Abstract

A scraping tool for cleaning a combustion chamber of an internal combustion engine is provided. The scraping tool includes at least one scraper unit, a longitudinal carrier, and an activation device. The at least one scraper unit is configured to clean at least one surface of a cavity. The longitudinal carrier, preferably a rod or a tube, connects the at least one scraper unit with the activation device. The at least one scraper unit is swivel mounted on the longitudinal carrier and can be swiveled from a first position for introducing the at least one scraper unit into the cavity to a second position for cleaning at least one surface of the cavity. In the first position, the at least one scraper unit is disposed substantially parallel to the longitudinal carrier. In the second position, the at least one scraper unit is disposed at an angle between 70° and 110°, preferably between 80° and 100°, and more preferably at substantially 90°, with respect to the longitudinal carrier.
