Abstract
A method for controlling an internal combustion engine includes receiving a request for a desired output from the internal combustion engine, receiving sensor information indicative of at least an engine speed or a pressure of gas provided to the internal combustion engine, and setting a changeable limit associated with a supply of air and fuel to the internal combustion engine. The method also includes, based at least in part on the received sensor information, changing the changeable limit to define a changed limit and reducing an output of the internal combustion engine based on the changed limit.
