    摘要: A method includes forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into a cylinder, compressing the combustible mixture with a piston in a compression stroke, introducing a second fuel into a prechamber at an introduction-time before start of combustion thus creating a prechamber charge, in which the second fuel being of the same or different chemical composition and/or concentration with respect to the first fuel, and spark igniting the prechamber charge. Emission of the cylinder and/or mechanical stress of the cylinder caused by the combustion are monitored. If emissions and/or mechanical stress are above respective predetermined thresholds, individually for the at least one cylinder, the chemical composition and/or the amount of second fuel introduced into the prechamber, and/or temperature of the cylinder charge and/or spark timing , are changed.

    摘要: The invention provides a system and method for controlling corona discharge and arc formations during a single corona event, i.e. intra-event control. A driver circuit provides energy to the corona igniter and detects any arc formation. In response to each arc formation, the energy provided to the corona igniter is shut off for short time. The driver circuit also obtains information about the arc formations, such as timing of the first arc formation and number of occurrences. A control unit then adjusts the energy provided to the corona igniter after the shut off time and during the same corona event based on the information about the arc formations. For example, the voltage level could be reduced or the shut-off time could be increased to limit arc formations and increase the size of the corona discharge during the same corona event.

    摘要: Method and apparatus for operating a two-cycle or four-cycle externally excited combustion engine with external ignition means where at least the fuel required for the ignition is introduced without admixture of main air into an evaporating chamber open toward the combustion chamber where it is precipitated against a non-water cooled wall that is hot during operation and which is elongated and encompasses the vaporizing chamber, is vaporized and is pushed to the ignition point in the vaporizing chamber together with some air until ignition takes place and where immediately after the ignition burning mixture is blown out of the vaporizing chamber into the combustion chamber, where the introduction of the fuel into the vaporizing chamber begins preferably at the end or shortly after the power stroke, after which during the compression stroke compressed air or compressed air-fuel mixture is pushed out of the combustion chamber into the vaporizing chamber, is mixed therein with vaporized fuel and the mixture is pushed to the ignition point provided in the vaporizing chamber, while simultaneously the burned out fuel gas in the vaporizing chamber is moved into a closed end of the vaporizing chamber and is compressed there, whereupon after the ignition burning mixture is blown away from the ignition point in the form of a bunched, very rapid stream of flames through the vaporizing chamber and, subsequently, the last parts of the burning mixture are displaced in the vaporizing chamber toward the combustion chamber by the burned out fuel gas.
