Development of a Hybrid Power Unit for Formula SAE Application: ICE CFD-1D Optimization and Vehicle Lap Simulation 2019-24-0200

The paper reviews the CFD optimization of a motorcycle engine, modified for the installation in a hybrid powertrain of a Formula SAE car. In a parallel paper [Development of a hybrid power unit for Formula SAE application: packaging optimization and thermo-mechanical design of the electric motor case], the choice of the donor engine (Ducati 959 “Panigale”) is thoroughly discussed, along with all the hardware modifications oriented to minimize the new powertrain dimensions, weight and cost, and guarantee the mechanical reliability. In the current paper, the attention is focused on two main topics: 1) CFD-1D tuning of the modified Internal Combustion Engine (ICE), in order to comply with the Formula SAE regulations, as well as to maximize the power output; 2) Simulation of the vehicle in racing conditions, comparison between a conventional and a hybrid powertrain
