World's Most Powerful Four-Stroke Engine

摘要

MAN has revealed the latest addition to the company's 4x line of high-performance diesel engines: the MAN 20V45/60 comes with a limit-pushing power output of 26 MW. Furthermore, the company was able to considerably reduce fuel consumption compared to its predecessor, the MAN 48/60. »Next to a frontloading approach, using thermodynamic engine process calculations, we used computational fluid dynamics to simulate and optimize the combustion process. Also finite elements analysis was used to optimize the engine's mechanical strength and vibration behavior. We then put the power unit to the test on the world's largest four-stroke, single-cylinder test bed and started the experimental optimization and validation phase«, said Dr. Gunnar Stiesch, Head of Engineering Engines at MAN Diesel & Turbo.
