Fuel-management systems are used to maintain, control and monitor fuel consumption and stock in any type of industry that uses transport, including rail, road, water and air, as a means of business. Fuel-management systems are designed to effectively measure and manage the use of fuel within the transportation and construction industries. They are typically used for fleets of vehicles, including railway vehicles and aircraft, as well as any vehicle that requires fuel to operate. They employ various methods and technologies to monitor and track fuel inventories, fuel purchases and fuel dispensed. This information can be then stored in computerized systems and reports generated with data to inform management practices. Online fuel management is provided through the use of web portals to provide detailed fueling data, usually vis a vis the back end of an automated fuel-management system. This enables consumption control, cost analysis and tax accounting for fuel purchases.

Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and / or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

Water Based Systems for Direct Injection Knock Prevention in Spark Ignition Engines
InactiveUS20100121559A1Minimizing and eliminating misfiringLiquid separation auxillary apparatusInternal combustion piston enginesWater basedAlcohol
A fuel management system for using water for on-board vehicular separation of ethanol from ethanol-gasoline blends is described. Water or a water-alcohol mixture from a secondary tank is mixed with the ethanol-gasoline blend resulting in separation of the ethanol. By using on-board vehicular separation, the consumption of the externally supplied liquid from a secondary tank can be decreased to less than 1% of the gasoline consumption. This allows for long refilling periods for the externally supplied fluid. In another embodiment, a water-based fluid is directly injected into the cylinders of a spark ignition engine to eliminate knocking without causing misfire. In a further embodiment, an alcohol-based fluid is also used in those circumstances where injection of the water-based fluid may cause misfire.

An enterprise fuel management system for managing fueling operations of an aircraft fleet operated by a fleet operator having a central computer system at a data center and operating aircraft at multiple airports avoids reliability problems associated with synchronizing a central database with local databases. Data collection units communicate collected fueling information wirelessly to a central data center, and the data collection units are not in direct communication with the fleet operator's central computer system. Moreover, the central data center gathers fueling information from the various data collection units and communicates the gathered fueling information to the fleet operator's central computer system as data messages for subsequent processing and action. In this way, the fleet operator's central computer system can maintain the only database of fueling information and flight information, obviating the need to synchronize the data in the fleet operator's computer system with data in some other computer system.
