The evolution of trucks to keep out the cold! You may not know all this

● In winter, the temperature is low, it is very important to keep warm when driving

In winter, when the temperature is low, the truck often encounters a slow temperature rise when the vehicle is cold and starts, which will increase the fuel consumption. The reason is nothing more than the fact that the internal temperature of the engine is too low, and the viscosity of the engine oil is relatively high, which will lead to poor atomization of diesel.

Generally speaking, the vehicle itself has its own thermostat, and its most basic function is to keep out the cold. Because the thermostat itself is a valve that controls the flow path of the coolant, it is an automatic temperature adjustment device. It can automatically adjust the amount of water entering the radiator according to the temperature of the coolant, and adjust the heat dissipation capacity of the cooling system by changing the water circulation range, so as to ensure that the engine works within a suitable temperature range.

● Fan evolution The existence of electronically controlled silicone oil fan clutch does not require a warm cover

Compared with the traditional mechanical fan, the biggest feature of the electronically controlled silicon oil clutch is that the fan speed can be directly adjusted by electronic control. The actual performance is that the energy consumption of the vehicle is lower and the vehicle is more fuel-efficient. Mechanical fans rely on mechanical components to sense the temperature to control the speed of the fan, but its accuracy is poor, the heat dissipation efficiency is low, and it affects the energy consumption and power output of the engine. Therefore, electronic control has absolute advantages over mechanical control.

At present, most of the large-displacement commercial vehicles currently produced, such as the engines of more than 7 liters, 11 liters, and 13 liters in the national five and six stages, use electronically controlled silicon oil fan clutches.

● The air intake grille has evolved into an active type to replace the warm cover

Although the advancement of technology has made it unnecessary to add a thermal cover to our car, it is still extremely important to keep out the cold when driving in winter, because good thermal insulation measures can reduce fuel consumption to a certain extent.
