... of turbocharged diesel engines could be improved by electric assisting systems, either by direct energy supply with an integrated starter-generator-booster (ISG) mounted on the engine flywheel, or indirect energy supply with an electrically assisted turbocharger. A previously verified zero dimensional computer...

... that does not utilize the one-way-coupling assumption. The model is based on fully coupled rigid-body dynamics for the pistons, connecting rods, crankshaft, flywheel, and engine block. Predictions from the new model are compared to those from an equivalent one-way-coupled model for poorly balanced (one...
