A method for controlling an operating mode of an engine including a turbocharger having a turbine and a compressor, and a control unit, the method comprising the steps of:
- determining the operating mode of the engine;
- receiving information from a user related to a user selected minimum boost pressure;
- determining a current boost pressure from a pressure sensor positioned downstream of the compressor of the turbocharger;
- comparing the current boost pressure with the user selected minimum boost pressure;
- and
- increasing the current boost pressure by providing a signal to the engine to increase the boost pressure if the current boost pressure is less than the user selected minimum boost pressure.
A method for controlling an engine including a turbocharger having a turbine and a compressor, the method comprising the steps of:
- providing an electronic control unit;
- and
- providing a control panel configured to allow a user to choose from at least one pre-configured boost pressure mode, the at least one pre-configured boost pressure mode being associated with a preselected minimum boost pressure and a preselected maximum boost pressure;
- determining an operating mode of the engine;
- receiving information related to the at least one boost pressure mode chosen by a user for input to the electronic control unit;
- determining a current boost pressure with a pressure sensor located downstream of the turbocharger compressor and inputting the current boost pressure to the electronic control unit;
- comparing the current boost pressure with the minimum boost pressure and the maximum boost pressure;
- and
- providing a signal to the engine to adjust operation of the engine so that the current boost pressure is always between the preselected minimum boost pressure and the preselected maximum boost pressure.
A system for controlling an engine equipped with a turbocharger having a turbine and a compressor, comprising:
- a first control system;
- wherein the first control system provides a user selected minimum boost pressure from a user to the control unit,
- a second control system;
- wherein the second control system includes at least one pre-configured boost mode with a predetermined maximum boost pressure and a predetermined minimum boost pressure available to a user wherein the user selects the at least one pre-configured boost mode;
- and wherein the control unit receives information related to the user's selection of the pre-configured boost mode;
- and
- an electric control unit,
- wherein the electronic control unit is configured to determine an operating mode of the engine;
- and to control the turbocharger such that a boost pressure downstream of the turbocharger compressor is maintained in accordance with the user selected minimum boost pressure or the pre-configured boost mode requested by the user.
