Microscopic urban traffic simulators embed the most detailed traveler behavior and network supply models. They represent individual vehicles and can therefore account for vehicle-specific technologies. These simulators can be coupled with instantaneous energy consumption and emissions models to yield detailed network-wide estimates of energy consumption and pollutant emissions. Nonetheless, the...

Current predictors of fuel consumption are typically based on computer simulations or data collections in real traffic, where the route and vehicle type not under researcher’s control. Here, we predicted using test track data, an approach that allowed for location-specific predictions. Ninety-one drivers drove a total 4617 laps, two vehicles (Renault Mégane, Renault Clio), routes (highway mount...

Among the alternative fuels, hydrogen shows great potential in the near future. In the present study, hydrogen utilization as diesel engine fuel was investigated. Hydrogen can not be used directly in a diesel engine due to its autoignition temperature higher than that of diesel fuel. One alternative method is to use hydrogen in enrichment or induction. To investigate the combustion characterist...

Land leveling is one of the most important steps in soil preparation and cultivation. Although land leveling with machines requires considerable amount of energy, it delivers a suitable surface slope with minimal soil deterioration as well as damage to plants and other organisms in the soil. Notwithstanding, in recent years researchers have tried to reduce fossil fuel consumption and its delete...

The aim of this work was to study the combustion, performance, and emission characteristics of a 5.5 kW four-stroke single-cylinder water-cooled direct-injection diesel engine operated with blends of biodiesel-like fuel (BLF15, BLF20 & BLF25) obtained from a 50:50 mixture of transesterified waste transformer oil (TWTO) and waste canola oil methyl esters (WCOME) with petroleum diesel. The mixtur...

This report examines the possible safety benefits from driving in a manner that results in lower fuel consumption and emissions. It attempts to assess the potential of promoting additional motivations to drive safely – better fuel economy and other environmental outcomes, and reduced running costs. Reducing speeding, lower speed limits and modifying driving style were found to improve fuel econ...

global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. nowadays, biodiesel as a renewable additive is blended with diesel fuel to achieve ...
