Research On Lng Vehicle Engineer Enclosure Eclectronic Control System

In recently years, it is more and more serious environment pollution situation in a lot of cities in China. It is an important reason that the automobiles let out the emissions. LEV(Low Emission Vehicle) is the vehicle which has low emission including LPGV, CNGV, Hybird car , electronic vehicle and other car which can take some ways to reduce the emission. With advancement of the emission ordinance and the fluctuation of the oil, the LEV has become an important way to solve this problem, to improve air quality and keep a health feature.This lecture places points on the research of the dual-fuel vehicles. It makes up of three parts.First, through making the model of the engineer, we can master and research the basic control mechanism, control mind, and electronic control ways. And find the most fit to LPGV.Second, learning development of LPGV and the new trend of it, then introduce three control ways of it. The electronic enclosure control way of LPG fits to our country situation. It uses electronic control technology and places an oxide sensor in emission system, then according to the change of the rate of the air to fuel, adjust automatically the ejection of fuel. So it can improve dramatically the automobile performance. After installing three-way catalytic converter, it can make the pollutions lower 20%~50% than the same vehicle, and the power of car reduce only 5%.Last, it mostly introduces structure and working mechanism of LPGV and research accessory how to design and work, including the cylinder for vehicle, cylinder accessory, the pressure regulator, and injector simulator. Finally, do an experiment to testify the injector simulator.In a word, it includes the electronic control theory, the mind to design it, and the design way of its accessory. As the first research in our country, it can accelerate the fuel-gas automobiles development, and improve the air quality in city. It will have a great value, a bright future.
