AI Technical Summary
Existing technologies cannot fully explain the difference between actual fuel consumption of motor vehicles and regulatory reference cycles, especially the excessive fuel consumption caused by the specific operating modes of internal combustion engines.
By implementing a series of steps in the electronic control unit of a spark-ignition internal combustion engine in a motor vehicle, including determining ignition advance and richness/leanness efficiency, calculating instantaneous fuel consumption losses, checking whether strategies affecting these factors are activated, recording and comparing consumption data from multiple strokes, the root cause of excessive fuel consumption can be identified.
It can accurately analyze the difference between actual fuel consumption and approved consumption, identify and explain the reasons for excessive fuel consumption, and provide detailed analytical evidence so that manufacturers can make corrections.
