90% of people won't be hot car will you?

It was cold, and the hot car went out every day. Do not say that your car is very hot and you don't have to use a hot car. Then you go straight to the road after the car. Xiaobian clearly tells you that it is wrong. Driving directly after a car can cause great damage to the engine, so it is necessary to use a hot humid car before the cold weather. However, although the hot car is simple, more than 90% of people use the wrong method, so next we come to understand the little knowledge of hot cars.

Why hot car

If you want to heat the car in the right way, you need to know why it is hot. In fact, there are two main reasons for hot cars: First, the car is parked for a long time, the engine oil flows back into the oil pan, resulting in lack of lubrication of some parts of the engine; second, when the car is in a low-temperature environment The oil will become relatively viscous. At this time, the engine oil will become a strong resistance to engine startup. It will not only provide normal lubrication, but also increase engine wear and increase unnecessary fuel consumption.

99% use the wrong method

Most vehicle owners use idling hot wheels. However, according to statistics, more than 90% of engine parts wear is caused within three minutes after the cold start, because only the engine is moving, and the rest is not moving. Can not be converted, only wait for a long time after the road to improve engine operating conditions. Therefore, in the winter, especially in the cold winter, the idling hot car in the place can easily damage the engine. In the same way, it is not advisable to leave by car. This undoubtedly aggravates the wear of engine parts and may not cause serious problems in a short period of time. However, in the long term, the engine will be “life-extended”.

Do that 1% person

The correct hot car method should be to start the road 30 seconds to one minute after the start, but at this time, do not drive at high speed. Keep it at a low speed. The engine speed is limited to no more than 3,000 to 3,500 rpm. 2000 turns, otherwise the intense wear on the engine and gearbox can not be restored. After the temperature of the engine has risen to the normal operating temperature (it takes about 3 to 5 minutes), normal driving can be resumed.

Therefore, a moderate hot car is necessary, which can reduce the wear of the car engine and reduce emissions. But at the same time, we must remind everyone not to burn the endless hot car.
