Abstract
Disclosed is an apparatus and application tool useful for removing engine deposits in a reciprocating internal combustion engine by directing a substantial portion of a cleaning composition to an interior cavity of the engine through an access port wherein the point of delivery is independent of the access port and positionable within the interior of the engine cavity.
Claims20
An apparatus for administering a cleaning solution to an interior surface of a reciprocating engine system comprising an elongated conduit in fluid communication with a treatment manifold adapted for positioning into the interior of a reciprocating engine cavity through an access port, said treatment manifold having a bore therethrough and at least one maneuverable end portion having an orifice for directing fluid delivery to an interior surface of said engine requiring cleaning, wherein the treatment manifold is of sufficient length such that the orifice is positionable independently of the location of the access port, and a seal member circumscribing and in cooperation with said treatment manifold to releaseably engage with the access port of the engine.
An apparatus for delivering a cleaning composition to multiple independent interior surfaces of an engine system requiring cleaning comprising an elongated conduit in fluid communication with a treatment manifold adapted for insertion into the interior cavity of a reciprocating engine through an access port, said treatment manifold having a central bore in communication with a plurality of orifices disposed on said central bore and extending radially outward therefrom, said orifices positionable along the central bore to provide a plurality of discrete delivery points for substantially directing the cleaning composition to a plurality of preselected interior engine surfaces independent from the location of the access port, and a seal member circumscribing and cooperating with said treatment manifold to releaseably engage with the access port of said engine.
An apparatus for delivering a cleaning composition to an interior surface of an engine system comprising an elongated conduit in fluid communication with a treatment manifold adapted for insertion into the interior cavity of a reciprocating engine through an access port, said treatment manifold having a plurality of independently directible tubes having a passageway therethrough and at least one orifice disposed on each tube for a discrete point of fluid delivery, said tubes having proximal and distal ends, wherein the proximal ends are in communication with a seal member, and at least one distal end of a tube positionable to an interior surface to be cleaned.
An application tool attachable to an air intake system of an internal combustion engine for administering and directing a cleaning composition to remove interior carbonaceous engine deposit comprising:
- (a) a pressure resistant reservoir container having an inlet in communication with a pressure regulator and a discharge outlet, said container charged with an engine cleaning composition,
- (b) an adjustable valve connected to the discharge outlet of the pressure resistant reservoir container,
- (c) at least one elongated conduit having a proximal end and a distal end with a bore extending throughout, the proximal end being connectably attached to the adjustable valve for receiving the engine cleaning composition discharged from the pressure resistant reservoir container upon actuation of the valve,
- (d) a treatment manifold in fluid communication with the distal end portion of the at least one elongated conduit, the treatment manifold adapted for insertion into the interior cavity of the engine through an access port within said engine, said treatment manifold having at least one directable tube with an orifice for fluid delivery extending within the interior engine cavity from the access port, a guide member concentric to a portion of the directable tube for positioning said orifice in proximity to a surface to be cleaned, and
- (e) a seal member which is releasably engagible with the access port and cooperates with the elongated conduit and treatment manifold to allow for transport of fluid therethrough.
