How Many Kilometers Can You Drive After the Fuel Tank is Empty?

Generally, you can drive 30-50 kilometers after the fuel gauge shows empty. The fuel pump is located inside the fuel tank and generates a significant amount of heat during operation. The fuel itself acts as its coolant, continuously cooling the pump to ensure proper functioning. Without the cooling effect of fuel, the lifespan of the fuel pump can be significantly shortened. Insufficient fuel can also damage the engine. Symptoms of a faulty fuel level sensor (fuel float) include: 1. The fuel gauge needle being stuck at a certain position; 2. The fuel gauge suddenly dropping to zero. The fuel float is a sensing device for fuel level, usually made of foam plastic, and together with the fuel gauge, it forms the vehicle's fuel level detection system. When the fuel level in the tank decreases, the fuel float sinks, moving the sliding arm and increasing resistance, which in turn reduces the current returning to the fuel gauge.

At an intersection, does the left yield to the right or the right yield to the left?

Traffic rules specify that the left should yield to the right. Relevant details: 1. Legal basis: According to Article 52 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when motor vehicles pass through an intersection without traffic signals or police direction, in addition to complying with the provisions of Article 51 (2) and (3), they must also adhere to the following rules: if there are traffic signs or markings, yield to the party with the right of way; if there are no traffic signs or markings, stop and observe before entering the intersection, yielding to vehicles coming from the right. 2. Additional information: In situations where vehicles from both the left and right sides are merging toward the center, the vehicle on the left must yield to the one on the right. This is a safety consideration, as a collision could impact the driver's side of the right-side vehicle. Therefore, the left-side vehicle must yield. Similarly, at an intersection without traffic lights, a vehicle going straight must yield to a vehicle coming from its right side. Failing to do so would result in full liability in the event of a collision.

Is the Particulate Filter Only Available in Volkswagen Vehicles?

Particulate filters are not exclusive to Volkswagen vehicles. A particulate filter is a ceramic filter installed in the diesel engine emission system, designed to capture particulate emissions before they enter the atmosphere. Functions of the Particulate Filter: The particulate filter can reduce soot produced by diesel engines by over 90%. The captured particulate emissions are subsequently burned off during vehicle operation. To determine if a vehicle is equipped with a particulate filter, you can use the following three methods: Check the and to see if they mention the particulate filter function. Additionally, carefully review the fault codes in the manual to check for a "Particulate Filter" warning light indicator. Inspect the label on the oil filler cap. If the cap clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter. Examine the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.

Why does the reversing camera work intermittently?

The intermittent malfunction of the reversing camera is usually caused by poor line contact. It is necessary to promptly check the wiring and the connection points of the vehicle installation to see if there is any loose connection. If so, it will naturally cause abnormal imaging of the reversing camera. In this case, simply ensuring a proper connection will suffice. It may also be due to aging of the video power cable, which can be resolved by replacing it with a new one. The reversing camera, also known as the parking assist system, or reversing visual system, or onboard monitoring system, is now widely used in various large, medium, and small vehicles for reversing or driving safety assistance. Its working principle is: a wide-angle infrared camera device is installed at the rear of the vehicle, allowing a clear view of the rear situation through the display screen inside the car.

What are the reasons for a scooter making a sizzling sound but failing to start?

The reason a scooter makes a sizzling sound but fails to start is due to issues in the ignition system or fuel supply system. When this happens, it is recommended to check both the ignition system and fuel supply system. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs, among others. Scooters generally feature a continuously variable transmission (CVT) with an automatic clutch, lacking gear design. Once started, you simply twist the throttle to move, and releasing the throttle will gradually slow down until stopping. Additionally, scooter wheels are smaller than those of other vehicles, and the transmission is mostly belt-driven.
