The soot oxidation activity of metallic iron nanoparticles was studied under real diesel engine conditions. Particulate matter (PM) was sampled at distinct temperatures, using fuels containing ferrocene. The results indicated an 80% reduction of accumulated PM using fuels doped with 50 ppm ferrocene at a temperature of 460 ◦C. Temperature-programmed catalytic oxidation tests indicated that PM o...

Fuels based on renewable energy sources (RES) are considered as an important mean to cope with environmental problems in transport. The core objective of this paper is to investigate the perspectives of “renewable fuels” from economic, energetic and ecological points-of-view in a dynamic framework till 2050. Renewable fuels are various 1 and 2 generation biofuels as well as electricity and hydr...

The good thing about fossil fuels is that they are very energy dense, i.e., they contain a lot of energy per unit of volume. This means that fossil fuels are very good at powering cars and generating heat. The not-so-good thing about fossil fuels is that the earth has a limited amount of them. Because fossil fuels take millions of years to form, we will eventually use them up before more are ma...

Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher co...

regarding to the escalating trend of environmental pollutions, especially air pollution in great city of tehran, the perspective and study of the conditions for supply and consumption trends of fuels, with specific to fossil fuels, can lead to formation of significant figures and data. on the other hand, recognition, and if possible, reformation of environmental management schemes in the supply...
