Regardless of the temperature of the water tank, the working principle of the air intake grille is automatically adjusted according to the driving condition of the vehicle without human intervention.

When our car is used in winter, the fuel consumption may be higher, mainly because the fuel combustion efficiency of our car engine is not high at low temperature, and the engine condition is not good at low temperature, and the engine clearance is not in the best state, which will affect our power and fuel consumption.

For example, some of our high-end cars with higher prices have an electronic air intake grille on the water tank frame of the front bumper, which can better assist our engine cooling system. When we need to improve the efficiency of the engine and make it reach the normal temperature as soon as possible, our air intake grille is closed to prevent cold air from entering our engine compartment.

When the engine temperature rises to a normal state, it will open our air intake grille, remove air and help the engine dissipate heat.

So for this friend, blocking the air inlet of our car bumper can help the engine warm up.

But it will be more troublesome to block the air inlet of the bumper by ourselves, because when the temperature of our car rises, there will be no more air to dissipate heat through our water tank, and the temperature of our engine will also rise, so if we want to use the car for a long time, this method will be more troublesome, and we need to take off the baffle after the water temperature rises.
