Description

[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 647,417, filed May 14, 2024, and U.S. Provisional Patent Application No. 63 / 715,406, filed November 1, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to an applicator or applicator and system for cleaning a vehicle internal combustion engine via an intake manifold. Background Technology

[0003] Gasoline direct injection (“GDI”) engines typically utilize fuel injection technology, which, over time and with operation, leaves various deposits on the engine's intake valves. While fuel injection technology offers advantages and efficiency, it produces carbon and other deposits that accumulate on the intake valves, reducing airflow and thus decreasing engine performance, including higher emissions, lower power output or horsepower, poorer fuel economy, and generally rougher engine performance. Additional damage can occur if the accumulated deposits detach and move through the system, causing damage to other components or other performance degradation. Therefore, it is necessary to remove the dirt and deposits.

[0004] Existing methods of physically cleaning intake valves require professional service and are expensive. Numerous chemical cleaners, such as those in U.S. Patents 2,943,945 and 8,627,845, are known for addressing the problem of cleaning intake valves. In addition to chemical cleaners, applicator devices or applicator systems can also be used to enable vehicle owners to apply chemical cleaners to vehicle intake valves. For example, U.S. Patents 10,267,227, 11,585,267, and 11,773,770 provide alternative solutions for cleaners and applicators. However, such applicators and cleaners each have drawbacks, and improvements are needed, whether concerning environmental issues or the difficulties encountered by a single person attempting to apply the cleaner to their own vehicle in their own garage or driveway using an applicator. Improved applicators and cleaners are needed to enable one-handed application of cleaners to remove dirt and deposits from intake valves, assisting vehicle owners in engine maintenance. Summary of the Invention

[0005] This application provides an applicator, system, and method for cleaning engine deposits from intake valves in a GDI engine. The applicator includes an outer housing for housing a delivery conduit and has an outlet for fluid connection to and guidance of the delivery conduit during operation. The outer housing also includes an actuator assembly that forms a connection with a pressurized canister containing a cleaning agent and allows the cleaning agent to be released from the canister. The outer housing has a base for snap-fit ​​attachment to the top of the pressurized canister above a valve stem, allowing fluid to flow from the canister after the user activates the actuator assembly. A surface extending outward from the base of the outer housing provides a shelf or base shelf for supporting the delivery conduit. The shelf may include a generally circular wall extending upward from the shelf, or a generally conical wall extending upward from the shelf. Each type of shelf allows the delivery conduit to be wound around or wrapped around the wall of the outer housing for storage. A delivery conduit of at least about 7 feet, and preferably at least about 10 feet, is provided.

[0006] The delivery conduit has a detergent or fluid receiving end and a detergent or fluid delivery end. The detergent delivery end engages and supports a delivery conduit support clip for securing the delivery conduit within the intake manifold. In any preferred embodiment, the delivery conduit is a flexible, elongated delivery conduit configured to be stored around or wrapped around an outer housing and for positioning the flexible, elongated delivery conduit as desired into the engine intake manifold. The delivery conduit may be provided to the consumer in conjunction with the actuator assembly, or may be connected by the consumer before use. A lock is also provided to ensure that the product is not accidentally or by a child. The dispenser further includes a cap or top cover for use during transport and storage to engage and cover the outer housing, delivery conduit, and support clip.

[0007] The elongated length and flexible structure of the delivery conduit, along with the delivery conduit support clamp, enable a single-handed operation of the applicator by a single user while seated in the driver's seat within the vehicle's passenger compartment, behind the wheels of the user's vehicle. The system and method, comprising the applicator and the cleaning agent within the canister, can be operated by a user located inside the vehicle while seated in the driver's seat, allowing the user to operate the vehicle while applying the cleaning agent using the applicator equipped with this system and method.

[0008] To use the system and method of the present invention, the elongated flexible delivery conduit and support clip are first opened by removing the top cover engaged on the outer housing. The support clip can then be engaged with the fluid delivery end of the delivery conduit, or the support clip can be configured to pre-assemble and support the delivery conduit beneath the top cover. The delivery conduit and support clip are then detached from their storage location around a shelf on the outer housing. After extending from the outer housing, the fluid delivery end of the delivery conduit and support clip can be easily accessed by the user from inside the vehicle via an open driver's door or window, under an open hood, to a desired location near the engine intake manifold. A vehicle engine valve chemical cleaner canister, interconnected with the delivery conduit, is held near the driver's seat position within the vehicle's passenger compartment. The user then secures the support clip, along with the delivery conduit, to the engine intake manifold at the location and point for receiving the fluid cleaner from the fluid delivery end of the delivery conduit into the intake manifold. The user can then return to the driver's seat position, grasp the vehicle engine valve chemical cleaner canister with one hand, and place their finger on the activation button trigger. Then, the user can start the vehicle engine with their second hand and increase the engine speed to a higher RPM, at least 2000-3500 RPM or higher, while pressing the applicator activation button trigger to deliver the cleaner to the engine intake manifold and dirty valves.

