Title:
CYLINDER BLOCK FOR INTERNAL COMBUSTION ENGINE AND ITS MACHINING METHOD
Document Type and Number:
Japanese Patent JP2004036511
Kind Code:
A
Abstract:

To manufacture a cylinder bore controlling the decrease in circularity even during the operation of an internal combustion engine.

This method of machining a cylinder block for the internal combustion engine comprises heating the cylinder block up to a preset temperature and then applying honing work for the cylinder bore. The circularity of the cylinder bore is secured in the state of the cylinder block being thermally expanded, thereby the circularity of the cylinder bore is greatly improved during actually operating the internal combustion engine.
