Title: SYSTEMS AND METHODS FOR PERFORMING ENGINE DE-RATE CONTROL OPERATION OF A VEHICLE
Abstract:
Methods and systems, using a controller (20), for performing de-rate operation of an engine (12) is disclosed. Controller (20) includes a de-rate condition detection unit (204), an operational parameter adjustment unit (206), and a de-rate condition monitoring unit (208). De-rate condition detection unit (204) detects a low fuel condition based on a current delivery pressure level of the engine (12) detected at least one of: in a fuel tank (24) and along an inlet fuel rail (38) connecting the fuel tank (24) to the engine (12). Operational parameter adjustment unit (206) performs the de-rate operation on the engine (12) by adjusting one or more operational parameters related to an engine (12) load based on the detected low fuel condition. De-rate condition monitoring unit (208) monitors the detected low fuel condition for a predetermined time period in response to the operational parameter adjustment performed by operational parameter adjustment unit (206).
