System and method for remotely monitoring a turbocharged engine

A method for remotely monitoring operation of a multicylinder, turbocharged reciprocating engine, comprising:

• determining the rotational speed of the turbocharger with a speed detection system generating a speed signal corresponding to said rotational speed;
• determining the actual flow rate of charge air through the engine's cylinders with a flow detection system generating an airflow signal corresponding to said flow rate;
• transmitting the speed signal and the airflow signal to a remote monitoring center via telemetry;
• comparing the actual charge air flow rate with a predetermined flow rate corresponding to the turbocharger's rotational speed, with a controller receiving said speed signal and said airflow signal, wherein said predetermined flow rate is based upon a trend analysis, stored within said controller, of the rotational speeds and corresponding mass flow rates for said engine;
• and
• setting a charge air condition flag indicating that a charge air leak or restriction exists downstream of the turbocharger if the actual charge air flow rate is less than the predetermined flow rate.

A method for remotely monitoring the operation of a multicylinder, turbocharged reciprocating engine, comprising:

• monitoring at least one operating parameter predictive of the turbocharger's output and generating a parametric output signal corresponding to the value of said at least one operating parameter;
• determining the actual mass flow rate of charge air through the engine's cylinders with a flow detection system, and generating an airflow signal corresponding to said flow rate;
• transmitting the parametric output signal and the airflow signal to a remote monitoring center via telemetry;
• comparing the actual charge air flow rate with a predetermined flow rate corresponding to said monitored operating parameter at said remote monitoring center, with a controller receiving said parametric output signal and said airflow signal, wherein said predetermined flow rate is based upon a trend analysis, stored within said controller, of said operating parameter and corresponding mass flow rates for said engine;
• and
• setting a condition flag if the actual charge air flow rate is less than the predetermined flow rate.
