Description

Technical Field

[0001] The utility model relates to the field of single-cylinder engines, in particular to a vertical small-sized single-cylinder engine cylinder body. Background Art

[0002] Existing small single-cylinder diesel engine products have occupied a certain share in the market, especially in the field of agricultural machinery. Most of these products use a universal cylinder block, which is designed as a horizontal inclined structure, mainly to adapt to the spatial layout and power requirements of small agricultural machinery. In this design, the vortex combustion chamber is widely used.

[0003] However, this universal cylinder block also has problems with vibration and noise: due to the asymmetric layout of the horizontal inclined structure, the center line of the cylinder hole has a 25° angle with the vertical direction, which causes unbalanced force on the cylinder block and vibration when the cylinder block runs at high speed, affecting the balance of the vehicle. These small diesel engines generate large vibrations and noise during startup and use, affecting the comfort of the operator.

[0004] Furthermore, the inclined bar hole takes up a large amount of space. The side of the cylinder block is originally the installation position for peripheral accessories. The inclined bar hole makes it impossible to install accessories on one side of the bar hole, so the space cannot be fully utilized, and the limited space in the engine hood is wasted.
