    摘要： A method of diagnosing operation of a turbo speed sensor that monitors a turbocharger in an internal combustion engine system includes determining whether the engine system is operating in one of a high speed and a low speed range and determining a threshold turbo speed value based on whether engine system is operating in one of the high speed and the low speed range. An actual turbo speed value of the turbocharger is monitored based on a signal generated by the turbo speed sensor. The actual turbo speed value is compared to the threshold turbo speed value and a diagnostic signal is generated based on the step of comparing.

    摘要： The present invention relates to the identification of a specific cysteine (Cys) residue in MgrA of Staphylococcus aureus and homologs in other bacteria that acts as a redox switch to regulate virulence of S. aureus and expression of bacterial genes that confer resistance to antibiotics. In addition, MgrA is found to be a key virulence determinant for S. aureus. Oxidative regulation of other Cys containing proteins in various bacteria has been observed, leading to the ability to modulate virulence and resistance of these organisms.

    摘要： A diesel oxidation catalyst (DOC) testing system includes a DOC that is located in an exhaust system of a vehicle. A control module verifies proper operation of the DOC during a post-fuel injection process in an engine of the vehicle. The control module computes a predicted temperature of exhaust gases at an output of the DOC that corresponds with proper operation of the DOC during the post-fuel injection process, determines an actual temperature of the exhaust gases during the post-fuel injection process, and activates an alarm indicator when a difference between the predicted temperature and the actual temperature is greater than a first predetermined value. A first temperature sensor is located downstream from the DOC in the exhaust system. The first temperature sensor communicates with the control module, generates the actual temperature, and transmits the actual temperature to the control module.

    摘要： An equivalence ratio-based system for controlling transient engine fueling includes an engine controller responsive to a number of engine operating conditions to estimate a mass of oxygen trapped within a number of cylinders of an internal combustion engine. The engine controller is further operable to map current values of engine speed and commanded fueling to one of a number of predetermined maximum fuel-to-oxygen, or equivalence, ratio values (&PHgr;MAX). The engine controller is then operable to determine an oxygen/fuel control (OFC) limited fueling command (FOFCL) as a function of the estimated oxygen mass value and the maximum equivalence ratio, and to limit engine fueling based on the OFC limited fueling command FOFCL. In one embodiment, the engine controller is operable to fuel the engine according to a minimum of the OFC limited fueling command FOFCL and a default fueling command FDEF, although other fuel limiting strategies are contemplated.
