Axle mounted motor for retrofit to DMU's to enable zero emissions in stations

该项目为柴油客运列车空转时大幅减少氮氧化物和颗粒物排放提供了解决方案。目前，英国有超过3500辆客运铁路车辆配备了柴油发动机，其中大部分将从减排中显著受益，特别是在车站及其周围，柴油发动机目前继续闲置，或在静止时升高闲置，有时在终点站长达30分钟。此外，铁路车辆需要大量的能量和动力来加速（因此会产生更多的排放），然而，在到达车站的途中，大量的能量通过“刹车”“损失”了。该项目将通过在减速过程中回收制动能量并将其重新用于车站辅助负载和牵引以加速出站来解决这两个问题，这将使柴油发动机在车站内外被隔离，同时在整个驱动周期内减少PM和NOx等平均排放量高达**35%**，运营成本高达**30%** ** ** *。我们的目标是开发和集成一种小、低质量、高峰值扭矩和峰值功率的轴装电机，用于DMU/DEMU乘用车的改造和升级。该电机应在制动过程中实现动能回收，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能够在关闭发动机的情况下接近、停留和离开车站，使车站内及周围实现零排放，包括氮氧化物和PM。*它应使所有排放按比例平均减少。通过辅助和牵引使用再生制动和重新部署的电能回收减少燃料消耗*它将减少制动磨损，从而减少刹车片的颗粒排放，特别是在车站周围*它将通过节省燃料来降低火车操作员的运营成本。*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举措。*与以往或目前的任何混合解决方案相比，它应提供成本和风险大大降低的解决方案

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
