This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The objective of this Major Research Instrumentation (MRI-R2) award is to develop a state-of-the-art, precise and highly flexible instrument for testing and measuring the fuel efficiency, emissions and performance of automotive propulsion systems. The centerpiece of the instrument is a precise and high-speed hydrostatic dynamometer, which absorbs (or provides) torques from (or to) the engine/powertrain so that the engine or powertrain can follow any desired rotational speed and acceleration profile. The hydrostatic dynamometer is utilized to experimentally mimic the drive train, vehicle load, and the alternative power sources in coordination with an engine control system and a hardware-in-the-loop vehicle driveline emulator. This instrument will allow all aspects of the vehicle propulsion system such as the engine, transmission, hybrid power sources, energy storage systems, emission control systems and driveline system to be tested or simulated in a real-world driving scenario without actually building the complete physical system.As a shared research infrastructure, the instrument will encourage the interaction and research collaboration of users from multiple departments at the University of Minnesota. Furthermore, it will help to prepare the next generation instrumentalists, researchers and engineers to design and build clean and efficient automotive propulsion systems. The developed instrument will also be integrated into core mechanical engineering curriculum for both undergraduate and graduate education. It will also enhance collaborations with industrial partners and help to disseminate research results to communities at large.

该奖项由2009年《美国复苏和再投资法案》(公法111-5)资助。该重大研究仪器(MRI-R2)奖项的目标是开发一种最先进、精确和高度灵活的仪器，用于测试和测量汽车推进系统的燃油效率、排放和性能。该仪器的核心是一个精密的高速静液压测功机，它吸收(或提供)发动机/动力总成的扭矩，使发动机或动力总成可以遵循任何所需的转速和加速曲线。利用液压测功机与发动机控制系统和车辆传动系半实物仿真器相配合，对传动系、车辆负载和替代动力源进行实验模拟。该仪器将允许车辆推进系统的所有方面，如发动机、变速器、混合动力源、储能系统、排放控制系统和传动系统在真实世界的驾驶场景中进行测试或模拟，而无需实际构建完整的物理系统。作为一个共享的研究基础设施，该仪器将鼓励来自明尼苏达大学多个系的用户之间的互动和研究合作。此外，它还将有助于培养下一代仪表师、研究人员和工程师，以设计和制造清洁高效的汽车推进系统。开发的仪器还将被整合到本科和研究生教育的核心机械工程课程中。它还将加强与工业伙伴的合作，并帮助向广大社区传播研究成果。
