China's first full-bearing natural gas bus in Changlong off the assembly line


The 10-m full-loaded natural gas bus independently developed by Jiangsu Changlong Bus Company was launched on the Changfeng line in Jiangsu Province. This is a new energy source with the characteristics of the times developed by Changlong Company in response to the national energy conservation and environmental protection strategy and efforts to build urban green traffic construction. bus. The first batch of 209 vehicles will serve the Yangtze River Delta star city, Jiangyin City, the top 100 counties in China.

Changlong YS6990NG new type of natural gas bus , based on the overall design ideas, according to the international synchronization technology and combined with the actual development of large and medium-sized cities in China independently designed and developed, not only novel, generous appearance, but also comfortable ride, at the same time, the design of the vehicle And installation fully reflects its safety features. Its key assembly adopts the most advanced and mature technology devices in the country. In order to ensure the safety of passenger cars, safety is not only reflected in the design of the body, frame, assembly, and interior parts, but also in the layout of the passenger car, such as the secure installation of gas cylinders and the use of full load bearing structures. The advantages of scientific design, improve the safety of natural gas use, and fundamentally eliminate the unsafe factors caused by vehicle collisions. In particular, heat shields, gas leak alarms and other technical devices better ensure the safety of gas cylinders.

Due to the design in accordance with international environmental standards, it is completely non-sulfur, dust-free and pollution-free in terms of clean and environmental protection. Its environmental protection standards fully meet international advanced environmental standards.

The clean energy passenger car powered by natural gas is currently the most environmentally friendly and most energy-efficient type of passenger car. Natural gas vehicles have a 90% reduction in carbon monoxide emissions compared to fuel vehicles, and hydrocarbon emissions and nitrogen and hydrogen emissions are also lower than those of fuel oil. The cars were lowered by 70% and 35% respectively. In addition, the air engine has lower noise than ordinary diesel engines. This is quite attractive for areas with high exhaust emission requirements. At the same time, it is also in line with the general trend of urban environmental protection in China. Therefore, whether it is from the urban government responsibility, or from the perspective of sustainable development and profitability, natural gas buses have incomparable advantages.

Natural gas-fueled clean energy buses do bring many benefits to customers. The most direct is to save money. Compared with ordinary diesel-powered buses, the use cost of natural gas vehicles can be much lower than that of ordinary diesel vehicles. The natural gas buses developed by Changlong have lower operating costs. According to calculations, if the current fuel consumption is 35 liters per 100 kilometers, natural gas vehicles per 100 kilometers will save 42.5 yuan more than diesel vehicles. If each car runs 250 kilometers per day, the annual output Car 300 days calculation, then each car can save 31,875 yuan per year. And can greatly reduce the city's harmful gas emissions.

It is understood that Changlong's new natural gas buses have low maintenance and maintenance costs, are easy to maintain, have good cold start performance, and are stable in operation. At the same time, they use scientific design ideas to damage components such as cylinders, pistons, piston rings and valves. The noise is also 40% lower than that of a fuel-powered vehicle. The engine has a long life. The vehicle overhaul mileage can be increased by more than 20%. There is no need to change the oil and spark plugs frequently, and it can save more than 50% maintenance cost compared to using oil fuel.

Changlong's new YS6990NG passenger car has just been successfully trial-produced, and it has been favored by users. Bus companies in Jiangyin and other places in Jiangsu have come to the forefront. They are very interested in Changlong Bus . They believe that Changlong Company fully develops new types of clean energy passenger car products from the perspective of users and passengers. At the same time, it uses the international advanced full load bearing technology to the new energy passenger car and is very suitable for the metropolis. The needs of the development of green transportation also comply with the direction of the development of public transport, and will guide the healthy development of urban public transport and become a new star in urban public transport.



CHANGLIN brand Pneumatic Rubber Fender is one of the Jinan Changlin's major products. It has the merits of high pressure resistance, high energy absorption, low reaction force, aging resistance and seawater corrosion resistance. during the standard preparation, compression performance tests were made by Shandong University Mechanical Engineering test center.  Could be compare with Yokohama Type Fenders, our company also made the GB/T 21482-2008, The Reliable data proved that products quality performance parameter have reached or was high than the requirements international standard. At present, CHANGLIN brand Pneumatic Rubber Fenders were widely used to various ships, offshore platforms, wharfs and floating docks for collision protection at local and abroad.
