The EF on the car fuel gauge represents the current fuel level in the tank. E stands for empty, meaning when the gauge needle points to E, the fuel warning light on the dashboard will illuminate to remind the driver to refuel. F stands for full, indicating that the needle will point to F when the tank is completely filled with fuel. The working principle of the fuel gauge is similar to having a float in the fuel tank. The float sends different signals at different positions, and the dashboard displays the current fuel level based on these received signals. When the vehicle is on bumpy roads or going uphill/downhill, the fuel gauge needle may fluctuate and the fuel warning light may illuminate. This occurs because various movements during driving can cause changes in the float's height position. Therefore, it's recommended to check the fuel level when the car is on flat ground.

Is it permissible to drive a private car without wearing a mask?

It depends on the actual situation. When driving on open roads with only the driver present, wearing a mask is not required. However, when there are multiple passengers in the vehicle, all occupants, including the driver, must wear masks. Below is additional information: External and Internal Air Circulation Functions: Turn on the external air circulation to enhance ventilation. When passing slowly through densely populated areas, wear a mask, close the windows, and use the internal air circulation function. Transmission Routes: The primary transmission routes in vehicles are through contact, such as door handles, steering wheels, and car interiors—areas frequently touched for extended periods. When transporting a suspected COVID-19 patient in the car, virus-laden droplets can easily remain inside the vehicle. Moreover, driving through densely populated areas with poor ventilation and opening the windows simultaneously increases the risk of infection.

Is Replacing the Left Front Fender Considered an Accident Vehicle?

Repairing or replacing the anti-collision beam or rear fender does not classify a vehicle as an accident vehicle. Below is relevant information about accident vehicles: 1. Definition of an Accident Vehicle: An accident vehicle refers to a vehicle that has sustained damage from non-natural wear and tear incidents, leading to a decline in mechanical performance and economic value. Generally, an "accident vehicle" refers to one with structural damage. Additionally, water-damaged vehicles and fire-damaged vehicles also fall under the category of "special accident vehicles." 2. Methods for Identifying Accident Vehicles: Identification methods include exterior inspection, light inspection, checking insurance records, and examining the interior. 3. Conditions for Quick Accident Handling: Conditions for quick handling include no personal injuries, property damage not exceeding 2000 yuan, no dispute over accident liability among involved parties, the ability to drive the accident vehicle, all involved parties having vehicle insurance, and willingness to proceed to a designated location for damage assessment.

What type of suspension does the Dongfeng Fengguang 580 have?

Currently, the entire Dongfeng Fengguang 580 lineup is equipped with a front MacPherson strut independent suspension and a rear torsion beam non-independent suspension. When driving over some rough road surfaces, the suspension can filter out minor vibrations. However, when encountering higher speed bumps or sudden larger bumps, there might be a certain level of body sway due to the higher center of gravity. Below is some related information about the Dongfeng Fengguang 580: In terms of powertrain, there are two options. One is a 1.5-liter inline 4-cylinder turbocharged engine, paired with either a 6-speed manual or CVT continuously variable transmission, delivering a maximum power of 110KW, maximum horsepower of 150PS, and maximum torque of 220N·m. The other option is a 1.8-liter inline 4-cylinder naturally aspirated engine, matched with a 5-speed manual transmission, producing a maximum power of 102KW, maximum horsepower of 139PS, and maximum torque of 187N·m.

At which position of the right angle should the inner door handle align during a right-angle turn?

Look at the window decal above the inner door handle. Below is a relevant introduction about right-angle turns: 1. Overview: The right-angle turn is an assessment point in Subject 2 of the driver's license test. It evaluates the driver's ability to correctly operate the steering and accurately judge the vehicle's inner and outer wheel differentials when driving on sharply changing road sections. Engage first gear, release the handbrake, slowly lift the clutch to maintain semi-engagement for smooth forward movement. Keep the left wiper's round dot (the first rivet) on the car aligned with the yellow line at the right edge of the road, maintaining a 20 cm distance. Then, focus on a point slightly ahead of the middle door lock on the front left door of the car—remember this spot. 2. Deduction points: If the wheel touches the protruding point, it results in failure; each time the wheel touches the road edge line, 20 points are deducted; completing the maneuver by reversing deducts 10 points; failing to use the turn signal or using it incorrectly deducts 10 points.

Why is the fuel-injected motorcycle not accelerating?

The reasons why a fuel-injected motorcycle cannot accelerate include abnormal ignition, poor fuel flow, and engine issues. Here is some extended information: Break-in period: The break-in period of a motorcycle is crucial. The first 1,500 kilometers of a newly purchased motorcycle are particularly important. During this phase, it is recommended not to use the motorcycle at full load and to maintain a steady speed while riding, which can extend the motorcycle's service life. Warm-up: Pay attention to the warm-up process when using a motorcycle. It is advisable to warm up the motorcycle for about two minutes in summer before riding, and for more than three minutes in winter. This helps fully protect the various components of the motorcycle. Cleaning: While riding, pay attention to cleaning the motorcycle. Since many parts of the motorcycle are exposed to the outside, it is recommended to clean it at least twice a week. This reduces dust accumulation and improves the motorcycle's efficiency.