[0009] The delivery duct support clamp comprises a body having a top leg and a bottom leg interconnected by a web portion. The free ends of each of the top and bottom legs, positioned relative to the web portion, are configured to be close together to ensure engagement with a portion of the intake manifold. The web portion, as well as the top and bottom legs, are made of a sufficiently flexible material to allow the legs to move relative to the web portion to bend and secure the support clamp to the vehicle. An opening is provided on one of the legs of the support clamp, such as the top leg, for supporting engagement with the delivery duct.

[0010] The actuator assembly, secured within the outer housing, includes a valve for engaging with and receiving cleaning agent from the pressurized tank. Many prior art valve configurations are well known, and the valve of this invention can be formed as a separate valve or configured within an internal portion of a push-button trigger.

[0011] The system includes a pressurized tank for holding cleaning agent. The tank has an internal reservoir and an outlet port in fluid communication with the internal reservoir. The delivery end of a delivery conduit is in fluid communication with the fluid outlet of the applicator's outer housing, and since the system is typically a one-time operation, it is preferably permanently or non-removably secured to the fluid outlet of the outer housing using any known technique. The cleaning agent receiving end of the delivery conduit is in fluid communication with the fluid outlet of the outer housing via the tank's outlet port and a connected valve passage through which the cleaning agent flows from the tank.

[0012] The cleaning agent of the system of the present invention may comprise several components, such as detergent, water, and propellant. In this embodiment of the cleaning agent, the water-soluble properties of several components provide an advantage to the cleaning agent within the system. Test protocols show that the amount of water used in the cleaning agent effectively provides a steam cleaning process for the valve, helping to remove deposits from the intake valve surface and thereby improving engine performance.

[0013] The cleaning agent of the present invention for dispensing from a pressurized tank via a dispenser may comprise well-known commercially available cleaning agents, such as those available from Lubrizol Corporation. At least about 2.0% by weight of water may also be provided to ensure sufficient steam generation during operation of the method and system, to help clean the surfaces of the intake valves. Finally, a propellant, such as NP-70, may also be provided. Attached Figure Description

[0039] While the subject matter of this application may be embodied in many different forms, preferred embodiments and alternative embodiments are described herein. It should be understood that this disclosure should be considered as an example of the principles described and is not intended to limit the broad aspects described in the illustrated embodiments. It should be understood that this disclosure may be embodied in other specific forms without departing from the spirit or central characteristics of this disclosure. For the context, the orientation of a component may be referred to by the orientation shown in the figure (e.g., top, bottom, right, left, etc.). Similarly, apostrophes may be used to identify alternative forms of similar features. Those skilled in the art will recognize that these orientations may be changed during use without altering the relationships between the components. Therefore, embodiments of the invention should be considered illustrative rather than restrictive in all respects and should not be limited to the details given herein.

[0040] like Figure 1-2As shown in Figures 9-10 and 13, the applicator includes an outer housing 20 for housing a delivery conduit 40 and having a fluid outlet 22 for fluid connection with and guidance of the delivery conduit during operation. An actuator assembly 60 within the outer housing 20 forms a preferred permanent or non-removable connection to a pressurized canister PC containing cleaning agent C and allows the cleaning agent to be released from the canister. Such attachment may include adhesive, molding, crimping, press-fitting, or any known permanent or non-removable connection. The outer housing has a base 24 for snap-attaching to the top T of the canister PC above a valve stem 62, allowing fluid to flow out of the canister upon activation of the actuator assembly 60. A surface extending outward from the base 24 of the outer housing provides a shelf or base shelf 26 for supporting the delivery conduit 40. The shelf 26 may include a generally circular wall 28 extending upward from the shelf, or a generally conical wall 28' extending upward from the shelf. Each type of shelf 26' allows the delivery conduit 40 to be wound around or wrapped around the wall of the outer housing for storage. Preferably, a delivery conduit of at least about 7 to 10 feet is provided. The delivery conduit support clip 100 is configured to be pre-assembled onto the delivery conduit 40 or attached by the user.

