    摘要: The invention comprises a method and an article of manufacture to estimate exhaust gas temperature of an internal combustion engine during ongoing operation of the engine. This comprises determining states of a plurality of parameters of a combustion charge. A heat release of the combustion charge is estimated based thereon, and an exhaust gas temperature is estimated based upon the estimated heat release. Exemplary parameters of the combustion charge comprise engine speed, mass air flowrate, engine fueling and fuel injection timing, and, recirculated exhaust gas fraction.

    摘要: An air intake system for an internal combustion engine includes a manifold defining a chamber in which air is distributed to a plurality of engine cylinders. The chamber includes an inlet and a plurality of outlets, each outlet providing fluid communication between the chamber and an engine cylinder. Each of the plurality of outlets is substantially the same distance from the inlet to provide more consistent gas flow rates through the outlets. The air intake system preferably includes a plurality of runners. Each of the plurality of runners defines a passageway that interconnects one of the outlets to a respective engine cylinder. Each passageway is characterized by the same length and the same cross sectional area.

    摘要: Methods and systems for detecting faults in temperature sensors on engine systems provided with equipment for treatment of combustion products of an exhaust effluent stream during engine operation include determining sensor faults from differences in temperature between sensors present in such systems over time. Estimated exhaust gas temperatures may be compared against real time temperature measurements to arrive at a diagnostic residual value representing the difference between a modeled value and measured value, and deviation of the measured value from the modeled value is used to indicate a sensor fault.
