What is the difference between Bosch imported spark plugs and domestic ones?

Bosch imported spark plugs and domestic ones differ in the following aspects: Difference in manufacturers: The original imported Bosch spark plugs are authentically produced in the original German factory, while the genuine ones are made by authorized domestic manufacturers under the guidance of German technicians. Difference in working voltage: The voltage standards differ between domestic and foreign countries, so imported Bosch spark plugs cannot be used without a transformer. Difference in machine performance: Genuine products are far inferior to imported Bosch in terms of performance. For example, the maximum thermal efficiency of genuine wall-hung boilers can reach 88%, while imported ones generally exceed 88%, with the highest reaching 95%.

What are the domestic hybrid car brands?

Domestic hybrid car brands include the Changan Jiexun Hybrid, Chery A5-BSG (which uses hybrid technology), and BYD F3DM (currently the most practical dual-mode hybrid product). Introduction to Hybrid Technology: Generally, hybrid refers to oil-electric hybrid, which combines fuel (gasoline, diesel) and electric energy. Hybrid vehicles are driven by an electric motor that assists the engine. Advantages of Hybrid Technology: Hybrid cars offer high fuel efficiency and superior driving performance. Since they use fuel for the engine and electric motor assistance during startup and acceleration, they consume less fuel. Simply put, compared to similarly sized conventional cars, hybrid vehicles have lower fuel costs.

What is the wear limit of an engine cylinder liner?

The wear limit of an engine cylinder liner is 0.50mm. Generally, if the wear exceeds 0.50mm, the cylinder liner needs to be replaced. Introduction to Cylinder Liners: A cylinder liner, short for cylinder sleeve, is embedded in the cylinder bore of the engine block and, together with the piston and cylinder head, forms the combustion chamber. Boring Standards: According to traditional engine repair specifications, piston rings come in standard sizes as well as oversized versions of 0.25mm, 0.50mm, 0.75mm, and 1.00mm, which serve as references for cylinder boring. In reality, cylinder liners wear unevenly, exhibiting eccentric ovality, scoring, and other conditions, making it impossible to bore the cylinder precisely to the wear value. Therefore, the actual measured wear value is typically increased by 0.25mm as the final boring standard (in some cases, even by 0.50mm, though considerations such as the hardness and strength of the cylinder liner surface prevent excessive enlargement).

Is it no longer necessary to display the annual inspection sticker for household vehicles?

Household vehicles no longer need to display the annual inspection sticker. To make things more convenient for the public, paper certificates will be reduced, eliminating the hassle of affixing (or removing) inspection stickers, making it easier to display and use them via mobile phones or other methods. Electronic Certificate: For application, when handling vehicle registration or issuing inspection certificates, the traffic management department of the public security authority will automatically generate and push the electronic inspection certificate through the information system. Vehicle owners can log in to the Internet-based traffic safety comprehensive service platform or the "Traffic Management 12123" mobile app to directly view and download the certificate. For Vehicles Exempt from Inspection Within 6 Years: For vehicles exempt from inspection within 6 years, the electronic inspection certificate can be directly applied for online. If the paper inspection certificate is lost or damaged, there is no need to apply for a replacement. It can be directly downloaded and used online. If a paper inspection certificate is needed, owners can choose to have it delivered by mail or pick it up at the vehicle management office.

Does a car with a production date over one year need an oil change when picked up?

A car with a production date over one year needs an oil change when picked up. The maintenance manual generally recommends changing the oil every six months or every 5,000 to 10,000 kilometers, whichever comes first. Therefore, even if the car has been sitting unused for a year, the oil should still be changed. Oil change intervals: Higher viscosity oils like 30-grade provide better engine protection and can be changed after 120,000 kilometers. However, if driving habits are poor, or if there is frequent highway driving or traffic congestion, it is advisable to change the oil earlier. Precautions for oil changes: When changing the oil, use the oil grade specified in the car's user manual and choose oil produced by reputable manufacturers. Using improper oil may lead to impurities clogging the cylinder block, affecting engine performance and reducing the car's power output.
