Engine performance and exhaust emissions: methanol versus isooctane

Abstract: Operating characteristics of a single-cylinder, spark-ignition engine fueled by both methanol and isooctane were determined. Engine output, indicated specific fuel consumption, and specific emissions of hydrocarbon, carbon monoxide, nitric oxide, and aldehydes were measured for both fuels and compared using the performance maps. The engine output comparisons showed that lean misfire limits occurred at leaner mixtures with methanol than with isooctane and that maximum engine output levels were nearly equal for both fuels. Comparison of the specific parameters of each fuel at equivalent power levels obtained with maximum power spark timing permits the following conclusions: use of methanol results in higher indicated specific fuel consumption, greater emission of aldehydes, but lower emissions of hydrocarbon and nitric oxide; the two fuels showed similar trends of carbon monoxide emission.

Fuel additive and method for improving combustion

Abstract: A fuel additive for addition in a vapor phase to a fuel such as gasoline in the air/fuel mixing zone of an internal combustion engine for increasing combustion efficiency in the engine while reducing the amount of gaseous pollutant emissions.

Fuel for engines

Abstract: Nitroparaffins are added to gasoline together with synthetic lubricants of the ester type (e.g. synthetic jet turbine oil) and are used as fuel in glow engines, jet engines and internal combustion engines in general to improve combustion efficiency, especially by lowering fuel consumption while increasing the output and providing cleaner burning.

Utilization of synthetic fuels other than hydrogen

Abstract: This report reviews the utilization aspects of several synthetic fuels in the areas of transportation; commercial, residential, and industrial use; and electricity generation. Fuels such as ammonia (NH/sub 3/), hydrazine (N/sub 2/H/sub 4/), methanol (CH/sub 3/OH), and ethanol (C/sub 2/H/sub 5/OH) can be readily synthesized and are therefore discussed here. Another category of fuels, which would be recycled in the oxidized form to the generating station, is the metals. The only reasonable way to consider a metal fuel seems to be as an electrochemical fuel; in this study, rechargeable batteries are, therefore, given brief consideration. 24 references, 5 figures, 5 tables.
