One of the main challenges during the development of operating strategies for modern diesel engines is the reduction of the CO₂ emissions, while complying with ever more stringent limits for the pollutant emissions. The inherent trade-off between the emissions of CO₂ and pollutants renders a...

Automotive emission is becoming a critical threat to today's human health. Many researchers are studying engine designs leading to less fuel consumption. Gearbox selection plays a key role in an engine design. In this study, Taguchi quality engineering method is employed, and optimum gear ratios...

This paper assesses using hydrogen as alternative fuel in U.S LDV (light-duty vehicle) transportation system. Firstly, the paper develops the hydrogen network model consisting of multiple production pathways that eventually lead to the FCVs (fuel-cell vehicles) for passenger transportation; such...

Recently plug-in hybrid electric vehicles (PHEVs) are emerging as one of the promising alternative to improve the sustainability of transportation energy and air quality especially in urban areas. The all-electric range in PHEV design plays a significant role in sizing of battery pack and cost....

All-electric ships are now a standard offering for energy/propulsion systems in boats. In this context, integrating fuel cells (FCs) as power sources in hybrid energy systems can be an interesting solution because of their high efficiency and low emission. The energy management strategy for...

The purpose of this article was to compare different waste heat recovery system technologies designed for automotive applications. A complete literature review is done and results in two comparative graphs. In the second part, simulation models are built and calibrated in order to assess the...
