This paper will present the most important tools and features required for the development of the FO110 3.0L V10 Mercedes engine.
The demands on the natural aspirated 3.0L gasoline engine are discussed by the use of recorded data from trackside. Based on these findings the most important measures to achieve maximum power output and drivability will be discussed. The presentation will mainly focus on the thermodynamic and gasdynamic aspects of the V10 engine to ensure optimum volumetric efficiency. This includes the tuning of the inlet and exhaust system as well as optimisation of valve timings and combustion analysis work. The used simulation and measurement tools are discussed and the most important parameters will be investigated in detail. The advantages and the limitations in terms of accuracy and sensitivity of simulation programs and used measurement technology, applied in high revving race engines, will be shown.
Finally, there will be a prediction of future development strategies, seen from the thermodynamic point of view.
But, we should like to point out, that - due to the intense competition - no design or other technically related details can be published in this paper.
