Publication number: 20140116382Abstract: The invention relates to a method for generating an ion current which occurs as a direct current between a central electrode and one or more side electrodes of a spark plug of a spark ignition engine which is supplied repeatedly with an ignition voltage from an ignition voltage source, wherein the spark ignition engine is assigned an engine control unit, which, in an engine cycle, determines for each spark plug a target ignition point and/or an activation point for the ignition voltage source before the target ignition point, and a second voltage source is provided, which delivers a second voltage for the generation of the ion current, wherein the second voltage source lying in the engine cycle for a first time interval ?t1, which is shorter than the duration of the engine cycle, is connected to the electrodes of the spark plug, and wherein the ion current flowing as a result of the application of the second voltage to the electrodes of the spark plug takes a path which avoids the ignition voltage source.Type: ApplicationFiled: October 25, 2013Publication date: May 1, 2014Inventors: Arun Sasikumar Sujatha, Ganghua Ruan, Stefan Heinzelmann, Dirk Wüstenhagen, Ulrich Schönauer

Publication number: 20140116383Abstract: A vibration waveform of a knock-specific frequency component of an internal combustion engine is calculated over a plurality of ignition cycles of the internal combustion engine according to an output of a knock sensor and an output of a crank angle sensor. An actual ignition timing is calculated by detecting a position corresponding to a crank angle at which a standard deviation of the vibration waveform exceeds a predetermined first determination level as a vibration position by combustion of the internal combustion engine.Type: ApplicationFiled: March 19, 2013Publication date: May 1, 2014Inventor: Yuhei MATSUSHIMA

Publication number: 20140116384Abstract: An air/fuel mixer system of a combustion chamber of a gas turbine includes at least one compressed air intake swirler, the swirler having a central axis of symmetry, and a fuel injector including an injection head having an axis of symmetry. Each injector is mounted in the corresponding swirler with aid of a guide mechanism, so that the axis of symmetry of the injection head is off-center with respect to the central axis of symmetry of the swirler. The system can reduce, or even eliminate, combustion instabilities, by injecting the fuel along a particular axis which is off-center relative to the axis of the air/fuel mixer system, inducing a flow of fuel which is no longer perfectly axially symmetrical.Type: ApplicationFiled: June 19, 2012Publication date: May 1, 2014Applicant: TURBOMECAInventors: Nicolas Savary, Claude Berat, Hubert Hippolyte Vignau, Christophe Nicolas Henri Viguier

Publication number: 20140116389Abstract: A single-cylinder, dual head internal combustion engine wherein in a single, mechanically unconstrained piston moves reciprocally within the cylinder between the two heads. Magnets or nonmagnetized ferromagnetic structures in the piston interact with magnets in a sleeve riding on the outside surface of the cylinder to cause synchronous movement of the sleeve. A yoke coupled to the sleeve may be coupled to a conventional crankshaft to convert the reciprocal movement of the sleeve into rotary motion. Multiple single-cylinder, dual head units may be ganged to form multi-cylinder engine configurations. In one embodiment, the magnets in the sleeve are electromagnets whereby de-energizing the electromagnets decouples the sleeve from the piston, thereby eliminating the need for a mechanical clutch in a power train driven by the engine.Type: ApplicationFiled: January 8, 2014Publication date: May 1, 2014Inventor: Boris Khurgin
