Abstract: To meet the demand for high reliable power by 9000-meter electric drill rigs, offshore platform and large diesel gensets, replace the imported products and solve the bottlenecks in development of petroleum equipment, CNPC Jinan Diesel Power Equipment Company has developed H16V190ZL diesel engine which is supercharged, large-powered, low fuel-consuming, highly reliable and long in service life. The feasibility of diesel engine research and development was determined on the basis of investigation. Simulation analysis, such as BOOST and EXCITE, was used to design and calculate the general performance of diesel engine, turbocharged exhaust system, main part finite element, axial system, air distribution system and cooling and lubricating system, with the research and development targets determined. Maintenance and appearance of the whole engine was taken into full consideration while guaranteeing its structural reasonability and compactness. Manufacture of the prototype, type test and experiment of its performance were completed on the basis of optimized process design. All the indexes of performance reached and exceeded the designed standards, according to the results of experiment. Up to now, 116 diesel engines and generating units have been sold on the market, generating sales income of 180 million yuan. H16V190ZL diesel engine was a domestic leader and reached the world’s advanced level in terms of dynamic power, economical property and reliability.
