What is the typical memory card size for a dash cam?

Currently, the mainstream options are 8GB, 16GB, and 32GB. Most dash cams on the market support MicroSD cards up to 32GB. 1080P has become the standard resolution for dash cams. Taking an 8GB memory card as an example, it can store up to 180 minutes of 1080P video, which is barely sufficient. Therefore, memory cards below 8GB are no longer commonly used. However, dash cams, as high-speed read/write devices, have specific requirements for storage and read speeds. The Class rating is the current standard for measuring MicroSD card speeds, with classifications including Class0, Class2, Class4, Class6, and Class10. For instance, a Class2 memory card indicates a minimum write speed of 2MB/s, and higher numbers correspond to faster write speeds. It is recommended to use a memory card with at least Class6 speed for dash cams to ensure smooth video storage and prevent recording corruption. Additional information: 1. Imaging issues: At high speeds, the scenes captured by dash cams change rapidly, posing a significant challenge to the device's imaging and processing speed. To test this, we printed a mock license plate on A4 paper and had a person hold it by the roadside. A car equipped with a dash cam then passed by at different speeds to compare the impact of speed on the dash cam's recording quality. 2. Pixel issues: 1080P is a high-definition video format, and most mainstream dash cams support it. The term "megapixels" refers to the number of light-sensitive elements on the sensor. For 1080P resolution, 3-5 megapixels is ideal. For wide-angle lenses, avoid blindly pursuing extreme specifications, as larger angles can lead to more noticeable image distortion, which may render the footage unusable as evidence. When selecting a memory card, prioritize those with a write speed of Class6 or higher. Although dash cams record in loops, to maximize storage duration, it is advisable to use 16GB or 32GB memory cards.

What is the difference between China V and China VI emission standards?

The differences between China V and China VI emission standards are as follows: Different emission standards: China VI emission standards are more than 30% stricter than China V. Excluding the influence of working conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The China V standard was implemented nationwide on January 1, 2017. The China VI standard has been implemented since July 1, 2019. Different principles: During the China V stage, diesel vehicles and gasoline vehicles had different emission standards. However, China VI adopts a fuel-neutral principle, meaning that regardless of the fuel type, the emission limits are the same. Different issuing departments: The China V standard was issued by the Ministry of Environmental Protection. The China VI standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: China V is represented by "V," while China VI is represented by "VI." Different monitoring requirements for plug-in hybrid electric vehicles: Compared to China V, China VI has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China V standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China VI has two standards: China VIa and China VIb. The details are as follows: China VIa standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China VIb standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM (particulate matter) per kilometer driven. Affected by the China VI emission policy, although China V vehicles are not currently restricted from normal use, their resale value will be significantly impacted. For truck owners, if they purchase a truck on loan for cargo transport, the depreciation of the vehicle after repaying the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China VI vehicles, which have a longer service life and more road rights, are more advantageous.

What is the braking distance of the Geely Xingyue L?

Geely Xingyue L has a braking distance of 37.37 meters. Factors affecting braking distance: Braking distance is related to the braking force, the friction between brake pads and brake discs, tire grip, and road surface roughness. Ways to reduce braking distance: To shorten the braking distance, you can replace the tires with better grip, and choose to upgrade to better brake discs and brake pads. Introduction to the braking system: The braking system is a crucial component in a car, as it affects both driving stability and safety.

What is the optimal finger gap for coilover suspension front and rear?

The most suitable setting for coilover suspension is a two-finger gap both front and rear. Relevant information about coilover suspension is as follows: 1. Introduction one: Coilover suspensions are divided into standard coilover suspensions and full-length adjustable coilover suspensions, both adopting a monotube design. For standard coilover suspensions, the hardness of the shock absorber changes with height adjustment—the lower the vehicle height, the harder the suspension becomes, and vice versa. 2. Introduction two: Full-length adjustable coilover suspensions allow separate adjustments for hardness and height, meaning hardness does not change with vehicle height adjustment. Shock absorbers with a twin-tube design have a long suspension travel due to the low-pressure gas filled in the vacuum chamber, but their hardness remains largely unchanged as determined by the design.
