Does mixed injection affect the cleaning of throttle valve?

Cleaning the throttle is mainly

Remove the plastic heat shield from the engine, remember the location of the pipeline, and then remove the throttle.

Wear gloves and a mask, dissolve the carbon deposit with solvent, and dry it with a towel after 1 ~ 2 minutes.

Idle running for 2 ~ 3 minutes is enough.

Secondly, there are two main types of engines.

One is a hybrid injection engine, and the other is a direct injection engine.

The fuel nozzle of in-cylinder direct injection engine is in the engine cylinder. After the fuel nozzle of this engine sprays gasoline, some gasoline will adhere to the cylinder wall or piston top, and carbon deposit will be formed after heating.

Mixed injection engine can effectively reduce carbon deposition.

Therefore, mixed injection can reduce the cleaning of throttle valve.
