Abstract
Control of a turbocharger of a power system is disclosed. A controller may receive a desired value for a parameter of an engine. The controller may receive an operating value of the parameter. The controller may set, based on the desired value and the operating value, a position of an intake throttle valve of the engine to control air flow through a turbocharger of the engine.
Claims20
A method, comprising:
- determining a desired value for a parameter of an engine;
- determining an operating value of the parameter;
- determining that a difference between the desired value and the operating value is outside of a threshold range;
- and
- causing, based on the difference, a position of an intake throttle valve to be adjusted to control a rotational speed of a turbocharger of the engine to reduce the difference between the desired value and the operating value.
2 more elements
A device, comprising:
- a memory;
- and
- a processor, communicatively coupled to the memory, configured to:
- receive a desired value for a parameter of an engine;
- receive an operating value of the parameter;
- and
- set, based on the desired value and the operating value, a position of an intake throttle valve of the engine to control air flow through a turbocharger of the engine.
4 more elements
A power system comprising:
- an engine that includes:
- a turbocharger, and
- an intake throttle valve;
- a sensor system;
- and
- an electronic control module configured to:
- determine a desired value for a parameter of the engine;
- determine, based on a measurement from the sensor system, an operating value of the parameter;
- and
- control, based on the desired value and the operating value, a position of the intake throttle valve to control a rotational speed of the turbocharger.
