Hugh Blaxill. Managing Director MAHLE Powertrain LLC. Novi, Michigan

Hugh Blaxill is currently Managing Director of MAHLE Powertrain LLC based in Novi, Michigan. MAHLE Powertrain is an engineering consultancy working in the automotive and aerospace fields under the ownership of MAHLE, the well known tier 1 component supplier. Hugh leads a team of specialized engineers in design, development, calibration, controls and diagnostic tools. Hugh was previously Chief Engineer for Research and Development at MAHLE Powertrain (and previously Cosworth) in the UK working on many IC engine research topics such as; downsizing, range extenders, advanced combustion concepts and hardware solutions. Prior to that he worked on a number of production engine development projects for many of the major OEM’s globally. Hugh joined MAHLE from Ricardo where he worked on production diesel engine development. He completed his two degrees at The University of Bath, in the UK.

Topic: Turbulent Jet Ignition: An efficient, clean combustion concept for the future?

In order to meet future global emissions goals, in the short to medium term it will be necessary to continue to improve the fuel consumption of the spark ignited gasoline engine. Gasoline engine downsizing is the dominant technology being implemented in the US and globally. In addition technologies such as variable valvetrains and stratified lean combustion have been implemented by some manufacturers. This presentation considers the application of a homogenous ultra lean combustion system to current and future engine technologies. The ultra lean combustion system is achieved via a high energy Turbulent Jet Ignition system. Turbulent Jet Ignition is an advanced spark initiated prechamber combustion system. The ultra lean combustion system has been shown to achieve high thermal efficiencies and low NOx emissions. Furthermore the improved knock resistance of the system allows, due to the distributed ignition sites, improvements in the compression ratio or a synergy with boosted applications.

Mark R. Vaugh, Research Professor, Mechanical Engineering – Engineering Mechanics Michigan Technological University

Mark Vaughn holds a PhD in mechanical engineering and an MS in biomedical engineering from The University of Texas at Austin as well as a BS in biomedical engineering from the University of New Mexico. He began his career at the
Center for Electromechanics in Austin designing and building pulsed power flywheel inertial energy storage systems and railguns for SDI. This work required him to invent new hydrostatic bearing technology. Mark worked for over 26 years at Sandia National Laboratories in Albuquerque New Mexico. He spent four years working in advanced nuclear weapon use control systems. He then worked building one-of-a-kind missile payloads for the next ten years, primarily for SDI. During this time he began work in medical devices including prosthetics, wound healing, and wheelchair assistive devices. A robot project took him to the robotics department for four years, where he worked on a variety of DARPA projects. After doing design and development work for earth penetrators, he worked for several years in the Synthetic Aperture Radar (SAR) gimbal group on heat removal and bearing tasks while also starting up a UAV payload effort. Finally, he followed a DARPA drilling project to the geothermal group, where he also collaborated on a study of energy storage for microgrids. He holds ten US patents.

Topic: Energy Storage for Power Grid Integration of Renewables

Renewable energy sources, solar, wind, etc, are becoming a larger proportion of overall electrical energy production. In order to improve the utilization efficiency of these new sources in the existing power grid, energy storage will be needed. Numerous energy storage modalities are examined, with commentary on advantages and disadvantages of each. Selection strategies will be discussed.
