Tianda Diesel Engine Energy Saving and Emission Reduction Technology won the second prize for technical invention

Applying the new energy-saving and emission-reduction technology developed by Tianjin University, it can save the equivalent of a small and medium-sized oil field. At the National Science and Technology Awards Conference recently held, the two projects led by Tianjin University won the second prize for the 2010 National Technology Invention Award and the second prize for national scientific and technological progress.

According to reports, Tianjin University was the first completion unit and Prof. Su Wanhua and others mainly completed the “Diesel Fuel Mixing Rate and Chemical Reaction Rate Cooperative Control Technology and Application” project, which changed the traditional diesel combustion technology, through chemical reaction rates and The coordinated control of the mixing rate allows the combustion process to develop toward a highly efficient and clean combustion path. The results are applied to diesel engines, which can reduce the cost of diesel engines by more than 30% and fuel economy by 5%. At the same time, it is possible to meet the national IV and national V emission standards without exhaust gas after-treatment devices and to break through the foreign technical route that relies on exhaust gas purification equipment. At present, the results of the project have been applied in 13 series of diesel engine leading enterprises such as Weichai and Yuchai, and the fuel saving in the past three years reached 8 million tons, which is equivalent to the storage capacity of a small and medium oil field.

The project “Comprehensive Technology Evaluation Method for Complex Power Distribution System, System Development and Engineering Application”, with Tianjin University as the first completion unit and Professor Wang Chengshan, has been implemented in 29 provinces and cities in China. In the successful application, the market share of the developed system is the first in the country, and the research results have reached the international leading level, which has played a huge role in promoting the technological advancement of the distribution system in China.
