INTRODUCTION The use of ethanol as an alternative motor fuel has been steadily increasing around the world for a number of reasons. Domestic production and use of ethanol for fuel can decrease dependence on foreign oil, reduce trade deficits, create jobs in rural areas, reduce air pollution, and reduce global climate change carbon dioxide buildup. Ethanol, unlike gasoline, is an oxygenated fuel...

porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. advanced new generation of internal combustion (ic) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. these crit...

The greenhouse effect and limitations on carbon dioxide emissions concern engine maker and the future of the internal combustion engines should go toward substantially and improved thermal efficiency engine. Homogeneous charge compression ignition (HCCI) is an alternative high-efficiency technology for combustion engines to reduce exhaust emissions and fuel consumption. However, there are still...

Description: Practical, easy–to–follow advice that saves lives Based on the author's thirty years of hands–on experience working in the field of industrial fuel systems and combustion equipment safety, this book integrates safety codes with practical, tested, and proven guidance that makes it viable to specify, operate, and maintain industrial fuel and combustion systems as safely as possible. ...

Gasoline compression ignition (GCI) has been shown as one of the advanced combustion concepts that could potentially provide a pathway to achieve cleaner and more efficient combustion engines. Fuel and air in GCI are not fully premixed compared to homogeneous charge compression ignition (HCCI), which is a completely kinetic-controlled combustion system. Therefore, the combustion phasing can be ...

We examine a simple, fuel-air, model of combustion in spark ignition (si) engine with indirect injection. In our two fluid model, variations of fuel mass burned in cycle sequences appear due to stochastic fluctuations of a fuel feed amount. We have shown that a small amplitude of these fluctuations affects considerably the stability of a combustion process strongly depending on the quality of a...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

The University of Idaho has been developing gasoline direct injection two-stroke engine technology for use in snowmobile applications as part of the Clean Snowmobile Challenge organized by the Society of Automotive Engineers. Applying GDI to a twostroke engine significantly reduces emissions of unburned hydrocarbons and improves fuel economy by reducing or eliminating the short circuiting of fu...
