The factory system period Gas vehicles mainly include liquefied petroleum gas vehicles (LPG vehicles or LPGV) and compressed natural gas vehicles (CNG cars or CNGV). As the name suggests, LPG cars are fueled by liquefied petroleum gas (LPG) and CNG is powered by compressed natural gas. The CO emission of gas vehicles is more than 90 percent less than the gasoline car, the hydrocarbon emission reduction is more than 70 percent, and the nitrogen and oxygen emission reduction is more than 35 percent, which is the current relatively practical low emission vehicle. The development of automobile modeling was better aerodynamic design combined with seating comfort to be properly, in full consideration to the above two key problems, on the basis of efforts to develop new technology in the field of human body engineering, in order to design and make cars more perfect, more outstanding for the target. One day, the car cab will form a "glass cover" with beautiful curves. It is reflected in the geometry of the body, the round and the streamline. At that time, the paint of car colour will reflect soft feeling and transparent feeling in the bright-coloured, so will be more pleasing to the eye.
