This project provides a solution to substantially reduce emissions including NOx and PM when diesel passenger trains are idling.There are over 3,500 passenger rail vehicles in the UK currently fitted with a diesel engine, the large majority of these would significantly benefit from emissions reduction, especially in and around stations, where diesel engines currently continue to idle, or elevated idle whilst stationary, sometimes for up to 30 minutes at a terminal station. This is a significant contributor to local air quality issues from NOx, PM emissions etc.Furthermore, rail vehicles require large amounts of energy and power to accelerate (and therefore contributing more emissions), and yet, on the approach to stations significant amounts of energy are "lost" through "braking".This project will address both issues by recovering 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 the average emissions such as PM and NOx over a complete drive cycle by up to **35%** and operational costs by up to **30%**.Our objective is to develop and integrate a small, low mass, yet high peak torque and peak power, axle mounted motor, for retrofit and upgrade for DMU/DEMU passenger vehicle applications. This motor shall enable kinetic energy recovery during the braking application and also provide power to the trailer bogie wheels whilst accelerating.This project will enable several key cost and decarbonisation benefits to the railway.* It shall enable 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 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

该项目提供了一种解决方案，可大幅减少柴油客运列车空转时的氮氧化物和颗粒物等排放。目前英国有超过3，500辆客运铁路车辆安装了柴油发动机，其中大部分将从减排中受益匪浅，特别是在柴油发动机目前继续空转或静止时升高空转的车站及其周围，有时在终点站长达30分钟。这是NOx、PM排放等造成当地空气质量问题的重要因素。此外，轨道车辆需要大量的能量和动力来加速（因此贡献更多的排放量），然而，在接近车站时，大量的能量通过“制动”而“损失”。本项目将通过在减速过程中回收制动能量来解决这两个问题，将其用于站内辅助负载和牵引加速出站，这将使柴油机在站内和周围隔离，同时还可将整个行驶周期内的PM和NOx等平均排放量减少多达 **35%**，并将运营成本减少多达 **30%** 我们的目标是开发和集成一种小型、低质量、高峰扭矩和高峰功率高的轴装电机，用于DMU/DEMU乘用车应用的改造和升级。该电动机将在制动应用期间实现动能回收，并在加速时为拖车转向架车轮提供动力。该项目将为铁路带来几个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、停留和离开某个站点，应能够在站点内和周围实现零排放（包括NOx和PM）* 应能够按比例平均减少所有排放，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 * 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解决方案相比，它应提供成本和风险显著降低的解决方案
