Abstract

The utility model discloses a cylinder liner and piston ring for automobile engine, which comprises a cylinder liner body and a piston ring body, the utility model is characterized in that, the inside surface of the cylinder liner body is plated with a diamond film layer, the outside surface of the piston ring body is also plated with a diamond film layer, said diamond film layer covers the whole inside surface of cylinder liner body and the whole outside surface of the piston ring body uniformly, thickness of said diamond film layer is 2-3 micron, the utility model is characterized in that, compared with engine that uses common cast iron piston ring and cylinder liner in prior art, the utility model can relieve friction between the piston ring and the cylinder liner in cylinder, reduce wear consumption, increase engine power, reduce gas discharge, save energy, extend engine service life, and can be used extensively in various types of motor vehicle.

Description

Diamond film air cylinder sleeve of engine and piston ring

Technical field

The utility model relates to motor car engine, relates to the cylinder liner and the piston ring of motor car engine specifically.

Background technique

At present, it is increasing that the petroleum-based energies that Motor Vehicle consumed such as the annual automobile in the whole world, motorcycle account for the ratio of world energy sources total flow, and the waste gas of its discharge also is one of reason that directly threatens environment for human survival, how to reduce the automobile energy consumption, reduce exhaust emission pollution is the problem that the various countries scientist studies for a long period of time always.

Motor is the heart of Motor Vehicle, the body of motor is made up of component such as cylinder block, cylinder head, head gasket and cylinder sleeves, the cylinder block internal surface is a cylinder cylindraceous, cylinder is for the piston acting, realizes the vitals of Conversion of energy, and the working surface that contacts with piston in the cylinder generally is castiron inner core, be set on the cylinder, be called cylinder liner, reciprocating motion of the pistons mainly is directly to contact the relative movement in postpartum with cylinder sleeve by piston ring.

For the piston ring on the piston, general top two is compression ring, below one be oil ring, the effect of compression ring is to prevent that the gas or the waste gas that break out from missing, the effect of oil ring is to wipe the lubricant oil that remains on the cylinder wall off, and two kinds of piston rings generally also are to adopt the cast iron manufacturing.

Piston ring directly contact with cylinder liner and relatively at a high speed, prolonged exercise, violent friction, therefore all be easily damaged parts, for prior art, because piston ring and cylinder liner generally adopt through heat treated cast iron materials, so its frictional power loss is bigger, account for 1/3rd of the total frictional power loss of motor, therefore how alleviating friction and reducing wearing and tearing is to improve engine power, increase the service life important by way of, also be to be worth the research improvements.

The content of innovation and creation

The purpose of this utility model is at the deficiencies in the prior art, a kind of cylinder liner and piston ring of motor car engine are provided, the structure that the utility model adopts, friction between piston ring and the cylinder liner is alleviated, attrition reduces, and improves the power of motor, lowers gas emission, energy saving prolongs motor working life.

The technical solution of the utility model is such: cylinder liner and piston ring that a kind of motor car engine is provided, comprise cylinder liner body and piston ring body, it is characterized in that, be coated with one deck diamond film layer on the internal surface of cylinder liner body, and also being coated with one deck diamond film layer on the outer surface of piston ring body, described diamond film layer evenly coats cylinder liner body total inner surface and piston ring body whole outer surface.

According to the utility model of said structure, its feature is that also the thickness of the diamond film layer of cylinder liner body internal surface and piston ring body outer surface is the 2-3 micron.

The utility model according to said structure, its beneficial effect is, compare with the use plain cast iron piston ring of prior art and the motor of cylinder liner, the utility model can make the friction between piston ring and the cylinder liner alleviate, and attrition reduces, and improves the power of motor, lower gas emission, energy saving prolongs motor working life, can be widely used on various types of Motor Vehicle.

Embodiment

In conjunction with Fig. 1, Fig. 2, shown in Figure 3, cylinder block 1 is provided with cylinder liner body 2, piston 4 is provided with piston ring body 3, cylinder liner of the present utility model and piston ring, comprise cylinder liner body 2 and piston ring body 3, it is characterized in that, be coated with one deck diamond film layer 5 on the internal surface of cylinder liner body 2, and also being coated with one deck diamond film layer 5 on the outer surface of piston ring body 3, described diamond film layer 5 evenly coats cylinder liner body 2 total inner surface and piston ring body 3 whole outer surface.

According to the utility model of said structure, its feature is that also the thickness of the diamond film layer 5 of cylinder liner body 2 internal surfaces and piston ring body 3 outer surfaces is the 2-3 micron.
