Aspects of a Tier 4 development for a multi-application high speed Diesel engine

摘要：

　　High speed engines typically are used for multi-application operation as e.g. locomotive, marine, electric power generation, electrical drilling and other non-road usage for example mining trucks or well fracturing. The present performance and emission development of these engines implies the necessity to fulfill on the one hand the fuel consumption targets, which are usually lower than the existing series production. On the other hand limiting cost factors as hardware communality and production line capability and hardware limits as peak firing pressure or turbocharger availability have to be taken into account. Beside these facts user acceptance for the different technology routes exhaust gas recirculation, exhaust after treatment or dual fuel operation make the engine developer’s job more and more challenging. Nevertheless the optimum solution for an engine platform has to be worked out without accepting too many compromises. This article will discuss typical aspects and boundaries for a TIER 4 development of a multi-application high speed Diesel engine with exhaust gas recirculation as well as SCR technology.
