AI Technical Summary

Technical Problem

Existing diesel vehicle fuel cleaning technologies cannot adapt to dynamic changes in engine operating conditions, resulting in delayed or excessive cleaning. Furthermore, they lack quantitative assessment of the synergistic corrosion effects of multiple contaminants, impacting component lifespan and maintenance costs.

Method used

By acquiring fuel quality data and vehicle operating parameters through a sensor array, calculating dynamic cleaning thresholds, determining pollution levels using a multi-pollutant synergistic effect index, selecting the optimal cleaning action based on a reinforcement learning Q-value table, and adjusting cleaning intensity using PID feedback, adaptive cleaning control is achieved.

Benefits of technology

It improves the accuracy and robustness of cleaning threshold determination, optimizes cleaning effect and energy consumption, extends component life, and reduces maintenance costs.

Abstract

The invention belongs to the technical field of vehicle cleaning, and particularly relates to a fuel oil cleaning method and system for a diesel vehicle, and the method comprises the steps: obtaining fuel oil quality data through a sensor array installed on the diesel vehicle, collecting whole vehicle working condition parameters, and calculating a dynamic cleaning threshold value corresponding to each fuel oil quality data based on the whole vehicle working condition parameters; according to the method, real-time working condition parameters such as the engine rotating speed, the torque, the air inlet temperature and the load power are fused, the cleaning threshold values of sulfur, water and impurities are dynamically calculated, a safety verification and correction mechanism is introduced, the problem of misjudgment or response lag of a traditional fixed threshold value strategy under complex working conditions such as high altitude, low temperature or heavy load is effectively solved, and the method is suitable for large-scale popularization and application. And the accuracy and robustness of threshold judgment are remarkably improved.
