Do new hackers need a hot car to start in winter?

The correct way to warm up a car should be to go on the road from 30 seconds to 1 minute after starting, and keep driving at a low speed. The engine speed should not exceed 3,000 rpm, generally at 2,000 rpm, otherwise the severe wear and tear suffered by the engine and gearbox will be irreparable. After the engine temperature rises to the normal operating temperature (about 3 to 5 minutes), normal driving can be resumed.

The main reason for the car fever is that after the car is parked for a long time, the engine oil flows back to the oil pan at the lower part of the engine. Therefore, after ignition, the upper part of the engine is in a state of no oil and no lubrication. It takes about 30 seconds after starting, and the oil will be transported to the parts of the engine that need lubrication most, such as piston, connecting rod and crankshaft, due to the operation of the oil pump.

No driving in winter;

1, Don't open the window for ventilation Because of the cold weather, some drivers rarely open the window when driving in winter, even from the departure point to the destination. This is obviously not a good habit, because the carbon dioxide in the car will increase after a long time, and the driver will easily get sleepy. Inhaling stagnant air for a long time will also affect the health of people in the car and easily increase the chances of passengers suffering from respiratory diseases. ?

2, only use air conditioning internal circulation In terms of air conditioning, it is very common and common to use air conditioning when driving in winter. However, some drivers only use air-conditioning internal circulation when driving in winter, because the biggest advantage of air-conditioning internal circulation is to increase the temperature inside the car in a short time, which can make the car have a warm and comfortable environment.

The disadvantage of internal circulation of air conditioner is also quite obvious, because internal circulation refers to the frequent use of second-hand air in the car, which will greatly reduce the air quality and harm human health after a long time.

3, turning without slowing down, slamming the steering wheel to turn, a seemingly simple action actually hides a lot of things. When the road is slippery in winter, you should avoid sudden braking and sharp turning before turning. Never slam the steering wheel, it will easily make the wheels out of control.
