Has the problem of carbon deposition in Fit been solved?

First of all, all engines will have the problem of carbon deposition, but more or less. The 1.5 self-priming engine used in Fit is Honda Earth Dream series products. This engine adopts direct injection technology, which makes it easier for the engine to form carbon deposits on the intake and valve back. This is a characteristic of direct injection engines, which is easy to happen in all direct injection engines. If you just want to buy this Fit car, don't worry too much about this problem, which is basically within 65,438+10,000 kilometers. Drive normally, if there is carbon deposit, just clean it up. It is different from the position where the throttle is easy to deposit carbon. The throttle needs to be cleaned separately, usually once every 20,000-40,000 kilometers. This is not necessarily related to carbon deposition.
