Abstract

The engine comprises a special double piston. During upwards motion it sucks in fresh air via inlet valves (4) into a suction chamber (8). The latter increased size safeguards displacement of all combustion gases from the combustion chamber and increases the charge pressure. Then fresh air is forced into the combustion chamber (7) via a link duct (16) and inlet pressure valve (5) and thus the combustion gases are displaced via the outlet (3). Fuel is fed by the injection valve (12).

Description

In dem neuen Zweitakter wird nicht wie sonst Öl mitverbrannt. Dieses wird mit dem Spezialdoppelkolben erreicht. Er saugt bei der Aufwärtsbewegung die Frischluft durch das (4) Einlaßventile in die (8) Ansaugkammer. Hierbei ist das Volumen der (8) Ansaugkammer extra etwas größer gehalten, damitIn the new two-stroke engine, oil is not burned as usual. This is achieved with the special double piston. During the upward movement, it sucks the fresh air through the ( 4 ) inlet valve into the ( 8 ) suction chamber. Here, the volume of the ( 8 ) suction chamber is kept slightly larger, so

  • 1. sämtliche Verbrennungsgase aus der Brennkammer gedrückt werden,1. all combustion gases from the Combustion chamber are pressed
  • 2. der Ladedruck erhöht wird. Leistungssteigerung.2. the boost pressure is increased. Performance increase.

Die Frischluft wird dann bei der Abwärtsbewegung durch den (16) Verbindungskanal durch das (5) Einlaßdruckventil in die (7) Brennkammer gedrückt und dadurch die Verbrennungsgase durch den (3) Auslaß verdrängt. Bei erneuter Aufwärtsbewegung wird dann der Kraftstoff durch das (12) Einspritzmagnetventil befördert. Wobei es hier als Kraftstoffe sowohl Benzine, Alkohole, Methanole und durch Veränderungen "Austausch von Zündkerzen durch Glühkerzen, Verdichtungsverhältnis" auch Diesel und pflanzliche Öle sein können.The fresh air is then pressed during the downward movement through the ( 16 ) connecting channel through the ( 5 ) inlet pressure valve into the ( 7 ) combustion chamber and the combustion gases are thereby displaced through the ( 3 ) outlet. When the upward movement is repeated, the fuel is then conveyed through the ( 12 ) injection solenoid valve. However, as fuels it can be petrol, alcohols, methanol and, due to changes "replacement of spark plugs with glow plugs, compression ratio", also diesel and vegetable oils.

Es wird also zu keinem Zeitpunkt Schmieröl hinzugeführt.Lubricating oil is therefore never added.

Die Schmierung erfolgt zwischen den oberen und unteren Teilen des (1) Spezialdoppelkolbens in der (2) Schmiermittelkammer. Dabei wird bei der Kolbenbewegung überschüssiges Öl in den (6) Ölausgleichbehälter gedrückt. Der Sinn der (11) gezogenen Rillen besteht darin, Öl aufzunehmen, um so den oberen und den unteren Teil des (1) Spezialdoppelkolbens zu schmieren. Durch die (11) gezogenen Rillen wird auch die Reibung in diesem Abschnitt verringert, also auch der Verschleiß.Lubrication takes place between the upper and lower parts of the ( 1 ) special double piston in the ( 2 ) lubricant chamber. Excess oil is pressed into the ( 6 ) oil expansion tank when the piston moves. The purpose of the ( 11 ) drawn grooves is to absorb oil so as to lubricate the upper and lower part of the ( 1 ) special double piston. The ( 11 ) grooves also reduce the friction in this section, including wear.

Man könnte auch (2) Schmiermittelkammer mit dem Kurbelwellengehäuse verbinden, wodurch aber auch eine Ölpumpe erforderlich wird. Dann könnte man aber nicht zwei verschiedene Schmieröle, die auf ihre Anforderung verschieden abgestimmt sind, verwenden.One could also connect ( 2 ) the lubricant chamber to the crankcase, but this also requires an oil pump. Then you could not use two different lubricating oils, which are tailored to your requirements.

Auch das Schmierungsproblem könnte auf eine andere Art gelöst werden. Durch zwei getrennte Einzelkolben, wo der eine Kolben die Ansaugung und der andere die Verdichtung verrichten.The lubrication problem could also be solved in a different way. By two separate single pistons, where one piston is the intake and the other do the compaction.

Dabei ist aber die kompakte Bauart nicht mehr gegeben.However, the compact design is no longer available.

Die (13) Spiralfeder hat die Aufgabe, bei Zündung die auftretenden Beschleunigungsspitzen aufzunehmen und sie gleichmäßiger auf den unteren Teil des (1) Spezialdoppelkolbens, Pleuelstange weiterzugeben. Dadurch werden die Lager (Lagerschalen) einem geringeren Verschleiß ausgesetzt.The task of the ( 13 ) coil spring is to absorb the acceleration peaks that occur when the ignition is applied and to pass them on to the lower part of the ( 1 ) special double piston, connecting rod. As a result, the bearings (bearing shells) are exposed to less wear.

Das heißt also, daß sich der (1) Spezialdoppelkolben einige Millimeter (8-15) zusammendrücken läßt. Das Auseinandergehen wird dann durch die (15) Gummipufferung aufgefangen.This means that the ( 1 ) special double piston can be compressed a few millimeters (8-15). The divergence is then absorbed by the ( 15 ) rubber buffer.

Claims (1)

Der Patentanspruch bezieht sich auf die Arbeitsweise eines Verbrennungsmotors (Zweitakters) ohne Ölmitverbrennung, das heißt, es wird zu keinem Zeitpunkt Öl bewußt mitverbrannt. Daher können auch andere Kraftstoffe (Alkohole, Methanole und durch geringe Umbaumaßnahmen Diesel, pflanzliche Öle verwendet werden, mit verschleißmindernden Bestandteilen (gezogenen Rillen, gepufferten Kolben).The claim relates to the operation of an internal combustion engine (Two-stroke) without oil co-combustion, that is, it never becomes oil consciously burned. Therefore, other fuels (alcohols, methanols and by minor remodeling diesel, vegetable oils used with wear-reducing components (drawn grooves, buffered pistons).
