German new energy vehicle brand Elektron is one of them, but the brand currently has no mass-produced models. Another is the British sports car manufacturer Elemental, which currently has only one model, the RP1, on sale. About Elektron: To ensure top-speed performance, Elektron Motors not only added numerous aerodynamic kits to the new car but also extensively used composite high-strength materials for the chassis. This helps to simultaneously reduce the additional weight brought by the batteries, further highlighting the advantages of lightweight and high rigidity. Additionally, with the push-rod suspension system standard in supercars, this vehicle offers excellent handling.

Can scratches on tire rims be repaired?

Scratches on tire rims can be repaired if there is no deformation or fracture of the rim. However, if the tire rim surface has cracks, deformation, or complete breakage, it cannot be repaired and the rim must be replaced. Continuing to use damaged rims poses safety hazards. The functions of tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support vehicle loads; 3. To reduce and absorb vibrations and impacts during driving. Methods for tire maintenance include: 1. Regularly clean stones from tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect front wheel alignment; 6. Adopt careful driving habits, choose road surfaces carefully while driving, avoid objects that can puncture or scratch tires, and steer clear of chemical spills that may corrode tires.

What does API engine oil represent?

API (American Petroleum Institute) standards are internationally recognized quality classification standards for lubricating oils, defined by two-letter grades that indicate the oil's quality level and suitable engine types. The first letter 'S' signifies its applicability to 'spark ignition' engines, i.e., gasoline engines. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is hailed as the 'blood' of automobiles. 2. Composition: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of base oil performance, imparting certain new characteristics, making them an essential part of lubricating oil.

Can Spark Plugs Still Be Used After 5 Years?

Spark plugs can still be used after 5 years. Generally, spark plugs can be stored for a long time if they remain unopened and unused. The shelf life of spark plugs during use varies depending on the type of spark plug and usage conditions. Main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Spark plug replacement intervals: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the user manual. The following standards can be used as a reference for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

What are the symptoms of a damaged release bearing?

The symptoms of a damaged release bearing are: 1. Normal noise in neutral gear, but a rustling sound when depressing the clutch; 2. A hissing or metallic friction-like sound when driving in gear, which does not affect normal operation. The release bearing is connected to the clutch pedal. When the clutch pedal is depressed, the release bearing presses against the diaphragm spring on the pressure plate, causing the diaphragm spring to lift. This action allows the clutch disc to disengage, potentially severing the connection between the engine and the transmission. Precautions for using the release bearing include: 1. Regular maintenance—during annual inspections or maintenance, use the boiling method to soak the bearing in grease for thorough lubrication; 2. Ensure the clutch release levers are properly leveled and the return spring's elasticity meets specifications; 3. Adjust the free travel to meet requirements, preventing it from being too large or too small; 4. Minimize the frequency of engagement and disengagement to reduce impact loads.
