Abstract:
Diesel engines nowadays are faced with enhanced emission standards, which limit further improvements in fuel economy. In order to meet future emission regulations in a cost-effective way, high levels of EGR are needed. One way of increasing the level of EGR with current technology boosting systems is to utilize low pressure loop EGR. This paper discusses the benefits of low pressure loop EGR as well as some of the challenges. A new component is presented which overcomes some of these challenges. Also, modifications to current technology compressor wheels are presented, which enable the compressor wheel to survive ingestion of exhaust gas.
