项目摘要

The internal combustion engine which is in everyday use in a wide variety of applications remains one of the most cost effective means of generating power. A typical engine however loses substantial amounts of energy in its normal operation and there is clear potential to utilise this energy. The largest flow is in the exhaust system of the vehicle, and it is here that the proposed research is focussed. The main objective of the project is the realisation of an efficient method of energy recovery using a thermoelectric generator and utilising a new type of material known as a skutterudite. By adopting the same internal structure, skutterudites simulate a naturally occurring mineral which has the vital properties of low thermal conductivity with low electrical resistance. The principal advantage of these materials is their potential for cost reduction by utilising low cost metals in their structure. A second and important advantage is the future potential for novel manufacturing techniques in which the active elements of the thermoelectric generator are made using additive methods to build up the kind of complex shapes that are required. The project brings together three universities that can cover the range of capabilities from the chemistry of materials through to systems integration methods. The Heriot-Watt team will synthesise new materials using progressively lower cost materials to demonstrate that the required thermoelectric performance can be obtained using low cost materials. The Cardiff team will integrate modules, incorporating protective coatings to ensure the durability of the generator. At Loughborough, the scope to integrate thermo-electric (TE) generators with other functions such as after-treatment will be explored. The Loughborough team will work with the Cardiff team to identify novel methods of integrating the TE modules into a heat exchange device, regarding the requirements imposed by different types of engine. The project concludes with the practical demonstration of TE generators and a portfolio of simulation results that demonstrate how the cost path and the path to levels of commercial performance will be realised.

在各种应用中日常使用的内燃机仍然是最具成本效益的发电手段之一。然而，典型的发动机在其正常操作中损失大量的能量，并且存在利用该能量的明显潜力。最大的流量在车辆的排气系统中，并且这里是所提出的研究的重点。该项目的主要目标是利用热电发电机和一种称为方钴矿的新型材料实现一种有效的能量回收方法。通过采用相同的内部结构，方钴矿模拟了一种天然存在的矿物，其具有低热导率和低电阻的重要特性。这些材料的主要优点是通过在其结构中使用低成本金属来降低成本的潜力。第二个也是重要的优点是新型制造技术的未来潜力，其中热电发电机的有源元件是使用添加剂方法制造的，以建立所需的复杂形状。该项目汇集了三所大学，可以涵盖从材料化学到系统集成方法的能力范围。Heriot-Watt团队将使用成本逐渐降低的材料合成新材料，以证明使用低成本材料可以获得所需的热电性能。卡迪夫团队将整合模块，包括保护涂层，以确保发电机的耐用性。在拉夫堡，将探索将热电（TE）发电机与后处理等其他功能集成的范围。拉夫堡团队将与卡迪夫团队合作，根据不同类型发动机的要求，确定将TE模块集成到热交换设备中的新方法。该项目的最后是TE发电机的实际演示和一系列模拟结果，这些结果展示了如何实现成本路径和商业性能水平。
