**Project and scope summary**This project addresses the specific competition theme as a technology solution to substantially reduce emissions including NOx and PM when diesel passenger trains are idling. It shall deliver a cost effective retrofit solution to a significant proportion of existing DMU's, whilst providing potentially zero emissions within station and significant operational cost benefits.The technology, which does not require any modification to the existing engines, transmission or final drive, allows the recovery of the braking energy during deceleration and re-using it for auxiliary loads in station and traction to accelerate out of station. This will enable diesel engines to be isolated in and around stations, whilst also reducing average emissions such as PM and NOx and fuel consumption, over a complete drive cycle, by up to 30%.This project will enable several key cost and decarbonisation benefits to the railway.* It shall facilitate zero emissions, including NOx and PM, in and around the station, by enabling a DMU to approach, dwell and depart from a station with the engine switched off* It shall enable a proportional average reduction in all emissions, through reduced fuel consumption resulting from the electrical energy recovery from regenerative braking and re-deployment through auxiliary and traction use* It shall enable less brake wear thus reducing particulate emissions from brake pads especially around stations* It shall enable reduced operating costs for the train operator through fuel saving, engine/transmission maintenance savings and brake pad saving* It shall provide increased acceleration and reduced wheel slip due to increased number of powered axles during acceleration* It will not require any modification to the existing diesel engines or drivetrain and will compliment any other decarbonisation initiatives.* It shall provide a substantially lower cost and risk solution when compared to any other previous or current hybrid solutions, resulting in a much reduced ROI.This solution is equally beneficial in a freight wagon application , whereby significant cost and emission savings can be realised, whilst also potentially delivering increased average freight speeds and traffic, last mile operation, increased acceleration, and longer trains.The commercial and environmental potential from the design and validation of such an innovative, low cost solution, provides the opportunity for the rail industry to transform many legacy passenger fleets and freight operations within a 5 year window on the majority of fleets.

**项目和范围摘要**该项目针对特定的竞赛主题，作为一种技术解决方案，在柴油旅客列车空转时大幅减少氮氧化物和颗粒物等排放。它将为大部分现有 DMU 提供具有成本效益的改造解决方案，同时提供站内潜在的零排放和显着的运营成本效益。该技术不需要对现有发动机、变速箱或最终传动进行任何修改，允许减速时回收制动能量，重新用于进站辅助负载和出站牵引加速。这将使柴油发动机能够在车站内和周围被隔离，同时在整个驾驶周期内将颗粒物和氮氧化物等平均排放量和燃料消耗减少高达 30%。该项目将带来多项关键的成本和脱碳效益铁路。* 通过使 DMU 在发动机关闭的情况下接近、停留和离开车站，它应促进车站内部和周围的零排放，包括氮氧化物和颗粒物* 它应实现所有排放量按比例平均减少，通过减少电能产生的燃料消耗通过辅助和牵引使用从再生制动和重新部署中恢复* 它将减少制动器磨损，从而减少刹车片的颗粒物排放，特别是车站周围的颗粒物排放* 它将通过节省燃油、发动机/变速箱维护费用来降低列车运营商的运营成本并节省刹车片* 由于加速期间动力轴数量增加，它将提高加速度并减少车轮打滑* 它不需要对现有柴油发动机或传动系统进行任何修改，并将补充任何其他脱碳举措。* 它应提供相比之下，成本和风险显着降低的解决方案与任何其他以前或当前的混合解决方案相比，导致投资回报率大大降低。该解决方案在货车应用中同样有益，可以实现显着的成本和排放节省，同时还可能提高最后一英里的平均货运速度和交通量这种创新的低成本解决方案的设计和验证所带来的商业和环境潜力，为铁路行业提供了在 5 年内改造许多传统客运车队和货运业务的机会大多数舰队。
