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.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该重大研究仪器 (MRI-R2) 奖项的目标是开发一种最先进、精确且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​​和性能的仪器。该仪器的核心是一个精确的高速静液压测功机，它吸收（或提供）来自发动机/动力传动系统的扭矩，以便发动机或动力传动系统可以遵循任何所需的转速和加速度曲线。静液压测功机用于与发动机控制系统和硬件在环车辆传动系统仿真器配合，对传动系统、车辆负载和替代动力源进行实验模拟。该仪器将允许在真实驾驶场景中测试或模拟车辆推进系统的各个方面，例如发动机、变速箱、混合动力源、储能系统、排放控制系统和传动系统，而无需实际构建完整的物理模型。作为共享的研究基础设施，该仪器将鼓励明尼苏达大学多个部门的用户进行互动和研究合作。此外，它将有助于培养下一代乐器演奏家、研究人员和工程师，以设计和建造清洁高效的汽车推进系统。开发的仪器还将被纳入本科生和研究生教育的核心机械工程课程中。它还将加强与工业合作伙伴的合作，并帮助向整个社区传播研究成果。
