8, the development of exhaust after-treatment technology. When emissions regulations to further strengthen the laws and regulations of the European II standards, the need for a plane, on the purification measures, including exhaust gas recirculation, oxidation catalyst technology, from NOX catalyst.

9, promote the use of spray-cylinder gasoline engine technology. Gasoline direct injection gasoline engine is substantially improve fuel economy and reduce harmful emissions of effective measures. At present, Japan has come out products.

Promote the use of clean energy in the internal combustion engine (LPG and CNG and other alternative fuel engines). Motor vehicles are the main urban air pollution sources, in addition to continuously strengthen the internal combustion engine vehicle emissions regulations, as far as possible to reduce their harmful emissions, the use of cleaner fuels is an effective measure to make major emissions reduced by 30% -90%.
