The 4000 series long-stroke diesel engine is based on the current status of the internal and external combustion engine industry in China and abroad. It has been disign and develop under accumulated many years of product R&D experience and collaborated with domestic universities and research insitutes combined with the Austrian AVL simulation analysis software. It better combustion can be organized at lower speeds to increase power and reliability of utilize and reduce fuel consumption. Its main technical indicators such as power performance, economic performance and reliability of utilize have reached international standards.

This series of diesel engines has the advantages of compact shape, simple operation and maintenance, and high power index. The supporting products can meet the power demand of mechanical drilling rigs. It can also be matched with 50Hz and 60Hz power frequency generators to meet various power needs.
