Long term prevention: 5 management strategies personally taught by engineers

1. Fuel quality control: Establish a three-level inspection system for fuel entering the factory (with three checkpoints for sulfur content ≤ 15ppm/10ppm/5ppm), and after the implementation of this system, the DPF blockage rate of a certain logistics fleet decreased by 79%

2. Driving mode optimization: Through data monitoring by the onboard ECU, it was found that the temperature rise rate of DPF during rapid acceleration is 4.7 times faster than during smooth driving. Suggest installing an intelligent driving assistance system to control the frequency of rapid acceleration to ≤ 12 times per month

3. Air filter synergy: Adopting a composite air filtration system (AC-2000 type) can reduce the concentration of particulate matter entering the DPF by 68%. Actual test data shows that this configuration extends the regeneration cycle by 2.3 times

4. Regular maintenance calendar: Establish a "3-7-15" maintenance cycle (30000 kilometers of cleaning prediction, 70000 kilometers of deep maintenance, 150000 kilometers of system upgrade), and a truck manufacturing plant reduced maintenance costs by 55% after application

5. Environmental adaptability plan: Develop a special plan for high-altitude areas (altitude>2000 meters), including increasing the number of pre catalysts, optimizing the EGR exhaust gas recirculation ratio, and adjusting 12 parameters
