20090172943 | Process for finishing internal combustion engine cylinders using cold working - A new method for internal combustion engine cylinder finishing is proposed. Techniques for engine bore out, cylinder finish, and metal sleeve replacement have been developed for internal combustion engines. Separately, mandrel pull-through cold-working methods for fatigue life improvement have existed for holes with cracks. However, despite the decades old technology, mandrel pull-through cold-working has not been applied as the critical step in engine cylinder finishing. The first filing for the invention was provisional patent application 60883908 for “Cold-working application in combustion engines” submitted by the inventor on 8 Jan. 2007. This invention provides multiple techniques for applying mandrel pull through technology to cylinders that experience the hot, high cycle environment found in internal combustion engine cylinders. The method of employing cold-working as a critical step in engine cylinder finishing forms the basis for all claims listed. | 07-09-2009 |
