Embodiment 1
[0041] see figure 1 , this embodiment discloses an engine cylinder group, including a cylinder block 1 and a hydraulic cylinder block 2, the hydraulic cylinder block 2 is located at the lower end of the cylinder block 1, and the head end of the hydraulic cylinder block 2 is connected with the lower end of the cylinder block 1, so that the hydraulic pressure The inner cavity of the cylinder block 2 communicates with the inner cavity of the cylinder block 1, and the hydraulic piston 4 is arranged in the hydraulic cylinder block 2, and the hydraulic piston 4 is in sliding and sealing cooperation with the inner wall of the hydraulic cylinder block 2. An isolation piston 3 is provided, and the isolation piston 3 is in sliding and sealing cooperation with the inner wall of the cylinder body 1. A certain amount of liquid 17 is filled between the isolation piston 3 and the hydraulic piston 4 (the amount of liquid to be filled is determined according to the actual situation, generally n...
Embodiment 2
[0057] see Figure 4, this embodiment discloses an engine cylinder group, including a cylinder block 1 and a hydraulic cylinder block 2, an extension part is added to the cylinder block 1, the hydraulic cylinder block 2 is arranged laterally at the lower end side of the cylinder block 1, and the head of the hydraulic cylinder block 2 The end communicates with the side wall of the cylinder block 1, the hydraulic cylinder block 2 is provided with a hydraulic piston 4, and the hydraulic piston 4 is in sliding and sealing cooperation with the inner wall of the hydraulic cylinder block 2, and the cylinder block 1 is provided with an isolation piston 3 , the isolation piston 3 is in sliding and sealing cooperation with the inner wall of the cylinder block 1, the bottom of the cylinder block 1 is sealed, and a certain amount of liquid 17 is filled between the isolation piston 3 and the hydraulic piston 4, (the liquid filled in is determined according to the actual situation Generally...
Embodiment 3
[0068] see figure 1 , the present embodiment discloses an engine with improved compression ratio, comprising at least one engine cylinder group as described in Embodiment 1, the hydraulic cylinder block 2 tail ends of each engine cylinder group are open, and the hydraulic pistons 4 of each engine cylinder group Connect with the crankshaft 7 in the crankshaft 7 case by connecting rod 9. Of course, it is also possible to connect the hydraulic piston 4 to the piston rod 8 and connect the piston rod 8 to the connecting rod 9. The hinged connection between the piston rod 8 and the connecting rod 9 can be the same as the original piston and the connecting rod 9. Certainly, It can be adjusted according to actual needs.
