HIL COMPATIBLE ENGINE MODELS FOR DUAL FUEL APPLICATIONS

Artigo Completo:

More and more, alternative fuels, fuel mixtures and dual-fuel engines are gaining in importance. This means a huge challenge to thermodynamic modeling of combustion and species transport. The computational performance is reached by an optimized filling and emptying approach applying tailored models for in-cylinder combustion and species transport in the gas path. The impact of the thermodynamic characteristics induced by the different fuels is described by an appropriate set of transport equations in combination with specifically prepared property databases. The accuracy of a lumped fuel approach is compared for a six, three and one species transport. The simulations are performed with a 6 cylinder medium speed engine. The real-time factor of this engine is in the range of 0.2 for all species transport approaches, what enables this method to support HiL based function development and calibration.
