Accompanying drawing explanation
The structural representation of the cylinder sleeve that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with Figure of description, the embodiment of cylinder sleeve, supercharged engine and vehicle that the utility model embodiment provides is described.
Cylinder sleeve embodiment:
See Fig. 1, there is shown a kind of preferred structure of the cylinder sleeve that the utility model embodiment provides.This cylinder sleeve may be used for supercharged engine.As shown in Figure 1, the inwall of this cylinder sleeve can be provided with reticulate pattern 1, and reticulate pattern 1 can be the shape that is staggered shown in Fig. 1, wherein, the Rvk (paddy is dark, and namely roughness center profile is to the mean depth of the profile trough of solid material) of reticulate pattern can be 1.2um-2.0um.During concrete enforcement, the Rvk of reticulate pattern can elect 1.2um, 2.0um as, certainly, also can select arbitrary numerical value therebetween, such as 1.5um, 1.7um etc.
In the present embodiment, Rvk due to inboard wall of cylinder liner reticulate pattern is in the scope of 1.2um-2.0um, that is, on the inwall of cylinder sleeve, meeting quantity of formation is more, the groove that size is narrower and darker, in the working procedure of motor, a certain amount of fluid can be stored in the groove of inboard wall of cylinder liner, these fluid can supply the working surface of inboard wall of cylinder liner in time, the speed that inboard wall of cylinder liner rebuilds oil film will be greater than fluid by the speed extruded from cylinder sleeve, therefore the inwall of cylinder sleeve can be covered by oil film always, and then enhance the bearing capacity of cylinder sleeve, decrease the wearing and tearing of cylinder sleeve, also reduce the upper string quantity of cylinder inner engine oil simultaneously, improve the oil storage capacity of cylinder sleeve, ultimately improve the performance of motor.
In above-described embodiment, the Mr2 (trough profile bearing length ratio) of reticulate pattern 1 can be 73%-83%.During concrete enforcement, the Mr2 value of reticulate pattern 1 can select 73%, 80%, 83% etc.The angle of reticulate pattern 1 can be 25 °-35 °.During concrete enforcement, the angle of reticulate pattern 1 can be the numerical value such as 25 °, 30 °, 35 °.The Rk (the roughness core profile degree of depth) of reticulate pattern 1 can be 0.2um-0.8um.During concrete enforcement, the Rk of reticulate pattern 1 can be 0.2um, 0.6um, 0.8um etc.The Rpk (namely peak height exceedes the profile crest average height of center peak valley height) of reticulate pattern 1 can be 0.2um-0.4um.During concrete enforcement, the Rpk value of reticulate pattern 1 can be 0.2um, 0.3um, 0.4um etc.
In above-described embodiment, reticulate pattern 1 can be cross hatch.When carrying out Honing process to the inwall of cylinder sleeve, generally comprise three steps, be followed successively by slightly sew with long stitches, half essence is sew with long stitches and essence is sew with long stitches, by these three steps, the surface quality of processing rear inboard wall of cylinder liner can be ensured preferably, make each parameter of reticulate pattern 1 be in suitable scope, improve the oil storage capacity of cylinder sleeve, to reduce the oil consumption of motor.
In the present embodiment, for diameter be 81mm, cylinder sleeve circularity is 0.08mm, cylinder sleeve cylindricity is 0.012mm, the Rvk of reticulate pattern 1 be 1.2um-2.0um, Mr2 is 73%-83%, angle is 25
0-35
0, Rk to be 0.2um-0.8um, Rpk be 0.2um-0.4um cylinder sleeve test, according to the fuel consumption data that 5 motors being provided with this cylinder sleeve obtain through overtesting, the cylinder sleeve provided in the present embodiment is provided, when completing the endurance test of 800 hours, the average fuel consumption of motor is 17g/h.When completing the cold shock testing of 400 hours, the oil consumption of motor also only has 12g/h, and supercharged engine of the prior art, it is no matter the endurance test of 800 hours, or the cold shock testing of 400 hours, the fuel consumption of the motor that the fuel consumption of its motor all provides considerably beyond the present embodiment, therefore the supercharged engine that the present embodiment provides significantly reduces oil consumption, reduce the pollution that exhaust emissions causes air, greatly increase the reliability of motor.
