application of appropriate agricultural operations is a strategy to reduce energy consumption and greenhouse gas emissions from agricultural productions process. in this study, fuel consumption and greenhouse gases emissions values for each farm operation was evaluated in gorgan and ali-abad katol to soybean product. all activities and production processes about operations were monitored and re...

Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...

In order to solve energy crisis, the search for alternative fuel is extensively important. Alternative fuels selected should be renewable, sustainable and eco-friendly. In India, kerosene is also used as a fuel in cooking stove. Kerosene contains impurities like sulphur, aromatics and hydrocarbons, which causes environmental degradation. In this experimental investigation, blends of ethanol and...

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...

performances of electronic and mechanical draft control systems on a mf399 tractor were the objectives of the study to be evaluated and compared under field conditions. hence, the effects of two draft control systems (mechanical and electronic) under four ground speed levels and three set values of draft levels on rear wheel slippage, fuel consumption, compressive force within the top link and ...

The aim of this research is to study the influence of using ethanol-gasoline fuel blends on spark ignition engine performance characteristics and compare the obtained results with those using base gasoline. An electric generator operated by a SI (spark ignition, four stroke, single cylinder, air cooled) engine was used for conducting this study. The tested fuels were gasoline (E0) and gasoline-...

Traffic causes pollution and demands fuel. When it comes to vehicle traffic, intersections tend to be a main bottleneck. Traditional approaches to control traffic at intersections have not been designed to optimize any environmental criterion. Our objective is to design mechanisms for intersection control which minimize fuel consumption. This is difficult because it requires a specialized infra...

The optimal design of hybrid electric vehicle powertrains from a systems perspective is critical to realize the maximum benefits of hybridization for a given application, especially in the heavy-duty vehicle space due to the large number of unique applications. This paper proposes a novel framework that enables parametric design optimization of hybrid electric vehicles while accounting for the ...
