Embodiment Construction

[0029] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0030] In the present disclosure, the orientation words "inner and outer" used refer to the contours of the corresponding components unless stated otherwise.

[0031] like figure 1 As shown, the engine provided by the present disclosure includes a cylinder block and a crankshaft, and the cylinder block includes a cylinder 2, a cylinder liner 3 sleeved in the cylinder 2, and a piston 4 reciprocating in the inner wall of the cylinder liner 3, between the piston 4 and the crankshaft A connecting rod is connected, specifically, a piston pin 5 for connecting with a connecting rod 7 is fixed on the piston 4 , furthermore, the crankshaft 1 has a crank throw, and th...

Abstract

The invention relates to an engine and a vehicle. The engine comprises a cylinder body and a crankshaft. The cylinder body comprises an air cylinder (2), a cylinder sleeve (3) arranged in the air cylinder (2) in a sleeved mode and a piston (4) making reciprocating motion in the inner wall of the cylinder sleeve (3). A connecting rod is connected between the piston (4) and the crankshaft. The inner wall and the outer wall of the cylinder sleeve form an eccentric structure so that the relative position of the piston (4) and the air cylinder (2) can be adjusted when the cylinder sleeve (3) rotates. When the cylinder sleeve of the engine rotates in the air cylinder, the piston can make axial motion in the cylinder sleeve as the position of the connecting rod is basically kept unchanged, so that the relative position of the piston and the cylinder sleeve can be adjusted, and the compression ratio of the engine is changed.

Description

technical field [0001] The present disclosure relates to the technical field of automobiles, and in particular, relates to an engine and a vehicle. Background technique [0002] For internal combustion engines, the higher the compression ratio, the higher the thermal efficiency. However, as the compression ratio increases, the engine will produce knocking, which will reduce the output of the internal combustion engine and cause damage to the internal combustion engine. The existing engine adopts a fixed compression ratio, but due to the limitation of knocking, the compression ratio cannot be increased, and when the load is low, the thermal efficiency decreases and the economy is poor. Contents of the invention [0003] An object of the present disclosure is to provide an engine that can adaptively adjust the compression ratio according to different working conditions of the engine. [0004] Another object of the present disclosure is to provide a vehicle using the engine ...
