An exhaust component assembly for a vehicle exhaust system includes a housing defining an internal cavity configured to receive an exhaust gas after-treatment component. A first chamber is in fluid communication with the internal cavity upstream of the exhaust gas after-treatment component. A first nozzle introduces fluid into the first chamber and a first valve controls flow of the fluid from the first chamber into the internal cavity. A heat source is associated with the first nozzle or first chamber. A second chamber is in fluid communication with the internal cavity upstream of the exhaust gas after-treatment component, and the second chamber is a non-heated chamber. A second nozzle introduces fluid into the second chamber and a second valve controls flow of the fluid from the second chamber into the internal cavity. A controller controls the first and second valves based on at least one predetermined operating condition.

A vehicle cleaning system that can be manufactured to integrate with an existing motor vehicle or as part of a new vehicle manufacture, providing a convenient automated method of cleaning a large motor vehicle such as a trailer or RV. The vehicle cleaning system can be implemented by delivering water from either an independent valve running to an onboard cleaning system; a water line connection; or from an onboard holding tank which may contain water or other cleaning agents, to a valve system operating a series of extrusion nozzles. The cleaning system may have one or more manual or electromechanical pumps and a manual or electromechanical valve system to actuate at least one cleaning cycle, or to activate the operation of the vehicle cleaning system in specific zones along the body of a vehicle. The vehicle cleaning system may operate by means of a roof-mounted actuated piping and nozzle system or an extrusion nozzle spray system having recessed extendable nozzles, or an integrated nozzle system.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system uses a treatment unit for spraying fluid at agricultural objects. The treatment unit is configured with a treatment head assembly that includes a moveable treatment head with one or more spraying tips. A first and second motor assembly are operated by the treatment unit to control the movement of the treatment head. The first motor assembly includes a first motor rotatable in a first rotational axis. A first linkage assembly is connected to the first motor and the treatment head assembly. The first linkage assembly is rotatable by the first motor. The second linkage assembly is rotatable by the second motor.

A wiping device includes a rod, a spraying assembly, a base, and a translation module. The wiping paper is wound around the rod. The spraying assembly comprises a nozzle. The nozzle is arranged above the rod, and the nozzle is arranged towards the wiping paper. The base is used for fixing a workpiece. The translation module is coupled to the rod or the base. When the rod rotates around an axis of the rod, a wiping paper is wound around the rod. The nozzle could spray a cleaning agent to the wiping paper, then, the translation module could drive the rod and the base to move relatively, and the wiping paper wetted by the cleaning agent wipe the workpiece. The cleaning agent could wet the outermost layer of the wiping paper directly, so that the amount of the cleaning agent could be reduced.

A treatment system, including a conveyor bed configured to transport a plurality of products; a brushing device located along the conveyor bed and having one or more brushes that include a first antimicrobial compound; a surface treatment device including a lamp configured to emit light of a peak wavelength directed toward a portion of the conveyor bed; and a coating device configured to deliver a coating mixture onto the plurality of products on the conveyor bed.

A fluid application system includes a manifold defining an internal passageway for fluid flow therethrough and a plurality of nozzle assemblies connected in fluid communication with the internal passageway. Each nozzle assembly of the plurality of nozzle assemblies includes a body defining a fluid passage, an inlet connected to the manifold for receiving fluid flow into the fluid passage, and a spray outlet for discharging fluid from the fluid passage. Each nozzle assembly also includes an electrically actuated valve fluidly connected between the inlet and the spray outlet and configured to control fluid flow through the fluid passage. Each nozzle assembly further includes a pressure dampener connected in fluid communication with the fluid passage upstream of the electrically actuated valve. The pressure dampener is configured to dampen fluctuations in fluid pressure within the fluid passage.

A manually-operated trailer wash apparatus for washing an interior of a trailer includes a frame with a handle configured to be manually pushed by a human operator and front and rear wheels. Rotatable couplings are disposed between each of the wheels and the frame to rotate the wheels in response to the manual pushing of the handle. A conduit is coupled to the frame and extends transversely across a direction of travel of the apparatus. The conduit has a plurality of nozzles to pressure wash a surface on which the apparatus travels. The conduit receives pressurized fluid from a hose and pump system.

The invention relates to an apparatus for the binding of dust, comprising a binder reservoir, which provides liquid binder which is under pressure, a binder line which is connected to the binder reservoir, wherein there is connected to the binder line at least one spray nozzle which may be located in the vicinity of a dust source. The apparatus is in particular so designed that large areas, which may extend over distances of several 100 m, may be supplied with binder, which may also be discharged, with these dimensions, in pulses at short intervals (1 second up to a few minutes).

A substrate processing apparatus includes a cover member placed to surround a substrate held by a rotary holder; a collecting member placed in an exhaust path formed between the cover member and the rotary holder; and a solvent supply placed above the collecting member and configured to supply a solvent to the collecting member. The solvent supply includes an inner storage space surrounding the substrate; an outer storage space surrounding the inner storage space; and a partition wall extending along a circumferential direction to partition the inner storage space and the outer storage space. Multiple communication holes are extended to penetrate the partition wall such that the solvent introduced into the outer storage space flows to the inner storage space. Multiple dripping holes are extended to penetrate a bottom wall of the inner storage space such that the solvent within the inner storage space drops toward the collecting member.

A spraying system and method is provided for more efficiently accessing the interior of a container having an access opening to the container that is offset from or in angular relationship to the center and/or rotational axis of the container to contact the interior walls and surfaces of the container with a medium, such as a liquid, mixture, solution or suspension. The spraying system and method includes a non-linear boom that is elevated by a support structure, where the non-linear boom includes at its front end a plurality of spray nozzles. In one example, the support structure is a movable support structure that includes a guide mechanism where the guide mechanism is mounted on the moveable support structure at an angle relative to the surface supporting the moveable support structure to allow access to the interior of the container.
