Study of natural gas vehicles (NGV) during the fast fill process
Natural gas is being used as an alternative fuel to gasoline. Natural gas vehicle (NGV) refueling stations, however, are not able to guarantee a 100% full fill to NGV's. A system was designed and built to better understand the characteristics of CNG during the fill process. Useful characteristics …

A heat transfer model applicable to the refuelling process for natural gas vehicles
… between a storage cylinder and the incoming gas during the cylinder charging process. A theoretical model of convective heat transfer between the gas and the cylinder is described. Experiments with the high pressure gas (AP=14.5-16.5MPa) charging process to a vehicle supply tank were carried …

Preparation, Evaluation and Structural Modeling of Carbon-Based Adsorbents Used on Natural Gas Vehicles
… large surface areas and strong ability to adsorb gases and liquids. In this study, activated carbons are prepared from low cost materials, and their application in natural gas storage is investigated. Micropore volume and bulk density of carbon adsorbents are found to be the most important factors …

Economic implications of natural gas vehicle technology in U.S. private automobile transportation
… imported. With significant domestic conventional gas resources, optimistic projections of unconventional natural gas resources, and the growing international liquefied natural gas (LNG) market, gas prices are expected to remain lower than oil. While natural gas currently provides approximately 24 …

Three Essays in Empirical Economics
… essay estimates a demand function for compressed natural gas as a fuel substitute to diesel fuel for firms with hybrid fleets. The data is from the Energy Information Administration, for the years 1989 to 2009, for 47 states. Results show that an increase of $0.10 in the price of diesel fuel will …
