Abstract
An arrangement for an internal combustion engine includes a crank case, a cylinder liner disposed in a cylinder of the crank case and including a flange, and a cylinder head disposed on an end of the cylinder delimiting a combustion zone inside the cylinder liner, wherein the flange of the cylinder liner is braced between the cylinder head and the crank case, wherein a flange cooling cavity is provided, which is delimited by a circumferential surface of the flange of the cylinder liner and the cylinder head.
Claims20
A system, comprising
- a crank case having a cylinder;
- a cylinder liner disposed in the cylinder of the crank case, wherein the cylinder liner comprises a flange, and
- a cylinder head disposed on an end of the cylinder delimiting a combustion zone inside the cylinder liner,
- wherein the flange of the cylinder liner is braced between the cylinder head and the crank case, wherein a flange cooling cavity is disposed directly between and in fluid communication with a first outer circumferential surface of the flange of the cylinder liner and the cylinder head, and the flange cooling cavity extends over a radial distance between the first outer circumferential surface and an inner circumferential surface over a circumferential distance about a longitudinal axis of the cylinder liner.

A method, comprising:
- flowing a cooling medium through a flange cooling cavity disposed directly between and in fluid communication with a first outer circumferential surface of a flange of a cylinder liner and a cylinder head, wherein the cylinder liner is disposed in a cylinder of a crank case, the cylinder head is disposed on an end of the cylinder delimiting a combustion zone inside the cylinder liner, the flange of the cylinder liner is braced between the cylinder head and the crank case, and the flange cooling cavity extends over a radial distance between the first outer circumferential surface and an inner circumferential surface over a circumferential distance about a longitudinal axis of the cylinder liner.
A system, comprising:
- a body portion of an internal combustion engine, comprising:
- a cylinder in the body portion;
- a flange recess in the body portion, wherein the cylinder is configured to receive a cylinder liner having a flange disposed in the flange recess;
- and
- a flange cooling cavity disposed at least partially along the flange recess, wherein the flange cooling cavity extends over a radial distance directly between a first outer circumferential surface of the flange and an inner circumferential surface of the body portion over a circumferential distance about a longitudinal axis of the cylinder liner.
