What kind of fuel is used for China VI vehicles?

China VI vehicles use standard gasoline and diesel, which have superior fuel quality and emission data compared to China V standards, reducing more particulate matter and lowering emissions of non-methane organic gases and nitrogen oxides. Overall, compared to "China V," the emission limits for "China VI" are tightened by approximately 40% to 50%, and the same standards apply to diesel vehicles. Below is an introduction to China VI: Definition: China VI vehicles are those that meet the requirements specified in the "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)." Implementation phases: The China VI emission standard is implemented in two phases: Phase 1, starting from July 1, 2020, all vehicles sold and registered in China must comply with the China VI A standard; Phase 2, starting from July 1, 2023, all vehicles sold and registered must comply with the China VI B standard. Some cities may implement the China VI emission standard for light-duty vehicles as early as January 1, 2019.

What is the battery capacity of the Junfeng ER30?

This vehicle is equipped with a battery pack capacity of 31.82kWh. The model is positioned as a compact car, featuring the Venucia family-style design philosophy for its exterior. The headlight design on the front fascia is relatively simple yet delivers a strong visual impact. From the rear view, the car adopts a large-area full-glass tailgate, which gives the rear end a high level of recognition and excellent visibility performance. In terms of suspension, the front suspension of this car uses a MacPherson independent suspension, while the rear suspension employs a torsion beam non-independent suspension. The chassis tuning leans towards comfort, and the overall performance is quite commendable. Regarding power, the car is powered by a permanent magnet synchronous motor with a maximum power of 60kW and a maximum torque of 200 Nm. The transmission system is paired with a fixed gear ratio gearbox. The vehicle offers a maximum range of 255km, which can adequately meet daily driving needs.

What is the Vehicle Environmental Protection Standard?

China's emission standards are formulated with reference to European standards. Currently, common emission standards include National 5, National 4, National 3, Euro 5, Euro 4, Euro 3, etc. Starting from January 1, 2019, cities like Beijing will take the lead in implementing the National 6 emission standard. The following is relevant information about environmental protection standards: Purpose of Environmental Protection Standards: Vehicle emission standards are established to control the emission of pollutants from vehicles. They aim to curb the generation of harmful gases and encourage automobile manufacturers to improve their products to reduce the sources of these harmful gases. Stricter Environmental Protection Standards: Countries such as those in Europe and the United States have formulated relevant vehicle emission standards. These standards are continuously supplemented, refined, and tightened in response to the increase in vehicle ownership and the deterioration of the human environment.

How much antifreeze is needed at a time?

Generally, 5 to 6 liters are required, which should be added in two stages. Below is relevant information about antifreeze: Functions of antifreeze: The full name of antifreeze is antifreeze coolant, meaning a coolant with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions when the vehicle is parked, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. In cold weather, it prevents parts from failing or cracking due to cooling issues, manages rust prevention, and avoids excessive scale buildup that could clog pipes. It has functions including corrosion inhibition, scale prevention, boiling prevention, freeze protection, and rust prevention. Application of antifreeze: Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. Its freezing point varies with the concentration of ethylene glycol in the aqueous solution.

What does the safety valve discharge coefficient mean?

Safety valve discharge coefficient is the ratio of the actual discharge to the theoretical discharge of a safety valve, which is an important performance indicator of the safety valve, also known as the safety valve relief coefficient. Actual discharge of the safety valve: The actual discharge is the measured medium release quantity at the rated discharge pressure. Rated discharge of the safety valve: The rated discharge refers to the portion of the actual discharge that is allowed as the applicable benchmark for the safety valve. Theoretical discharge of the safety valve: The theoretical discharge is the calculated discharge of an ideal nozzle with a flow channel cross-sectional area equal to the flow channel area of the safety valve. Rated discharge coefficient of the safety valve: The rated discharge coefficient of the safety valve is the product of the discharge coefficient and the reduction coefficient (the reduction coefficient is generally taken as 0.9).

What are the precautions for long-distance driving?

Precautions for long-distance and highway driving: Pre-trip inspections are essential. Check the appearance and pressure of the tires, test the brakes, and listen carefully to the engine sound before entering the highway. Before a long-distance trip, inspect the following: engine oil, tires, dashboard warning lights, brakes, headlights, and coolant. Below is additional information about long-distance driving: Pay attention to engine oil: Before a long-distance drive, it is recommended to check the oil level to avoid insufficient oil. Use the dipstick to measure, ideally reaching the upper limit of the dipstick scale, and maintaining it between the middle and upper limits is optimal. Pay attention to tires: During prolonged driving, tires endure greater pressure compared to short trips, increasing the risk of a blowout. Always check your tire pressure before a long-distance trip. Pay attention to dashboard warning lights: Normally, there should be no warning or fault lights on the dashboard after the engine starts. However, if a fault light remains illuminated while driving, it indicates that the vehicle requires immediate inspection.
