Protect the blue sky, symbiosis with the nature
SAIC Hongyan has always fulfilled environmental responsibility. It not only established the world first-class environment-friendly heavy vehicle factory synchronous Europe but also manufactured a series of environment-friendly heavy vehicles with European advanced technology in product research and development (R&D) and manufacturing, to promote the harmonious and sustainable development between enterprises and the environment.
Ultra-low noise to reduce noise pollution
SAIC Hongyan heavy vehicle series adopt cursor series engine of European standard. It is designed of top camshaft structure with compact structure, less number of parts, no drive clearance, thereby can reduce the mechanical noise effectively; four-valve technique, unobstructed intake and exhaust can reduce gas noise effectively; the rear gear system and adjustable gear clearance can reduce the gear rotation noise effectively; the usage of new material and roller rocker also can reduce the friction and metal noise. Besides, the excellent cab tightness of SAIC Hongyan heavy vehicle series can reduce the noise utmost. According to the experimental test, the constant speed indoor noise of Genlyon products is 68+2dB (the domestic standard is 90dB), and the outdoor noise is significantly 3-5 decibels lower compared with similar products. The advanced noise-reduction techniques generate tangible results in reducing noise pollution.
Minimum emission to reduce exhaust pollution
Engine exhaust emissions mainly include two substances of NOx(Nitrogen oxides) and PM(Particles), and they cannot be removed simultaneously because of the chemical properties of the two. As a result, two main engine emission control methods occur: SCR(Selective catalytic reduction) and EGR( Exhaust gas reclrculation). The two patents as Prediction algorithm of electric control strategy and Dynamic fluid design of mixing cavity of HI-eSCR technique researched and developed independently by Fiat power technique ensure the good performance of HI-e SCR system in emission control. The advantages of HI-e SCR are obvious, by using SCR technique only, the engine structure is compact, light and easy to maintain, and since it is not necessary for exhaust gas recirculation, this makes the engine burn more efficiently, thus can provide with greater power and torque density and lower fuel consumption, thereby present excellent emission performance.
Utmost clean operation for clear water and blue sky
In SAIC Hongyan heavy vehicle family, new Hongyan intelligent environmental protection muck truck also contributed to the environmental protection in urban construction. It was designed of fully enclosed electric top-cover to avoid effectively the occurrence of dust, leakage, scatter and so on during transportation. The one-piece side coaming can prevent the muck stuck in the truck body, tire and tank accessories during loading and unloading cargos to achieve no accumulation of the truck body, thereby more cleaner and more environment-friendly.
Be warm-heated, show great love
It established a Student aid fund to help children from poor families to go to school. Also donated to help the schools of San Tin village, Tengen town, Wuxi county, Chongqing, Wood village, Baojia town, Pengshui county, Chongqing, Third work area, Cuili town, Congjiang county, Guizhou and so on to improve the schoolhouse conditions, buy more study articles thus help students to fulfill their academic dreams. Meanwhile, it fulfills public welfare, not only contribute to greening the Yangtze River, protecting the mother river but also propose water environmental protection in the World Water Day. SAIC Hongyan equally spared no effort to donating, organizing vehicles to participating in rescue in earthquake relief work, flood fight, etc.
