Example Embodiment

[0015] Example 1: Such as figure 1 As shown, the piston internal combustion engine includes a cylinder block 1, a cylinder head 2, 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 on the piston 3. The variable stroke device between and connecting rod 4 is adjusted. The variable stroke 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. 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 provided on the piston 3 or the connecting rod 4 as long as the thrust direction of the elastic body 5 is to push the piston 3 against the cylinder head 2. The elastic body 5 is generally made of ...

Example Embodiment

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

Example Embodiment

[0017] Example 3: Such as image 3 As shown, the piston internal combustion engine of this embodiment includes a cylinder block 1, a cylinder head 2, a piston 3, and a connecting rod 4 connected to the piston 3 at the end of the cylinder block 1. The stroke distance of the piston 3 relative to the cylinder head 2 passes The variable stroke device set on the connecting rod 4 is adjusted. 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 provided with an axial limiting structure 11, and the upper connecting rod 8 and the lower connecting rod 9 are An elastic body 5 made of a spring is arranged between.

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...
