VTG turbocharging - a valuable concept for traction application
Greater demands are being placed on railway engine applications as the impact of rising fuel prices underscores the need for more efficient solutions while, simultaneously stricter emission legislation comes into effect. With focus on these two challenging aspects, existing and upcoming engine power-packs still need to cope with the known specifics of traction applications in terms of high reliability, long durability and operation in an extremely wide range of ambient and load conditions. This paper describes how ABB turbocharging products and related concepts support railway engine builders and operators in ongoing and future engine development as well as in upgrading existing platforms. After a brief review of ABB dedicated rail turbocharger platform, TPR, the focus will be on newly developed VTG technology and its related control unit. Tangible results to improve fuel efficiency and to enhance operating flexibility will be evaluated with alternative solutions. The paper presents a proposal to cope with stricter emission legislation with minimum fuel efficiency compromises. A concept is described by which the VTG turbocharging module is deployed to realize external cooled exhaust gas recirculation in combination with a high speed electrical blower. ABB VTG turbocharging module, when applied on the TPR platform, enables significant fuel economy on existing and upcoming engine platforms, while increasing the operating range of traction applications. It is a base for promising concepts targeting stringent emission legislation with positive effects on traction economics.
