WEICHAI WP12 engine thermostat 610800060597 used for HOWO T7H HOWO TX TRUCK
FUNCTION
1. Main Temperature Regulation Function: Automatically switches between small and large circulation loops based on engine coolant temperature.
During cold starts/low temperatures, the thermostat is closed, the main valve is closed, and the coolant circulates only within the engine in a small loop, rapidly warming to its optimal operating temperature. When the coolant temperature reaches approximately 83°C, the wax-based temperature-sensing element expands, pushing the main valve open, allowing coolant to enter the large circulation loop and dissipate heat through the radiator, preventing engine overheating.
2. Maintaining Optimal Operating Temperature Function: The valve opens at 83°C, and fully opens at approximately 95-100°C, keeping the engine consistently within its optimal range of 85-95°C.
This improves combustion efficiency, power output, and fuel economy, reduces emissions such as nitrogen oxides, and also reduces cylinder/piston thermal stress, extending engine life.
3. Built-in Bypass/Secondary Valve Function: Assists in small circulation and pressure balancing, allowing a small amount of coolant to bypass when the main valve is closed, preventing localized overheating or pressure buildup. After the main valve opens, the auxiliary valve assists in regulating the flow rate, ensuring a smooth transition of the cooling system and avoiding drastic temperature fluctuations or "water hammer" phenomena.
4. Energy-saving and environmentally friendly auxiliary functions: Rapidly warms up the engine when cold, reducing idling fuel consumption and cold emissions. Works in conjunction with the water pump, radiator, and fan to improve the overall vehicle thermal efficiency.
