Abstract
An engine system is disclosed that monitors for boost leak. The system has an engine, a compressor located upstream of the engine, at least one auxiliary flow device located downstream of the engine, and a computing system operable to determine an estimated value corresponding to a flow of fluid through the compressor. The estimated value takes into account a flow of fluid from the compressor toward the at least one auxiliary flow device distinct from a flow from the compressor toward the engine.
Claims21
A method for monitoring boost leak in an internal combustion engine system, comprising:
- providing a first flow of fluid from a compressor toward at least one auxiliary flow device;
- providing a second flow of fluid from the compressor toward an engine of the internal combustion engine system, the second flow of fluid distinct from the first flow of fluid;
- and
- determining an estimated value corresponding to a flow of fluid through the compressor, the estimated value being determined as a function of the first flow of fluid from the compressor toward the at least one auxiliary flow device.
An internal combustion engine system, comprising:
- an engine;
- a compressor located upstream of the engine;
- at least one auxiliary flow device located downstream of the engine;
- and
- a computing system operable to determine an estimated value corresponding to a flow of fluid through the compressor, the estimated value being determined as a function of a flow of fluid from the compressor toward the at least one auxiliary flow device distinct from a flow of fluid from the compressor toward the engine.
A method for monitoring boost leak in an internal combustion engine system, comprising:
- providing compressed fluid from a compressor to at least one first device;
- providing compressed fluid from the compressor to at least one second device, the at least one second device being different from the at least one first device;
- generating a response indicating a boost leak, wherein whether or not a response is generated is a function of an amount of compressed fluid provided to the at least one second device.
A system for monitoring boost leak in a compressor system, comprising:
- a first device;
- a compressor located upstream of the first device;
- at least one second device located downstream of the first device;
- and
- a computing system operable to determine an estimated value corresponding to a flow of fluid through the compressor, the estimated value being determined as a function of a flow of fluid from the compressor toward the at least one second device distinct from a flow of fluid from the compressor toward the first device.
