Motor vehicle window glass cleaning method, involves applying fluid stored in tank on window glass, and operating pump in discontinuous manner to allow discontinuous application of fluid on window glass by projection elements

摘要

The method involves applying fluid stored in a tank (1) on a window glass (2) by a pump (3) according to a reference cleaning cycle activable by a controller provided with main and secondary inspecting devices (4, 5). An engine (8) is operated with rotation speed lower than reference rotation speed to allow sweeping of the window glass. The pump is operated in a discontinuous manner to allow discontinuous application of the fluid on the window glass by projection elements (11). The engine is operated in a continuous way to allow continuous sweeping of the window glass by brushes. The fluid is water mixed with a component i.e. alcohol. An independent claim is also included for a windscreen wiper system for a window glass of a motor vehicle.
