What does the term 'on-demand four-wheel drive' mean for four-wheel drive vehicles?

On-demand four-wheel drive in four-wheel drive vehicles refers to the system that activates four-wheel drive when necessary, while operating as a two-wheel drive system under normal conditions. Compared to other four-wheel drive systems, on-demand four-wheel drive has a simpler structure, effectively reducing costs and overall vehicle weight. In daily use, on-demand four-wheel drive can handle sudden slipping effects, improving driving performance. However, it's important not to expect on-demand four-wheel drive to handle intense off-road conditions, as it is far less capable than professional four-wheel drive systems. Having four-wheel drive allows vehicles to tackle more complex road conditions, but it's not simply about all four wheels turning together. It also involves power distribution issues. Different road conditions require different power allocations to the four wheels, which can be divided into front and rear wheel sections. The task of power distribution is handled by the differential.

What is the function of run-flat tires?

Function of run-flat tires: After a tire blowout accident occurs, it allows the vehicle to continue driving at a speed not exceeding 80 kilometers per hour for up to 80 kilometers. The technical name for run-flat tires is "puncture-resistant tires," marked with RSC. Generally, the sidewall of run-flat tires will have the RSC mark. The run-flat feature of these tires lies in their thicker sidewalls. Even when an RSC tire suddenly loses pressure, it can still support the vehicle's movement due to its thicker sidewall, preventing the steering wheel from losing control due to a blowout. A blowout is undoubtedly a fatal blow to a high-speed vehicle. If the speed exceeds 120 km/h, the survival probability of the occupants is extremely low. Therefore, safe driving is the prerequisite for road safety.

Can Coaxial Speakers Be Installed in Car Front Doors?

Coaxial speakers can indeed be installed in car front doors. Speakers, commonly referred to as car audio drivers, are typically categorized into coaxial speakers, component speakers, and subwoofers. A coaxial speaker integrates both tweeter (high-frequency) and woofer (mid-low frequency) drivers into a single unit, effectively combining two speakers in one. Specifically, it mounts two transducers concentrically on the same axis to handle different frequency ranges. The standout feature of coaxial speakers lies in their exceptional phase fidelity across the full audio spectrum (highs, mids, and lows). This enhanced phase accuracy delivers precise sound localization and vivid imaging, ensuring distinct positioning of instruments in complex musical passages without muddiness. Consequently, music reproduction remains clear and detailed. Such speakers excel in reproducing AC3-standard home theater audio from DVDs and HiFi playback, making them particularly suitable for confined spaces like vehicle interiors.

How to Determine if the Battery is Fully Charged?

Methods to identify a fully charged battery are as follows: 1. Judging by charging time: For a typical household car, the battery capacity is usually 60Ah, and the required charging current is one-tenth of the battery capacity, which is 6A. Charging at this current usually takes about 5 hours to fully charge the battery. If using a lower current, it may take around 10 hours to fully charge. 2. Judging by battery current: Use a multimeter to measure the current. When the displayed current value is about 2% of the battery capacity and remains stable, it indicates the battery is fully charged. 3. Judging by battery voltage: A 12V battery's actual voltage is slightly higher, typically around 13V when unloaded and no less than 11V under load. When the battery voltage reaches 13V as measured by a multimeter, it indicates the battery is fully charged. 4. Judging by observing the electrolyte state: When bubbles appear in the battery's electrolyte, it indicates the battery is fully charged. If direct observation is not possible, you can also listen for sounds to determine.

How to Check the Tire Pressure Monitoring on Volkswagen Tharu?

Volkswagen Tharu will only automatically display tire pressure information on the dashboard when there is an abnormality in the tires, as it is equipped with a passive tire pressure monitoring system. The dashboard does not show specific numerical values, only indicating which tire has a problem. Volkswagen Tharu tire pressure light reset tutorial: 1. Before resetting, ensure the tire pressure is restored to normal levels; 2. Start the vehicle; 3. Press and hold the SET button for the tire pressure reset until the tire pressure light on the dashboard disappears. Volkswagen Tharu tire replacement tutorial: 1. Ensure the car is parked on a level and solid surface, then loosen all the tire nuts. The nuts should be removed in a diagonal sequence to avoid damaging the wheel hub; 2. Place the jack directly under the support point and slowly raise the chassis until it reaches a safe height for tire removal; 3. Install the new tire, manually tighten the nuts, then lower the vehicle. When using tools to tighten the nuts, follow the same diagonal tightening sequence, and fully tighten the nuts once the tire touches the ground.

What is the meaning of Ackermann angle?

Ackermann angle refers to the angle formed between the two steering wheels when the vehicle is turning. The following is a detailed introduction about Ackermann angle: 1. Overview: Ackermann angle refers to the angle formed between the two steering wheels when the vehicle is turning. Ackermann refers to the geometric characteristics of the steering system shape, which causes the inner wheel to turn more than the outer wheel when the vehicle is turning. The inner wheel usually turns at a larger angle than the outer wheel. When the steering angle is increased, this angle will also increase accordingly. 2. General situation: Usually, the Ackermann angle is set by changing the fixed hole position of the steering push rod on the steering cup. When the angle of the steering push rod is larger, it will produce more Ackermann angle, and vice versa. Since the turning radius of the inner and outer wheels is different when the vehicle turns, Ackermann can help the two front wheels point in the correct driving direction respectively to obtain more grip.
