Abstract

The piston of a reciprocating internal combustion engine has a thin sheet top (a) with a skirt below it containing grooves for the piston rings. It is attached to a piston rod (d) by a gudgeon pin (c). A deflector plate (b) is fitted inside the skirt between the gudgeon pin and the top plate (a) of the piston. The deflector plate prevents oil from the sump and connecting rod from splashing on the underside of the piston plate (a). This prevents cooling of the piston plate and also heating of the oil. It thus enables the piston to operate at a higher which increases the overall efficiency of the engine.

Description

Die heutige Zusatzanmeldung befasst sich mit der Verbesserung des Kolbens, indem unter dem Kolbenboden (Deckel) eine Glocke angeordnet wird. Der Stahlblech-Kolbenboden hat einen höheren Schmelzwert, daher den Vorteil, dass er entschieden höhere Temperaturen standhält. Die Unterplatte (b) hält das Spritz- oder Schleuderöl aus der Motorwanne vom Kolbendeckel fern und verhindert so die Kühlung des Kolbenbodens von der Ölwanne aus. Die Kolbenwand und Kolbenringe kühlen auch an der Zylinderwand. Die Unterplatte (b) unterbindet den größten Teil des in großem Maße unter den Kolbenboden spritzenden Öls aus der Motorwanne. Hierdurch kann der Kolbenboden je nach Anbringung der Glocke (b) eine gewünschte, entschieden höhere Temperatur erzielen. Dieses hat die Vorteile, dass durch die Platte (b) das Motoröl im Motor nicht so stark erhitzt wird, aber durch die höhere Temperatur des Kolbenbodens die Verdichtung und Verbrennung im Kompressionsraum entschieden verbessert wird. Dieses bedeutet bei heißerem Kolbenboden bessereToday's additional application deals with the improvement of the piston by placing a bell under the piston crown (cover). The sheet steel piston crown has a higher melting value, hence the advantage that it can withstand significantly higher temperatures. The lower plate (b) keeps the spray or centrifugal oil from the engine pan away from the piston cover and thus prevents the piston crown from cooling down from the oil pan. The piston wall and piston rings also cool on the cylinder wall. The lower plate (b) prevents most of the oil from the engine pan, which splashes a great deal under the piston crown. As a result, the piston crown can reach a desired, decidedly higher temperature, depending on how the bell (b) is attached. This has the advantage that the engine oil in the engine is not heated as much due to the plate (b), but the higher temperature of the piston crown improves the compression and combustion in the compression chamber. This means better if the piston crown is hotter
