Scientists at the University of Minnesota (UM), Twin Cities, are developing a precise and highly flexible rapid-prototyping research platform to test and measure the fuel efficiency, emissions and performance of hybrid vehicles. The platform's centerpiece, a hydrostatic dynamometer, mimics the drive train, vehicle load and alternative power sources so that researchers can measure any rotational speed or acceleration profile.

Because the platform simulates real-world driving conditions, it will allow researchers to test all components of the vehicle propulsion system without actually building a complete physical hybrid engine. This will allow researchers to optimize performance without incurring high production costs.

Power-train hybridization is one of the most promising approaches for reducing vehicle fuel consumption and emissions. Various hybrid vehicle concepts have been proposed. At their most basic, they involve combining an alternative power source and an internal combustion engine. Hybrid design must coordinate the operation of each source to optimize the efficiency of the overall system.

The shared instrument will encourage the interaction and research collaboration of users from multiple departments at UM. It will also help to prepare the next-generation instrumentalists, researchers and engineers in designing and building clean and efficient automotive propulsion systems.
