How to Drive a Dongfeng Honda Automatic Transmission Car?

Is Wanliyang CVT25 a steel belt or a chain?

Wanliyang CVT25 uses a steel belt. Here are the specific details about Wanliyang CVT25: 1. The Wanliyang CVT25 transmission is currently one of the best domestically produced transmissions in China. 2. The maximum torque capacity of this transmission is 250Nm. 3. The CVT25 is equipped with an efficient vane pump with a flow controller, which improves operational efficiency by about 30% compared to traditional gerotor pumps. It also features an additional torque converter compared to the CVT19, ensuring better reliability in terms of quality. The steel belt is sourced from Bosch, ensuring high quality. 4. One major issue with this transmission is that it produces significant noise.

What Causes the Abnormal Noise from the Car Belt?

The abnormal noise from the car belt can be attributed to the following three reasons: 1. Aging of the Drive Belt: The drive belt is primarily made of rubber, which hardens and becomes brittle over prolonged use. This reduces the friction coefficient, affecting power transmission and leading to slippage. After prolonged slippage, the rubber softens due to friction-generated heat. 2. Insufficient Belt Tension: When the belt tension is insufficient, the belt is prone to slippage, similar to aging. Belts are automatically adjusted for tightness via a large spring mechanism that presses on the belt. If the belt is too loose, friction decreases, causing abnormal noise due to slippage. 3. Severe Belt Wear: When the car belt is severely worn, the contact area between the belt and the pulley significantly decreases. Even slight pressure can cause the belt to sink deeply into the pulley groove, making rotation strenuous and resulting in abnormal noise.

Can a New Car Be Waxed?

New cars can indeed be waxed, but it is generally not recommended to wax a car immediately after purchase. Car wax serves multiple purposes, including waterproofing, resistance to high temperatures, anti-static properties, UV protection, and enhancing the gloss of the paint. Waxing is a traditional aspect of car care that helps protect the paint. However, new cars come with a factory-applied protective wax, so they typically do not require waxing for the first six months. The frequency of waxing depends on how long the wax layer remains effective on the paint surface, which in turn depends on the quality of the wax used. Various waxes available on the market, regardless of their price range, do not come with a specific duration of effectiveness. It is advisable to reapply wax once the existing wax layer wears off.

How long does it take to renew a driver's license on 12123?

The replacement of a driver's license through the Traffic Management 12123 platform generally takes up to 15 days to receive. There are two key points regarding the handling of an expired driver's license: 1. Annual review expiration: If the annual review is overdue, it means the vehicle has not undergone the required annual or biennial inspection. For holders of driver's licenses with permitted vehicle types "C", "E", or "F", the review will be conducted together when renewing the license upon its expiration. Drivers holding new version driver's licenses with permitted vehicle types A1, A2, A3, B1, B2, N, or P must undergo an annual physical examination; 2. Expiration of the main driving license: Vehicles without a valid driving license are not permitted to drive on public roads.

How to Increase Power in Naturally Aspirated Engines?

Methods to enhance power in naturally aspirated engines are as follows: 1. Use a high-flow air filter to smooth the intake tract. 2. Modify with a direct throttle body. 3. Improve the efficiency of the intake and exhaust systems, such as altering the cam profile or even using an electro-hydraulic camless valvetrain to extend valve lift and duration. 4. Adjust the parameters of the electronic control system to boost power. 5. Use high-energy, stable spark plugs, high-quality gasoline, and reduce vehicle weight to gain some power. 6. Lower the intake air temperature. The principle behind lowering intake air temperature is that colder air is denser, allowing more mass of air to be drawn into the engine cylinders for mixing with fuel, leading to more complete combustion and thus greater energy output.

Is It Dangerous to Leave Windshield Washer Fluid in the Trunk Under the Sun?

There is no danger in storing windshield washer fluid in the trunk of a car. Windshield washer fluid has the following four characteristics: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives, which typically have functions such as wetting, penetrating, and solubilizing, thereby effectively removing dirt; 2. Anti-fog performance: It forms a single-molecule protective layer on the glass surface, preventing the formation of fog droplets and ensuring clear visibility; 3. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface can eliminate static charges, providing anti-static benefits; 4. Anti-corrosion performance: The fluid contains multiple corrosion inhibitors, ensuring no corrosion to various metals, and it is safe for car paint and rubber components.
