A self-tuning fuel injection system and method having a first long-term fuel trim correction algorithm to selectively replace an operating zone within a volumetric efficiency look-up table based with a proposed correction only if mathematical comparisons with a surrounding determinative zone reveal that the correction will not result in an abrupt discontinuity. Mathematical comparison models may include absolute values of the differences or percent differences of each proposed cell and its neighbors, the difference of each proposed cell and the mean of its eight neighbors, and standard deviation of each proposed cell and its neighbors. A second repair algorithm repairs values surrounding an operating zone that have such a dissimilar magnitude as to cause poor engine performance using linear interpolation, for example. According to the invention, either the correction or the repair algorithm, or both, are executed in series or in parallel.

A throttle body fuel injection system and method that is arranged to easily replace four-barrel carburetors includes a throttle body assembly with four main bores, each with a throttle plate and an associated fuel injector. Each injector feeds fuel into a circular fuel distribution ring via a fuel injection conduit, which introduces pressurized fuel into the air stream. The fuel distribution rings and bores have profiles that avoid constrictions for to prevent low pressure zones according to the Venturi effect. The throttle body includes an idle air control circuit having a port opening into main intake bores downstream of the point of fuel distribution into the air stream, thereby reducing the tendency for a lean fuel mixture at idle. An ECU “feed forward” algorithm controls fuel injection as a function of the position of the idle air control valve.

A method and apparatus for providing portable ground power for aircraft. A ground power unit includes a lithium ion cell battery assembly and a standard three-pin aircraft ground power connector integrated into a single unit and packaged inside a ruggedized plastic housing with a carry handle, thereby eliminating the heavy and bulky power cables between the battery and connector. A battery management unit sets charge/discharge limits and provides monitoring of state of charge, health, and function. A charging connector and charging circuitry with user-selectable regulated charging limits allows simultaneous charging and discharging operations and connection into aircraft auxiliary circuits. A ganging station is provided to electrically combine the outputs of several ground power units in parallel for starting larger aircraft.

A method for cooling an ECU and an ECU or ECU module mounted to be cooled by fuel flow through a fuel rail. In a preferred embodiment, the ECU has a decentralized distributed processing configuration, with a main ECU module and at least one remote module. The remote ECU module is packaged in an assembly with an elongate hollow metal fuel rail having injector seats. Fuel injectors are received into and seal against the seats and are supplied with fuel via the fuel rail. A printed circuit board carries electronic ECU components. One or more connector assemblies are connected to printed circuit board for electrically connecting the ECU circuitry and may pass through notches formed in the fuel rail. The electronics are potted and mounted to the fuel rail. A thermally conductive wetting compound may be disposed between the electronic assembly and the fuel rail.
