If the fuel nozzle is atomized excessively, the fuel may not be injected into the combustion chamber normally, thus affecting the normal operation of the engine. Here are some possible solutions:

1. Cleaning nozzle: The fuel nozzle may be affected by deposits and dirt, resulting in poor injection effect. You can use a special nozzle cleaner or remove the nozzle for cleaning to remove the accumulation.

2. Check the normal working voltage of the nozzle: The normal working voltage of the fuel nozzle is very important. Check whether the nozzle voltage is normal to ensure the correct intensity and time of fuel injection.

3. Check the oil pressure: If the oil pressure is too low, the fuel injection will not be strong enough. You can check the oil supply system to ensure that the oil pump works normally and the oil pressure is stable.

4. Check the fuel filter: the fuel filter filters out foreign objects and impurities. If the filter is blocked, it will affect the supply and quality of fuel, and then affect the spraying effect. The fuel filter can be checked and replaced regularly.

5. Check the nozzle throat: the nozzle throat is the channel to guide the fuel into the nozzle. If the throat is blocked, it will affect the normal work of the nozzle. Special tools can be used to clean throat passages.

If none of the above methods can solve the problem, it is recommended to consult a professional automobile maintenance technician for inspection and maintenance to ensure that the problem is solved correctly.
