• SIMULATION ON SINGLE CYLINDER DIESEL ENGINE AND EFFECT OF COMPRESSION RATIO AND EGR ON ENGINE PERFORMANCE AND EMISSION

    Machines. Technologies. Materials., Vol. 9 (2015), Issue 2, pg(s) 24-26

    In this research, the one dimensional (1D) CFD modelling of four-stroke direct injection diesel engine is developed by AVL Boost software. The performance of a diesel engine increases with increase in compression ratio. Variable compression technologies in IC engines are used to increase fuel efficiency under variable loads. Exhaust gas recirculation is a common way to control in-cylinder NOx production and is used in most modern high speed direct injection diesel engines. However the effect of EGR on performance, combustion and emissions production at different compression ratios are difficult to depict. In the present work an attempt was made to study the effects of exhaust gas recirculation on performance, combustion and emissions of a variable compression Diesel Engine. The test was conducted at different compression ratios with different loads and for different EGR rates.

  • SIMULATION ON SINGLE CYLINDER DIESEL ENGINE AND ESTIMATION OF ENGINE PERFORMANCE USING AVL BOOST SOFTWARE

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 7, pg(s) 33-35

    The simulation and computational development of modelling for the research is use the commercial Computational Fluid Dynamics (CFD) of AVL Boost software. In this research, the one dimensional (1D) CFD modelling of four-stroke direct injection diesel engine is developed. The analysis of the model is fluid flow and combustion performance process in the engine cylinder. In this model it can to know the diesel engine performance effect with simulation and modelling in any speed (rpm) parameters before to do the physically development, so it can do the new engine design components with the economic material and time. The model simulation covers the full engine cycle consisting of intake, compression, power and exhaust. The simulation result highlighted energetically and economic performance of the engine.
