Internal combustion cleaning

1. A scraping tool for cleaning a combustion chamber of an internal combustion engine, comprising:

at least one scraper;

a longitudinal carrier;

an actuator; and

a passage inside the at least one scraping tool to remove a combustion residue from the combustion chamber;

wherein the at least one scraper is configured to clean at least one surface of the combustion chamber; wherein the longitudinal carrier connects the at least one scraper with the actuator; wherein the at least one scraper is adjustable between a first configuration for introducing the at least one scraper through a bore in a cylinder head into the combustion chamber and a second configuration for cleaning the at least one surface of the combustion chamber.

2. The scraping tool according to claim 1 , wherein the actuator comprises a handle, wherein a motion of the at least one scraper can be driven by hand.

3. The scraping tool according to claim 1 , wherein the actuator comprises a connection interface for a rotary drive, wherein a motion of the at least one scraper can be driven by the rotary drive.

4. The scraping tool according to claim 1 , wherein the scraping tool is configured for a rotational motion and/or longitudinal motion for scraping.

5. The scraping tool according to claim 1 , wherein the at least one scraper has a scraping surface.

6. The scraping tool according to claim 1 , wherein the at least one scraper has a grinding surface.

7. The scraping tool according to claim 1 , wherein the at least one scraper comprises a wire brush.

8. The scraping tool according to claim 1 , wherein the at least one scraper is replaceable.

9. The scraping tool according to claim 1 , further comprising a wire connected to the at least one scraper leading through or on the longitudinal carrier to the actuator, wherein the wire is configured to move the at least one scraper between the first configuration and the second configuration.

10. The scraping tool according to claim 9 , wherein a pivot joint is disposed in an intermediate position between opposite ends of a unitary body of the at least one scraper.

11. The scraping tool according to claim 1 , further comprising a conduit connected to the passage, which can be used to remove the combustion residue from the combustion chamber, with a suction apparatus.

12. The scraping tool according to claim 1 , further comprising a stop fixed on the longitudinal carrier to determine a position of the at least one scraper inside the combustion chamber.

13. A method for cleaning a combustion chamber of an internal combustion engine comprising:

introducing at least one scraper of a scraping tool through a bore in a cylinder head into the combustion chamber, wherein the scraping tool comprises a longitudinal carrier coupled to the at least one scraper, a stop fixed on the longitudinal carrier to determine a position of the at least one scraper inside the combustion chamber, and an actuator coupled to the longitudinal carrier, wherein the at least one scraper is adjustable between first and second configurations relative to the longitudinal carrier, and the at least one scraper fits through the bore in the first configuration;

adjusting the at least one scraper from the first configuration to the second configuration inside the combustion chamber; and

cleaning at least one surface of the combustion chamber by moving the at least one scraper in the second configuration against the at least one surface.

14. The method according to claim 13 , wherein the at least one surface comprises an interior head surface of the cylinder head inside the combustion chamber, and/or an interior wall surface of the combustion chamber, and/or an upper surface of a piston of the internal combustion engine.

15. The method according to claim 13 , further comprising after cleaning, moving a piston away from the cylinder head; and removing a combustion residue produced by the cleaning.

16. The scraping tool according to claim 1 , wherein the at least one surface comprises an interior head surface of the cylinder head inside the combustion chamber, and/or an interior wall surface of the combustion chamber, and/or an upper surface of a piston of the internal combustion engine.

17. The scraping tool according to claim 1 , wherein the at least one scraper is disposed substantially parallel to the longitudinal carrier in the first configuration, and the at least one scraper is disposed at an angle between 10° and 170° with respect to the longitudinal carrier in the second configuration.

18. A scraping tool for cleaning a combustion chamber of an internal combustion engine, comprising:

at least one scraper configured to couple to a longitudinal carrier having an actuator;

wherein the at least one scraper is adjustable between a first configuration and a second configuration via a single wire coupled to the at least one scraper and driven by the actuator, the at least one scraper comprises a pivot joint at an intermediate position between opposite ends of the at least one scraper, the at least one scraper is configured to pass through a bore in a cylinder head into the combustion chamber in the first configuration, and the at least one scraper is configured to clean at least one surface of the combustion chamber in the second configuration.

19. The scraping tool according to claim 18 , wherein the at least one scraper comprises a unitary body configured to rotate about the pivot joint between the first and second configurations, and the intermediate position is a center position between the opposite ends.

20. The scraping tool according to claim 18 , comprising the longitudinal carrier having the actuator, wherein the at least one scraper is removably coupled to the longitudinal carrier.

21. The scraping tool according to claim 18 , comprising a passage inside the scraping tool to remove a combustion residue from the combustion chamber.

22. The scraping tool according to claim 18 , comprising a stop to determine a position of the at least one scraper inside the combustion chamber.
