    摘要: The object is to provide an injector with a built-in ignition device that can achieve downsize of device as a whole without changing significantly the structure of a fuel injection device. The injector with the built-in ignition device comprises an ignition device 3 and a fuel injection device 2. In the ignition device 3, an electromagnetic wave oscillated from an electromagnetic wave oscillator MW is boosted by a booster that is constituted by a resonance structure, a potential difference between a ground electrode 51 and a discharge electrode 31 is increased, and a discharge is caused. In the fuel injection device 2, a valve body part of a nozzle needle 24 is moved toward or away from a valve seat (orifis) 23a, and thereby, the fuel injection control is performed. Then, the resonance structure is formed by a dielectric member 30 that is connected to the electromagnetic wave oscillator and formed on the surface of a fuel injection pipe 21, and an inner wall surface 50a of a mounting port 50 for an injector of a cylinder head 5. A discharge electrode 31 is a projection that is formed on the surface of the fuel injection pipe 21, and a discharge is caused by making a position of the wall surface of the mounting port 5 that is closest to the discharge electrode 31 as a ground electrode 51.

    摘要: An igniter semiconductor device and an igniter system can prevent the influence of a voltage drop of an ON signal voltage input to an input terminal and the influence of a surge voltage, allow a switching element to operate reliably, and prevent an ignition failure. The igniter semiconductor device includes an external terminal including at least an input terminal, an output terminal electrically connected to an ignition coil, a ground terminal, and a power supply terminal electrically connected to a regulated power supply wire outside the igniter semiconductor device. The ignited semiconductor device further includes a switching element for controlling current flowing in the ignition coil, and a driving circuit that receives power through the power supply terminal and drives the switching element based on a signal input from the input terminal.

    摘要: An ECU outputs an ignition signal Si to an ignition apparatus through an ignition communication line. The ignition apparatus performs the closing operation of an ignition switching element, in a period during which the ignition signal Si is input. The ECU outputs a discharge waveform control signal Sc to a waveform control communication line, at a timing that is delayed by a predetermined delay time relative to an output timing of the ignition signal Si. In an input period of the discharge waveform control signal Sc after the stop of the input of the ignition signal Si, the ignition apparatus controls the electric current to flow through a primary coil, to a discharge current command value that is decided depending on the above delay time, by the opening-closing operation of a control switching element.

    摘要: The present invention relates to a method for monitoring the combustion chamber of a cyclically operating combustion engine in which an air-fuel-mixture is ignited by means of a corona discharge generated by an electrical oscillating circuit in which an ignition electrode, which is electrically isolated from the combustion chamber walls, and the combustion chamber walls form a capacitor, wherein by evaluating an electrical parameter of the oscillating circuit information about the combustion chamber is gained. The voltage exciting the oscillating circuit is reduced after the beginning of the combustion and the oscillating circuit is then excited with a reduced voltage.
