Study of Combustion and Emission Characteristic of Homogenous Charge Compression Ignition Engine Using Computational Fluid Dynamic

摘要: Numerical methods are used to predict HCCI engine performance, which is more cost-effective than experimentation alone. Specific strategies numerical in an with three-dimensional modelling of combustion on 1 cylinder fuelled by Diesel fuel described this paper. The 3 D model performed AVL Fire software. basic parameters including different start time Injections (SOI) the same duration (BD), indicating pressure chamber and emissions (Nitric Oxide soot) were evaluate. results show that highest value method was achieved at a 107 bar 360 deg CA, while conventional it 72 363 CA. On other hand peak heat transfer rate 127 J / 10 BTDC, whereas for occurs 32 1deg ATDC. So there shift toward BTDC before TDC, due already homogeneous method. process engines increases high NO reduces Soot emissions.
