Great Progress of China Engine

English.chinabuses.com: With the progression of China's reform and opening-up policy, many technology transfer projects took place involving joint ventures or external wholly-owned entities producing advanced engine models by advanced processing methods and imported machine tools.
Yet, the core technology can hardly be mastered simply through technology transfers or technical cooperation, in certain cases even special restriction clauses were stipulated in the contracts. The core technique of diesel engines - electronic controlled common rail system - is still mastered by multinational companies. For developing new products, domestic companies mainly rely on the support of world's leading multinational companies such as AVL, FEV and Ricardo.
The situation is changing gradually. According to figures from China's State Intellectual Property Office of China, the number of patents related to internal combustion engines is almost 5,900 now, nearly 10 times the number 10 years ago. Advanced Western engine technologies, including adiabatic ceramic, cylinder cut out control, intelligent valve and variable compression ratio, have drawn the attention of some domestic companies and scientific research institutions and some have already begun developing these techniques.
