Abstract
Provided is a cylinder liner having a first portion with a first thermal conductivity and a second portion with a second thermal conductivity. The first portion having the first thermal conductivity can include as-cast projections or a coating of a material, as desired. The first thermal conductivity can be greater than the second thermal conductivity. In this manner, the cylinder liner can exhibit a thermal conductivity gradient.
Claims19
A cylinder liner having varied thermal conductivity comprising:
- a cylindrical body;
- an outer surface of the cylindrical body;
- a first portion on the outer surface of the cylindrical body, the first portion disposed adjacent a top end of the cylindrical body, the first portion defining a first circumferential portion of the cylindrical body, the first circumferential portion including greater than half a height of the cylindrical body, the first portion having a first thermal conductivity;
- and a second portion on the outer surface of the cylindrical body, the second portion disposed adjacent a bottom end of the cylindrical body, the second portion defining a second circumferential portion of the cylindrical body, the second portion having a second thermal conductivity, the first thermal conductivity being greater than the second thermal conductivity.
