Carbon cleaning machine for cleaning deposited carbon of automobile engine

The invention relates to the technical field of carbon cleaning devices, in particular to a carbon cleaning machine for cleaning deposited carbon of an automobile engine. The carbon cleaning machine can effectively reduce the content of water vapor in gas, improve the purity of the gas and avoid the influence of the water vapor on the combustion state of the gas by drying oxyhydrogen gas exhaustedinto the automobile engine, and is convenient for full combustion of the oxyhydrogen gas in the engine to improve the carbon cleaning effect and improve the practicability and reliability. The carboncleaning machine comprises a water tank, four sets of support legs, a cover plate, a water outlet pipe, a water outlet valve and a U-shaped pipe; the four sets of support legs are mounted at the bottom of the water tank; the left front side of the top of the water tank communicates with a water injection port; the cover plate covers the water injection port; the water outlet pipe is mounted on the front lower side of the
