One to the winter, not only people to maintain, the car should be protected. It's easy to have a problem with a careless car. Although the car technology has been more developed, the use of winter cars have a certain protective measures. But some things still need to pay attention to our own, in order to ensure the normal and safe use of the winter car. Old drivers will have hot habits, but there is a saying that now automotive technology has been developed, without heating. What is the truth how many, please listen to the Tao Xiangli motor vehicle parts.

Technology is the backing of the self willed

The reason lies in the winter hot connection, mechanical parts etc used before the car, the process did not meet the high standards of plastic and metal parts with very low temperatures, easy to break; with the previous car and is based on the single grade oil in different seasons, so it is necessary to preheat.

But now, with the technical innovation and production processes, steel and other parts of the quality has reached a very high standard, generally does not appear in the case of cold car breaking. Automotive technology after years of development, now the car is basically the EFI engine, and related technology is already very mature, finishing level, engine control precision and performance of the engine oil level have been greatly improved, which means the engine wear to a minimum, the engine is more and more durable and reliable.

On the other hand, now the oxygen sensor are equipped with heating wire, can be rapidly heated to 300 DEG C in three minutes, almost no dependence on hot car idle link, and now most of the vehicles are equipped with two oxygen sensor, the air-fuel ratio correction is more accurate.

If there is the habit of it, but also no ground for blame, to master the correct method is good:

1, manual transmission models: hang a don't step on the accelerator, the engine relies on low speed slow 3~5 minutes, then if it is a heavy car or from the underground garage ramp up, may feel some lack of power, can be a little more gas, etc. the water temperature table slightly upward, and then added to the second slowly, when the water temperature rises to the table pointer to nearly 60 degrees (more than 1/3 lattice water table), in order to gradually accelerate the upshift.

2, automatic shift: the oil viscosity in winter in the automatic gearbox will become large, the start should be maintained below 2000 turn running 3~5 minutes in the D file in general, automatic car in good condition without stepping on the accelerator, the low speed at idle speed is sufficient to enable the vehicle slowly walk forward. At this point, the automatic transmission will not rise, the gear box of the oil to the full cycle, oil viscosity gradually return to normal. Similarly, when the water temperature table pointer increased by nearly 60 degrees Celsius (water temperature of more than 1/3 grid), can be a normal acceleration.

In addition to the hot topic of winter maintenance a commonplace talk of an old scholar, but also pay attention to the following aspects:

First, the four seasons oil

And the summer is different, the car to the winter, the engine system for higher lubrication requirements, to avoid the cold weather on the engine damage, the choice of oil is particularly critical. The effectiveness of the oil is mainly determined by its viscosity, the ideal oil is best to run at full speed at full speed and high temperature to maintain consistency, do not break down, in the cold weather is easy to flow, not condensation.

The temperature is low in winter, the best to the car with low viscosity oil, because the oil is diluted, liquidity is better, and better able to protect the engine when the vehicle cold start. When the choice should try to choose a generic summer oil.

Two, the timely replacement of antifreeze

Anti freezing liquid mainly has two functions, and in the summer, the engine can be prevented from overheating, and the cooling system of the vehicle can be prevented from freezing in winter when the vehicle is stopped in the cold winter.

In the winter, especially in the north area in winter, the temperature is easily reduced to 0 DEG C or even minus 30 degrees, it put forward the demand for antifreeze antifreeze, so need to change with the ability of low temperature products, or if there is frozen will not be able to engine heat, serious will damage the tank and the engine.

Three, air conditioning need to clean up

After frequent summer and autumn after use, the air filter must be deposited a lot of dust, air conditioning and evaporation box keeps wet for a long time, a long time, these two places are very easy to breed bacteria and mildew, so before winter frequent use of warm air, there is a need for a clean-up of car air conditioning.

Four, tire

To a certain extent, the temperature determines the performance of the tire. In low temperature, tire cracks will become larger, the friction coefficient will become low, so winter driving must always pay attention to the tire wear, if there is abnormal wear of the situation, to timely adjust the tire pressure, and to the 4S shop or repair shop conditions for the four round of the four round to locate or change steering balance.

In addition to clear inclusions within the tread in time, try not to use make up more than once a tire, such as tires are hard cut, should immediately stop using.

Five in winter, with a glass of water to the wiper

Although the wiper is not divided into summer and winter, as long as the dirty windshield, have to spray cleaning. But in winter, because the water temperature will change from a liquid to a solid, this volume will be larger, it may be Donglie spray bottle.

In order to use the wiper, it must be replaced with a kettle of water jet wiper antifreeze performance and cleanliness
