| Summary / Description | The location-sensitive engine control system includes position locating system (PLS) interfacing with control logic which in turn interfaces with an engine control. Location coordinates from the PLS are relayed to the control logic and compared to an emissions map to determine the emission requirements and corresponding engine control settings. The engine control receives the engine control settings from the control logic and adjusts engine parameters to allow the engine to comply with the emission requirements. If desired, emissions information may be stored in the control logic. |

Excerpt The location-sensitive engine control system includes position locating system (PLS) interfacing with control logic which in turn interfaces with an engine control. Location coordinates from the PLS are relayed to the control logic and compared to an emissions map to determine the emission requirements and corresponding engine control settings. The engine control receives the engine control settings from the control logic and adjusts engine parameters to allow the engine to comply with the emission requirements. If desired, emissions information may be stored in the control logic. An antenna or other suitable device for receiving and transmitting information may interface with the control logic to provide emissions map updates and to allow transmission of the emissions information. |
A system for monitoring and controlling locomotive engine emissions comprising:
a location determination unit for determining a geographic location of a locomotive;
memory for storing a plurality of predetermined engine emission profiles, one profile for each of a plurality of geographic locations;
a processor in communication with the memory for accessing the engine emission profile for the determined location of the locomotive and generating an engine control command responsive to respective engine emission profile and engine operating parameters;
a control unit on board the locomotive controlling an operation of the locomotive responsive to the engine control command to limit the production of engine emissions to the corresponding emission profile;
a monitor unit monitoring values of an emission parameter of the locomotive indicative of the emissions produced by the engine; and
memory storing the values of the emission parameter of the locomotive and at least one of the time and the location of the locomotive when the engine emission was monitored.
| Relevance | The location determination similar to the position locating system (Claim 1) |
The system of claim 1, wherein the monitor unit comprises a sensor selected from the group consisting of an engine inlet air temperature sensor, a fuel injection timing sensor, a fuel injection pressure sensor, and a sensor sensing engine exhaust characteristics.
