Winter temperatures have plunged and roads have worsened due to snow and other weather, which has put the truck in a serious test. As the saying goes: "three points in the repair, seven points in the maintenance", if preparations for winter not ready, will lead to all kinds of fault, even affect safety, completes the maintenance work to ensure the normal operation of the truck in the cold winter. So what do truck drivers pay attention to in the winter?
Diesel, for cold region should switch to fit local low-freezing winter oil temperature, in order to ensure the diesel to normal combustion, diesel should have high cetane number and appropriate fractions, suitable for low temperature fluidity and viscosity, the evaporative and good oxidation stability.
tire
When winter comes, ordinary roads become hard and slippery, and water quickly turns to smooth ice. Such road conditions tend to cause tailgating and steering out of control. A few days of snow or even snow, the slippery ice on the road and the solid ice that rolled over it will test the performance of the tyres more.
The most important details of tire pressure
Due to the large temperature difference in the winter, the air in the tire has a larger thermal expansion and shrinkage, and the tire pressure is relatively easy to change. The tire pressure affects the performance and reflection of the tire directly, and affects the fuel consumption and service life. Excessive tire pressure will not only increase the risk of puncture, also can make the tyres in the form of a bulge in the middle of contact with the ground, causing the whole vehicle tyre grip range reduced obviously, when emergency braking can't provide enough friction to the brake the vehicle.
Too low tire pressure also makes the tyre side of the side of the contact surface, unable to become the whole tread contact the ground. In addition to increasing the wear of the tire, it can not provide enough ground floor area, which is no less dangerous than the high tire pressure driving. And the most frequently worn and worn part of the tire will cause the tire to be scrapped prematurely.
The inside of the tire wall should be carefully protected
It is well known that the tire wall is the most vulnerable part of the whole tire, and once the scratch or scratch occurs, it will basically lead to a flat tire. General tire maintenance more carefully check the tires when facing the outside of the car side, actually the inside of the tire wall of the test is not only less than the outside, the opposite will than the lateral side more damage. The sharp surface of the air pressure belt of the car at high speed may directly hit the medial tread and cause a scratch. Those bruises may be at any time dangerous in the cold of winter.
It is recommended that the vehicle be raised to check whether the inner wall of the tyre is injured after running the complex road and high speed. When you park your car in good visibility, you can directly see the inside of the tire.
