  • Systems and methods for controlling a combustion engine
    Patent number: 9157391
    Abstract: Some implementations of a system for controlling an internal combustion engine (e.g., a natural gas fired internal combustion engine or another type of engine) can include an air-fuel ratio controller that is configured to monitor sensor feedback from an exhaust path and to thereafter automatically adjust the air-fuel mixture. The system can be employed in particular methods to control emissions from the engine, for example, by reducing pollutants emitted as components of the exhaust from the engine.
    Type: Grant
    Filed: March 14, 2013
    Date of Patent: October 13, 2015
    Assignee: EMIT Technologies, Inc.
    Inventors: Samuel Brent Waggener, David Wayne Haile
