Abstract

The invention discloses an anti-cavitation and environment-friendly cylinder sleeve, which comprises a cylinder sleeve body, wherein water channel wall reinforced structures are arranged on water channel walls of the cylinder sleeve body, and comprise reinforced sleeves arranged surrounding the peripheral faces of the wall channel walls; the inner circumferential faces of the reinforced sleeves are fixedly connected with wall faces of the water channel walls; the peripheral faces of the reinforced sleeves are arranged to be conical surfaces; the connecting parts of the conical surfaces and the wall faces of the water channel walls are in smooth transition; washers are arranged on the lower end faces of support shoulders of the cylinder sleeve body, and are arranged on the cylinder sleeve body in a sleeving way. According to the anti-cavitation and environment-friendly cylinder sleeve provided by the invention, the integral rigidity of the cylinder sleeve is increased, and the vibration of the cylinder sleeve during operation is reduced, so that the anti-cavitation performance is realized.

Description

technical field [0001] The invention relates to the field of automobile engines, in particular to a cavitation-resistant environment-friendly cylinder liner. Background technique [0002] The cylinder liner is a cylindrical part, which is placed in the cylinder block hole of the machine body, and is pressed and fixed by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water outside. The functions of the cylinder liner are: 1. Together with the cylinder head and the piston, it forms the working space of the cylinder. 2. The cylinder liner of the cylindrical piston diesel engine bears the side thrust of the piston and becomes the lead of the reciprocating motion of the piston. 3. Transfer the heat of the piston assembly and itself to the cooling water to make it work at an appropriate temperature. 4. The cylinder liner of the two-stroke diesel engine is provided with an air port, which is opened and closed by the piston to realize ai...
