**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 ** 该项目解决了特定的竞赛主题，作为一种技术解决方案，可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，同时在站内提供潜在的零排放和显著的运营成本效益。该技术不需要对现有发动机、变速器或主减速器进行任何修改，允许在减速期间回收制动能量，并将其重新用于站内辅助负载和牵引，以加速出站。这将使柴油发动机能够在车站内和周围隔离，同时还可以在整个驱动周期内将PM和NOx等平均排放量以及燃油消耗量减少多达30%。该项目将为铁路带来几项关键的成本和脱碳效益。*通过使DMU能够在发动机关闭的情况下接近、停留和离开车站，应有助于车站内和周围的零排放，包括NOx和PM。通过从再生制动中回收电能并通过辅助和牵引使用进行重新部署，从而降低燃料消耗 * 它应能减少制动器磨损，从而减少制动片的颗粒排放，特别是在车站周围。它应能通过节省燃料降低列车运营商的运营成本，节省发动机/变速箱维护和制动片 * 由于在加速过程中增加了动力轴的数量，它应提供增加的加速度和减少的车轮滑移 * 它不需要对现有的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计划。与任何其他先前或当前的混合动力解决方案相比，该解决方案将提供显著更低的成本和风险，从而大大降低ROI。该解决方案在货车应用中同样有益，从而可以实现显著的成本和排放节省，同时还可能提供增加的平均货运速度和交通量，最后一英里操作，增加的加速度，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年内改造大多数车队的许多传统客运车队和货运运营的机会。
