Training / Education Classroom Seminars
Developing vehicles that achieve optimum fuel economy and acceleration performance is critical to the success of any automotive company, yet many practicing engineers have not received formal training on the broad range of factors which influence vehicle performance. This seminar provides this fundamental understanding through the development of mathematical models that describe the relevant physics and through the hands-on application of automotive test equipment. Attendees will also be introduced to software used to predict vehicle performance.

Abstract Success of the vehicle in cold countries depends on performance of the vehicle under cold climatic conditions. In automobiles, structural elastomer components have strong influence on vehicle performance including NVH, ride comfort & durability. Elastomers are sensitive in nature to these climatic conditions due to its temperature dependent visco-elastic behavior. Thus, it is very important to understand structural elastomer component's performance at sub zero temperatures. In a vehicle, Engine mount is used to hold engine firmly and isolate vibrations away from chassis. Vibration isolation of a mount at low temperature is generally affected by the rubber composition. Major ingredients of the rubber composition influencing the low temperature characteristics are Elastomer type, filler type, plasticizer and curing system. Rubber composition plays key role in achieving engine mount properties like static stiffness, dynamic stiffness, permanent set and durability.

Abstract The Hybrid Electric Vehicle Team (HEVT) of Virginia Tech is ready to compete in the Year 3 Final Competition for EcoCAR 2: Plugging into the Future. The team is confident in the reliability of their vehicle, and expects to finish among the top schools at Final Competition. During Year 3, the team refined the vehicle while following the EcoCAR 2 Vehicle Development Process (VDP). Many refinements came about in Year 3 such as the implementation of a new rear subframe, the safety analysis of the high voltage (HV) bus, and the integration of Charge Sustaining (CS) control code. HEVT's vehicle architecture is an E85 Series-Parallel Plug-In Hybrid Electric Vehicle (PHEV), which has many strengths and weaknesses. The primary strength is the pure EV mode and Series mode, which extend the range of the vehicle and reduce Petroleum Energy Usage (PEU) and Greenhouse Gas (GHG) emissions.

For most Heavy Duty (HD) diesel engines over 50% of total fuel energy is lost to the ambient as heat (exhaust and coolant). Eaton Roots (Supercharger) technology has been used as expander (Roots Expander to demonstrate an efficient Organic Rankine Cycle (ORC) Waste Heat Recovery (WHR) system for a HD diesel engine. The present work includes a baseline engine characterization to identify and quantify the potential waste energy sources and correlate the thermodynamic models. Thermodynamic models were used to assess the merits of various WHR layouts and WHR components on system performance. An average of 6% fuel economy improvement has been predicted for Eaton Supercharger based expander in an ORC WHR system with ethanol as a working fluid for HD diesel engines

As part of its efforts to reduce the consumption of petroleum fuels at a national level, the US Department of Energy awarded several contracts to improve Class 8 truck freight hauling efficiency (ton-miles/gal) by greater than 50%. The class tuck segment was targeted because of the large amount of fuel consumed by these vehicles. To reach this aggressive target, all elements of the vehicle and power train were studied to determine the most customer centric elements to incorporate into the truck. A key enabler to meet the freight efficiency improvement was developing and integrating technology to improve diesel engine fuel energy conversion efficiency by 20% to achieve a brake thermal efficiency of 50%.

Commercial vehicles and off-road equipment provide functions that are key for sustainable economic growth. They are crucial for long haul movement of goods, they provide for services and infrastructure support, they are used for local delivery and people movement as well as to move soil, harvest bio-mass to provide food, and provide the power needed for construction, mining and other resource management efforts. Owing to the significant amount of fuel consumed by the market segment, the US has implemented CO2 and Fuel Economy regulations for Commercial On-Highway engines and vehicles, driven by both environmental concerns and the desire for energy independence. Many other regions are also considering or developing analogous regulations. While improvements to their fuel efficiency are implemented, these engines must also comply with all criteria pollutant emission and be in balance with the business needs of the purchaser and operator.

Oak Ridge National Laboratory’s Vehicle Systems Integration powertrain test cell is designed to develop and test medium and heavy-duty vehicle hybrid powertrains by subjecting them to steady state and transient operating speeds and loads representative of real world driving conditions. This facility is currently supporting the development of heavy-duty emissions and fuel consumption test procedures. Three different types of power-packs (automated manual, automatic, and hybrid transmissions coupled to the same heavy-duty engine) are being subjected to an extensive matrix of tests and drive cycles using a powertrain-in-the-loop set-up. This presentation will compare engine-only results, power-pack results, as well as chassis dynamometer results to establish the advantages and disadvantages of each testing method.

Building upon the success of the first-ever U.S. regulatory program to reduce greenhouse gas emissions (GHG) and improve the fuel efficiency of medium- and heavy-duty vehicles, issued in 2011, the Environmental Protection Agency (EPA), the National Highway Traffic Safety Administration (NHTSA), and California Air Resource Board (CARB) are working together to develop the technical foundation for proposing the next phase of heavy-duty GHG and fuel efficiency standards. One of the options the Agencies are considering involves recognizing the efficiency of powertrain technologies within the context of a full vehicle standard. For this option it becomes critical to develop methods that assess the expected real world performance of those technologies, which include the engine, transmission, and axle technologies. In order to accomplish this goal, the agencies have developed and evaluated a number of experimental approaches to recognize the performance of these technologies.

WIP Standard
J2188
This SAE Recommended Practice takes into account modern standardized methods for collecting and summarizing data that has an effect on vehicle steady-state performance, such as engine output (gross and net), transmission losses, drivetrain efficiency, vehicle aerodynamic devices for various vehicle and body configurations, as well as road surface variations and air density variations resulting from altitude and barometric effects. The procedure does not address vehicle transient performance (acceleration, braking, and cornering), because of the considerable amount of additional data required such as moment of inertia of all the rotating parts. Nor does it address vehicles with torque converters and automatic transmissions. This document is, therefore, intended for vehicles having fixed-ratio type transmissions and positive engagement clutches. Metric and ISO unit conversions are provided in the metric conversion tables at the end of this procedure (see Appendix B).
