What does dry dual-clutch mean?

Dry dual-clutch refers to a dual-clutch transmission where the clutch plates are not immersed in transmission oil. The dual-clutch transmission combines the flexibility of a manual transmission with the comfort of an automatic transmission, while also providing uninterrupted power output. Dual-clutch transmissions are divided into dry and wet types. They share the same structure and shifting principles, but differ in the cooling method of the clutch. The clutch plates in a dry dual-clutch rely on air cooling when engaged. Heat dissipation depends on airflow generated while the vehicle is moving, so there are some cooling holes around the clutch. During traffic jams, frequent starts, upshifts, and downshifts may cause the clutch plates to overheat due to insufficient cooling, triggering warnings and shortening the lifespan of the clutch plates. Wet dual-clutch transmissions rely on oil for cooling, with transmission oil added to the sealed clutch assembly, supplemented by a radiator. Wet dual-clutch transmissions must have a hydraulic pump, lubricant, cooling pipes, and an external cooling system. The advantage of wet dual-clutch is its superior cooling performance, allowing it to handle higher power and torque, making it more suitable for performance cars and high-power vehicles.

Is a residence permit required to get a driver's license in Suihua?

According to the 'One Certificate for All' policy, a residence permit is not required to obtain a driver's license in Suihua. Here is more information about the 'One Certificate for All' policy: 1. Introduction: The nationwide 'One Certificate for All' policy allows applicants to apply for a small car driver's license (C1, C2, C5) directly at any city in the country using their resident ID card, without the need to submit a residence permit or residence registration certificate. For Hong Kong, Macao, and Taiwan residents working or living in mainland China, they can use their residence permit for Hong Kong, Macao, and Taiwan residents to apply for a small car driver's license directly in any city nationwide without submitting accommodation registration certificates or other proof. 2. Convenience: All small car driver's license services can be handled nationwide with 'One Certificate for All.' Mainland residents can use their resident ID card to apply for a new driver's license, replace, renew, or validate their driver's license at any location nationwide without returning to their place of household registration or submitting various proofs such as residence or temporary residence permits. Hong Kong, Macao, and Taiwan residents can use their residence permit to apply for, replace, renew, or validate their driver's license directly in any mainland city without submitting other proof.

Should the Lynk & Co 03 use 92 or 95 octane gasoline?

Lynk & Co 03 should use 95 octane gasoline, as this fuel grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it indicated on the fuel tank cap of the Lynk & Co 03. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is higher, 98 octane gasoline is recommended. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline, as other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the wrong gasoline grade is occasionally used in the Lynk & Co 03, simply switch back to the correct grade after the tank is empty. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using a higher octane grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using a lower octane grade can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What Material Should Be Chosen for Spark Plugs?

Spark plug materials generally include nickel alloy spark plugs, platinum spark plugs, rhodium-platinum spark plugs, and gold spark plugs. Among these, platinum spark plugs and gold spark plugs perform well. The quality of spark plugs directly affects the vehicle's normal ignition and driving performance. Below is a relevant introduction to spark plug materials: 1. Nickel alloy spark plugs: These are the most common type of spark plugs and cannot be used in high-end vehicles; they are only suitable for low-end models. Their lifespan is approximately 20,000 kilometers. 2. Platinum spark plugs: The main characteristics of platinum spark plugs are their long lifespan, excellent durability, and stable spark performance, making them suitable for harsh conditions. Their lifespan is approximately 40,000 kilometers. 3. Rhodium-platinum spark plugs: These spark plugs use rhodium-platinum as the central electrode, which improves ignition performance and enhances the engine's ignition sensitivity. The lifespan of rhodium-platinum spark plugs is approximately 60,000 kilometers. 4. Gold spark plugs: Tantalum gold material has high hardness, high resistance, and a high melting point. Gold spark plugs offer the best performance. Gold is the most corrosion-resistant and precious metal, capable of meeting the demands of high-power engines and withstanding high-temperature environments, preventing the electrodes from melting or being damaged easily. However, their price is correspondingly high, ranging in the tens of dollars. Gold spark plugs can be replaced approximately every 6,000 to 8,000 kilometers.

What are the main items covered in the first maintenance of a new car?

New car first maintenance mainly involves changing the engine oil and oil filter. The first maintenance must be performed within 5,000 kilometers or six months of driving, whichever comes first. Car maintenance, also known as car servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle. It primarily includes maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, and extend the service life.

What is the purpose of heated rearview mirrors?

Heated rearview mirrors help keep the mirrors clear, allowing drivers to indirectly see the conditions in these areas, acting as a second pair of eyes and expanding the driver's field of vision. As the widest component installed on a vehicle, rearview mirrors are prone to impact in the event of a collision. To minimize scratches, rearview mirrors need to have a folding function. Rearview mirrors are tools that allow drivers to directly obtain external information about the rear, side, and lower parts of the car while seated in the driver's seat. For the convenience of drivers and to prevent traffic safety accidents and ensure personal safety, all countries require that vehicles must be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction.
