Abstract: A throttle body is provided with an internal fuel reservoir for relieving pressure waves and for assisting hot start conditions of an associated small internal combustion engine employing a low pressure fuel injection system.

Abstract: A keyboard joystick comprises a base having key actuating areas associated with the underside of the base. A control stick is mounted to the base to enable a user to actuate the arrow keys of a computer keyboard in conjunction with an associated computer game, for example.

Abstract: A low pressure, low cost electronic fuel injection system (18) for small hand-held two cycle engines (1) is provided which employs a number of improvements, including by way of example and not of limitation, an improved low cost injector construction (45), a throttle body integration (10) that includes mounting the operational components of the supply system on a single unit, an improved ignition module (40), a pressure regulated fuel system controlled by an electronic control unit (42) employing and an adaptive algorithm based on engine speed which controls the speed by varying the amount of fuel provided to the engine.

Abstract: A fuel injection system for a hydro carbon engine is provided with a simplified electronic governor system for controlling the maximum speed of the engine. The governor system is operatively associated with an electronic control unit (ECU) for operating the engine. A pulse width modulated fuel valve is provided with a pressure intensifier device enabling the fuel system to use low pressure signals in providing a fuel supply to the engine. The fuel system further is provided with a throttle body having the ECU, the fuel valve and the governor system integrated with on another in a single package for mounting on the engine.

Abstract: An apparatus and process for controlling an internal combustion engine (C) having an electronic fuel regulation system that provides fuel control for small engines (C) used in garden equipment (B) and small vehicles. An electronic control unit (1) accepts a plurality of signals generated by a plurality of sensors that detect certain environmental characteristics and certain engine operating characteristics. The electronic control unit (1) uses a set of firmware having a number of electronic maps to analyze the plurality of signals to manage operation of a fuel valve (3) and a fuel pump (2) to control the timing and amount of fuel delivered to the cylinder of small internal combustion engine (C) having at least one cylinder.

Abstract: A fuel regulator for two-cycle and/or four-cycle internal combustion engines, particularly those found in model airplanes, comprises a microprocessor, a thermocouple exhaust gas temperature sensor, and a fuel regulating valve installed in a low-pressure fuel delivery system between the fuel tank and the carburetor. During operation, the microprocessor continually receives signals from the exhaust gas temperature sensor. These signals are compared with stored temperature ranges to determine the optimum fuel mixture for the current engine operating conditions. If the current engine operating conditions require a variation in the fuel mixture setting, the microprocessor adjusts the degree of opening of the in-line fuel regulating value, and accordingly regulates the flow of fuel into the carburetor.