[0041] The applicator may also include a cap or top cover 30 for engaging and covering the outer housing 20, the delivery conduit 40 having a detergent receiving end 41 and a detergent delivery end 42, and a delivery conduit support clamp 100 during transport and storage, such as Figure 1-2 As shown. Figures 15 to 20 As shown, the top cover may include a top flange 31, which has a reduced diameter compared to the portion of the top cover that engages with the outer housing. The top flange 31 facilitates convenient nesting and stacking of the product during transportation and retail. Figures 14 to 18 As shown, a ridge 32 is positioned at the base 24 of the outer housing below the shelf 26 for a press-fit or snap-fit ​​engagement of the top cover 30 with the outer housing 20. In any preferred embodiment, the delivery conduit 40 is configured to allow storage around or wrapped around the outer housing and to position the elongated delivery conduit as desired relative to an engine intake manifold with engine valves to be cleaned under the open hood of the vehicle. The delivery conduit 40 may be provided to the consumer in conjunction with the outer housing 40 and / or may be attached by the consumer before use, wherein the embodiments do not include a permanent or non-removable connection. A lock is also provided to ensure that the product is not accidentally fitted or fitted by a child.

[0042] The circular wall 28 has an outer diameter between 1.5 and 3.5 inches, and preferably approximately 2.5 inches so as to engage with and be surrounded by the delivery conduit 40 during storage. The top shelf 29 may also optionally be spaced apart from and above the base shelf 26 of the outer housing, as... Figures 1 to 8As shown. The base shelf preferably extends approximately 1.5 inches above the base. The top shelf 29 extends radially outward from a portion of the top of the wall 28 and is able to additionally restrict the delivery conduit 40 during storage without interfering with the operation of the actuator assembly 60. In the absence of the top shelf, spaced-out ears 29' may be provided, extending outward and away from the button trigger 64 of the actuator assembly 60, as shown. Figures 13 to 18 As shown. Ears 29' extending outward from the button trigger 64 are used to help capture and retain the delivery conduit when it becomes wrapped around the walls 28, 28' during product sale, storage, and delivery to consumers. The delivery conduit is wound and secured multiple times for storage between the base shelf and the top shelf or between the spaced-apart ears. For a delivery conduit 40 that is approximately 7.5 feet long, for example, it is typically provided to have 7 to at least 10 turns around the wall.

[0043] The delivery conduit 40 is preferably a flexible conduit with a length of at least 2 feet to 12 feet, more preferably at least 6 to 11 feet, and most preferably at least about 10 feet. The flexible delivery conduit 40 may be provided with an elongated wire guide 43, which is contained within the central channel 45 or embedded within a portion of the wall 44 of the delivery conduit. The manufacture of the delivery conduit 40 with the embedded wire guide 43 is typically carried out during the extrusion of the delivery conduit. The delivery conduit 40 has an inner diameter of approximately 1.6 mm and an outer diameter of approximately 2.6 mm, and is preferably made of polyethylene plastic or other suitable polymer material. While the embedded wire guide 43 is preferably provided along the entire length of the delivery conduit, alternatives, such as a shorter length of embedded wire guide (possibly along the central length of the delivery conduit, but leaving a gap at each end) or a shorter interval length, may also be sufficient. When the wire guide is contained within the central channel 45, the wire guide can simply be inserted and positioned within the length of the central channel, possibly fixed at one or both ends of the delivery conduit.

[0044] The delivery duct support clamp 100 comprises a body 102 having a top leg 104 and a bottom leg 106 interconnected by a web portion 108. The free ends 110 of each of the top and bottom legs, positioned relative to the web portion 108, are configured to be close together to ensure engagement with the intake manifold. The web portion 108, as well as the top and bottom legs 104 and 106, are made of a sufficiently flexible material to allow the legs to move relative to the web portion, thereby bending and securing the support clamp 100 to the vehicle. An opening or support 112 is provided on one of the legs of the support clamp 100 (e.g., the top leg 104) for supporting and ensuring engagement with the delivery duct 40. The delivery duct support clamp 100 is preferably made of a polyoxymethylene polymer material (also known as acetal, polyacetal, polyoxymethylene, or POM plastic), and is preferably a thermoplastic due to its stiffness, low friction, and dimensional stability, but other suitable polymer materials may be sufficient. Figures 1 to 8 The top support leg 104 shown includes a delivery conduit support 114, which can be configured as an open bracket 114 adjacent to the free end 110 of the top support leg to allow the delivery conduit to snap-fit ​​or otherwise press into a secure engagement with the delivery conduit 40. Figure 9-10 In one embodiment, the bottom support leg 106' is provided with an open bracket 114' support and an open blocking groove 115 to ensure engagement of the fluid delivery end 42' on the bottom support leg of the support clamp 100'. Figures 15 to 22 In one embodiment, the free end 110' of the top support leg 104" may include a closed hole or opening 114" in an alternative to the open bracket, through which the delivery conduit can be screwed to secure the delivery conduit to the support clamp 100". Figure 15-22 In one embodiment, the free end 110" of the top leg 104" is bent upward and away from the bottom leg 106", and the top surface 105 of the top leg may include a bracket for supporting a delivery conduit engaged with the top leg, or an opening adjacent to the web portion through which the delivery conduit can be screwed. Alternatively, the top leg may include a hose surround 116 spaced apart from the bracket toward the web portion for surrounding and supporting the fluid delivery end of the delivery conduit. Figure 10 and 15The bottom legs 106, 106', and 106" are shown. These bottom legs include serrations or ribs 117 for engagement with the engine intake manifold to resist removal of the support clamp during operation of the applicator, system, and method. The bottom legs, top legs, and web portion have a generally U-shaped configuration for engaging the support clamp by sliding the clamp and delivery conduit into engagement with the engine intake manifold in a delivery position. The design of the delivery conduit support clamp, made of a rigid yet flexible and stable material, allows for some expansion and contraction or spring action of the bottom and top legs, as well as between the bottom and top legs, during engagement with the engine intake manifold, using the web portion.

