Under what circumstances is the S-block of a car used?

In the first case, you can use S gear in rainy and foggy weather.

Because in rainy and foggy weather or when there are a lot of water stains on the ground, and when the ground adhesion of some roads is poor, we can use S block, because it can make the car run at a low speed and enhance the power support of the car.

Let the car have enough horsepower to deal with the road with poor adhesion. But we must remember that when we are driving on this kind of road, if the vehicle slips, we must switch the gear to N gear to ensure our safety.

In the second case, use it when overtaking.

Because in the S gear, the power of the car is relatively large and the horsepower is sufficient, which meets the needs of friends who want to overtake quickly. However, it is necessary to transfer back to D gear after overtaking, because the expenditure on fuel consumption will be relatively large if S gear is used for a long time, so it will save fuel consumption to transfer back to D gear after overtaking.

In the third case, it is used when going up and down the slope.

When we go uphill, using S gear will give our car more power support, just like the manual gear of 1 gear going uphill, the car provides enough power to make it easier for our friends to go uphill; In addition, we choose to use S gear when going downhill, because S gear is a low gear. When we go downhill, we can effectively use the combination of engine braking and new braking system, so that our safety can be better guaranteed when we go downhill.

Extended data:

However, the disadvantage of using S gear is that it costs a lot of oil, so don't use it often. Of course, it doesn't matter if you don't care. However, from the point of view of protecting the car, S-gear will often cause certain damage to the car, because it always brings high-intensity load to the engine in a short time, and the rising temperature will aggravate the wear and tear on the car.

Removing carbon deposits: shifting the S gear can increase the load of the engine and raise the internal temperature in a short time, so it is very beneficial to remove carbon deposits in the engine.

Uphill: I believe many car owners will use D gear when climbing, but using S gear will make uphill more labor-saving and easier.
