Description

Erreichte VorteileBenefits achieved

Die Hochdruck-Echozündung ermöglicht Benzinmotore mit Dieselkraftstoff zu betreiben ohne lästigen Ruß zu erzeugen und ohne störende Nebengeräusche, wie sie beim Verbrennen von Diesel üblich sind ("Nageln").High-pressure echo ignition enables gasoline engines to run on diesel fuel without producing annoying soot and without the annoying background noises that are common when diesel is burned ("knocking").

Das geringe Gewicht der Hochdruck-Echozündung.The low weight of the high pressure echo ignition.

Es können höhere Drehzahlen erreicht werden, wodurch der Geräuschpegel des Motors verringert wird.Higher speeds can be achieved, reducing the noise level of the engine.

Hochdruck-Echozündung für Zwei- und Viertakt-VerbrennungsmotoreHigh-pressure echo ignition for two- and four-stroke combustion engines

Die Hochdruck-Echozündung besteht aus einer beweglichen Brennkammer ( Fig.1) mit einem Kegelventil (Fig. 4), unter dem zwei Einlaßschlitze (Fig. 5) angeordnet sind, einem Druckspeicher (Fig. 2) in dem eine Hubbegrenzung ist und wird durch ein normales Zündkerzen-Gewinde (Fig. 2.1) im Motor befestigt.The high-pressure echo ignition consists of a movable combustion chamber (Fig. 1) with a cone valve (Fig. 4), under which two inlet slots (Fig. 5) are arranged , a pressure accumulator (Fig. 2) in which there is a stroke limiter and is attached to the engine by a normal spark plug thread (Fig. 2.1).

Die Brennkammer (Fig. 1) ist nach unten offen und wird kurz vor dem oberen Totpunkt durch den Motorkolben geschlossen und angehoben. In der Brennkammer ist jetzt hochverdichtetes Kraftstoff-Luftgemisch eingeschlossen. Beim Anheben der Brennkammer öffnet sich das Kegelventil (Fig. 4). Aus dem Speicher (Fig. 2) strömt ein hoher Druck in die Brennkammer, die zu diesem Zeitpunkt vom Motorkolben verschlossen ist und löst die Zündung aus. Der absteigende Motorkolben öffnet die Brennkammer, das Kraftstoff-Luftgemisch im Motor wird gezündet. Der überhöhte Druck im Speicher wird bei jeder Zündung wie ein Echo immer wieder nachgefüllt, da das Kegelventil (Fig. 4) sich erst dann schließt, wenn der Druck im Motor geringer ist.The combustion chamber (Fig. 1) is open at the bottom and is closed and raised by the engine piston shortly before top dead center. A highly compressed fuel-air mixture is now enclosed in the combustion chamber. When the combustion chamber is raised, the cone valve (Fig. 4) opens. High pressure flows from the reservoir (Fig. 2) into the combustion chamber, which is closed by the engine piston at this time, and triggers the ignition. The descending engine piston opens the combustion chamber and the fuel-air mixture in the engine is ignited. The excessive pressure in the reservoir is repeatedly refilled like an echo with each ignition, since the cone valve (Fig. 4) only closes when the pressure in the engine is lower.

Mit dieser Hochdruck-Echozündung können normale Benzinmotore mit einer Verdichtung von 1 : 10 mit Dieselkraftstoff betrieben werden, vor allem 2-Takt-Motoren. Bei 4-Takt-Motoren ist dies nur mit einem zusätzlichem Magnetventil möglich.With this high-pressure echo ignition, normal petrol engines with a compression ratio of 1:10 can be operated with diesel fuel, especially 2-stroke engines. With 4-stroke engines, this is only possible with an additional solenoid valve.
