Description

Vorrichtung zum Messen der Größe des Kompressionsraumes von Verbrennungskraftmaschinen. Die bisher bekannte Messung der Größe des Kompres:sionsraumesi bei Nerbrennungskraftmaschinen, die durch Einfüllen von Schmieröl bewerkstelligt wird, ist sehr ungenau; zeitraubend und mit großen Olv erlusten verbunden.Device for measuring the size of the compression space of internal combustion engines. The previously known measurement of the size of the compression space in internal combustion engines, which is accomplished by adding lubricating oil is very imprecise; time consuming and associated with great olv losses.

Es. sind anderseits bereits Raummesser bekannt, die aus einem unter einem bestimmten Druck stehenden Meßgefäß bestehen, das mit dem zu messenden Raume in Verbindung gebracht wird. Aus dem hierbei sich ergebenden Druckunterschied im 1bIeß:gefäß kann dann der zu messende Rauminhalt nach dem Mariotteschen Gesetz leicht berechnet werden. eines derartigen Meßgefäßes zur Bestimmung Die Erfindung betrifft nun die Anwendung des Kompressionsraumes von Motoren.It. on the other hand, space knives are already known, which consist of a a certain pressure standing measuring vessel exist with the room to be measured is associated. From the resulting pressure difference in 1bIß: the volume to be measured can then easily be measured according to Mariott's law be calculated. of such a measuring vessel for determination. The invention relates to now the application of the compression chamber of engines.

In der Zeichnung ist die Meßv orrichtung dargestellt. Sie besteht aus dem Meßgefäß a mit Manometer b, Luftpumpenanschluß c, Zwischenhahn d und Anschluß e.In the drawing, the measuring device is shown. she consists from measuring vessel a with manometer b, air pump connection c, intermediate tap d and connection e.

Zur Messung der Größe des Kompressionsraumes, von dem die Leistung der Verbrennungskraftmaschinen abhängt, wird mittels des Anschlusses e die Meßvorrichtung mit dem Motorzylinder f irr Verbindung gebracht, der Zwischenhahn d geschlossen und das Meßäefäß a durch den Luftpumpenanschluß c mit einer Fahrradluftpumpe unter bestimmten Druck gesetzt. Hierauf wird der Zwischenhahn geöffnet und nach dem Druckausgleich der verminderte Druck abgelesen. Aus den Drucken vor und nach dem öffnen des Zwischenhahnes, dem bekannten Meßgefäßvolumen und dem Volumen der Verbindungsleitung läßt sich nach dem Mariotteschen Gesetz in bekannter Weise das Volumen des Kompressionsraumes leicht errechnen.To measure the size of the compression space from which the performance depends on the internal combustion engine, the measuring device connected to the engine cylinder, the intermediate valve d closed and the measuring vessel a through the air pump connection c with a bicycle air pump set certain pressure. The intermediate tap is then opened and after pressure equalization read the reduced pressure. From the prints before and after opening the intermediate tap, the known measuring vessel volume and the volume of the connecting line can be adjusted the volume of the compression space slightly according to Mariott's law in a well-known way calculate.

Ist das Volumen des Meßgefäßes Va, das Volumen der Verbindungsleitung vom Zwischenhahn bis zum Kompressionsraum V r, der Druck im Meßgefäß bei geschlossenem Hahn pa, oder Enddruck im Gesamtraum nach öffnen des Zwischenhahnes pe und das Volumen des Kompressionsraumes Vk, so ist Ist zum Beispiel Va - Soo cm.', Vr - 5 cmg, pa - 0,5 kg/om2, pe - 0,2 kg/cm2, so ergibt sich If the volume of the measuring vessel Va, the volume of the connecting line from the intermediate tap to the compression chamber V r, the pressure in the measuring vessel with the tap closed pa, or the final pressure in the entire chamber after opening the intermediate tap pe and the volume of the compression chamber Vk, then is For example, if Va - Soo cm. ', Vr - 5 cmg, pa - 0.5 kg / om2, pe - 0.2 kg / cm2, the result is
