DOI: Direct use of biomass powder in internal combustion engines L. Stover, B. In a particularly preferred embodiment of the invention there is mounted a small-sized permanent magnet machine based on the performance as a driving engine or load, which results in further advantages with respect to the driving engine or load below the available space.
In an additional preferred embodiment of the invention it is provided that two or more driving engine or load units in series one behind the other and parallel to each other are mounted hanging and rotationally connected in this case via a coupling gear with a aligned with the output shaft of the internal combustion engine, the input or output shaft.
This solution is particularly very advantageous for larger test performance, since two or more together, the power required deliverables machines still have only the interference contour from the axis of downwardly into the the exhaust system to be kept free space projecting a similar machine.
Also can be, for example, with the communication or primary gear often the required power or speed ranges more easily realized. The support assembly may spread in an additional preferred embodiment of the invention a foundation plate of the foundation bridge-like and be supported on both sides on this and fixed, resulting in a very stable and advantageous in terms of vibration occurring in the test structure.
According to another preferred embodiment of the invention, the foundation may in quasi-three-dimensional configuration for example, as a stable test container but also even the driving engine or load at least partially overlap in height, in which case the support assembly from the top or from the side of this three-dimensional foundation mounted the driving engine or load carrying suspended, for example by means of a hanging V-shaped arrangement. The driving engine or load can be suspended in an additional preferred embodiment of the invention, with the interposition of vibration on the support assembly, allowing an improved vibration decoupling, can be influenced, moreover, via appropriate other measures of the frame structure.
The invention is illustrated in more with reference to the schematically shown in the drawings embodiments. The test bench shown in all cases, as a foundation 1, a base plate 12 on which the internal combustion engine 2 to be tested only in Fig. The driving engine or load 4 embodied for example as a permanent magnet machine is mounted at a vertical distance 5 to the base plate 12 hanging on a arranged on this support assembly 6 substantially coincides with the output shaft 7 of aligned to be tested engine 2 axis 8, so that below the interference contour 9 of the drive- or load generator 4 remains room for the mounted on the internal combustion engine 2 original exhaust system 10 sufficiently.
While only one driving engine or load 4 is provided in the embodiments according to FIGS. In the embodiment of FIG.
In contrast, in the embodiment of Fig. Apart from these two variants with a separately in the test area for the most part isolated from vibrations established foundation plate 12, the foundation 1 but could encompass not illustrated herein, also in quasi-three-dimensional configuration of the internal combustion engine to be tested and the driving engine or load container or cage-like, in which case the support assembly attached to the side or from above, at this foundation and the internal combustion engine to be tested could also be fastened directly by means of a conventional test range. Specifically, from FIGS.

Country of ref document : US. In order to make it possible to also mount an original exhaust system 10 substantially leading away from the internal combustion engine 2 below the output axle 7 parallel to the extension thereof in a test rig for internal combustion engines 2 , the driving engine or load generator 4 is mounted in a suspended manner at a certain vertical distance from the pedestal 1 on a support arrangement 6 mounted thereon, with the input axle 8 being substantially aligned with the output axle 7 of the internal combustion engine 2 that is to be tested, whereby the space from below the interference contour 9 of the driving engine or load generator 4 to the pedestal remains free for the passage of the exhaust system Test bed for internal combustion engines The invention relates to a test stand for internal combustion engines, the internal combustion engine to be tested on the one hand and the output side at least one rotationally connected drive or loading machine is arranged on the other hand with a foundation on the opposite.
A test bed according to claim 1, characterized in that as the driving engine or load 4 is based on the performance of small-sized permanent magnet machine is mounted. A test bed according to claim 1 or 2, characterized in that two or more drive or loading machine 4 in series one behind the other or are mounted parallel to each other and suspended rotationally connected.
A test bed according to any one of claims 1 to 3, characterized in that the support assembly 6 a foundation plate of the foundation 1 is bridge-like manner and engages on both sides supported on the latter and fixed. A test bed according to any one of claims 1 to 3, characterized in that the support assembly 6 on one side only on a foundation plate of the foundation is supported 1 and secured. A test bed according to any one of claims 1 to 3, characterized in that the foundation 1 itself, the driving engine or load 4 at least partially overlaps in height and that the supporting arrangement 6 from above or from the side hanging forth the driving engine or load 4 bears.
A test bed according to one or more of claims 1 to 6, characterized in that the driving engine or load 4 with the interposition of vibration dampers 11 on the support assembly 6 is suspended. USB2 en. EPB2 en.
