  • Publication number: 20090055072
    Abstract: 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.

  • Patent number: 7302335
    Abstract: A mass airflow sensor measurement correction system for a turbocharged diesel engine operating under transient conditions includes a signal input device that generates an engine speed signal based on an engine speed of a turbocharged diesel engine. A control module receives the engine speed signal and calculates a correction value of mass airflow from a differential of the engine speed signal and a constant.
