摘要:
A diagnostic system with a single diagnostic protocol server and multiple data source modules for an electronically controlled internal combustion engine.
摘要:
A fault code memory manager architecture for heavy duty diesel engines consisting of a dedicated monitoring unit module and at least one fault code memory manager administrator module.
摘要:
A method and computer readable medium are disclosed to control operation of an internal combustion engine having an electronic control unit (ECU) with memory to burn off HC in an engine exhaust system and limit hydrocarbon and NOx content in the engine exhaust stream while operating the engine in idle mode.
摘要:
A method to operate a vehicle equipped an internal combustion engine and a transmission coupled to drive wheels. The vehicle is equipped with a parking brake and has an electronic control unit with memory and the engine in fluid communication with an exhaust aftertreatment system. The method includes the steps of determining whether the engine is operating in idle mode for a predetermined period of time; determining whether NOx emissions exceed a predetermined level after the predetermined period of time; and limiting the engine speed not to exceed a predetermined engine speed until an operator engages the parking brake and engages an engine ignition switch.
