Futian Xiangling Cold Start Emission Reduction Monitoring Low Idle Fault

What you want to ask is what is the reason for the low idle failure of Futian Xiangling's cold start emission reduction monitoring? The reasons for the low idle failure of Foton Xiangling's cold start emission reduction monitoring are as follows.

1, the fuel injection quantity of injector is uneven, and the fog is not good, which leads to the power imbalance of each cylinder, which makes the idle speed of engine cold machine too low and leads to the unstable idle speed.

2. If the fuel pressure is too low, the fuel sprayed by the fuel injector is in poor atomization state, and the sprayed fuel is linear. In severe cases, only oil droplets are injected, and the fuel injection quantity is reduced, which makes the mixture too thin, which makes the idle speed of the engine too low when it is cold, resulting in unstable idle speed.

3. The temperature sensor, oxygen sensor and circuit did not reflect in time, which led to the control unit issuing wrong instructions, making the fuel injection amount incorrect, causing the mixture to be too rich or too thin, making the engine idle too low in cold state, leading to unstable idle speed.

4. Solution: Go to a professional repair shop and ask professionals to clean and dredge the oil and gas paths in the car, check the throttle valve, choke valve, acceleration pump and vacuum pump, and adjust them to the best state to ensure normal idle operation in severe cold.
