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.

대표청구항 ▼

1. A system for controlling a combustion engine, comprising: a catalyst reaction device configured to mount along an exhaust path of an engine, the catalyst reaction device including one or more catalyst reaction cartridges configured to reduce an amount of pollutants emitted from the catalyst reaction device;a pre-catalyst exhaust sensor configured to be mounted along the exhaust path before the one or more catalyst reaction cartridges;a post-catalyst exhaust sensor configured to be mounted along the exhaust path after the one or more catalyst reaction cartridges; andan air-fuel ratio controller configured to output a control signal to a fuel valve for controlling an air-fuel mixture input into the engine, the air-fuel ratio controller being communicatively connectable to the pre-catalyst exhaust sensor and the post-catalyst exhaust sensor, wherein the air-fuel ratio controller is configured to output the control signal to the fuel valve to increase a fuel level in the air-fuel mixture in response to the signal received from the post-catalyst exhaust sensor switching from a high signal to a low signal during a period when the signal received from the pre-catalyst exhaust sensor is continuously maintained as a high signal. 2. The system of claim 1, wherein the air-fuel ratio controller is configured to increase the fuel level in the air-fuel mixture after expiration of a constant-value lean timer that begins in response to the controller detecting the signal received from the post-catalyst exhaust sensor switching from the high signal to the low signal. 3. The system of claim 1, wherein the air-fuel ratio controller comprises a user interface display device, and wherein the air-fuel ratio controller configured to control an air-fuel mixture input into a stationary natural gas fired or propane fired internal combustion engine. 4. The system of claim 2, wherein the air-fuel ratio controller is configured to decrease the fuel level in the air-fuel mixture after expiration of a constant-value rich timer that begins in response to the controller detecting the signal received from the post-catalyst exhaust sensor switching from the low signal to the high signal. 5. The system of claim 4, wherein the constant-value rich timer is always greater than the constant-value lean timer. 6. The system of claim 4, wherein a magnitude of the constant-value rich timer is user selectable via a user interface device of the air-fuel ratio controller.
