Dana’s New Exhaust Gas Heat Recovery Technology Improve Emissions and Fuel Savings
At the IAA Commercial Vehicles 2014, Dana Holding Corpo- ration presented its Long brand exhaust gas heat recovery (EGHR) technology, which enables vehicle manufacturers to improve fuel economy by up to 3 per cent.
As the commercial vehicle industry remains focused on addressing global fuel efficiency and emissions regulations, Dana’s new technol- ogy enables customers to reduce friction in the engine, transmission, and axle by redirecting exhaust heat to rapidly warm powertrain fluids during cold start and ramp up. The result is higher fuel efficiency and reduced overall emissions.
“Today’s standard combustion-engine powertrains need to be cleaner and more efficient, and the heat and pollutants ejected through a ve- hicle’s exhaust compromise its efficiency,” said Dwayne Matthews, President of the Dana Power Technologies Group. “Dana’s EGHR technology applies our expertise in heating and cooling technologies to provide a cost-effective solution for our customers looking to im- prove energy usage and fuel economy, while reducing weight and complexity.”
Dana’s EGHR solution is more compact and up to 50 per cent lighter than competing devices, enabling it to be installed immediately down- stream of the catalyst to capture the gas at a higher temperature. When coupled with Dana’s Long active warm-up units, the system is able to significantly reduce the time it takes to achieve optimum oper- ating temperatures in the powertrain.
For more than a century, Dana’s thermal-management engineers have designed innovative heat exchangers. This EGHR solution is the latest in a line-up of technologies that focuses on optimising operating tem- peratures in the vehicle by utilising otherwise wasted heat and directing it back to the powertrain and the cabin to improve warm-up times.
Dana新排气热能回收技术 改善废气排放和节油
在2014年汉诺威商用车展，Dana控股公司展示了 它旗下的Long品牌排气热能回收技术(EGHR) ，并宣称可协助汽车制造商改善高达3%的燃油
经济。
当商用车行业持续聚焦于应付全球燃油效率和废气排放 的法令，Dana的新技术通过在冷启动和升温时，改变排 气的热能方向，并将之导向快速变暖的动力传动系统流 体，使客户能够降低引擎、传动系统及车轴的摩擦。结 果是更高的燃油效力和降低整体排放。
“今天的内燃机动力传动系统需要更干净和更有效率， 然而所排出的热气和污染物却影响了它的效率。”Dana 电源技术集团总裁马修斯 (Dwayne Matthews)表 示。“Dana排气热能回收技术应用我们在加热和冷却方 面的专门知识，在降低重量和复杂性的同时，为正在寻 求改善能源使用和燃油经济的客户提供一个具成本效益 的解决方案。 ”
Dana排气热能回收解决方案更为精巧，而且比其他的竞 争装置便宜了50%，使它能够马上安装于催化剂下游的 废气管中，以便在更高的温度下猎取排气。配合Dana的 Long主动加热单位，该系统能够大大降低它在动力传动 系统中达到优化温度的时间。
Dana温度管理工程师设计创新热能交换器超过一个世 纪。该排气热能解决方案是聚焦于优化车子运作时间的 最新技术系列，将废气热能重新导入动力传动系统和驾
