Abstract

An engine decarbonizing system comprises a manifold with one central and four lateral bores. Pressurized air and decarbonizing fluid in separate containers are adapted to be co-mingled and fed to and through the manifold. A tube assembly has an output tube and two parallel input tubes operatively coupled. The output tube is coupled to the central bore and the two parallel input tubes are coupled to the containers for dispensing pressurized decarbonizing fluid. Four short tubes are coupled to the lateral bores and second ends have a rigid cylindrical nozzle selectively positionable within a spark plug for the delivery of a spray of pressurized decarbonizing fluid. Four switches are coupled to the manifold adjacent to the interface between a short tube and a short bore for selectively allowing or precluding the flow of decarbonizing fluid.

Claims

1. An engine decarbonizing system for decarbonizing internal combustion engines in an efficient and simplified manner comprising, in combination:

a manifold in a generally rectilinear configuration with two small parallel end faces and four large rectangular side faces and with one long linear cylindrical central bore extending inwardly from one end face and four short linear cylindrical lateral bores extending from the central bore to an adjacent side face;

pressurized air in a container along with decarbonizing fluid adapted to be fed to and through the manifold;

a flexible elongated tube assembly having an output end and input end, the tube being coupled to the central bore and with the input end being coupled to the pressurized air and the decarbonizing fluid of the container for dispensing pressurized decarbonizing fluid to and through the manifold;

four flexible short tubes with first ends respectively coupled to the lateral bores and second ends each having a rigid cylindrical nozzle selectively positionable within a spark plug opening of an internal combustion engine to be decarbonized for the delivery of a spray of pressurized decarbonizing fluid;

four switches, each switch individually coupled to the manifold adjacent to the interface between a short tube and a short bore for selectively allowing or precluding, at the discretion of a user, the flow of decarbonizing fluid from the manifold to an associated nozzle and spark plug opening as a function of the number of spark plug openings to receive decarbonizing fluid;

a rigid generally cylindrical suction guide tube having an interior end with exterior threads adapted to be threadedly received within each spark plug opening of an engine to be decarbonized and having an input end with a frusto-conical configuration spaced from the interior end and having an intermediate section there between, the suction guide adapted to guide the entry of the probe into the spark plug openings;

a suction assembly having a base beneath and a handle above, the suction assembly also having an air pump positioned on the base with inlet tubing to create a vacuum and outlet tubing to exhaust air, the suction assembly also having a can removably positioned on the base and operatively coupled between the inlet and outlet tubing to collect suctioned decarbonizing fluid fed through the tubing from the manifold, the suction assembly also including an elastomeric probe with limited flexibility having a linear long section coupled to the inlet tubing and a linear short section with an obtuse angle of about 270 degrees there between, the short section adapted to be inserted through a guide tube into a spark plug opening for withdrawing the decarbonizing fluid from the engine; and

a supplemental cleaning assembly for projecting a spray of supplemental cleaning liquid through the intake manifold of an engine after an initial decarbonizing, the supplemental cleaning assembly having a flexible tube with an input end coupled to a pressurized supply of supplemental cleaning liquid and with an output end and a rigid plate couplable to the engine adjacent to the intake manifold of an engine and with a spray head positioned within the intake manifold on the side of the plate remote from the tube for the spraying of supplemental cleaning liquid into the manifold, the rigid plate being formed with two laterally spaced arcuate sections with bolt holes there through for securement to an engine spanning the intake manifold and with an upper arcuate section of an enlarged diameter and a lower arcuate section of a reduced diameter.

2. An engine decarbonizing system comprising:

a manifold with one central bore and four lateral bores;

pressurized air in a first container and decarbonizing fluid in a second container adapted to be co-mingled and fed to and through the manifold;

a tube assembly having an output tube and two parallel input tubes operatively coupled, the output tube being also coupled to the central bore and the input tubes coupled to the containers for dispensing pressurized decarbonizing fluid;

four short tubes coupled to the lateral bores and second ends each having a rigid cylindrical nozzle selectively positionable within a spark plug hole or opening for the delivery of a spray of pressurized decarbonizing fluid; and

four switches coupled to the manifold adjacent to the interface between a short tube and a short bore for selectively allowing or precluding the flow of decarbonizing fluid.

3. The system as set forth in claim 2 and further including:

a suction assembly having a base beneath and a handle above, the suction assembly also having an air pump positioned on the base with inlet tubing to create a vacuum and outlet tubing to exhaust air, the suction assembly also having a container positioned on the base and operatively coupled between the inlet and outlet tubing to collect suctioned decarbonizing fluid fed through the tubing from the manifold, the suction assembly also including an elastomeric probe with limited flexibility having a linear long section coupled to the inlet tubing and a linear short section with an obtuse angle there between, the short section adapted to be inserted through a guide tube into a spark plug opening for withdrawing the decarbonizing fluid from the engine.

4. The system as set forth in claim 2 and further including:

a rigid generally cylindrical suction guide tube having an interior end adapted to be received within each spark plug opening of an engine to be decarbonized and having an input spaced from the interior end and having an intermediate section there between.

5. The system as set forth in claim 2 and further including:

a supplemental cleaning assembly for projecting a spray of supplemental cleaning liquid through the intake manifold of an engine after an initial decarbonizing, the supplemental cleaning assembly having a flexible tube with an input end coupled to a pressurized supply of supplemental cleaning liquid and with an output end and a rigid plate couplable to the engine adjacent to the intake manifold of an engine and with a spray head positioned within the intake manifold on the side of the plate remote from the tube for the spraying of supplemental cleaning liquid into the manifold, the rigid plate being formed with laterally spaced arcuate sections for securement to an engine spanning the intake manifold and with an upper section and a lower.
