Can the Dash Cam Record When the Car is Off?

Can the Dash Cam Record When the Car is Off? The dash cam can record when the car is off because it has a built-in battery. However, the battery capacity is limited and cannot support prolonged standalone use. Typically, dash cams are connected to the car's cigarette lighter for power. Another method to activate the dash cam is by connecting it to a power bank for charging. Below is relevant information about dash cams: 1. Definition: A dash cam is a device that records video and audio data during vehicle operation. Once installed, it can document the entire driving process, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also record adventurous journeys. While driving, it continuously records video, along with time, speed, and location data, functioning much like a "black box." It can also be used at home as a DV camera to capture life's moments or as a home surveillance device. 2. Functions: It safeguards drivers' legal rights. In cases of collisions with pedestrians, cyclists, or motorcyclists, drivers might face extortion attempts. A dash cam can provide crucial evidence. Playback of the recorded footage makes accident responsibility clear, enabling traffic police to handle incidents quickly and accurately. This allows for swift clearance of the scene to restore traffic flow while preserving vital evidence, contributing to a safer and smoother traffic environment.

Does a Bored Engine Have the Same Power as Before?

Bored engines do not have the same power as before; in most cases, vehicle power is reduced after boring. Reasons for reduced vehicle power after boring: The inner wall of the cylinder after boring is certainly not as smooth as the original factory finish. When the piston is compressed, the combustible mixture may leak, affecting cylinder pressure drop and vehicle power performance. After boring, the cylinder diameter increases, and larger pistons are required, which in turn increases the combustion chamber volume and reduces cylinder pressure. Main effects of a bored engine: After boring, the distance between the original cylinders becomes narrower, reducing the overall strength of the engine block. The inner wall of the cylinder is not as smooth as the original factory finish, leading to reduced piston sealing during compression, which affects vehicle power output. The cylinder diameter after boring is undoubtedly larger than the original, necessitating larger pistons. A larger cylinder diameter means the vehicle's displacement will increase, and fuel consumption will also rise. Reasons for not directly replacing the cylinder liner when boring an engine: The main reason is that the cylinder block of automotive engines is typically a cast iron block without a cylinder liner. When faced with internal cylinder roundness issues, boring is the only solution, as such cast iron blocks without cylinder liners cannot be fitted with them.

Is AX color change film domestically produced or imported?

AX car film is a domestic brand, specializing in high-end color customization with a 17-year history as a professional color formulation factory. It primarily provides multi-color label customization for several international top-tier footwear and apparel factories. Its flagship product, the AX "2000" series, utilizes imported release paper, modified cast polyurethane layers, and high-performance low-viscosity acrylic adhesive technology, ensuring optimal compatibility with paint surface properties. Below are the relevant details: Advantages of AX "2000": Taking the AX "2000" series as an example, its film thickness of 100μ-130μ enhances protection for the car's paint surface, reducing damage from stone chips, scratches, etc. Moreover, the AX-2000 series film is easy to remove, leaving almost no adhesive residue on the car body. The "2000" series boasts numerous advantages, including easy application, high flexibility, durability, chemical resistance, opacity, etc., making it an ideal choice for various car color changes and paint protection. Precautions for film application: Before applying the film, workers will use a spray system to reduce dust in the workspace, preventing hair and dust from affecting the film's adhesion. Then, the vehicle undergoes thorough cleaning, especially in crevices, using professional tools to remove dust. After cleaning, parts such as door handles, bumpers, and rearview lights are removed before the official film application. It is also recommended to choose genuine films from reputable brands and avoid cheap, low-quality films to prevent long-term issues.

How Many Kilometers Can 4 Liters of Oil Run?

4 liters of oil can generally run for about 50 kilometers. Mineral Oil: Mineral oil base is refined from crude oil. After extracting gases, gasoline, diesel, kerosene, and heavy oil from crude oil, the mineral oil base is then refined, leaving asphalt as the final residue. The mineral oil base is transparent with a slight amber tint, similar to the color of salad oil. Typically, mineral oil is very low-cost, but since the mineral oil base oxidizes more easily, even though modern mineral oils contain various imported additives, their service life is still about six months. Full Synthetic Oil: Full synthetic oil contains only PAO or ester-based synthetic compounds, all of which are artificially made through chemical processes. Initially used in the aviation industry, it was later adopted in racing and is now widely used in passenger cars. The advantages of full synthetic oil include high cleanliness, excellent fluidity, superior cooling capability, and outstanding oxidation resistance. Semi-Synthetic Oil: Semi-synthetic oil is a blend of synthetic oil with a portion of mineral oil, typically in a ratio of 4:6 (mineral oil to synthetic oil). It combines the benefits of full synthetic oil while being more affordable. However, semi-synthetic oil performs slightly worse than full synthetic oil in all aspects, with the main advantage being its lower price. Its replacement cycle is also slightly shorter than that of full synthetic oil.

How should the compulsory traffic insurance cost for vehicles be calculated?

The cost of compulsory traffic insurance can vary (except for the first year), and the calculation formula is as follows: Final premium = Base premium × (1 + floating rate linked to road traffic accidents) × (1 + floating rate A linked to traffic safety violations). According to regulations, the downward floating rate can only decrease by a maximum of 30%, meaning if the vehicle owner has driven safely for three consecutive years without any claims, the floating rate can decrease by 30%; conversely, the upward floating rate can increase by a maximum of 30%. Failure to pay compulsory traffic insurance may result in the traffic management department of the public security authority detaining the vehicle and imposing a fine of twice the amount of the unpaid premium. Compulsory traffic insurance is mandatory and must be paid. The role of compulsory traffic insurance: With the continuous increase in domestic vehicles, traffic accidents are frequent, but many responsible parties are unable to compensate for the victims' losses, causing irreparable hardships to the victims and their families. With the involvement of compulsory traffic insurance, when the responsible party is unable to compensate, the insurance company can help alleviate the difficulties caused by the traffic accident for the victims and their families. The liability limits are divided into death and disability compensation limits, medical expense compensation limits, property loss compensation limits, and compensation limits for the insured party who is not at fault in the road traffic accident.

What should vehicles do when navigating mountain curves?

When navigating curves on mountain roads, vehicles should adhere to the principles of 'reduce speed, sound the horn, and keep to the right.' Below is a detailed introduction to precautions when turning: 1. Mountain roads: When navigating curves on mountain roads, vehicles should follow 'reduce speed, sound the horn, and keep to the right.' 2. Left turns: For left turns, drivers should signal in advance and stay as close to the center of the road as possible to facilitate vehicles behind and those making right turns. Speed should be slower than during the day, and at intersections or curves, use high and low beams to alert oncoming vehicles while strictly adhering to traffic regulations by keeping to the right. Vehicles must reduce speed when turning.
