Abstract
Systems and methods for operating an engine and controlling engine parameters over a range of ambient temperature conditions are provided. A method for an engine includes selecting one or more of an engine speed, an engine load, a base timing, and a fuel common rail pressure from a pre-calibrated engine map corresponding to a selected throttle level and modifying the one or more of the engine speed, the engine load, the base timing, and the fuel common rail pressure based on sensed environmental conditions.
Claims20
A method for operating an engine, the method comprising:
- obtaining one or more ambient environmental conditions;
- obtaining a desired throttle level for the engine;
- obtaining one or more determined engine operating parameters based at least in part on the desired throttle level and an engine operating map;
- and
- changing the one or more determined engine operating parameters obtained from the engine operating map based at least in part on the one or more ambient environmental conditions being outside of a defined threshold operating range of environmental conditions.
A system, comprising:
- an engine comprising a plurality of cylinders organized into two cylinder banks;
- one or more sensors;
- and
- a controller storing instructions in memory of the controller, the instructions executable to:
- obtain one or more ambient environmental conditions from the one or more sensors;
- obtain a desired throttle level for the engine;
- obtain one or more determined engine operating parameters based at least in part on the desired throttle level and an engine operating map;
- and
- change the one or more determined engine operating parameters obtained from the engine operating map based at least in part on the obtained one or more ambient environmental conditions being outside of a defined threshold operating range of environmental conditions.
