As China's economy continues to grow, there is demand for faster and more reliable rail transportation. Dalian Locomotive and Rolling Stock Works (DLW), the People's Republic of China's largest locomotive manufacturer, joined with Southwest Research Institute (SwRI) to design a high output, minimum weight, robust diesel engine to be used in a new class of locomotives. The new 12V280ZJ engine is rated 4410 kW at 1000 rpm and was designed as a "clean sheet" engine using the most current computer-aided design and analysis tools and procedures. The engine configuration uses state-of-the-art designs for the major components and subsystems in order to meet emissions, performance, reliability, and low maintenance cost goals required for next generation locomotives.
