    摘要: A fuel-injection system for direct injection of fuel into a combustion chamber through a combustion-chamber top arranged opposite a piston has a fuel injector which includes an actuable valve-closure member. The valve-closure member cooperates with a valve-seat surface to form a sealing seat. A multitude of spray-discharge orifices generates a spray cloud, each spray-discharge orifice generating a fuel jet, and the multitude of fuel jets generating the spray cloud in the combustion chamber. A first opening angle of the spray cloud in a first plane is greater than a second opening angle in a second plane extending perpendicular to the first plane.

    摘要: A high-voltage switch is suggested, particularly for ignition systems of internal combustion engines, which is characterized by a voltage-controlled electronic high-voltage switching unit which passes suddenly from the blocking state into the conducting state at a preselectable and predetermined voltage. The switching unit uses a state-changing or breakdown diode cascade (8) which switches through the voltage at the secondary winding (5) of an ignition coil (7) only after reaching the ignition voltage at the spark plug (1) of an internal combustion engine.

    摘要: A spark plug with creepage spark gap for internal combustion engines includes a plug housing having an annular side electrode, an insulator, surrounded by the plug housing over a longitudinal section, and a central electrode. The layer lies in a through-bore of the insulator and is exposed on the combustion chamber end side. The creepage spark gap is formed between the central electrode and the side electrode along a slideway on the surface of the insulator. To achieve a small plug capacitance with high-dielectric slideway, the insulator has, at least at the end section on the combustion chamber side, at least two coaxial material layers, having very different dielectric constants. These coaxial layers lie or partially lie against each other in a radial direction of the spark plug.

    摘要: A spark plug for internal combustion engines comprises a center electrode enclosed in an insulating body enclosed in a metal housing, and a ground electrode. The insulating body has an end portion which faces the combustion chamber. An electrical field develops, resulting in a surface spark gap between two electrodes on the surface of the insulating body at the end portion thereof. The insulating body is transversely divided into the upper portion and the lower portion, of which the lower portion facing the combustion chamber is made of a material having dielectric constant 5-50 times higher than that of the upper portion.

To attain extensive homogeneity of the mixture formation in direct fuel injection that assures reliable, thorough combustion of the mixture, the combustion chamber is preceded at its upper end by a chamber, which opens toward the combustion chamber and has an inside cross section that is substantially smaller than the combustion chamber and increases steadily toward the combustion chamber. The injection and ignition take place in the chamber.