[0045] The fluid delivery end 42 of the delivery conduit 40 is in fluid communication with the fluid outlet 22 of the applicator outer housing 20, and when the system is generally a one-time operation, it is preferred to permanently or in an irremovable manner fix the outlet of the outer housing by any known technique, such as adhesive, molding or other equivalent techniques.

[0046] After the delivery conduit 40 and support clip 100 are secured to the engine intake manifold in the delivery position, the cleaner from the cleaner delivery end 42 of the delivery conduit is positioned to spray cleaner C into the engine intake manifold after a single user in the driver's seat position behind the vehicle's wheels activates the button trigger 64 of the actuator assembly 60. Figure 23 As shown in the diagram. During operation of the system and method, a single user is able to depress the accelerator pedal to increase engine RPM while simultaneously activating the applicator 10 to deliver cleaning agent C using the advantageous one-handed, one-user method and system operation. The disposable can PC of cleaning agent C is typically a can between 11 and 18 ounces. The fluid chemical vehicle engine valve cleaner C contained within the internal reservoir of the can is approximately 12 ounces in an 18-ounce can that also contains propellant and water.

[0047] Valve 200 forms a channel 202 configured with a valve stem 62, an inlet 204, and an outlet 206 to allow fluid communication of detergent C from the pressurized tank PC to the outer housing outlet 22 and the interconnecting delivery conduit 40. When the user's finger compresses the outer surface 66 of the button trigger and the internal trigger return spring (not shown), activating the button trigger 64 to operatively engage the shoulder 208 on the internal portion 65 of the button trigger 64 with the valve stem 62 of the tank C in the valve open position, the valve channel 202 receives a flow of detergent from the tank PC. The outer surface of the button trigger includes ribs 67 for easy operation. The actuator assembly 60 includes a trigger return spring to bias the button trigger from engagement with the valve stem of the tank to the closed position. The button trigger 64 with the valve channel 202 can be of any suitable shape made of any suitable material, such as injection-molded rigid plastic or polymer. A button trigger recess 68 is provided in the outer housing 20 at a location opposite the outer housing outlet 22 for fluid connection with the delivery conduit 40.

[0048] exist Figures 14 to 21 In one embodiment, the delivery conduit guide groove 69 may be formed to surround the fluid outlet 22 of the applicator outer housing 20, thereby enabling vertical movement and guidance of the attached delivery conduit 40 within the guide groove 69 during user activation of the button trigger 64. The guide groove 69 in the illustrated embodiment has a vertically elliptical configuration, an open top portion, and is located at the front of the outer housing 20 opposite the button trigger recess 68. In an embodiment with a top shelf 29, the guide groove interrupts the top shelf, as... Figure 5 As shown in the diagram. In an embodiment with an extended ear 29', a guide groove 69' is located at the front of the outer housing opposite the extended ear. A delivery conduit 40 extends from the outlet 22 of the outer housing 20 through the guide groove 69. Alternative configurations of the fluid outlet 22 of the outer housing 20 may also be provided.

[0049] The applicators, systems, and methods described herein are further described in the appended claims and can be varied in many ways. Such variations should not be considered a departure from the spirit and scope of the statements herein, and all such modifications, which will be apparent to those skilled in the art, are intended to be included within the scope of the described configuration.
