Method for producing internal surface of cylindrical barrel of cylinder casing of heat engine of car, involves positioning cylinder casing on support in working position in which casing rests on support via tablature plane

摘要

The method involves positioning a cylinder casing (1) on a support (10) in a working position in which the casing rests on the support via a tablature plane (P2). Aeraulic connection process is performed to connect an end (11) of a cylindrical barrel (4) with a circular window (25) of the support. A lower mask (28) is fitted inside the window with respect to a lower aspiration device (26) and equipped with a bell mouth (29). An injector channel (8) is equipped with an upper mask (16). A circular end (23) of an aspiration pipe (22) of the upper mask is made of flexible plastic. An independent claim is also included for a cylinder casing.
