Methods for Removing Carbon Deposits of Ricardo Diesel Generator Set

Jun. 14, 2023

During the maintenance of Ricardo diesel generator set, the problem of removing carbon deposits is often encountered. For example, carbon deposits in Ricardo diesel generator set are mostly accumulated on valves, pistons and cylinder heads. The composition of carbon deposit in Ricardo diesel generator set is closely related to the structure of the engine, parts, fuel, types of lubricating oil, working conditions and working hours. Carbon deposit is a complex mixture composed of resin, asphaltene, tar, lubricant and carbon, which is formed under the action of high temperature due to the incomplete combustion of Ricardo diesel generator set fuel and lubricant during combustion.

These deposits affect the heat dissipation effect of some parts of Ricardo diesel generator set, worsen the heat transfer conditions, affect its combustion, and even lead to overheating and cracking of Ricardo diesel generator set parts. At present, mechanical cleaning, chemical, and electrolytic methods are commonly used to remove carbon deposits from the device. In order to improve the production efficiency of Ricardo diesel generator set, the electric drill can drive the wire brush to rotate through the flexible shaft when in use. This method is simple and commonly used in small maintenance units, but it is inefficient, easy to damage the surface of Ricardo diesel generator set parts, and difficult to remove the coking. It can also be used to remove the carbon deposit of Ricardo diesel generator set by injecting rock core debris.


Because the core chip of Ricardo diesel generator set is softer than metal and will deform when impacting parts, the surface of Ricardo diesel generator set parts will not produce scratches or scratches, and the production efficiency is also high. In this method, compressed air is used to blow the dried and crushed peaches, apricots and walnut shells of Ricardo diesel generator set to the surface of the parts with carbon deposits to destroy the carbon deposits and achieve the purpose of cleaning. Some precision machined parts cannot use chemical methods on the surface, but chemical methods can be used.


The parts of Ricardo diesel generating set are immersed in the cleaning solution of sodium hydroxide and sodium carbonate at 80-95 ℃, the oil is dissolved or emulsified, and the coke becomes soft. After about 2-3 hours, remove the coke with a brush, wash the coke with hot water containing 0.1% -0.3% Potassium dichromate, and finally dry it with compressed air. Alkali solution is used as electrolyte by electrochemical method. Under the combined action of chemical reaction and hydrogen stripping, the workpiece of Ricardo diesel generator set is connected to the cathode to remove carbon deposits.
