In recent years, due to various factors such as environmental protection and rising international oil prices, various governments and auto companies have attached great importance to the development of new energy vehicles. The promotion and application of compressed natural gas (CNG) vehicles are generally considered to be energy-saving and emission-reducing and to reduce traffic pollution. A new approach has enormous potential for development and broad market prospects. Recently, the natural gas heavy truck designed and developed by SAIC Iveco Hongyan has passed the inspection in Chongqing.
The Hongyan Auto Compressed Natural Gas (CNG) heavy truck introduced this time is mainly developed for Thailand's export market, taking into account the domestic market demand to use compressed natural gas as fuel. The complete vehicle optimization integrates key components such as mature engines and gas systems. Among them, the entire vehicle mainly uses D6114 series gas engine produced by Shanghai Diesel Engine Company, Fast 9JS series transmission, Steyr dual-stage deceleration welding bridge, Xindakang T8 cab (including left and right steering wheel models), etc. . The vehicle is also equipped with a newly developed vehicle compressed natural gas supply system. The system is composed of gas cylinders, gas filling valves and Other high-pressure steel pipes, and can be equipped with 8--12 80 or 120-liter gas cylinders as required by users. In order to increase the cooling capacity of the engine, the vehicle also adopts a front-narrow, rear-narrow frame, and has made partial improvements to make the configuration shift smoothly, ensuring the safety of the cylinder and the reliable quality of the product.
As early as February 2007, SAIC Iveco Hongyan conducted a 10,000-kilometer road test on the first prototypes. At present, Hongyan Automobile has achieved the goal of mass production of natural gas heavy trucks.
At the acceptance meeting for the Hongyan Automobile Natural Gas Heavy Duty Truck Group, experts from the expert group carefully listened to the SAIC Iveco Hongyan Natural Gas Heavy Truck technical report and concluded that the Hongyan CNG heavy trucks independently developed by SAIC Iveco Hongyan It conforms to the national energy-saving emission reduction policy guidance, meets the national III emission standards, and adopts advanced electronically controlled pressure regulators and gas vehicle EMS control technologies. Its power performance is good, and its carrying capacity is strong. A sufficient and full mileage reaches more than 500 companies and reaches the domestic leading level. . The project has reached the national export mechanical and electrical product research and development requirements, the implementation of the contract funds project specifications. Finally, the expert group unanimously agreed to pass the acceptance check.
