具有碗部的活塞
摘要：
本发明公开了一种具有碗部的活塞，根据本发明的示例性实施方式，该活塞内部形成有唇缘倾斜表面，该唇缘倾斜表面沿着中心轴线方向从活塞的上表面的边缘倾斜；其中：从唇缘倾斜表面的端部部分形成有底部边缘凹槽；所述底部边缘凹槽的凹槽内部表面具有从中心轴线沿着外部方向形成为曲线的形状；底部边缘凹槽的凹槽底部表面具有沿着下方向形成为曲线的形状；唇缘倾斜表面和所述底部边缘凹槽形成为围绕中心轴线而置于中心，从而形成碗部；并且碗部的底部表面突出来，以形成对应于中心轴线的抬升部分。因此，根据本发明的内部形成有碗部的活塞增大了该碗部中形成的火焰的使用率，并进行稳定的燃烧，且控制了燃料喷射从而增加混合率。
摘要（英）：

The invention discloses a pistion having a bowl part. According to the embodiment of the invention, a lip-edge inclined surface is formed in the piston. The lip-edge inclined surface inclines from the upper surface of the piston along a direction of the central axis. An end part of the lip-edge inclined surface is provided with a bottom edge groove. The inner surface of the bottom edge groove is provided with a shape of a curve formed from the central axis along an external direction. The bottom surface of the bottom edge groove has a shape of a curve forming along a lower direction. The lip-edge inclined surface and the bottom edge groove surround the central axis and are disposed in the center, thereby forming the bowl part. And the bottom surface of the bowl part protrudes to form a rising part relatively to the central axis. Thus, by using the piston having the bowl part in the invention, the utilization ratio of fire formed in the bowl part is improved, thereby facilitating stable burning. And the spraying of fuel is controlled, thereby increasing the mixing rate.
