Different engine oils should not be mixed. Engine oil is used to maintain the operation of the engine, cooling and lubricating its components, and is also a crucial means to ensure the normal operation of various moving parts in the vehicle, reduce operational resistance, lower temperature, and minimize wear. Improper use of engine oil can not only shorten the engine's lifespan but may even lead to engine failure. The type of oil a car should use is related to the engine's compression ratio, and the oil grade should be chosen within the range of the engine's compression ratio. The gasoline grade has little to do with the quality of the gasoline itself; the gasoline grade represents its anti-knock properties, with a higher grade indicating better anti-knock performance. The anti-knock property is determined by the amount of octane added to the gasoline. The fuel grade refers to the octane number and is unrelated to the amount of impurities in the gasoline.

Does the Car Dashboard Need a Screen Protector?

Car dashboards do not need a screen protector. Screen protectors are meant to prevent scratches, but the dashboard is not prone to scratches under normal circumstances. The dashboard is a device that reflects the working conditions of various vehicle systems, and the indicator lights on it represent the following: 1. Engine fault warning light: Indicates an engine malfunction; 2. ABS fault warning light: Indicates a fault in the anti-lock braking system; 3. Tire pressure warning light: Indicates abnormal tire pressure; 4. Battery indicator light: Indicates the battery is drained or the generator has a fault; 5. Oil pressure warning light: Indicates low oil pressure; 6. Door warning light: Indicates a door is not properly closed; 7. Water temperature warning light: Indicates the engine coolant temperature is too high; 8. Antifreeze warning light: Indicates a lack of antifreeze; 9. Brake fluid warning light: Indicates low brake fluid level; 10. Power steering fluid warning light: Indicates low power steering fluid level; 11. Airbag fault warning light: Indicates an issue with the airbag system.

What are the emergency shutdown conditions for steam turbines?

The unit suddenly experiences severe vibration reaching the protection action value but the protection fails to activate, or there are obvious metal impact sounds inside the unit. The following is a related introduction to steam turbines: 1. Definition of steam turbines: A steam turbine is a type of turbomachinery (the term "turbine" comes from the transliteration of the English word "Turbine," meaning a rotary fluid dynamic machine) used to convert thermal energy of gas into mechanical work and vice versa. A steam turbine uses steam as the working medium and converts the thermal energy of steam into mechanical work. 2. Characteristics of steam turbines: As the most important thermal prime mover, steam turbines occupy an extremely important position in various fields of the national economy such as energy, electricity, and power engineering, as well as in national defense.

What is the replacement cycle for new energy vehicle batteries?

8 years is generally the replacement cycle for new energy vehicle batteries, with a specific mileage of 150,000 to 200,000 kilometers. If there is a power loss phenomenon, the battery may need to be replaced earlier. New energy vehicle batteries commonly use ternary lithium batteries, which have the advantages of sufficient power, less pollution, smaller size, higher energy density, good low-temperature resistance, and excellent cycle performance, making them more suitable for driving. However, the lifespan of a car battery mainly depends on the usage environment and methods. If the environment and methods are appropriate, the service life may be extended. When driving a new energy vehicle, try to maintain a constant speed as much as possible. When the battery capacity is less than one-third, it should be charged immediately to minimize battery damage. When using an electric vehicle in winter, try to charge it as you use it. After each use, charge the vehicle promptly while the battery temperature has not dropped to achieve better charging performance. Before charging, develop good habits of inspecting the appearance of the charging equipment and the vehicle's charging port to ensure charging safety. During winter charging, ensure that the environment is ventilated and dry.
