Abstract
A method for establishing a permitted maximum differential pressure of an air filter arranged in an intake tract of an internal combustion engine is provided. The method includes determining a control reserve of the internal combustion engine and establishing the maximum permissible differential pressure of the air filter as a function of the determined control reserve.
Claims20
A method, comprising:
- determining a control reserve of an engine control of an internal combustion engine, wherein the engine control has a control range, a portion of the control range is used during normal operation of the internal combustion engine, and the control reserve comprises a remaining portion of the control range that is not intended to be used during normal operation of the internal combustion engine, wherein the control reserve decreases as a first portion of the control reserve is used to compensate for degradation of the internal combustion engine and a second portion of the control reserve is used to compensate for degradation of an air filter;
- and
- adjusting a maximum permitted differential pressure of the air filter in an intake tract of the internal combustion engine as a function of the decreased control reserve.
An internal combustion engine comprising:
- at least one air filter arranged in an intake tract of the internal combustion engine;
- and
- a controller configured to store a maximum permitted differential pressure for the at least one air filter;
- wherein the controller is configured to determine a control reserve of an engine control of the internal combustion engine and the maximum permitted differential pressure of the at least one air filter from measurement values of an at least one sensor and operating data of the internal combustion engine as a function of the determined control reserve;
- wherein the engine control has a control range, a portion of the control range is used during normal operation of the internal combustion engine, and the control reserve comprises a remaining portion of the control range that is not intended to be used during normal operation of the internal combustion engine, wherein the control reserve decreases as a first portion of the control reserve is used to compensate for degradation of the internal combustion engine and a second portion of the control reserve is used to compensate for degradation of the at least one air filter, and wherein the maximum permitted differential pressure is adjusted based on the decreased control reserve.

A method, comprising:
- determining a pressure difference across an air filter of an intake of an internal combustion engine as a function of a control reserve of an engine control of the internal combustion engine, wherein the engine control has a control range, a portion of the control range is used during normal operation of the internal combustion engine, and the control reserve comprises a remaining portion of the control range that does not have to be used during normal operation of the internal combustion engine, wherein the control reserve decreases as a first portion of the control reserve is used to compensate for degradation of the internal combustion engine and a second portion of the control reserve is used to compensate for degradation of the air filter.
