Abstract

Es wird ein Niederdruck-Dieselmotor vorgeschlagen, bei dem die Verbrennungsdrücke diejenigen von Otto-Motoren nicht wesentlich überschreiten und die Verbrennungstempe­ raturen weit unter denen des Otto-Prozesses liegen, so daß bei Verwendung vorhandener Modelle dieser Bauart die Motorleistung gesteigert werden kann. A low pressure diesel engine is proposed at which the combustion pressures those of Otto engines not significantly exceed and the combustion temperature ratures are far below those of the Otto process, so that when using existing models of this type Engine power can be increased.

Grundlage des Vorschlages bildet die Kombination eines Dieselmotors mit einer Aufladeeinrichtung, vorzugsweise mit einem Rotationsschwinglader nach dem Europäischen Patent 0 012 329, wobei die Vorzüge dieser letzteren Einrichtung erhalten bleiben: Stark reduzierter Brennstoff­ verbrauch besonders im Teillastbereich, der idealen Zug­ krafthyperbel angenäherte Motorkennung, geringe Arbeits­ drehzahl, verringertes Geräusch, weniger toxische Abgase. The combination of one forms the basis of the proposal Diesel engine with a charger, preferably with a rotary swing loader according to the European Patent 0 012 329, the advantages of which are the latter Preserve furnishings: greatly reduced fuel consumption especially in the partial load range, the ideal train Force hyperbolic approximate engine identification, low work speed, reduced noise, less toxic exhaust fumes.

Dazu wird das Kompressionsverhältnis des Diesel-­ Motors bis etwa in den thermodynamisch noch günstigen Bereich von Otto-Motoren gesenkt, so daß Zündung des eingespritzten Brennstoffs nicht erfolgen würde, und die notwendige Zündtemperatur durch Aufheizung der Ladeluft um den entsprechenden Betrag gesichert. The compression ratio of the diesel Motors up to about the thermodynamically still favorable Area of Otto engines lowered so that ignition of the injected fuel would not take place, and the necessary ignition temperature by heating the charge air secured by the appropriate amount.

Diese Aufheizung erfolgt in den Motorarbeitsbereichen, in denen die Kompressionswärme des Laders nicht aus­ reicht, vorzugsweise durch eine Flamme und deren heiße Verbrennungsgase im Ladeluftstrom. Varianten, zB. Nut­ zung elektrischer Energie in irgendeiner Form, sind möglich. This heating takes place in the engine work areas, in which the compression heat of the loader does not run out ranges, preferably through a flame and its hot Combustion gases in the charge air flow. Variants, e.g. Groove electrical energy in any form are possible.

Sehr leichte 2-Takt- Niederdruck-Dieselmotoren sind so einfach zu bauen, mit geringem spezifischen Verbrauch, günstiger Kennung und niedrigem Gewicht, die sich beson­ ders für den Antrieb von Kleinflugzeugen eigenen. Very light 2-stroke low-pressure diesel engines are like this easy to build, with low specific consumption, favorable identifier and low weight, which is special own for the propulsion of small aircraft.
