Abstract: A signal generator provides a non-linear fuel-control output signal, in response to an analog input-voltage signal which is linearly related to throttle setting. A multi-step switch divides into equal increments the full range of possible throttle-setting signals, and, in conjunction with a resistor network, provides a stepped output, the progression of which is a non-linear function of throttle setting. A dither circuit produces an oscillating sawtooth voltage of amplitude scaled to a one-step increment, and addition of this voltage to the throttle-setting voltage is effective to produce a smooth and effectively continuous non-linear output of the resistor network. A smoothing circuit at output of the resistor network yields a d-c output which is non-linearly related to the throttle setting . Non-linearity can be designed to various requirements merely by selection of component values in the resistor network, without change of the switch and without modifying or adjusting any of the componentry for input-signal supply to the switch.

Abstract: A system for inhibiting marine organism growth on underwater surfaces provides an electric current generator which causes an electric current to flow proximate the underwater surface. A source of power, such as a battery, provides electrical power to the electric current generator. The flow of current passes from the underwater surface through water surrounding the surface or in contact with the surface, and a point of ground potential. The point of ground potential can be a marine propulsion system attached to a boat on which the underwater surface is contained.

Abstract: A feedback fuel metering control system is provided for an internal combustion engine and eliminates the need for high pressure fuel injectors, a high pressure fuel pump and a constant fuel pressure regulator. The system senses the amount of combustion air supplied to the engine, senses fuel flow velocity, and controls the amount of fuel supplied according to the amount of combustion air and the fuel flow velocity.

Abstract: A mass flow fuel injection control system is provided for an internal combustion engine and measures mass and flow velocity of combustion air. The length of fuel injection pulses is determined by 2ROOT PDPA/T, where PD is the air pressure drop produced by a venturi (32), PA is absolute air pressure, and T is air temperature. The system directly determines fuel requirements from the air mass flow and automatically self-adjusts and tracks such requirements from engine to engine or with modifications to the engine, without a preprogrammed look-up table according to throttle setting, and eliminates the need for a throttle position sensor.

Abstract: TWO-CYCLE ENGINE WITH FUEL INJECTION The invention contemplates electronically controlled fuel-injection for a multiple-cylinder two-cycle internal-combustion engine wherein each cylinder has its own independent crankcase region in which to receive and compress inlet air and fuel, prior to delivery of combustible mixture to the head or combustion end of the cylinder. Fuel is injected into each crankcase region during only a portion of the stroke involving induced intake of air therein, i.e., during only a portion of the rise of each piston in its approach to top-center position, and while pressure within the crankcase region is relatively uniform. The time-duration of actual injection is relatively short, thus enabling a plurality of different cylinder injections to be made concurrently, resulting in simplification of fuelinjection control circuitry.

Abstract: A system for inhibiting marine organism growth on underwater surfaces (16,50,52) provides an electric current generator (54) which causes an electric current to flow proximate the underwater surface. A source of power (P1), such as a battery, provides electrical power to the electric current generator (54). The flow of current passes from the underwater surface (16,50,52) through water surrounding the surface or in contact with the surface, and a point of ground potential. The point of ground potential can be a marine propulsion system attached to a boat on which the underwater surface is contained.

Abstract: An auxiliary fuel supply system is provided for a two cycle internal combustion engine (302). A first fuel line (350) supplies fuel from the fuel pump (338) to a solenoid (352) which is continuously cyclable between ON and OFF states during running of the engine, includig high speed operation where detonation may occur. Fuel then flows through a second fuel line (354) to a restriction orifice metering housing (356), and then to a plurality of third branch fuel lines (358, 384, 386, 388, 390 and 392) for delivery to respective cylinders. The restriction orifices provide a pressure drop from the second fuel line to the plurality of third fuel lines, to provide lower fuel pressure in the third fuel lines, to reduce the chance of leakage at the intake manifold (326), and also to reduce fuel pressure fluctuations in the third fuel lines otherwise due to cycling of the solenoid. Metering housing structure is disclosed. The solenoid is controlled by a variable duty cycle oscillator (408), which in turn is controlled by a fuel enrichment signal (84) output by an electronic control which is responsive to engine knock and/or temperature. Control circuitry is disclosed.
