For highway driving, a tire pressure of 2.3 to 2.5 bar is appropriate. Tire pressure refers to the air pressure inside the tires, which plays a crucial role in a car's performance and power. The effects of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear on the central tread pattern of the tire, shortening its lifespan; 4. Increased body vibration, indirectly affecting the lifespan of other components; 5. Excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the car while driving; 6. Decreased puncture resistance, making it easier for sharp objects like nails or glass to penetrate the tire, leading to internal cracks, blowouts, and potential tire bursts.

How heavy is the Baojun 730?

The weight of the Baojun 730 is approximately 1.5 tons. Starting from the chassis, the 2019 Baojun 730 aims to enhance the overall driving and riding comfort. It adopts a five-link rear independent suspension, which is rarely seen in vehicles of the same class. Compared to the traditional torsion beam non-independent suspension, the independent suspension can better filter vibrations from bumpy and rough road conditions, effectively improving the comfort of passengers inside the car. Model Highlights: The biggest highlight of the Baojun 730 currently lies in the 1.5T+6DCT dual-clutch model launched at the end of last year, which addresses the shortcomings of the Baojun 730 series and better aligns with the positioning of a family MPV model. As an automatic transmission model, its price is relatively moderate. Appearance: The automatic transmission version of the Baojun 730 maintains the same appearance as the manual transmission version released earlier this year. The front face remains wide and simple, equipped with a shield-shaped active grille, LED headlight assembly, and front parking radar.

What Causes a Car's Odometer to Stop Working?

The reasons why a car's odometer stops working include sensor failure, loose plugs, and circuit breaks, all of which can cause the speedometer and odometer to stop functioning. Another possible issue is when only one of the two—either the speedometer or the odometer—works, indicating a fault in the internal circuit or mechanical parts of the instrument. In such cases, detailed inspection or replacement of the speedometer and odometer may be necessary. Below is an extended explanation: Composition of the Speedometer and Odometer: It actually consists of two meters—one for speed and the other for mileage. Traditional speedometers are mechanical, typically connected via a flexible shaft containing a steel cable. The other end of the flexible shaft is attached to a gear in the transmission. The rotation of the gear drives the steel cable, which in turn rotates a magnet inside the odometer's housing. The housing is connected to the needle, and a hairspring keeps the needle at zero when at rest.

How to Defog Your Car on Rainy Days?

Here are the methods to defog your car on rainy days: 1. For manual air conditioning, turn on the front window defogging mode, set the fan speed to maximum, switch on the A/C, and adjust the temperature to the lowest setting. The fog should clear in about a minute. 2. Some car models are equipped with rear window electric heating and side mirror electric heating functions. Simply press the switch, and the fog should clear in approximately one minute. 3. For automatic air conditioning, usually you just need to press the one-touch defrost button. Once pressed, the fan speed will automatically adjust to maximum, and the external air circulation will activate. 4. Use the heating system to defog. If the car has just been started, wait a few minutes for the engine to warm up and the water temperature to rise before turning on the heating. Set the fan speed to maximum and activate the front window defogging mode. The fog should clear in a few minutes. This method also works for fogging on the outside of the glass in summer.

Where to Apply for a Driver Information Card?

Driver information cards can be processed at banks designated by the local traffic bureau or immediately on the websites of relevant service providers. Drivers who wish to operate medium-sized or heavy-duty trucks must apply for a driver information card. Otherwise, if caught by transportation authorities, corresponding penalties will be imposed. According to relevant regulations, each driver can only apply for one card. It is not permitted for a single driver to hold multiple cards, as this could lead to misjudgment during traffic police inspections for dangerous driving, posing significant safety risks. For the first issuance of a driver information card, no processing fee is required, and there is no annual fee. However, if the card is lost or damaged and needs to be reissued or replaced, a processing fee must be paid, with the cost determined according to standards approved by the National Development and Reform Commission and the Ministry of Finance. After receiving the new card, vehicle owners should affix the driver information card to the upper middle part of the vehicle's windshield in a position that does not obstruct the driver's view. In cases where there is no windshield, the card should be affixed to an appropriate location on the front of the vehicle.

What Causes the Abnormal Noise When a Car Starts?

Abnormal noise occurs when a car starts but disappears as the speed increases. The possible causes include resonance noise and powertrain malfunction. Resonance Noise: Many parts of a car have the potential to resonate. When the car starts, the engine speed rises, resulting in higher vibrations. At this time, interior trim panels, seats, chassis, and other components may vibrate together. However, as the speed gradually increases, the engine speed stabilizes, and the vibrations decrease, causing the resonance between parts to stop, and the abnormal noise naturally disappears. In such cases, inspect each part one by one and then address the issue accordingly. Powertrain Malfunction: To quickly reach the operating temperature, the car automatically increases the idle speed. This is because most of the engine oil settles in the oil pan, and the oil's poor fluidity at low temperatures leads to inadequate engine lubrication, making it easier for abnormal noises to occur between parts. Once the engine warms up and lubrication returns to normal, this issue will resolve itself.

Can New Energy Vehicles Be Charged with Household Power?

Household electricity can be used to charge new energy vehicles. New energy vehicles can be charged with household 220V power, but it is essential to use a power strip rated at 4000 watts, with a maximum voltage of 220 volts or higher, and a maximum current of 16 amps or more—essentially a high-power strip designed for air conditioners. Charging an electric vehicle at home does not violate electricity regulations. However, since household power is typically 220V, it only allows for slow charging, often taking more than 8 hours to fully charge the battery. This makes it more suitable for overnight charging. Many electric vehicles now allow users to set charging times, which is particularly advantageous in regions with peak and off-peak electricity pricing. By setting the charging time, users can plug in the charger and let it automatically start charging during off-peak hours when electricity rates are cheaper. If you have a fixed parking space or garage, it is recommended to install a dedicated charging station for faster and more economical charging. Charging stations can utilize 380V power for fast charging, typically filling the battery in just over an hour. Additionally, household charging stations are not subject to tiered electricity pricing.
