Engine cylinder wall striation device for use with motor vehicle, has mechanical device with digital control device that controls movements of head so that laser beam proceeds to non uniform laser beam scanning of internal wall

摘要

The device has a generator that generates a laser beam and a head (30) that projects and focuses laser beam on an internal wall. A mechanical device has a digital control device that controls the movements of the head so that the laser beam proceeds to a non uniform laser beam scanning of the wall.
