Cold car starts frequently in winter. How to maintain the engine?
As soon as it was cold, the "battle of battle" about whether hot cars were needed in winter was restarted.
Two factions: hot car faction and non hot car faction
Hot car school
The car is not hot in winter, waiting to break down?
No hot car pie
Car making technology is increasing day by day. There is no need for hot cars at all.
So the question is, do you want a hot car in winter? How to warm up the car is the right skill to maintain the engine?
Will hot cars hurt cars?
In situ hot car will not damage the engine, but only by idling, it is difficult for the engine to reach the working temperature of No. 1, and it is easy to adhere to carbon deposition, resulting in emission pollution and fuel consumption.
Cold start in winter may lead to "scrapping" of the engine?
Many old drivers have the opportunity to remind novice drivers to warm up when the car starts cold in winter. If we don't warm up the car, the cylinder block in our car engine will be damaged, and the car engine will fail, which will cost a lot of money.
What is a broken cylinder?
The cylinder in the engine is equivalent to the combustion chamber. After the fuel is mixed and burned, it explodes and pushes the moving side of the cylinder to do mechanical work, so as to generate power. If the cylinder is broken, there will be scratches on the surface of the cylinder, so that the power of our vehicle can not be transmitted in time. Moreover, there are scratches on the surface of the cylinder block, which will also make the vehicle oil penetrate into the cylinder, and the well-known oil burning will occur!
Generally, the culprit of cylinder strain is the lack of lubricating grease in the cylinder. Due to the low temperature and high viscosity of lubricating grease in winter, the lubricity of lubricating grease in the cylinder will be greatly reduced. Therefore, it is necessary to start a hot car with a cold car in winter. When the vehicle is hot, the lubricating grease in the cylinder body will have a high degree of lubrication due to the increase of temperature, thus forming the role of protecting the cylinder body.
The right way to warm up?
After starting the vehicle, wait about 10 to 30 seconds. During the waiting time, you can adjust the sitting position of the lower seat, and then you can drive normally on the road.
Pay attention to driving at a low speed at the beginning of driving and avoid the operation of fierce refueling (generally, the engine speed does not exceed 2000 rpm). When the water temperature reaches 90 ℃, you can drive normally. Therefore, winter is not a "hot car", but a hot car while driving.
Special vehicle conditions
If the car is placed in a particularly cold place for a long time, the oil in all parts of the engine will return to the bottom of the engine after parking for a long time, and there will be a slight cylinder knocking sound when it is just started (the use of high-quality oil with good low-temperature fluidity and high oil film retention will avoid and reduce the occurrence of this kind of phenomenon). At this time, the car needs to be warmed up, not for too long, within 2 minutes.
In addition to mastering the skills of correctly "hot car" engine maintenance, routine testing of your car's oil, antifreeze, brake fluid and tires in winter is also required to ensure that your car is in good driving condition.
