Introduction to L28/32 Diesel Engine Parts: Treatment Methods for Carbon Deposits on Engine Cylinder Heads

When removing carbon deposits from aluminum alloy parts such as pistons and straight cylinder heads, a cleaning solution can be prepared by mixing 20 grams of sodium carbonate, 8 grams of sodium silicate, 10 grams of soap, 5 grams of potassium dichromate, and 1000 grams of water. Heat the solution to 70℃-80℃, then immerse the parts in the cleaning solution for about 30 minutes until the carbon deposits soften and can be removed. Rinse and dry with hot water.

Metal cleaner is a highly effective carbon remover with strong scale removal capacity. To enhance the removal effect on parts with severe carbon deposits, other components can be added to the metal cleaner to prepare a solution. The formula is as follows: 40 grams of metal cleaner, 12 grams of sodium hydroxide, 12 grams of sodium silicate, 12 grams of sodium pyrophosphate, 10 grams of sodium tripolyphosphate, and 1000 grams of water. Heat to 70℃-80℃ and soak to remove.
