Can new National 5 vehicles still be registered now?

In regions where the National 6 standard has been implemented, the deadline for registering National 5 vehicles is the date when the local National 6 standard took effect; some areas may have extended policies allowing National 5 vehicles to be registered for a longer period, so new National 5 vehicles can still be licensed; in regions where the National 6 standard has not yet been implemented, National 5 vehicles can still be registered as usual. Below are the differences between National 5 and National 6: 1. Different carbon monoxide emission requirements: National 5 vehicles have a carbon monoxide content of 1000mg per kilometer; National 6 vehicles have a carbon monoxide content of 500mg per kilometer. 2. Different issuing departments: The National 5 standard was issued by the Ministry of Environmental Protection; the National 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine.

What are the body dimensions of the Jetta VS7?

The dimensions of the Jetta VS7 are 4600mm in length, 1841mm in width, 1661mm in height, and a wheelbase of 2730mm. Below is some related information about the Jetta VS7: Power performance: The Jetta VS7 has excellent power response. The combination of the 1.4TSI engine and 6AT transmission is considered a golden pairing. The initial acceleration is very linear, and if the throttle is pressed deeper, the transmission will immediately downshift by two gears, maintaining the engine speed above 3000rpm, making acceleration and overtaking effortless. Body dimension measurement methods: Measuring length is the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle. Measuring width is the distance between two planes parallel to the vehicle's longitudinal symmetry plane and respectively touching the fixed protruding parts on both sides of the vehicle. Measuring height is the distance between the vehicle's support plane and the horizontal plane touching the highest protruding part of the vehicle.

What does sg15w40 mean?

sg is the grade identifier of engine oil. 15w40 engine oil represents the grade of the oil, where 15 indicates the lowest temperature in winter that can be used is -20℃. The smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. Meanwhile, 40 represents the high-temperature viscosity in summer. The larger the number after W, the higher the applicable maximum temperature. Additional notes on adding engine oil: 1. Higher viscosity does not necessarily mean better engine protection: High-viscosity oil not only adversely affects the vehicle's fuel consumption but also fails to protect the engine effectively. Another function of engine oil is cooling and heat dissipation. When high-viscosity oil is blindly used, the engine's oil cooling performance will inevitably weaken. 2. Engine oils should not be mixed: The additive components in oils from different manufacturers are completely different. The chemical compositions of various additives can vary significantly, not only between different brands but also within different product lines of the same brand. Mixing oils from two brands can cause chemical reactions under the engine's high temperature, such as the formation of flocculent substances in the oil and increased viscosity.

Will Power Banks Explode If Left in a Car During Summer?

There is a possibility of explosion or spontaneous combustion under high temperatures. This is because power banks typically contain lithium batteries, which are highly prone to explosion when exposed to direct sunlight in a confined car environment where temperatures can exceed 80 degrees Celsius. Below is relevant information about power banks: 1. Introduction to Power Banks: A power bank is a device that can directly charge mobile devices and has its own energy storage unit. The main types available in the market are multifunctional power banks, most of which come with standard USB outputs. These can generally meet the charging needs of various common digital products such as mobile phones, MP3 players, MP4 players, PDAs, PSPs, Bluetooth headsets, and digital cameras. Essentially, a power bank is a convenient and portable high-capacity power source. It is a portable device that integrates energy storage, voltage boosting, and charging management. 2. Functions of Power Banks: The built-in charging plug of a power bank allows it to charge mobile devices directly via an AC power source while also serving as an energy storage device. It is a hybrid of a charger and a backup battery, simplifying the need for an additional charging plug compared to traditional backup power sources.

Is it necessary to install rear parking radar and reversing camera?

For drivers who are not yet proficient, these two systems are worth installing. Both reversing radar and reversing camera are driver assistance devices designed to aid drivers during reversing maneuvers. The radar alerts the driver to obstacles through audible signals, with some models also providing visual simulations on the display screen combined with sound alerts. The reversing camera visually informs the driver about road conditions. More details are as follows: 1. Radar Classification: Radars are generally categorized into front radar and rear radar. Rear radar enhances driver safety and consists of three components: ultrasonic sensors, a controller, and sensors. The rear parking radar assists drivers by providing audible or more intuitive visual warnings about surrounding obstacles when parking. Reversing cameras offer more intuitive and practical assistance than radars. 2. Principle of Reversing Camera: The reversing camera utilizes a rear-mounted camera to display real-time video footage of the rear view on the front display screen, giving the driver a clear and unobstructed view of the area behind the vehicle, making it more convenient and reliable to use. Nowadays, many vehicles come equipped with both reversing cameras and reversing radars for enhanced convenience and reliability.

What Causes High Low Pressure and Low High Pressure in Car Air Conditioning?

High low pressure and low high pressure in car air conditioning may be caused by a malfunction in the compressor or expansion valve. Under normal circumstances, the high-pressure side of a car air conditioning system should be around 1.5-2.0 MPa, while the low-pressure side should be around 0.15-0.35 MPa. If the pressure in the car air conditioning system is abnormal, it indicates a problem with the system, and it should be inspected and repaired at a service center. More relevant information is as follows: 1. Car Air Conditioning Structure: A car air conditioning system generally consists of components such as the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. 2. Car Compressor Range: Under normal conditions, when the compressor operates at 1500-2000 rpm, the high pressure should be around 1.5-2.0 MPa, and the low pressure should be around 0.15-0.35 MPa. If the ambient temperature around the vehicle is high, the high pressure may reach around 2.5-2.8 MPa, but it generally should not exceed 3.1 MPa.
