How to clean up the carbon deposit in Volkswagen Tiguan

There are three specific methods to remove carbon deposits in Tiguan;

(1) Open cylinder for cleaning

Encountering too thick carbon deposit has obviously endangered the normal operation of the engine, so this method has to be adopted. However, if you go to a small processing plant for engineering construction, you must consider it comprehensively. Because liquid detergent is usually used for immediate cleaning, we will not conduct professional inspection to see if it is discharged, the liquid state cannot be reduced, and the crankshaft will be forced to bend when the engine is running.

② Gasoline can also remove carbon.

Aiming at the engine spewing from the manifold, gasoline itself is a good organic solution, which can play the role of cleaning on the way and achieve the practical effect of self-cleaning. The gasoline sprayed by the injector enters the cylinder according to the air inlet and intake valve, and the carbon deposit will be cleaned in this process, which plays a cleaning role. The direct injection engine injects gasoline and diesel directly into the engine combustion chamber, so it is impossible to clean the cylinder and air intake, which is often a high-risk area for carbon deposition in direct injection engines. However, now the oil in gas stations already contains cleaning additives, so the following measures must be taken to assist carbon deposition.

③ Fuel additives

In view of the fact that the carbon deposit in the cylinder is not obvious, gas stations or automobile 4S shops will generally introduce fuel additives to people in detail, and the carbon deposit can be simply and directly eliminated by filling up the automobile fuel tank before fuel supply! Is it really so wonderful? Therefore, we conducted a simple test on Loeb oil duct cleaning kit which just entered the China sales market not long ago.
