摘要： The various embodiments of the present disclosure provide a device which comprises a controller 100 to determine the fuel pressure at a fuel injector 110. The controller 100 is adapted to measure a signal comprising load current 1082 drawn by the actuator against time. The controller 100 then processes the measured signal using a processing module 1062. A memory element 106 is either integral to the controller 100 or is externally connected to the controller 100. The controller 100 compares the output of the processing module 1062 with a pressure map 1064 stored in the memory element 106. The controller 100 then determines/estimates the fuel pressure of the fuel based on the comparison.

摘要： The various embodiments herein provide an Electronic Control Module (ECM) 102 to determine Air-Fuel (A/F) ratio of an engine 112. The ECM 102 is adapted to receive signals relating to engine operating parameters comprising at least one exhaust tem¬ perature, an engine speed, an engine load, an ignition angle and a relative fuel mass. The ECM 102 then accesses a global model, at least one weighing function and at least one data map from a memory element to determine the A/F ratio. The global model comprises at least two local models. The weighing function for each of the local model is used. The at least one data map comprises empirically derived values corre¬ sponding to the engine operating parameters. The ECM 102 processes the received signals of the engine operating parameters through the global model, the at least one weighing function and the data map and determines/predicts the A/F ratio.
