The Yutong city bus is 10.5 meters long with a capacity of 79 passengers. Since it is a natural gas-electric hybrid bus, it has both LNG power unit and electric power unit. Moreover, the vehicles are also provided with engine intelligent start-and-stop technology and high-efficient electric power steering technology with the maximum electric power ratio of 51%.
Based on the related experiments conducted by the public transportation company, these city buses can save fuel by 20 percent compared with the conventional diesel ones, and reduce the annual carbon emissions by 50 tons.
Because no diesel is used, there is no black exhaust gas while stepping on the accelerator. It is learned beside the improvement of passengers’ ride comfort, the operation process of drivers have also become more intelligent, since the continuously variable transmissions and automatic control are adopted for all the vehicles.
