C3 driver's license cannot be directly upgraded to C1 driver's license. You need to apply for an additional driving license. The process for upgrading from C3 to C1 driver's license is as follows: The applicant should bring the required materials to a local motor vehicle driver training institution to register. The institution will then handle the procedure for adding the permitted driving category at the vehicle management office in its jurisdiction. After the applicant passes the tests for Subject 1, Subject 2, and Subject 3 in sequence, the vehicle management office will issue the motor vehicle driver's license within one working day. Passing standards for the tests: Traffic regulations and related knowledge (Subject 1) — Written test, full score is 100, 90 or above is passing. Field driving (Subject 2) — On-site, actual vehicle. The minimum requirement is 80 points, below 80 is failing. Road driving (Subject 3) — Highway or simulated site, actual vehicle. Full score is 100, must achieve 90 or above to pass.

Why does the Mazda Ruiyi suddenly make noise?

Mazda Ruiyi suddenly makes noise due to engine knocking. The following is a detailed explanation about the Mazda Ruiyi: 1. Background: The Ruiyi was developed with the concept of "Evolution of ZOOM-ZOOM" (ZOOM-ZOOM Evolution), aiming to be the "Best of CD Class (the strongest in its class)". It utilizes Mazda's independently developed new high-end product platform, which is one of the most advanced mid-to-high-end car platforms in the world to date. Based on this platform, the Ruiyi has undergone comprehensive evolution in terms of premium feel, driving convenience, power, safety, fuel economy, quietness, and many other aspects. It is an outstanding masterpiece of the Mazda brand, representing the ultimate pursuit direction of the Mazda brand. 2. Handling: In terms of handling, Mazda is widely recognized as a leader in the automotive industry. The first-generation Mazda6 was known as the "King of Corners" and was highly favored by domestic consumers. The Ruiyi inherits Mazda's ZOOM-ZOOM DNA in handling, offering even more driving pleasure than the first-generation Mazda6 and possessing handling comparable to top-tier sports models. The Ruiyi is equipped with an Electric Power Assist Steering (EPAS) system, which provides appropriate power steering at all times, truly achieving "unity between man and car, and spiritual connection".

Why Doesn't the New Energy Vehicle Move When Shifted to D Gear?

If a new energy vehicle does not move when shifted to D gear, it is likely due to a signal error in the transmission shift valve position sensor, which prevents the system from recognizing the current gear, or issues with the shift valve itself, such as incomplete gear engagement or blocked oil passages. Below are some daily maintenance tips for new energy vehicles: 1. Avoid high-current discharge: When starting, carrying passengers, or going uphill, avoid sudden acceleration to prevent instantaneous high-current discharge. High-current discharge can lead to the formation of lead sulfate crystals, damaging the physical performance of the battery plates. 2. Prevent overheating of charging plugs: Loose 220V power plugs or charger output plugs, as well as oxidation on contact surfaces, can cause plug overheating. Prolonged overheating may result in short circuits or poor contact, damaging the charger and battery, leading to unnecessary losses. If such issues are detected, promptly clean the oxidation or replace the connectors. 3. Avoid storing the battery in a depleted state: Never store the battery in a depleted state, which occurs when the battery is not recharged promptly after use. Storing a battery in a depleted state can lead to sulfation, where lead sulfate crystals form on the plates, blocking ion channels and causing insufficient charging and reduced battery capacity. The longer the battery remains idle in a depleted state, the more severe the damage. Therefore, when the battery is not in use, recharge it at least once a month to maintain its health.

What is the charging voltage and current for a car battery?

The charging voltage for a car battery should be between 14v and 15v, with the optimal charging current being 10% of its capacity. Here are some car battery maintenance tips: 1. Turn off all lights before shutting down the engine: Some older models do not support automatic power-off after the engine is turned off, so you need to manually turn off the headlights and interior reading lights before shutting down. If you need to find something in the car or require lighting, you can use a mobile phone or flashlight for illumination. 2. Avoid leaving the vehicle parked for extended periods: The battery installed in the car will self-discharge over time when left unused. Many car owners find it difficult to start the car or even discover a completely dead battery after returning from a business trip or vacation. Therefore, it is best to drive the car at least once a week, with a trip duration of at least 20 minutes, to allow the battery to charge while driving. 3. Close all windows before shutting down the engine: The switches for the car windows and sunroof are powered by the battery, so it is best to close all windows before turning off the engine, rather than after. Avoid using the long-press lock button method to close the windows after leaving the car.

What does cylinder compression ratio mean?

Cylinder compression ratio refers to the ratio of the total cylinder volume to the combustion chamber volume. Simply put, it is the ratio of the volume before compression to the volume of the compressed air-fuel mixture. Here are some methods to increase the compression ratio: 1. Change the connecting rod length: Lengthening the connecting rod raises both the bottom dead center and top dead center, reducing the combustion chamber volume and thereby increasing the compression ratio. 2. Modify the shape of the combustion chamber on the cylinder head. 3. Replace with a thinner head gasket or mill the cylinder block: This effectively increases the connecting rod length but may cause sealing issues. 4. Alter the shape of the piston crown.

What are the maintenance items?

Regular maintenance includes minor maintenance and major maintenance. The following are the specific introductions to maintenance: 1. 10,000-kilometer maintenance: Basic maintenance, commonly known as "minor maintenance," is required every 10,000 kilometers. The maintenance items include two: engine oil and oil filter. 2. 20,000-kilometer maintenance: 20,000-kilometer maintenance, commonly known as "major maintenance," requires replacing the oil filter and engine oil, as well as the cabin air filter and spark plugs. 3. 40,000-kilometer maintenance: The maintenance items for every 40,000 kilometers are more than those for 20,000 kilometers. In addition to engine oil, oil filter, cabin air filter, and spark plugs, the air filter and brake fluid also need to be replaced.

How Long to Soak a Three-Way Catalytic Converter in Oxalic Acid?

Soaking a three-way catalytic converter in oxalic acid for 30 minutes to 1 hour is sufficient, ensuring all areas are evenly immersed to avoid uneven cleaning. The three-way catalytic converter transforms harmful gases such as carbon monoxide and hydrocarbons emitted from vehicle exhaust into harmless substances through oxidation and reduction reactions. When high-temperature exhaust passes through the purification device, the catalyst in the three-way catalytic converter enhances the activity of harmful gases, promoting redox chemical reactions to purify the exhaust. Oxalic acid soaking can be used for rust removal from the three-way catalytic converter, but caution is required. Oxalic acid is highly corrosive to stainless steel, and high concentrations can also corrode the skin. Additionally, the resulting acid oxalate salts are highly soluble and somewhat toxic. If skin contact occurs, rinse immediately with water.
