Coupled 1D/3D Analysis

VECTIS is fully integrated with WAVE, Ricardo’s 1D gas dynamics software, allowing 1D/3D-coupled analyses to be performed effortlessly. VECTIS can also be used in conjunction with many other 1D packages.

Development of intake runner systems can be performed to investigate ways of improving mixing, reducing cylinder-to-cylinder variations in air/fuel ratios and exhaust gas recirculation (EGR). The location of EGR pipes and their design can be determined and the dynamics of the intake system can be optimized

This analysis approach can also be used on exhaust components. Exhaust runner lengths and catalyst cone designs can be investigated and Lambda sensor locations can be determined. Aftertreatment simulations can also be performed looking at catalyst utilisation and light off potential as well as Selective Catalytic Reduction system design
