The harm of the plugging of the nozzle:

1. The blockage of the needle valve and valve hole of the nozzle affects the performance of the precision components of the electronic injection system and leads to the decline of the dynamic performance.

2, due to poor fuel injection, the nozzle is not working well, so that carbon deposition is serious in cylinder, and cylinder and piston ring are accelerated wear, resulting in idle speed instability, fuel consumption rising, accelerating weakness, starting difficulties and excessive emissions, which will completely block fuel injector and damage the engine.
