three types of vehicles, pride, peugeot 405 glx and paykan were tested from the point of view of exhaust emissions (co, hc, nox) and fuel consumption, on chassis dynamometer running european standard driving cycle with three kinds of fuels, mtbe free unleaded regular gasoline (urg) as base fuel and 10 and 15 volume percent mtbe –gasoline blends as comparable fuels. utilizing mtbe blended fuels ...

In this study two techniques, for modeling electricity consumption of the Jordanian industrial sector, are presented: (i) multivariate linear regression and (ii) neuro-fuzzy models. Electricity consumption is modeled as function of different variables such as number of establishments, number of employees, electricity tariff, prevailing fuel prices, production outputs, capacity utilizations, and...

biofuels are playing important role in recent decades as substitutes for petro diesel. biodiesel derived from vegetable oils are found to give comparable performance and emission characteristics. in this paper a comparative study has been done between two fuels combinations i.e. jatropha and castor. the biodiesel was prepared from neat oils and blends of biodiesel (up till 20%) were prepared wi...

The fuel consumption is an important component of the vehicle operating cost which is a significant component of the total transportation cost. Fuel consumption data are extensively used by transport planners, transport managers and other professional for various evaluation processes in overall gambit of sustainable transportation system. Accuracy of fuel consumption data is one of the key fact...

In the past decade, fuel consumption and CO2 emission have increased in the airline industry. Large CO2 footprint has a damaging effect on the environment. Global concerns over this issue has made the airline industry to be greener. Most efforts of the green airline industry are improving the fuel consumption to reduce the CO2 emission and its environmental damage. Here, we use cruise speed con...

A procedure for estimating fuel burned based on actual flight track data, and drag and fuel-flow models is described. The procedure consists of estimating aircraft and wind states, lift, drag and thrust. Fuel-flow for jet aircraft is determined in terms of thrust, true airspeed and altitude as prescribed by the Base of Aircraft Data fuel-flow model. This paper provides a theoretical foundation ...

The taxi-out phase of a flight accounts for a significant fraction of total fuel burn for aircraft. In addition, surface fuel burn is also a major contributor to CO2 emissions in the vicinity of airports. It is therefore desirable to have accurate estimates of fuel consumption on the ground. This paper builds a model for estimation of on-ground fuel consumption of an aircraft, given its surface...
