Does Shoubao need to clean the engine iron filings?

There's no need to keep cleaning. Oil lubrication is filtered through the oil filter element, so it is enough to replace the oil filter regularly. Even if it is cleaned, it is best to run 1 and 2000 km to replace the oil filter again, so as to avoid the influence of cleaning agent residue on the performance of the oil.

The throttle of the engine is disassembled and washed once for 20,000 to 30,000 automatic gears. The feeling of manual gears is not obvious, and the problem is not great after a long time;

As for the oil circuit of the injector, there is basically no special requirement, and replacing the gasoline filter element on schedule is the key.

Extended data:

As a kind of machinery, engine has the same requirements for lubricating oil as general machinery, such as proper viscosity, certain performance requirements such as oxidation resistance, wear resistance, corrosion resistance and viscosity temperature. But the engine is a special kind of machinery, and its requirements for lubricating oil have its own special side, and its particularity mainly includes:

1) The general requirements for the engine are small volume, light weight, compact mechanism and high output power, so it bears a great load on the unit friction surface.

2) Besides the friction heat, it is also affected by the combustion heat, so the temperature of the friction surface is very high, which reduces the viscosity of the lubricating oil and is not easy to form an oil film.

3) The high-temperature and high-pressure combustion gas in the combustion chamber will leak into the crankcase through the gap between the piston, piston ring and cylinder liner. These combustion gases are gases and some particles (smoke and dust) produced by complete combustion and incomplete combustion of fuel oil and a small amount of lubricating oil, which usually become the main components of crankcase blowby, and will pollute lubricating oil and promote its oxidation under certain conditions.
