AI Technical Summary
Existing engine thermal management systems are difficult to adapt to changes in operating conditions when in a vehicle, resulting in a decrease in dynamic thermal efficiency and an inability to achieve optimal matching with the combustion system.
The dynamic thermal management method for automotive diesel engines is adopted. By collecting the actual operating parameters of engine speed and operating conditions in real time, and based on the steady-state calibration data of the engine test bench and the quantitative relationship analytical equation of the thermal management system, the Map control parameters of the electronic control accessories are optimized, the optimal fuel consumption rate is calculated, and precise control is achieved.
This improves the engine's dynamic thermal efficiency, reduces the computational power requirements for optimization, shortens computation time, and ensures optimal thermal management control under dynamic operating conditions.
