How effective is the controversial fuel treasure in removing carbon deposits?

With the rapid development of China's economy in recent decades, our life has become more and more affluent, so cars, once an absolutely high-value commodity, have gradually entered the homes of ordinary people, bringing a lot of convenience and comfort to our lives;

However, with the comprehensive popularization of automobiles, a problem that comes with it is the lack of knowledge of vehicle maintenance by riders. Especially in recent years, the demonized carbon deposit theory once made many riders full of fear of this kind of carbon deposit. In this case, all kinds of fuel additives naturally play a leading role in removing carbon deposits, and business opportunities stem from riders' fear of carbon deposits. Because of this, various fuel additive products have emerged in an endless stream in recent years, and riders also regard it as a panacea. And is it accurate to say that carbon deposition is the root of all evil? Is it as scary as what is rumored outside?

The main component of carbon deposit is the carbonized product of incomplete combustion of fuel. In fact, incomplete combustion of carbon-containing fuels will produce so-called carbon deposits, such as gasoline, diesel, alcohol, natural gas, water gas and so on. Because the combustion efficiency of our internal combustion engine can't reach 100%, there must be some fuels that can't be completely burned, and this part of incomplete combustion residue is the main component of carbon deposition.

The remaining components of carbon deposit are some minerals and metal additives in engine oil; Some impurities in gasoline (oil); There are silicate particles in the air, which is closely related to air quality. Silicate particles are very hard, so after being sucked into the engine to form a pile, it is easy to damage the internal seal of the engine, which will reduce the engine performance in advance or produce burning oil. In a word, the causes of carbon deposition are composed of many aspects, but the production of carbon deposition is inevitable.

Clean fuel treasure: Clean fuel treasure is a very old term. As early as the 1960s, there was a cleaner (polyisobutylene succinimide) for carburetor engines, but this is an old story. With the development of these twenty years, there are two main engine cleaners, PIBA and PEA；.

Actually, there is still a generation gap. PIBA was formed earlier, and it was mainly used for EFI (Electronically Controlled Manifold Injection). Because its composition is not very resistant to high temperature, its function is more suitable for removing carbon deposits on the back of the intake valve and the intake manifold of the EFI engine, because the fuel of the EFI engine is sprayed in the manifold (where the fuel is sprayed, it has a cleaning effect in theory), and this composition is not suitable for removing carbon deposits in the combustion chamber.

Because of the poor gasification ability of PIBA in high temperature environment, it is easy to solidify due to the extremely high temperature in the cylinder, forming new carbon deposits; Therefore, if the fuel treasure containing this component is used too frequently, more and more carbon will be deposited in the combustion chamber. It is an early cleaning product, and now it is basically eliminated, and EFI engines are rare in the market.
