Title: Cylinder block
Inventor: KASAHARA KOJI
IPC: F02F1/10
Filed: 2008-07-14
Abstract: <P>PROBLEM TO BE SOLVED: To improve the roundness of a cylinder bore at the time of an actual operation of an engine in a cylinder block wherein a cylinder liner is insert-casted.  <P>SOLUTION: The cylinder liner 3 form of cast iron is insert-casted in a cylinder block body 2 formed of an aluminum alloy. A recess is reduced by forming a padding section 9 on the recess of a connection section of a cylinder wall 5 wherein the adjacent cylinder liner 3 is insert-casted at this time. Then, the cylinder bore 4 of the cylinder liner 3 is finished at a real circle by machining. When insert-casting the cylinder liner 3, residual strain caused by a difference of thermal expansion between the cylinder block body 2 and the cylinder liner 3 is equalized by arranging the padding section 9. Therefore, when the residual strain is released by a temperature rise at the actual operation of the engine, the fourth-order deformation of the cylinder bore 4 is relieved, and the roundness can be improved.  <P>COPYRIGHT: (C)2010,JPO&INPIT
