Does a Car Dash Cam Require Data Usage?

A dash cam does not require data usage. Generally, dash cams do not have built-in memory and rely on memory card expansion or portable digital hard drives. For MicroSD or SD card expansion, capacities vary from 2GB, 4GB, 8GB, 16GB, to 32GB. For portable digital hard drives, capacities can range from 250GB, 500GB, to 1000GB. A dash cam is an instrument that records images, sounds, and related information during vehicle operation. After installation, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. Additional Information: Considerations When Purchasing a Dash Cam: 1. Stability: Since dash cams operate during driving and at the moment of an accident, stability is crucial. It is important to avoid issues like unstable footage or missing seconds due to quality problems. Battery life is also a critical feature for dash cams. 2. Camera Angle: The camera angle of the dash cam should not be overlooked. A too narrow angle may leave blind spots, affecting the comprehensiveness of the recording. Generally, a camera angle of 100 degrees or more is preferable. Currently, 140-degree and 160-degree angles are the most common on the market. 3. Night Performance: Many accidents occur at night, so the clarity of the dash cam's nighttime recording is essential. Many dash cams come with infrared functionality or features like anti-backlight and anti-glare. Be sure to inquire about these features when making a purchase.

Should Corolla use 92 or 95 octane gasoline?

Toyota Corolla is suitable for using 92 octane gasoline, and of course, you can also choose 95 octane gasoline, but under normal circumstances, there is not much necessity to use 95 octane gasoline. In addition to checking the suitable gasoline grade in the car manual, you can also check it on the fuel tank cap, which will also be marked. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should choose 92 octane gasoline, while cars with an engine compression ratio between 10.0-11.5 should choose 95 octane gasoline. However, with the use of some new technologies nowadays, the gasoline grade cannot be determined solely by the compression ratio. A high compression ratio can also be adjusted to use low-grade gasoline. This is because, in addition to the compression ratio, there are other influencing factors, such as the ignition advance angle, turbocharging technology, and Atkinson cycle technology. Generally speaking, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If Corolla occasionally uses the wrong gasoline grade, you only need to switch back to the correct gasoline grade after using it up. However, if the wrong gasoline grade is used for a long time, it will have the following effects: For vehicles recommended to use low-grade gasoline, using high-grade gasoline by mistake will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. That is, the engine's working capacity and thermal efficiency will both decrease, and the actual feedback experience is that the power becomes worse. For vehicles recommended to use high-grade gasoline, using low-grade gasoline will cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases and it will be ignited prematurely during the compression stroke. Once the gasoline combusts before the spark plug ignites during the compression stroke, resistance will occur during the upward stroke. This resistance will cause the engine to run very unstably. If it is only slight knocking, it will just increase noise and the damage to the engine is not obvious. If there is obvious knocking, it means the engine's working condition is already very severe. The vibration not only affects driving stability but also causes abnormal wear of the piston and cylinder, and in severe cases, it can even lead to cylinder scoring.

What is MEDALLION tire?

MEDALLION is a premium tire series under Maxxis, originating from Taiwan, and is a product of Cheng Shin Rubber Ind. Co., Ltd. Its main products include inner and outer tires for rickshaws, bicycles, motorcycles, ATV tires, agricultural and industrial vehicle tires, truck and bus inner and outer tires, as well as radial tires for cars, light trucks, and trailers. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high-low temperature effects during operation. Therefore, they must possess high load-bearing performance, traction performance, and cushioning performance, while also requiring high wear resistance and flex resistance, as well as relatively low rolling resistance and heat generation. They directly contact the road surface and, together with the vehicle suspension, mitigate the shocks encountered during driving, ensuring good ride comfort and smoothness, maintaining excellent adhesion between the wheels and the road, improving the vehicle's traction, braking, and off-road capability, and bearing the weight of the vehicle. Maxxis tire maintenance methods: Enhance awareness of tire safety and regularly inspect tires. Periodically correct wheel balance; unbalanced wheels can cause high-frequency oscillations during high-speed driving, leading to uneven tire wear. Regularly rotate tires; to ensure even wear across all tires on the same vehicle, perform tire rotation every 5,000 kilometers. In daily use of Maxxis tires, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves gradually become shallower. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks may seem minor but can be a hidden danger for tire blowouts at high speeds. Additionally, immediately remove pebbles from the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials related to rubber deterioration. After parking, the driver should not turn the steering wheel, as this accelerates tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and tire pressure increases. In such cases, stop to let the tires cool down naturally. Never release air to reduce pressure or splash water to cool down, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and sudden stops to prevent accelerated tread wear caused by dragging between the tires and the ground.

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.
