Embodiment Construction

[0042] In the figures, the same or the same type of parts are denoted by the same reference numerals. The drawings show examples only and are not to be construed as limiting.

[0043] figure 1 A plan view of a connecting rod 1 according to the invention for an internal combustion engine with a variable compression ratio is shown, the connecting rod being shown as an example. Link 1 is shown in a low compression position. exist figure 2 The basis for having drawn section plane A-A is shown in figure 1 side view of connecting rod 1, and image 3 show the basis figure 1 and figure 2 The longitudinal section in the section plane A-A of the connecting rod 1.

[0044] The connecting rod 1 has an eccentric adjustment device 5 for adjusting the effective connecting rod length 50 . However, the application of the invention is not limited to the specific embodiment of the connecting rod 1 described.

[0045] The connecting rod 1 comprises a connecting rod body 2 and a connect...

Abstract

The invention relates to a connecting rod for an internal combustion engine having a variable compression ratio. The connecting rod includes a connecting rod body and a connecting rod cap connected to the connecting rod body, the connecting rod body and the connecting rod cap forms a crankpin bearing eye. A separating gap between the connecting rod body and the connecting rod cover is inclined relative to the transverse axis of the crank pin bearing hole, and the connecting rod body and the connecting rod cover are provided with a first separating surface and a second separating surface, and a third separating surface and a fourth separating surface which are radially opposite to each other on the crank pin bearing hole. The separating surfaces form the separating gap when the connecting rod body and the connecting rod cover are assembled. The hydraulic pipeline penetrates through the separation gap between the connecting rod body and the connecting rod cover on the crank pin bearing hole. The separating surfaces are connected without leakage on the side of the crank pin bearing eye that guides the hydraulic fluid. The invention also relates to an internal combustion engine having a connecting rod.

Description

technical field [0001] The invention relates to a connecting rod for an internal combustion engine with a variable compression ratio, said connecting rod having an adjusting device for adjusting the effective connecting rod length, and to a connecting rod having such a connecting rod with a settable compression ratio. Rod internal combustion engine. Background technique [0002] In internal combustion engines, a high compression ratio has a positive effect on the efficiency of the internal combustion engine. Compression ratio is generally understood as the ratio of the entire cylinder volume before compression to the remaining cylinder volume after compression. However, in internal combustion engines with external ignition having a fixed compression ratio, in particular gasoline engines, the compression ratio can only be selected so high that a so-called “knock” of the internal combustion engine is avoided during full load operation. However, for the more frequently occurr...
