Do cars need to be warmed up in cold weather

Cars need to be warmed up in cold weather, but they should be warmed up in the right way, not idling, which is very harmful.

The correct way to warm up a car:30 seconds to 1 minute after the motive power develops. However, don't run at high speeds at this time. The rpm should be kept low, and the ten million rpm should not be more than 3,000 to 3,500 rpm. Usually only 2,000 rpm is needed, otherwise the engine and transmission will be severely worn out. At this point, as soon as the engine temperature rises to normal temperature, you can resume normal driving again and get in the car and go wherever you want.

In fact, many people choose to heat up their cars right after they start them is not advisable. Some drivers are used to waiting for the water level to rise in the morning before starting it slowly. It is actually a fatal mistake compared to this situation as well.

For Yan ground heating the car, it is also easy to produce engine carbon deposits, which is a waste of gasoline. Nowadays, cars use EFI system, the engine can reach a stable speed in a short time.

The temperature of the outside world is also very small, so the traditional method of warming up the car in place really can not go, for the winter hot car is also more delicate. Time must not be too long, just like the old driver's photo is five minutes, not only waste of oil, but also easy to lead to increased carbon deposits.
