Why Can't the Dash Cam Turn On?

If the dash cam cannot turn on, you need to check whether the power supply interface is properly connected. If the power supply interface is connected correctly, you should verify whether the interface has power. Most dash cams rely on the cigarette lighter socket for power. If the cigarette lighter fuse is blown, the socket will have no power, causing the dash cam to stop working. A dash cam is a device that records images, sounds, and other relevant information during vehicle travel. It can capture the entire driving process in video and audio, providing evidence in case of traffic accidents. Car owners who enjoy road trips can also use it to document their adventures through challenging terrains.

The Difference in Usage Timing Between M Mode and S Mode

S mode represents the sport mode of a car, suitable for situations such as climbing hills or overtaking; M mode switches to manual mode, which is also applicable for hill climbing, but M mode is only available in vehicles with a semi-automatic transmission. By moving the gear lever to the right, the transmission will automatically switch to manual mode. Below are the relevant introductions: 1. Usage of S mode: When the car is in S mode, the engine operates at a high RPM. Under high RPM, the fuel injection volume increases significantly, leading to higher fuel consumption. Although the driving speed of the car will increase momentarily, prolonged use with delayed upshifting will impose a greater load on the car's transmission, thereby causing wear and tear. 2. Usage of M mode: During driving, M mode represents the semi-automatic transmission, where M stands for manual mode, including M+ and M-. Simply put, it allows for both automatic and manual gear shifting. M+ and M- are only equipped in models with semi-automatic transmission. If the gear lever is positioned between the M+ and M- symbols, pushing the lever towards M+ will increase a gear, whereas pushing it towards M- will decrease a gear. 3. Usage in overtaking situations: When overtaking, you can immediately switch to S/M mode, manually downshift to utilize the transmission's low gear with a large gear ratio, outputting high torque to rapidly increase the engine RPM. This enhances the car's acceleration performance, reduces the time needed for overtaking, and improves safety.

Where is the engine of the Geely Binyue produced?

Geely Binyue's engine is produced by Geely Auto itself. The engine adopts Volvo's technology, so it belongs to a domestically produced engine. The engine model specification of the Geely Binyue is JLH-3G15TD. The 1.4T engine has a maximum power of 104kW and a peak torque of 235Nm, while the 1.5T engine has a maximum power of 130kW and a peak torque of 255Nm. For daily maintenance of the Geely Binyue's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly according to usage conditions and keep the oil level moderate; When engine oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication parts, accelerating engine wear and increasing internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

What are the main items checked during a vehicle annual inspection?

Vehicle annual inspections mainly check the following items: 1. Inspect whether the engine, chassis, body and its auxiliary equipment are clean, complete and effective, whether the paint surface is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records; 2. Test whether the vehicle's braking performance, steering control, lights, exhaust emissions and other safety performance meet the technical requirements for safe operation of motor vehicles; 3. Check whether the vehicle has been modified, remodeled or altered, and whether the driving license, license plate and all registered vehicle records match the current vehicle condition, with any changes, and whether approval and modification procedures have been completed; 4. Examine whether the license plate, driving license and enlarged license plate characters sprayed on the vehicle are damaged, altered or illegible, and whether they need to be replaced.
