Developing a new technology requires decisionmakers to understand the technology’s implications on an organization’s objectives, which depend on user needs targeted by the technology. If these needs are common between two organizations, collaboration could result in more efficient technology development. For hybrid truck design, both commercial manufacturers and the military have similar perfor...

The US coal mining industry consumes approximately 142 billion kWh per year of energy. The US Department of Energy estimates that the industry‟s annual energy consumption can be reduced by 49% (24.6 billion kWh/year by using currently available best practices and a further 44.8 billion kWh/year with more research). This constitutes nearly $3.7 billion of potential savings on coal production cos...

Aerodynamics of trucks and other high sided vehicles is of significant interest in reducing road side accidents due to wind loading and in improving fuel economy. Recognizing the limitations of conventional wind tunnel testing, considerable efforts have been invested in the last decade to study vehicle aerodynamics computationally. In this paper, a three-dimensional near field flow analysis has...

The feasibility of several alternatives to long-haul truck idling are investigated. Battery Powered systems (BPS) where batteries are charged off the alternator is considered. Moreover, BPSs with various battery types are compared to determine which one would have the greatest impact on the fuel consumption and overall performance. In addition, applicability of thermal energy storage (TES) is s...

We study a cross-dock operator’s truck scheduling problem at inbound doors in case of unknown truck arrival times. Due to uncertainty of truck arrivals, a scheduling strategy is subject to variations in costs of serving the trucks. A cost-stable scheduling strategy is defined as a schedule with low variation levels. In this paper, we analyze the cross-dock operator’s problem of determining a co...

Nowadays the demand for reducing pollutant emissions and fuel consumption have paved the way of developing more fuel-efficient power generation system for transportation sector. Micro gas turbine (MGT) system can be an alternative to internal combustion reciprocating engine due to its light-weight and less fuel consumption. In this paper, some major running and operating characteristics of MGT ...

The recent release of hydrogen economy roadmaps for several major countries emphasizes the need accelerated worldwide investment in research and development activities production, storage, infrastructure utilization transportation, industry electrical grid. Due to high gravimetric energy density hydrogen, focus technologies that utilize this fuel has recently shifted from light-duty automotive ...

On-road vehicle tests of three diesel trucks were conducted by a portable emission measurement system (PEMS) in Chengdu, China. SEMTECH-ECOSTAR provided by Sensors, Inc and MI2, an emissions measuring instrument powered by the Pegasor Particulate Sensor (PPS) were employed to detect gaseous and particle emissions during the tests. The impacts of speed and acceleration on emissions were analyzed...

This paper formulates a mathematical model for the Green Vehicle Routing Problem (GVRP), incorporating bi-fuel (natural gas and gasoline) pickup trucks in a mixed vehicle fleet. The objective is to minimize overall costs relating to service (earliness and tardiness), transportation (fixed, variable and fuel), and carbon emissions. To reflect a real-world situation, the study considers: (1) a co...

Fuel consumption for heavy trucks depends on many factors like roads, weather, and driver behavior that are hard for a manufacturer to influence. However, one design possibility is the powertrain configuration. Here a new simulation program for heavy trucks is created to find the configuration of the powertrain that gives the lowest fuel consumption for each transport task. For efficient simula...
