Book Description
The aim of this study is to develop the one-dimensional model of a four-cylinder, four-stroke, multi-point injection system SI engine and a direct injection system SI engine for predicting the effect of various fuel types on engine performances, specific fuel consumption, and emissions. Commercial software AVL BOOST was used to examine the engine characteristics for different blends of methanol and gasoline (by volume: 5% methanol [M5], 10% methanol [M10], 20% methanol [M20], 30% methanol [M30], and 50% methanol [M50]). The methanol-gasoline fuel blend results were compared to those of net gasoline fuel. The obtained results show that when methanol-gasoline fuel blends were used, engine performance such as power and torque increases and the brake-specific fuel consumption increases with increasing methanol percentage in the blended fuel.

Book Description
This monograph focuses on methanol and its utilization in transportation sector, namely in spark ignition (SI) engines. The contents focus on methanol production and presents a variety of production technologies from different feedstocks. The potential of methanol utilization in transportation in SI engines is discussed, its challenges, limitations, aspects related to its utilization and current global use of methanol are also presented. The book also contains chapters related to pollutant formation and exhaust emissions from methanol fuelled SI engines, one chapter is focused specifically on formaldehyde emissions, which possesses one of the greatest challenges of methanol use in IC engines. Readers will learn about the production aspects of methanol, its potential as a sustainable fuel, its utilization in SI engine and the effect of methanol and its utilization techniques on engine performance, combustion, exhaust emissions, efficiency and other important parameters. This volume will be a useful guide for professionals, post-graduate students involved in alternative fuels, spark ignition engines, and environmental research.

Book Description
During the last years, concerns regarding climate change, decline of energy security, and hydrocarbon reserves have resulted in a wide interest in renewable alternative sources for transportation fuels. Methanol and ethanol have been possible candidates as alternative fuels for the internal combustion engines because they are liquid and have several physical and combustion properties which resemble those of gasoline. Therefore, the aim of this study is to develop the one-dimensional model of a gasoline engine for predicting the effect of various fuel types on engine performances, specific fuel consumption, and emissions. Commercial software AVL BOOST was used to examine the engine characteristics for different blends of methanol, ethanol, and gasoline (by volume). A comparison was made between the results gained from the engine simulation of different fuel blends and those of gasoline. They show that when blended fuel was used, the engine brake power decreased and the BSFC increased compared to those of gasoline fuel. When blended fuel increases, the CO and HC emissions decrease, and there is a major increase in NOx emissions when blended fuel increases up to 30% M30 (E30). Increase in the percentage of ethanol and methanol leads to a significant increase in NOx emissions.

Book Description
An 18-month field test was conducted to determine if the Virginia Department of Highways & Transportation should give serious consideration to the use of methanol as a substitute for gasoline in the operation of its motor vehicles. Five of the eight 1973 and 1974 model vehicles involved in the test were operated for a total of 92,000 miles on a fuel blend containing an average of 10.7% methanol and 89.3% lead-free gasoline. The fuel was dispensed from a commercial type gasoline blending pump by blending at the nozzle and by pumping directly from a storage tank containing a specified blend of methanol and gasoline. The vehicles operating on the blend averaged 4.0% fewer miles per gallon but were 1.3% more efficient from a miles/Btu standpoint than the vehicles operating on lead-free gasoline. Exhaust emissions data suggested that emissions are more dependent on carburetor adjustments than on the percentage of methanol in the fuel. Drivability was impaired enough in two of the vehicles operating on the blend to warrant carburetor modifications before the vehicles could be operated safely and satisfactorily because the addition of methanol made the fuel air mixture too lean for good engine performance and because the methanol was incompatible with certain fuel system parts. Since methanol and gasoline are not completely miscible at all temperatures and moisture conditions, a major effort was required to properly store and dispense the desired blend. From a consideration of economic and supply factors, it was concluded that the use of methanol-gasoline blends in Department vehicles would not be justified at this time. Implementation would require that special attention be directed to vehicular adjustments and to the storage and handling of the blends.

Book Description
This monograph is based on methanol as a fuel for transportation sector, specifically for compression ignition (CI) engines. The contents present examples of utilization of methanol as a fuel for CI engines in different modes of transportation such as railroad, personal vehicles or heavy duty road transportation. The book also focuses on effect of methanol on combustion and performance characteristics of the engine. The effect of methanol on exhaust emission production, prediction and control is also discussed. It also discusses current methanol utilization and its potential, its effect on the engine in terms of efficiency, combustion, performance, pollutants formation and prediction. Part of the chapters are based on review of state-of-the-art while other chapters are dedicated to an original research. This volume will be a useful guide to professionals and academics involved in alternative fuels, compression ignition engines, and environmental research.

Book Description
Amongst concerns about climate change, energy security decline and depletion of fossil fuels, this book explores the high importance of and interests in alternative energy resources. Many studies have shown that biomass fuels are sustainable, environmentally friendly and can be the most appropriate replacement to the depleting crude oil. Additionally, they can expand green landscapes, create new job opportunities, be directly utilised in standard power systems and improve combustion performance. Biomass fuels can be limited due to production cost and competition with food. Therefore, plant and food wastes play an important role in reducing these costs and recycling dump bio-materials. Production of biofuels from non-food biomass has emerged as a sustainable option to tackle the problems associated with growing demands for energy.
