Simulation on thermal performance parameters of gas-fired in cylinder based on Boost software

Using Boost module of AVL software, a simulating system for modeling working procedure of engine was established. On the base of zero-dimensional combustion model, dependent on structural and thermodynamic parameters of engine, applied Vibe heat release model and WOSCHNI 1978 heat transfer model, the working procedure of engine was modeled. By optimizing specified performance parameters of engine, a satisfying simulating system was set up, and then thermal performance parameters of gas-fired in cylinder were obtained, which can provide heat transfer boundaries for further calculating cylinder head temperature field.
