AI Technical Summary
Existing automatic transmission cooling systems in gasoline-powered vehicles cannot effectively raise the temperature in low-temperature environments, resulting in low transmission oil temperature, increased viscosity, decreased fluidity, and impaired lubrication performance and transmission efficiency, thus increasing fuel consumption.
By installing a second temperature control valve between the engine oil cooler and the transmission oil cooler, the transmission oil is heated by the engine heat, and active cooling is achieved by using a high-temperature radiator and cooling fan under high-temperature conditions, thus realizing rapid heating and temperature control of the transmission oil.
It enables rapid warming of transmission fluid in low-temperature environments, improves transmission efficiency, reduces fuel consumption, and protects transmission components under high-temperature conditions, preventing power interruption caused by overheating protection.
