What Causes the Car to Display an Engine Fault?

Car displaying an engine fault can be caused by the following reasons: 1. Poor quality gasoline that fails to meet standards, leading to incomplete combustion of the air-fuel mixture in the cylinders and excessive carbon deposits, which directly affects the normal concentration of the mixture, causing the engine fault light to illuminate accompanied by shaking; 2. Damaged oxygen sensor or sensor connector can result in the mixture being too lean or too rich, triggering the fault light; 3. Faulty air flow sensor or wiring prevents the engine computer from receiving the correct intake air signal, making it unable to control the fuel amount properly, thereby causing the mixture to be too lean or too rich, the engine to malfunction, and the fault light to stay on.

Is it a problem if the engine oil is slightly above the upper limit?

Adding engine oil beyond the upper limit can have several negative effects on the engine, including reduced power, increased fuel consumption, more carbon deposits, worsened exhaust emissions, and engine oil leaks. Below are the methods for adding engine oil and measuring it: 1. Method for adding engine oil: There is a yellow pull ring in the engine compartment, which is the engine oil dipstick. Pull it out, and at the very bottom of the dipstick, there are two marked lines (or sometimes two holes), representing the upper and lower limits of the engine oil. The engine oil level must always be maintained between these two marks—neither too much nor too little. 2. Do not measure the oil while the engine is running or immediately after stopping the engine, as this can lead to inaccuracies. Generally, you should wait at least 15 minutes after the vehicle has been turned off and is stationary, allowing the oil to fully return to the oil pan before checking. Additionally, ensure the car is parked on a level surface (if the car does not move when the handbrake is released and the gear is in neutral, the surface is level). 3. Measuring method: Pull out the oil dipstick, wipe it clean with a tissue, reinsert it, then pull it out again to check the oil level.

What is the fuel consumption of the Chenglong H5 Yuchai 240?

The fuel consumption of the Chenglong H5 Yuchai 240 is 16.9 liters per 100 kilometers. More information about fuel consumption is as follows: 1. Since most vehicles approach their economical speed at 90 km/h, the theoretical fuel consumption figures published by manufacturers are usually based on 100 km of driving at 90 km/h. (Displacement is determined by analyzing the carbon content in the exhaust gas using an exhaust analyzer and the carbon balance method). 2. The fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when driving a certain distance at a specified speed, serving as a theoretical indicator for the vehicle. 3. The fuel consumption per 100 kilometers is a value measured by manufacturers under controlled conditions using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated to determine the theoretical experimental fuel consumption data for the vehicle model.

What Causes a Car Battery to Suddenly Die in Winter

Here are the reasons why a car battery may suddenly die in winter: 1. Engine damage: This can occur due to loose or broken alternator belts, preventing the alternator from functioning. The alternator contains a rectifier - instantaneous high current can burn out its diodes. There are also carbon brushes and slip rings; excessive wear on the carbon brushes leads to poor contact. Additionally, stator coil issues like short circuits or open circuits will stop the alternator from working. Rotor coils may also experience open or short circuits, preventing power generation. Furthermore, broken charging circuits or loose connections can cause the car battery to discharge without recharging, resulting in a dead battery. 2. Insufficient electrolyte or leakage: During normal use, a car battery's electrolyte naturally evaporates and depletes. Therefore, regular maintenance should include checking electrolyte levels, which should remain between the maximum and minimum marks. Insufficient electrolyte naturally leads to inadequate battery charge. When low, only battery electrolyte or distilled water should be added - no other liquids should be used. However, most modern vehicles now use maintenance-free batteries where electrolyte loss is minimal; if levels are low, the entire battery must be replaced.

How to View Dash Cam Videos?

Methods to watch dash cam videos are as follows: 1. Dash cams with a display screen generally allow direct playback on the device. Press the MODE button to select and click on the recorded video file to play. Note that this method may not apply to all brands; please refer to the user manual for specific instructions. 2. Most dash cams now come with dedicated mobile apps that support video playback on smartphones, offering greater convenience. Simply download the corresponding app, connect to the dash cam's WiFi, and you can view playback in real time without consuming mobile data. 3. Dash cams save videos on TF cards. To watch playback, remove the TF card from the dash cam, insert it into a card reader, and then plug it into a computer to access and play the videos. 4. Some dash cams feature an additional USB port, allowing direct connection to a computer via a data cable. The computer will recognize the dash cam as a storage device, enabling you to click and view the videos.

What is the minimum vision requirement for obtaining a driver's license?

Vision requirements for the driver's license medical examination: For applicants of large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams, the naked or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For other types of driving licenses, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. Solutions for failing the vision test: Wearing glasses: You can retake the medical examination with properly prescribed glasses, as the driver's license medical examination allows corrected vision and does not require naked vision. Corrected vision: The vision requirement for the driver's license test in China is based on corrected vision, not naked vision. Therefore, when applying for a driver's license, it is advisable to promptly visit a professional ophthalmology hospital for a corrected vision examination. Retaking the medical examination at a hospital: If you fail the vision test at the driving school, you can also take the test at a hospital. Generally, the vehicle management office will designate several local hospitals for the examination. If you pass the examination, you can bring the medical examination form and relevant payment receipts back to the driving school.
