At the Guangzhou Auto Show just past, Yutong’s new 12-metre replacement model ZK6122HQCA was unveiled for the first time. It features low fuel consumption, beautiful interior and exterior decoration, comfortable ride, and high safety. It was also known to the media and the public for the first time. According to Yutong booth staff, the vehicle is only one of Yutong’s 12-meter replacement models. The 12-meter replacement model has four models of two different interiors: the economic version and the deluxe version. Among them, two models complying with the national 3 and 4 emission standards are mainly for the travel and group bus markets, and the passenger transport version of the passenger transport market is the top ten. The new two-meter car will also be launched in the later stages.
From the auto show scene, this brand-new 12-meter car looks handsome and refreshing, giving people a sense of luxury and luxury. The headlights are made of light-shell-free primer-coated matte, which is the first time in the passenger car industry. The headlights are equipped with a dual-beam configuration, the low-beam headlights have an electric height adjustment device, and the combined headlights incorporate LED lights... a series of innovative designs that ensure night-time safety and enhance the appearance of a sense of dignity. The side design of the car body is even more distinctive, and the door at the waist beam and the side skin are used to form a new type of handle-type metal lock, which is easy to operate. Side fork-shaped decorative parts and body shape organic integration, totally natural.
Safe and comfortable three-dimensional upgrade Create new standards of quality
The 12-meter new car is designed to meet the ergonomic principles in the driving environment and space layout. By measuring and counting the driver's height and shape, the optimal seat position and position of pedals, switches and controllers are designed. Distribution, to ensure control and convenience, and improve driving safety. At the same time equipped with upgraded seats and electronic refrigerators, increase the space inside the car to greatly enhance comfort. In addition, the application of 3G network technology has enabled wireless Internet access for mobile phones and computers in the car, providing passengers with more extensive travel entertainment functions and convenient data support services.
Not only is comfort significantly improved, but innovative applications at the security level are even more commendable. First of all, the front axle adopts the imported disc brake, which has the advantages of short braking distance, fast heat dissipation, etc. It is equipped with an ABS anti-lock braking system to ensure the brake safety of the vehicle. Secondly, after four rounds of simulation analysis and testing, the stability of operation has been significantly improved. Thirdly, the high-strength steel is adopted for the body frame structure. After CAE analysis and roll-over tests verify that the safety meets the requirements of European ECE R66-01 regulations, a complete living space can be maintained even if the vehicle rolls over. Once again, the safety of electrical components has been fully improved. The protection design of tin-plated flame-retardant copper wire, imported waterproof connectors, engine compartment battery wires and battery compartment harnesses has been used to improve the stability and durability of wire harnesses. In addition, ESC/ESP, EBS, ACC, lane departure, collision alarm, and axle load display system can be installed to fully enhance vehicle safety, comfort, and economy.
Comprehensive improvement of energy saving and environmental protection
In today's vigorous promotion of energy saving and emission reduction in the country, the energy-saving and environmental protection of buses is also an important assessment indicator for customers' car purchase decisions. Yutong's new 12-meter car gathers energy-saving technologies and environmental protection technologies to create a stylish, smart, green, low-carbon life.
Innovative technology makes energy saving even better. The new 12-meter vehicle adopts Yutong's original integrated cooling unit system technology to save energy and reduce noise, creating greater value for customers. At the same time, adding vibration-reducing rubber sleeves to the rotating shaft of the compressor bracket can reduce the noise of the entire vehicle by 2-3dB, providing a more amiable driving experience for the driver and passengers. In addition, the instantaneous fuel consumption and cumulative fuel consumption display functions are increased, and the energy saving can be implemented into the details of actual driving by changing the driving habits of drivers to reduce fuel consumption.
Environmental technology makes travel more healthy. Yutong's 12-meter new car interior adopts environmental protection materials, and the front and rear roof trim parts are made of flax material. The luggage rack adopts integral PU foam parts, which is more healthy and environmentally friendly. The floor installation uses floor leather adhesive to bond directly to the outside. It is not necessary to spray glue again in narrow cars, which greatly reduces car odors and harmful gases. What is most worth mentioning is the “new air†button added to the air-conditioning panel, which allows air to be ventilated when the compressor is not in operation to ensure that the air is fresh and natural, and that the air environment inside the vehicle reaches the interior standard of the home improvement.
The upcoming new Yutong 12-meter car will combine safety, comfort, energy saving and environmental protection with its excellent pedigree, external elegant design and rich internal configuration. It will surely set off an upsurge of sales in the domestic high-end bus market.
Compound fertilizers are chemical fertilizers made by chemical methods or/and mixed methods containing any two or three of the nutrient elements of crops, nitrogen, phosphorus and potassium. Its role is to meet the comprehensive needs and balance of multiple nutrients needed by agriculture under different production conditions. It is widely used in modern agriculture.
Due to the needs of agriculture, compound fertilizers, especially high-concentration compound fertilizers, are an inevitable trend in the development of Chemical Fertilizer varieties. The early fertilizer industry in most countries was dominated by fertilizers in the production unit (fertilizers containing a nutrient). With the development of soil fertilizer science and agricultural fertilization technology, agriculture has moved towards scientific fertilization. Scientific fertilization must be based on different soil types and properties, fertility levels, crop types and climatic conditions and other factors to determine the variety and quantity of fertilizer, so that the excessive application or shortage of one or more nutrients in the soil and waste.
The content of each nutrient element of the compound fertilizer is generally expressed in the corresponding percentage of N–P2O5-K2O, and its sum is the concentration of the fertilizer. According to Chinese standards, the total content of 25% to 30% is a low concentration, 30% to 40% is a medium concentration, and more than 40% is a high concentration compound fertilizer. Compound fertilizers can evenly supply several nutrients to crops at the same time, so as to give full play to the mutual promotion of nutrients. Because of its different production processes, it can be divided into three categories: compound fertilizer, compound fertilizer and mixed compound fertilizer.
