14th generation sylphy clean throttle carbon deposit.

Sylphy suggests cleaning up carbon deposits every two years or 40 thousand kilometers. In fact, there is no accurate suggestion on the cleaning frequency of carbon deposits, which mainly depends on driving habits and driving environment. When cleaning up carbon deposits, it is basically demolition-free cleaning, and the cost is between 300-500 yuan. Only in the case of serious carbon deposition, choose the method of opening the cylinder head throttle and cylinder block. Generally, vehicles with serious carbon deposits will have these situations, and it is difficult to start the cold car; Idle speed is unstable, tachometer is unstable and accompanied by strange jitter noise; Cylinder knocks, and there will be abnormal sound when accelerating at low speed; Acceleration is weak, overtaking is difficult, fuel consumption rises, the car feels fleshy than before, and fuel consumption is higher than normal.

Nissan Sylphy carbon cleaning projects mainly include the following four types:

Cleaning the throttle valve: remove the engine decorative cover, remove the throttle valve, clean it with carburetor cleaner, dry it with cotton cloth and install it. This project can be carried out by itself, because the process of cleaning the throttle is very simple and the cost is extremely low. Just buy a bottle of carburetor cleaner.

Clean up the carbon deposit inside the engine: open the engine oil cover, pour in the whole tank of cleaning agent (mixed with the old engine oil), cover the engine oil cover, and turn off the engine after the ignition idling 10 minutes. Clean the carbon deposit inside the engine. This cleaner can dissolve the deposits such as sludge, colloid, moisture and metal debris inside the engine, reduce the pollution of new engine oil and prolong the service life of the engine.

Clean up the carbon deposit in the oil circuit: before refueling, add the whole bottle of fuel additive to the fuel tank. Cleaning the carbon deposit in the oil circuit includes cleaning the fuel injector, combustion chamber, spark plug, throttle and other parts.

Cleaning the carbon deposit in the air intake system: pour the cleaning agent of the air intake system into the liquid storage tank of special cleaning equipment, connect the air intake system, and suck the cleaning agent into the air intake through vacuum during driving to achieve the cleaning purpose. Cleaning the carbon deposit in the intake system mainly refers to cleaning the carbon deposit in the intake and intake manifold.
