Vigorously developing new energy sources is a major task for Weichai in implementing green environmental protection in recent years. Weichai has made substantial progress in the past year of 2012 by creating a new energy-driven, low-carbon, environmentally friendly and efficient industrial chain. The engine -motor-transmission green industrial chain has provided new energy vehicles with strong power for system, high-efficiency, energy-saving, and environmental protection.
As early as the first half of 2012, Weichai Power introduced a new energy "WN20" powertrain. The new energy “WN20†powertrain adopts a low-carbon and energy-saving modular design, which allows the vehicle to select and distribute the mixed 4-12 liters of diesel or natural gas, the national IV engine and the 5-16 gear, with minimal modifications. Automatic transmission system assembly. The assembly is applied to buses of 10-12 meters and its fuel saving rate can reach 30%. Taking this as a sign, Weichai has made substantial progress in building a new energy power drive for a low-carbon, energy-saving, and emission-reducing high-efficiency industrial chain.
Weichai New Energy Technology Center has developed a series of core technologies featuring electric power and electronic control through independent innovation and established a common technology platform for hybrid powertrains for commercial vehicles and construction machinery. Through the development of the hybrid powertrain assembly, it has been applied to the fields of hybrid power loaders, excavators, bulldozers, large passenger cars, heavy trucks, etc., enabling China's commercial hybrid power technology to reach the international advanced level and achieve industrialization.
It is understood that after mass production of hybrid products is achieved, within the scope of technical application, fuel economy can be improved by more than 30% and emissions can be reduced by more than 30%. The power system is mainly applied to buses of 10-12 meters. According to tests conducted by China’s authoritative inspection department, buses assembled with Weichai New Energy’s electric powertrains can be directly reduced by driving 400,000 kilometers over 8 years under the conditions of GB/T19754-2005 typical urban public transport cycling in China. Carbon dioxide emissions of 80 tons, saving rate of 30%. Weichai Power New Energy has achieved tangible results in boosting energy conservation and emission reduction.
