What does rec mean on a dash cam?

Dash cam rec is the abbreviation of the English word Recording, meaning it is in the process of recording. Nowadays, dash cams have become an essential safety device for car owners. The functions of a dash cam are as follows: 1. Protecting the legal rights of drivers: In case of a collision with pedestrians crossing the road or cyclists and motorcyclists, drivers might face extortion. A dash cam can provide valid evidence to protect the driver. 2. Quick and accurate accident handling: By reviewing the recorded footage, the responsibility for the accident becomes clear, allowing traffic police to handle the incident swiftly and accurately. This not only enables quick clearance of the scene to restore traffic flow but also preserves crucial evidence from the incident, contributing to a safer and smoother traffic environment. 3. Reduction in accident rates: If every vehicle is equipped with a dash cam, drivers are less likely to violate traffic rules recklessly, leading to a significant decrease in accident rates. Moreover, any vehicle involved in an accident can be captured by other vehicles' dash cams, greatly reducing hit-and-run cases.

Are New Energy Vehicles Afraid of Being Flooded?

All vehicles are afraid of being flooded because they contain electrical circuits, which can develop faults after being submerged in water. Therefore, it is not recommended to drive in deep water areas. Below is more information about new energy vehicles: 1. Introduction: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. 2. Classification: New energy vehicles include four main types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices).

Can new energy vehicles be registered as commercial vehicles?

Local policies vary, and whether a vehicle can be registered as a commercial vehicle requires consultation with the local vehicle management office. All vehicles participating in commercial operations must meet the following main technical conditions: 1. The vehicle must be clean and fully equipped: exposed bolts and nuts must be securely fastened, and the vehicle's power performance must be good. 2. The engine must operate well: fuel and lubricant consumption should be normal, with no knocking noises when the coolant temperature is above 50°C, and no leakage of oil, water, gas, or electricity. 3. The chassis assemblies must be securely connected: no overheating or abnormal noises, with good performance and no lack of lubrication; leaf springs must not be broken or misaligned; tire pressure must be normal; connection and protective devices for vehicles and trailers must be complete and reliable. 4. Steering must be light and flexible: tie rods and ball studs must not be loose, with good performance, front wheel alignment must meet requirements, foot brake efficiency must comply with regulations, hand brakes must be reliable, and trailer brake devices must be effective.

What is taught on the first day of Subject 2?

On the first day of Subject 2, the main learning content is familiarizing with the gear positions. Below is more information about Subject 2: 1. Content: Subject 2 includes five items: reversing into a parking space, stopping and starting on a slope, turning at a right angle, parallel parking, and driving through curves. 2. Passing standard: For large vehicles, a score of 90 is required to pass, while for other vehicle types, a score of 80 is sufficient. Additional information: 1. Subject 1: The full score for Subject 1 is 100, and a score of 90 is required to pass. 2. Subject 3: The full score for Subject 2 is 100. For large buses, trailers, city buses, medium-sized buses, and large trucks, a score of 90 is required to pass, while for other vehicle types, a score of 80 is sufficient.

How Often Should the Transmission Fluid of the Sylphy be Changed?

Sylphy's transmission fluid should be changed every two years or every 40,000 kilometers. Transmission fluid is an oil product that keeps the gear system clean, providing lubrication to extend the lifespan of the transmission device. It also offers highly effective lubrication at low temperatures and reduces oil loss under harsh operating conditions. The Sylphy is a compact car under Nissan, with body dimensions of 4631mm in length, 1760mm in width, and 1503mm in height, and a wheelbase of 2700mm. The 2019 National VI version of the Sylphy is equipped with a 1.6-liter inline 4-cylinder naturally aspirated engine.

Is It Normal for New Car Tires to Have No Rubber Hairs?

Normal. Rubber hairs are small rubber burrs on tires, known as "little braids" in the industry, caused by vent holes in the tire vulcanization mold. Nowadays, technologically advanced tire manufacturers have already resolved this issue. More details about tire rubber hairs: 1. Rubber hairs do not increase tire noise: Tire noise mainly occurs when the vehicle is driving at high speeds, and the tire rotates rapidly, compressing and releasing the air within the tire treads. This continuous "compression-release" process generates noise. The faster the speed and the heavier the vehicle, the greater the noise. Under such high-speed rotation, the effect of rubber hairs is negligible. 2. Rubber hairs do not enhance grip: This is only theoretical. If the tire surface has rubber hairs, it may make the surface rougher, theoretically increasing friction. However, the tiny rubber hairs contribute insignificantly to the tire's overall friction. 3. Relationship between rubber hair length and tire quality: The length of rubber hairs depends on the equipment and manufacturing process used to make the tire. The length of rubber hairs cannot be used to judge the quality of a tire, and rubber hair lengths vary among different tire specifications and models.
