Advantages and disadvantages of double star tire
DoubleStar is a brand of double star tire. It is a domestic brand with a history of nearly a hundred years. Shandong tire industry is a state-owned main board listed company. Double Star attaches great importance to the quality problem of tires, and thinks that 1% quality problem may be 99% disaster for users, which urges Double Star to produce high-quality products, and second-class and defective products will be treated as waste products. In addition, the double star tire brand has been on the list for five consecutive years &; Ldquo Asia Top 5 Brands & rdquo。
Double-star tire has the advantages of wear resistance, safety, environmental protection and fuel saving. It is the first green beef tendon tire in the industry, and its design concept is wear-resisting, fuel-saving, environmental protection and safety. Green beef tendon tire has achieved the perfect combination of fuel saving, environmental protection and wear resistance by innovating tread formula and adopting environmentally friendly formula materials.
Moreover, the double-star tire adopts the new patent of steel cord compound tread, which makes the tire have superior puncture resistance and can prolong its service life, which is increased by 5% under the same conditions. In addition, the double-star tire has withstood the severe test of more than 36 million kilometers, showing its excellent performance index. The disadvantage of double-star tire is that its noise reduction ability is average.
however, DoubleStar double star tires also have quiet and comfortable tires, such as DH6. This tire is cost-effective and has a quiet and comfortable driving environment. It adopts asymmetric pattern design and special rubber and silicon formula, which can reduce the friction between molecules, thus reducing the rolling resistance of tires and achieving the effect of energy saving and fuel saving.
At the same time, the tire cord was optimized to make the tire more sensitive. This kind of tire is more suitable for driving on urban roads and is a good choice for family cars.
Reasons for frequent DPF regeneration
At present, all new diesel vehicles are basically equipped with DPF particle traps, and they need to live in the same place after working for a period of time. However, the owner who uses the residence function for the first time is not sure how long it will take for DPF to live in the same place. I think most of them can be finished in about 1-15 minutes.
how long does it take for DPF to live in situ?
it takes 1-15 minutes. The process of DPF in situ is as follows:
1. After the owner starts the engine, press the DPF in progress button in the central control, and the vehicle will automatically enter the in-process program;
2.& Ldquo will be displayed on the trip computer at this time. At the beginning of life &; Rdquo Then, the engine of the vehicle will speed up in place, and most of the speed will be maintained at 2 -25 rpm.
3. After the owner waits for 1-15 minutes, the speed drops. At this time, the trip computer will display &; Ldquo's complete life. , DPF fault light disappears immediately.
what is the reason why DPF appears frequently?
1. Use poor quality gasoline. Inferior gasoline contains a lot of impurities and carbides. At this time, vehicle exhaust may also contain more particulate matter, and DPF is naturally easy to be blocked.
2. Do not use low ash engine oil. Low-ash engine oil has less impurities, which is more suitable for China Sixth Car. If low ash engine oil is not used, the probability of DPF clogging will increase.
3. Long-term low-speed driving. Driving at a low speed will reduce the combustion efficiency of vehicle fuel, and the particles in the exhaust will increase at this time.
why not advocate dismantling particle traps?
I think the general reason is to prevent environmental pollution. If the particle trap is removed, the particles in automobile exhaust will be directly discharged into the atmosphere, polluting the air.
at the same time, the removal of the particle trap will affect the annual inspection. However, because the vehicle needs to check the exhaust gas quality during the annual inspection, if the particle filter is removed, the exhaust gas quality will definitely be lower than the national standard.
