Embodiment 1

[0015] Embodiment 1: as figure 1 As shown, a piston internal combustion engine includes a cylinder block 1, a cylinder head 2 arranged at the end of the cylinder block 1, a piston 3 and a connecting rod 4 connected to the piston 3, and the stroke distance of the piston 3 relative to the cylinder head 2 is set by the piston 3 Adjust with the variable stroke device between connecting rod 4. The stroke changing device includes an elastic body 5 arranged between the piston 3 and the connecting rod 4, the piston 3 and the connecting rod 4 form an axially movable connection through the cooperation of the connecting pin 6 and the elongated pin groove, and the elastic body 5 is arranged between the connecting pin 6 and the elongated pin groove and the end of the piston 3 facing the cylinder head 2. Generally speaking, the elongated pin groove can be arranged on the piston 3 or on the connecting rod 4 , as long as the thrust direction of the elastic body 5 is to push the piston 3 to t...

Embodiment 2

[0016] Embodiment 2: as figure 2 As shown, the piston internal combustion engine of this embodiment is basically the same as that of Embodiment 1, the difference is that the stroke distance of the piston 3 relative to the cylinder head 2 is adjusted by the variable stroke device arranged between the piston 3 and the connecting rod 4, and the variable stroke The device includes a cylinder-piston pair 10 arranged between the piston 3 and the connecting rod 4 , and the connecting rod 4 and the cylinder-piston pair 10 are connected through a connecting pin 6 . The same purpose and effect as in Embodiment 1 above can be achieved through the elasticity produced by the compression of the medium sealed in the cylinder-piston pair 10 . The medium sealed in the cylinder-piston pair 10 can be air, usable high-temperature-resistant liquid, or the like.

Embodiment 3

[0017] Embodiment 3: as image 3 As shown, the piston internal combustion engine of this embodiment includes a cylinder block 1, a cylinder head 2 arranged at the end of the cylinder block 1, a piston 3 and a connecting rod 4 connected to the piston 3, and the stroke distance of the piston 3 relative to the cylinder head 2 passes The variable travel device that is arranged on the connecting rod 4 adjusts. The stroke distance of the piston 3 relative to the cylinder head 2 is adjusted by changing the length of the connecting rod 4 at different strokes. The connecting rod 4 is composed of an upper connecting rod 8 and a lower connecting rod 9. The upper connecting rod 8 and the lower connecting rod 9 are slidably connected in the axial direction and are provided with an axial limit structure 11. Between the upper connecting rod 8 and the lower connecting rod 9 An elastic body 5 made of a spring is arranged between them.

Abstract

The present invention discloses a four-stroke piston internal combustion engine. It includes cylinder body, cylinder cap, piston and connecting rod. Said invention also provides their connection relationship and the working principle of said four-stroke piston internal combustion engine. Said invention can obtain three effects of raising engine powder, improving smoke-discharging condition and saving fuel.

Description

technical field [0001] The invention relates to a four-stroke piston internal combustion engine. Background technique [0002] At present, the strokes of the pistons of the existing four-stroke piston internal combustion engines used in the world are all fixed, and its working mode is completed by intake-compression-combustion work-exhaust four stroke cycles. This existing piston internal combustion engine has a common shortcoming, that is, due to the existence of the combustion chamber, there must be a fixed minimum distance between the piston and the cylinder head of the cylinder, that is, a fixed volume space is reserved after air compression for The mixed gas of compressed air and fuel burns to complete the work of expansion. This fixed volume space is generally called combustion space or combustion volume. Since the stroke of the piston is fixed, the combustion space or volume is also fixed. Due to the existence of the above-mentioned combustion volume, during the exh...
