English                         Chinese

is a dedicated three-dimensional engine analysis tool essential to the design and development of the crank train, engine structure and associated components such as bearings, connecting rods and engine mounts. By offering a range of levels of complexity of components, oil film models and solvers, ENGDYN can be used throughout the entire development programme, from concept through to production.
