Abstract:
In order to improve the performance of previous season 600cc Yamaha YZF-R6 Formula Student air-flow restricted racing engine, an intensive research in developing a trustworthy engine mathematical model, using 1D thermodynamic Ricardo WAVE® simulation environment was carried out. The Internal Combustion Engine Department has provided simulation software and equipment for in-laboratory engine testing. Data acquired during last season control parameter optimization process (ignition and fuelling main maps) on the engine test bench was used to calibrate the combustion model. Research was based on engine effective parameters, because crank-angle-resolved cylinder pressure measurement was not carried out. Engine work cycle simulation results analysis and combustion parameters decision-making process were processed using MATLAB® in-house developed code. The engine model with recalibrated combustion parameters was used for assessment of characteristic geometrical dimensions for the new intake manifold. After this season’s engine retesting, the collected data was used for validation of combustion and induction system mathematical models. Using this approach for intake manifold design we were able to simulate various design concepts in an effective and fast manner.
