| 摘要 |
The invention relates to an internal combustion engine (1) with an adjustable variable compression ratio and a connecting rod (2) having an adjusting mechanism (3) for adjusting the adjustable variable compression ratio, comprising a first hydraulic line (34.1), a second hydraulic line (34.2), a hydraulic outlet, and a switch (41) for switching the adjusting mechanism (3). The switch (41) is arranged on the connecting rod (2) and has a first inlet (42), a second inlet (43), and an outlet (44). In a first position of the switch (41), the first hydraulic line (34.1) is fluidically connected to the hydraulic outlet via the first inlet and the outlet, and a fluid connection between the second hydraulic line (34.2) and the hydraulic outlet is interrupted. In a second position of the switch, the second hydraulic line (34.2) is fluidically connected to the hydraulic outlet via the second inlet (43) and the outlet (44), and a fluid connection between the first hydraulic line (34.1) and the hydraulic outlet is interrupted. The switch (41) has a sealing surface (47), the first inlet (42) has a first passage (45), and the second inlet (43) has a second passage (46). The sealing surface (47) delimits the first inlet (42) from the second inlet (43), and the switch (41) and the connecting rod (2) can be moved relative to each other. The first passage (45) and the second passage (46) are moved together with the switch (41) when switching from the first position to the second position and vice versa. |
