exhaust from the engine and comparing the amount of CO with a threshold CO value. The method further includes adjusting open loop parameters of the EGR valve based on the comparison during a predetermined operating condition for the engine. The EGR valve is controlled based on the open loop parameters during switching between a closed loop control and an open loop control of the EGR valve.

摘要： A system for controlling pressure of fuel supplied to an engine is disclosed. The system includes a pressure sensor to generate signals indicative of pressure of fuel at an outlet of a pressure regulator. The system includes a stepper motor coupled to a gear drive. The system includes a controller, in electric communication with the pressure sensor and the stepper motor, monitors the pressure of the fuel and determines an average pressure of the fuel at the outlet of the pressure regulator for a predefined cycle. The controller compares the determined average pressure with a threshold pressure and generates an output signal when the determined average pressure is beyond the threshold pressure. The controller further communicates the output signal with the stepper motor to preload the pressure regulator and controls the pressure of the fuel at the outlet of the pressure regulator.
