摘要： A method of controlling an engine is provided, which includes the steps of injecting main fuel by a fuel injector during an intake stroke or a compression stroke, providing a mixture gas containing fuel and air inside a cylinder, applying by an ignition device a high voltage between electrodes of a spark plug at a timing when the mixture gas is not ignited, detecting a parameter related to a current value of an electric-discharge channel generated between the electrodes, determining by a controller whether the detected parameter is within a range between a first threshold and a second threshold to determine a flowing state of a vortex inside the cylinder, operating the spark plug to carry out a supplemental ignition when the parameter is determined to be outside the range, and igniting the mixture gas by operation of the spark plug after the supplemental ignition.

摘要： Disclosed is an inventive method for controlling a corona ignition device of an internal combustion engine. A corona discharge, which ignites fuel in a combustion chamber of the engine, is generated by applying a voltage to the corona ignition device. An actual value that is characteristic of the nitrogen oxide concentration of the exhaust gas is compared with a setpoint value, and, if the actual value deviates from the setpoint value by more than a specified threshold value and the actual value is greater than the setpoint value, the voltage is reduced after the comparison.

摘要： A supercharged engine has a geometric compression ratio ser to 16 or more and is designed to perform a compression self-ignition combustion under an air-fuel ratio leaner than a stoichiometric air-fuel ratio at least in a low engine speed range. On a lower engine load side than a given engine load within an engine operating region at which the compression self-ignition combustion is performed, a fresh air amount is reduced and an effective compression ratio (ε′) is increased, as compared with a higher engine load side than the given engine load within the engine operating region, and, on the higher engine load side than the given engine load, a supercharging pressure based on a supercharger (25) is increased to increase the fresh air amount, and the effective compression ratio (ε′) is reduced, as compared with the lower engine load side than the given engine load. This makes it possible to perform the compression self-ignition combustion under a lean air-fuel ratio in a wider engine load range to effectively enhance engine thermal efficiency, while eliminating a need for an operation of forcedly raising/lowering a temperature of fresh air.
摘要翻译：增压发动机的几何压缩比为16以上，并且设计成在至少在低发动机转速范围内在比理论空燃比稀薄的空燃比下进行压缩自点燃燃烧。在比执行压缩自点火燃烧的发动机工作区域内的给定发动机负荷更低的发动机负荷侧，与较高的压缩自燃点相比，新鲜空气量减少并且有效压缩比（ε'）增加发动机负荷侧比发动机运转区域内的给定发动机负荷高，并且在比给定发动机负荷高的发动机负荷侧，增加基于增压器（25）的增压压力以增加新鲜空气量，并且有效与发动机负载侧相比，与给定的发动机负荷相比，压缩比（ε'）减小。这使得可以在更宽的发动机负载范围内在贫空燃比下进行压缩自点火燃烧，从而有效地提高发动机热效率，同时不需要强制升高/降低新鲜空气的温度。

摘要： The invention relates to a method for igniting a fuel-air mixture in an internal combustion engine. An electric transformer excites an oscillating circuit connected to a secondary winding of the transformer. A capacitor is formed by an ignition electrode together with the wall of a combustion chamber through which it extends. The excitation of the oscillating circuit is controlled by generating a corona discharge igniting the fuel-air mixture. Before each ignition time the voltage applied to a primary winding of the transformer is incrementally increased, and the intensity of the current flowing in the primary winding is measured repeatedly at the same primary voltage. The variation of the values of the related primary current is determined, and the incremental increase in the primary voltage is aborted at a value thereof at which the variation of the primary current intensity reaches or exceeds a predetermined limit.

The electrode is adjacent to but electrically insulated from an electrical conductor which receives current at frequencies between 100 kHz to 500 kHz. Thermal insulation is also provided between the electrode and adjacent structure of the head. The induction driven ignition system causes the electrodes to rapidly and accurately heat up to very high temperatures.

摘要： A multi-spark type ignition system for an internal combustion engine has a compact energy storage coil. The multi-spark type ignition system includes a energy storage coil, an energy storage capacitor, a first power transistor that switches on or off supply of electric energy from a battery and the electric energy from the energy storage coil to the energy storage capacitor, a second power transistor connected to the energy storage capacitor and to an ignition coil and an external resistor, connected between the energy storage coil and the first power transistor so as to bypass the energy storage capacitor. The second power transistor switches on or off the primary current. The external resistor limits current flowing through the first power transistor, thereby limiting temperature rise of the first power transistor.

摘要： An internal combustion engine includes a cylinder with a spark plug, an electric DC voltage supply, and an ignition circuit. The ignition circuit includes a switching device and a transformer having a primary winding coupled to the supply via the switching device, and a secondary winding coupled to the spark plug. After having generated an initial breakdown of a breakdown path through a gas mixture between electrodes of the spark plug, switching occurs repeatedly per combustion to produce pulses at the primary winding, with a repeat frequency which is at least sufficiently high that the breakdown path remains conductive between consecutive switches per combustion. The switching on and switching off provides heating of the breakdown path to ignite the gas mixture. The transformer has an air core around which the primary and secondary windings are arranged concentrically.
