Abstract
In this study, one-dimensional analysis using AVL Boost software has been carried out on a series of compression and spark ignition engines utilizing a manufacturer fitted single-entry turbocharger and a modified twin-entry unit, the latter adopting two symmetrical turbine housing inlet ports. The model reconstruction using AVL Boost considers parameters that accurately represent the physical engine conditions including manifold geometry, turbocharger flow maps and combustion chamber characteristics. Model validations have been made for a standard single-entry turbocharger configuration to predict the maximum engine power and torque, in comparison with available manufacturer data and analytical calculations. Further studies concentrate on engine performance comparisons between single- and twin-entry turbochargers at low engine speed conditions, typically in a range of 1000–3000 RPM. Improvements in turbine shaft speed, engine power and torque have been achieved, thus implying improved low speed engine response. This study reveals the potential commercial benefits of adopting a twin-entry turbocharger and contribution to the academic community through this additional research.
