Methanol as Automotive Fuel Part 1 - Straight Methanol

Abstract: A study of methanol as an automotive fuel was conducted using a single-cylinder research engine, a 4-cylinder 122-CID (2,000 cc) engine, and an 8-cylinder 350-CID engine Results showed that when using methanol as fuel, the single-cylinder engine could operate leaner than the multicylinder engines This difference is attributable to air-fuel mixture mal-distribution associated with the multicylinder engines Steady-state fuel economy and emissions data are presented and discussed Results indicate that fuel economy (on an energy input basis) using methanol fuel is about 5 percent improved as compared to gasoline fuel economy and with substantially lower nitrogen oxides emissions for methanol (ERA citation 02:026918)

Impact of Oxygenated Additives to Diesel-Biodiesel Blends in the Context of Performance and Emissions Characteristics of a CI Engine

Abstract: Butanol is receiving huge interest in the area of alternative fuel in the compression ignition (CI) engines. In this work, butanol is used as an oxygenated additive to diesel and biodiesel blend fuels to evaluate the performance and emission of CI engine. The commercially available pure diesel fuel (D100) and 80% commercially available diesel- biodiesel bled (5% biodiesel and 95% by volume) and 20% butanol (BU20) fuels were investigated to evaluate the effects of the fuel blends on the performance and exhaust emissions of a single cylinder diesel engine. The experiment was conducted at fixed load of 75% with the five engine speeds (from 1200-2400 rpm with an interval of 300 rpm). The engine performance parameters such as power, torque, fuel consumption and thermal efficiency and exhaust gas emissions such as nitrogen oxides, carbon monoxide, and exhaust gas temperature were analysed from the experimental data. The results shows that although butanol addition has caused a slight reduction in power and torque values (11.1% and 3.5%, respectively), the emission values of the engine were improved. With respect to the exhaust gas temperature, CO and NOx emissions, of BU20 is reported to have reduction by 17.7%, 20% and 3%, respectively than the B100. Therefore, butanol can be used as a fuel additive to diesel-biodiesel blends.

Formulation and method of preparation of energy fortified diesel fuel

Abstract: An energy fortified diesel fuel is provided containing a hydrocarbon additive wherein greater than 50% vaporizes at or above about 650° F. and diesel fuel of which about 90% of the diesel fuel vaporizes at or below about 640° F. or about 95% of the diesel fuel vaporizes at or below about 698° F. This energy fortified diesel fuel is made by distilling a heavy hydrocarbon fraction such as slurry oil or heavy cycle oil obtained from an FCC unit or a heavy hydrocarbon fraction obtained from a steam cracker unit at a temperature of between about 500 and 750° F. and at a pressure of between about 1 mm Hg and 10 psig to remove contaminants, removing distillate from this distillation, and mixing the distillate with diesel fuel, wherein about 90% of the diesel fuel vaporizes at or below about 640° F. or about 95% of the diesel fuel vaporizes at or below about 698° F., to form an energy fortified diesel fuel. This energy fortified diesel fuel is a desirable fuel for off highway heavy duty and "very" heavy duty compression ignition engines.

Charcoal-Oil Mixture as an Alternative Fuel: A Preliminary Study

Abstract: The fast depletion of fuel oil and continuous increase in the demand for power is a global issue. The world energy consumption is projected to grow at an average of 2.7-3.7% from 1996 to 2010. Therefore search for alternative fuel is highly prioritized. Thus this study presents the results on the characteristic of charcoal-oil mixture as an alternative fuel. The calorific value, ash content and stability of the mixture are determined.
