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 company's compressed natural gas (CNG) heavy trucks are mainly developed for the Thai export market, and take into account the domestic market demand for 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 consists of gas cylinders, gas filling valves, etc., which are connected by a high-pressure steel pipe. Eight to twelve 80- or 120-liter gas cylinders can be installed according to user needs. 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, the company carried out a 10,000-kilometer road test on the first prototypes. At present, the company has achieved the goal of mass production of natural gas heavy trucks.
After the company's natural gas heavy truck inspection at the meeting, the group of experts in the relevant technical reports listened carefully to the heavy truck natural gas company that SAIC Iveco Hongyan Hongyan company developed a compressed natural gas (CNG) heavy truck cars in line with the national energy saving Policy-oriented, to meet the national III emission standards, the use of advanced electronically controlled pressure regulators and gas vehicle EMS control technology, good dynamic performance, bearing capacity, a full and maximum mileage of more than 500 companies, reaching the leading domestic 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.
