Adjusting Engine Timing Based On Geo -
In traditional fuel sourced engines, fuel consumption and operational performance is directly influenced by engine timing of a vehicle. Generally, the engine timing is controlled using onboard computing technology. Altitude significantly impacts the fuel consumption and operational performance of an internal combustion engine in the vehicle. For example, a vehicle operating at higher altitude (e.g., 10,000 feet above the sea level) needs to force more air into the combustion chamber to generate more power, which leads to higher fuel consumption.
Disclosed is a method and system for adjusting engine timing based on geo-location of a vehicle. The method and system improves performance of a computer controlled vehicle based Global Positioning System (GPS) data, which provides the geo-location of the vehicle.
The method and system utilizes GPS data to determine a current altitude of the vehicle. Onboard computing algorithms are modified to occasionally query the GPS data using onboard communications. The occasional querying of the GPS data enables the system to determine the vehicle location and associated altitude.
The GPS data thus obtained is transmitted to an onboard computing resource to influence engine timing which impacts engine performance. Specifically, the altitude information is used to change the engine time dynamically to either advance or retard the timing of the electric spark needed to ignite a cylinder of the...
