How to deal with unqualified idle speed during automobile inspection?

Replace the spark plug and clean the fuel injector.

The ignition energy of spark plug is not enough to completely burn the mixture, which leads to the HC content in the exhaust gas exceeding the standard. In addition, the nozzle atomization is not good, and the mixed gas is too thick, which will lead to the waste gas not passing. Replacing the spark plug and cleaning the nozzle can solve the problem.

Before the vehicle inspection, using fuel additives to clean the vehicle once can effectively reduce the exhaust emission, thus achieving the purpose of passing the inspection. The effect of reducing emissions of hydrocarbons and carbon monoxide is particularly remarkable.

It can clean and maintain fuel and exhaust system components, such as catalytic converter, diesel particulate filter, oxygen sensor, exhaust valve, piston, combustion chamber and so on. Moreover, gasoline, diesel and hybrid vehicles can be used safely, which has obvious effects on reducing fuel consumption, improving power, reducing emissions and repairing engine performance.

Precautions:

1. Regularly and thoroughly clean the intake branch pipe, intake and exhaust valves, combustion chamber, oxygen sensor and three-way catalytic converter to remove carbon mud dirt from beginning to end.

2. Replace the fuel filter regularly. Replace the fuel filter every 10000- 15000 km or every three months. In addition, diesel vehicles should also maintain the fuel oil-water separator.

3. Change the oil regularly. Engine oil mainly plays the role of lubrication, cleaning, cooling, rust prevention and corrosion protection in the engine. So you can consider changing the oil every 5,000-8,000 kilometers or every 6 months.

4. Clean the fuel injector and spark plug regularly. Every 15000 km, the fuel injector and spark plug should be cleaned, and the platinum spark plug can be appropriately lengthened according to the combustion situation.
