AI Technical Summary
Technical Problem
Existing engine control systems fail to accurately adjust the fuel mixture during transient operating phases due to poor airflow estimation, leading to increased pollutant emissions, engine noise, and driving discomfort due to jerking.
Method used
Implement a predictive control method for the fuel mixture in engines with variable intake valve timing, using a response model to anticipate the valve position and adjust fuel injection accordingly, reducing the dead time in airflow estimation.
Benefits of technology
Improves the accuracy of fuel injection during transient phases, reducing pollutant emissions and engine noise, and enhancing driving comfort by aligning fuel delivery with actual airflow conditions.
