In general, engines or transmissions of vehicles, aircraft, ships, agricultural machines, etc., are assembled with many parts. It is very important to do

In order to remove carbon from carbon-deposited parts, after heat treatment (gas torch, etc.) of the carbon-attached surface, the primary carbon is removed using a metal brush, and then soaked in a water bath containing an acidic cleaning solution for a certain period of time, followed by a soft brush Then, the secondary carbon removal work using the molten metal or the removal work using an airbrush or high-pressure water is carried out.

In particular, to wash parts (scavengers, cylinder heads, etc.) that are mixed with high-viscosity tar, oil, and carbon, remove large foreign substances attached to the surface as much as possible manually. After performing the soaking operation in a temperature water bath (acidic solution, solvent, etc.), the surface of the soaked product is cleaned by a secondary manual operation using an air brush or high-pressure water.

Recently, parts that have been primarily manually washed are being washed using an automatic washing machine having a structure similar to that of a dishwasher. That is, high-pressure water is sprayed from a rotary nozzle attached to a small water tank, and parts are washed using this.

However, due to the large fluctuation of the cleaning rate according to the complexity of the structure of the parts, the follow-up work of the operator is increasing and it is difficult to achieve a 100% cleaning rate.
