Abstract: An independent radial vane rotary machine for the production of rotary mechanical power through internal combustion of liquid or gaseous fuel and employing intermeshed gearing for synchronization of major rotational components. The machine functions in general accordance with the principles of the Carnot heat engine cycle but mechanical manipulation of working fluid is accomplished without reciprocating mechanical components and combustion is performed as a continuously sustained process. The machine offers vibration-free operation and good measures of functional efficiency, power density, and inherent reliability. The disclosure presents the geometric and mechanical features necessary to demonstrate functional viability.

Abstract: During a combustion cycle, a first stoichiometrically lean fuel charge is injected well prior to top dead center, preferably during the intake stroke. This first fuel charge is substantially mixed with the combustion chamber air during subsequent motion of the piston towards top dead center. A subsequent fuel charge is then injected prior to top dead center to create a stratified, locally richer mixture (but still leaner than stoichiometric) within the combustion chamber. The locally rich region within the combustion chamber has sufficient fuel density to autoignite, and its self-ignition serves to activate ignition for the lean mixture existing within the remainder of the combustion chamber. Because the mixture within the combustion chamber is overall premixed and relatively lean, NOx and soot production are significantly diminished.

Abstract: An injection quantity control system for an internal combustion engine stores a value Qb, which is a sum of an FCCB correction value and an ISC correction value corresponding to an injection frequency of K times per combustion in multi-injection in an idling stabile state of the engine. The system stores a value Qc, which is a sum of the FCCB correction value and the ISC correction value corresponding to the injection frequency of N times. Based on a difference between the values Qb and Qc, a final learning value (Q1/K or Q1/N) is calculated. Thus, an injector individual difference, an inter-cylinder injection quantity variation, and an injector aging deterioration quantity can be discriminated from an increase in an engine-demanded injection quantity due to an engine load factor.

Abstract: In a fuel system of an internal combustion engine, a fuel pressure sensor is disposed on a high pressure fuel pipe connecting common rail and a fuel injection valve.

The ECU calculates the actual amount Qpl of the pilot fuel injection from the magnitude P and pressure Pc in the high pressure fuel pipe based on the relationship between Qpl and P, Pc determined beforehand by experiment. The ECU further corrects the fuel injection period of the fuel injection valve in such a manner that the difference dQpli between the actual amount Qpl and a target amount Qplt of pilot fuel injection becomes within an allowable range.

Abstract: In an injection hole plate of a fuel injection device, injection holes are arranged about a circle. Fuel injected from the injection holes forms a flat sector-shaped spray. The intervals between adjacent injection holes are approximately equal to each other, while the diameters of the injection holes are equal to each other. An injection hole is positioned on an imaginary plane, which contains the central axis of the sector-shaped spray along the injection direction and is orthogonal or approximately orthogonal to the sector-shaped spray. The injection holes, away from the imaginary plane in this order, are symmetric with respect to the line of intersection of the injection hole plate and the imaginary plane. The farther each injection hole is away from the imaginary plane, the larger an angle of gradient of the injection hole with respect to the imaginary plane becomes.

Abstract: A device provided with a fuel injector and a reservoir for temporarily storing the fuel to be fed to the fuel injector. Fuel is injected at least two times in one engine cycle.

Due to the effects of the returned pulsation, the fuel injection amount in the later fuel injection fluctuates. The opening timing of the fuel injector and the fuel injection pressure are employed as parameters affecting the fuel injection amount in the later fuel injection, the amounts of fluctuation of the parameters due to the pulsation are estimated, and a control value relating to the operation of the fuel injector is controlled based on the estimated amounts of fluctuation of the parameters so that a target amount of fuel is injected from the fuel injector.

Abstract: In a power generation system of this invention, the outputs from power generation layers electrically connected in series are input to corresponding power conversion devices, and boosted outputs are connected in parallel and fed to a load. Alternatively, the output from one of power generation layers electrically connected in series is input to a first power conversion device, and the serial output and the boosted output from the first power conversion device are connected in parallel, input to a second power conversion device, boosted, and fed to the load.
