The difference between tire 91V and 91H lies in their maximum speed ratings: the 91V has a maximum speed of 240 kilometers per hour, while the 91H has a maximum speed of 210 kilometers per hour. Below are some relevant details: 1. The number 91 is the load index, indicating the maximum load the tire can bear at different air pressures. For example, a 91V tire can support a load of 615 kg at 2.5 Bar. 2. Tires with 91V and 91H ratings should not be mixed. When purchasing tires, car owners should ensure that the tires are of the same specification, structure, manufacturer, and tread pattern as those originally equipped on the vehicle. Both the load index and the maximum speed under load must be consistent, especially for tires on the same axle. Otherwise, high-speed driving may affect the vehicle's handling stability and pose potential safety hazards.

What to Do If the Driver's License Is Lost?

Go to the local traffic police station or the online service hall to apply for a replacement. The process for replacing a lost driver's license is as follows: 1. There is no need to report the loss of the driver's license; you can directly apply for a replacement: Bring your ID card, residence permit or temporary residence permit (if in a temporary residence), and the photo collection receipt to the vehicle management office where the license was issued. Fill out a lost declaration, and then you can proceed with the replacement. 2. Cases where the new driver's license can be obtained on the same day: The photo collection receipt needs to be obtained from a specialized photo studio that can take ID photos. Just ask for a digital photo collection receipt for the driver's license. The vehicle management office can also take the photo, but the price is definitely higher than outside. It is recommended to take the photo in advance at an external photo studio.

Can 205 rims accommodate 225 tires?

From the perspective of vehicle safety, it is not advisable to replace the original 205 tires with 225 tires. It is recommended to maintain the same tire specifications as those originally equipped on the vehicle. If there is a need to change the tire specifications, it is essential to visit a professional modification shop for tire upgrades or consult the vehicle manufacturer. Size specifications: 205 refers to the tire width of 205mm, 60 indicates the aspect ratio of the tire's height to its width, meaning the height is 60% of the width. A smaller number indicates a flatter tire. R denotes the tire construction, indicating that the tire is of radial construction, meaning the cords are arranged radially within the tire body. 16 represents the rim diameter. Advantages of switching to 225: Due to the increased tire width, the vehicle's grip performance improves, driving stability is enhanced, braking performance is better, and safety is increased. Disadvantages of switching to 225: Increased tire width leads to higher fuel consumption, slightly reduced acceleration, and minimal change in noise levels.

What are the reasons for the engine warning light in the Envision?

The engine warning light may illuminate during a power-on self-test or under other circumstances. The power-on self-test is an indication that the vehicle is monitoring the status of all sensors before driving. Generally, if the engine is not started, the light will turn off on its own after about 3 seconds. In other cases, if the EPC indicator light remains on after the vehicle is started, the possible reasons include faults in the engine intake system, throttle valve, fuel system, engine itself, ECU control unit, or brake lights. Below is a detailed explanation of each potential issue: Sensor Problems: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may become damaged, have poor contact, or experience signal interruptions. When the ECU cannot accurately obtain engine data, the engine warning light will illuminate. Solution: Seek professional inspection and repair at a maintenance center promptly to eliminate safety hazards. Maintenance Issues: Poor engine maintenance is the most common cause of the engine warning light. Vehicles have specific maintenance cycles. Failing to adhere to these cycles, combined with poor driving habits, can increase the engine's operational burden, eventually triggering the warning light. Solution: Follow the maintenance schedule in the vehicle's manual for timely and comprehensive maintenance to rule out non-maintenance-related issues. Fuel Quality Issues: This refers to both fuel and engine oil. Vehicles require specific fuel grades and types of oil (semi-synthetic or full synthetic). If the wrong fuel or oil is used long-term, engine wear may occur, triggering the warning light. Solution: Use the recommended fuel grade and engine oil type for the vehicle. Poor Combustion of Air-Fuel Mixture: Faulty spark plugs, fuel pump issues, or clogged fuel lines can lead to poor combustion, causing carbon buildup or engine knocking. The oxygen sensor detects these issues and reports them to the ECU, which then illuminates the warning light. Intake Issues: Proper air intake is crucial for engine combustion. A dirty or clogged air filter can restrict airflow, leading to potential engine issues and triggering the warning light. Solution: Regularly clean or replace the air filter to ensure the intake system functions properly. Turbocharger Issues: Problems with the intake boost system or turbocharger can cause the engine warning light to illuminate. Common issues include turbocharger damage, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Solution: Visit a 4S shop for inspection and replacement of the turbocharger. Repairing such issues is often not cost-effective, so replacement is usually recommended. Exhaust Issues: Faults in the rear oxygen sensor, catalytic converter, or exhaust camshaft and bearings can trigger the warning light. The catalytic converter is particularly prone to damage from impacts or fuel system issues. Solution: Use lead- or silicon-based lubricants for maintenance and cleaning of the catalytic converter. Anti-Theft System: If the electronic anti-theft system malfunctions or the anti-theft controller is incompatible with the engine ECU, the engine may not operate correctly, and the warning light may illuminate. Solution: Seek professional diagnosis and repair at a specialized service center, as this issue cannot be fixed independently. Engine Misfire: One or more cylinders not functioning properly can lead to symptoms like reduced power, difficulty starting, or unstable idling. Solution: Identify and replace faulty cylinder components. If internal mechanical damage occurs, a major repair at a service center may be necessary.

Can I Wear a Necklace in My Driver's License Photo?

You can wear a necklace in your driver's license photo. Here are some relevant details about driver's licenses: 1. License Validity Period: If a driver has not accumulated 12 penalty points in any scoring cycle during the six-year validity period of their license, they can renew it for a ten-year validity period. If they continue to avoid accumulating 12 points in any scoring cycle during the ten-year validity period, they can then renew for a long-term valid driver's license. 2. Examination Content: The test includes three subjects: traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving). Prior to each subject test, an appointment must be made (special circumstances may allow for an appointment through the driving test green channel), and the test is taken after the appointment.

What does dm-i mean?

dm-i super hybrid is based on a high-capacity battery and high-power motor. During driving, the vehicle relies on the high-power motor for propulsion, while the gasoline engine's main function is to charge the battery. It directly drives the vehicle only when more power is needed, and even then, it works in coordination with the motor to reduce the load. Here is some relevant information: 1. Advantages of hybrid technology: This hybrid technology differs from traditional hybrid technologies that rely heavily on the engine, thereby more effectively reducing fuel consumption. 2. BYD's sedan models: BYD F3, BYD F0, Qin, Qin Pro, BYD E5, and BYD Surui. Taking the BYD F3 as an example, it is an A+ class passenger car produced by BYD. In terms of body dimensions, it measures 4533mm in length, 1705mm in width, and 1490mm in height, with a wheelbase of 2600mm.
