How many kilometers does Jiangling Kerry need to clean the throttle, fuel injector and ternary purifier? Can the throttle clean itself? How to clean the nozzle and the three Cui Yuan.

1. It is recommended to wash the throttle once a month.

2. Clean the fuel injector every 5,000 kilometers, without disassembly, and you can use the diesel system cleaner (DIY added to the fuel tank). As for the brand, that's your choice.

3. Jiangling Kerry should be a diesel vehicle without a three-way catalyst.

4. A large amount of carbon black after diesel combustion will dissolve in the engine oil of diesel vehicles during driving (the color of engine oil replaced by diesel vehicles is super black), so the engine lubricating oil circuit should be cleaned every time the engine oil is changed.

5. The air filter should be cleaned frequently, because the air quality is not good, so should the "mask".
