Sinopec Hailong Fuelbao trademark map is as follows. Sinopec Hailong, fuel treasure Hailong and fuel treasure used in gas stations are automobile fuel additives. The clean fuel cleaner developed by North China Company and Sinopec Sales Company in the early 199s is mainly composed of metal-free polymer and ashless surfactant. The main component of fuel treasure is a polymer ashless surface active substance. This polymer surfactant dissolved in automobile fuel has strong adsorption, wetting, solubilization and dispersion functions, which can make the carbon deposited on the metal surface disintegrate, fall off and disperse into fine carbon micelles. These oil-soluble fine carbon micelles enter the combustion chamber together with fresh mixed gas to burn, and some unburned carbon deposits are discharged into the atmosphere with tail gas. This is the working principle of Long Fubao. A large number of vehicle bench tests and driving tests in fuel treasure show that frequent use of fuel treasure can effectively remove the deposits in the intake system of automobile engines, keep the intake system clean and the spark plug clean. Thereby reducing the maintenance cost of the fuel intake system and prolonging the service life of the vehicle.
