International Classification:

B08B 3/00

US Classification:

134 34, 134105

Abstract:

A cleaning system for use with a heat exchanger includes a fluid pressurizing assembly, a wand assembly and a movement mechanism configured to selectively move the wand assembly about a pivot axis. The wand assembly includes a first wand positioned adjacent to the heat exchanger and in fluid communication with the fluid pressurizing assembly, a second wand positioned adjacent to the first wand and in fluid communication with the fluid pressurizing assembly, and a mounting assembly defining the pivot axis. The first and second wands each have a first orifice configured to eject fluid toward the heat exchanger, and the first and second wands are both attached to the mounting assembly such that first and second wands both pivot together relative to the pivot axis.

International Classification:

Abstract:

A diesel exhaust fluid (DEF) storage system may include a reservoir body having a magnet integrally formed about an inlet opening of the reservoir body. For example, the magnet may be molding about a perimeter of the inlet opening during a molding process in which the reservoir body is formed. In some examples, the inlet opening defines a lumen extending into an interior of the reservoir body with the magnet being positioned at a location along the lumen opposite an external end face. The position of the magnet may be effective to engage a corresponding magnet on a DEF fill nozzle, allowing DEF to be introduced into the reservoir body. By integrating the magnet into the reservoir body, protection features that prevent erroneous filling of the reservoir body cannot be removed or bypassed.
