Embodiment Construction
[0046] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0047] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0048]This embodiment relates to a variable compression ratio mechanism with variable stroke. The variable compression ratio mechanism with variable stroke is controlled by the engine control unit so as to be able to adjust the engine piston stroke and compression ratio, and as figure 1 As shown in , its overall structure includes a piston 1, a crankshaft 4, an eccentric shaft 7, a control shaft 9, and a connecting rod 2, an adjusting connecting rod 3, a driving connecting rod 5 and a swing connecting rod arranged between the above-mentioned components. The multi-link structure formed by the rod 6 and the follower link 8.
[0049] Specifically, the piston 1 is slidably arranged in the c...
