The need for alternative and renewable transportation fuels continues to be high on the nation's agenda. Substituting these fuels for petroleum can reduce dependence on foreign oil imports, improve air quality, and mitigate greenhouse gases. Renewable fuels offer the same advantages as...

The transportation sector is a significant contributor to current global climatic problems, one of the most prominent problems that today's society faces. In this dissertation, three complementary problems are addressed to support emissions reduction efforts by providing tools to help reduce...

Experimental investigation was carried out to study the combustion, engine performance and emission characteristics of a single cylinder, naturally aspirated, air cooled, constant speed compression ignition engine, fuelled with two modified fuel blends, B20 (Diesel–soybean biodiesel) and...

Public and private vehicle fleets have long been targeted as an ideal initial market for alternative fuel vehicles (AFVs). We examine seven widely accepted hypotheses regarding the potential fleet market for AFVs. The hypotheses are tested using data and information collected from focus group...

The effects of ethanol addition to gasoline on an SI engine performance and exhaust emissions are investigated experimentally and theoretically. In the theoretical study, a quasi-dimensional SI engine cycle model, which was firstly developed for gasoline-fueled SI engines by author, has been...

Vegetable oils pose some problems when subjected to prolonged usage in compression ignition engines because of their high viscosity and low volatility. The common problems are poor atomization, carbon deposits, ring sticking, fuel pump failure, etc. Converting the high viscosity vegetable oil...

The paper evaluates and discusses the combustion characteristics of electrolytically produced stoichiometric hydrogen-oxygen mixtures under constant volume adiabatic conditions. The results will be used in the preliminary design of a combustion chamber of a hydrogen-oxygen fuelled engine....

By synthetically combining the utilization of different fuels and the co-production of alternative fuels and power, a multifunctional energy system (MES) can present more opportunities to achieve higher efficiency, lower investment, and less environmental impact as compared to traditional energy...

Diesel engines, especially for trucks and buses, cause many economical and ecological problems. Diesel exhaust emissions are a major source of pollution in most urban centers around the world. Furthermore, the price of crude oil continues to increase rapidly. The use of alternative fuels...
