AI Technical Summary
In existing technologies, the engine cooling system has a slow cylinder block warm-up rate during cold starts, which increases energy consumption during the warm-up phase, and the temperature control accuracy and thermal management efficiency of the cooling system are insufficient.
By using separate cooling cylinder block water jackets and cylinder head water jackets, and employing intermittent operation of electronic water pumps and dual thermostat control, precise control of the cooling system is achieved. This includes a small circulation mode where the cylinder block water jacket does not flow during low temperatures, a medium circulation mode where the cylinder block water jacket gradually participates in circulation during medium temperatures, and a large circulation mode for forced heat dissipation.
It accelerates the cylinder block temperature rise to the optimal operating temperature, reduces warm-up energy consumption, improves temperature control accuracy and thermal management efficiency, prevents engine overheating, and enhances the reliability and economy of the cooling system.
