Abstract

This paper reports on emissions levels for CO, NO{sub x}, and unburned fuel (UBF) from a stationary four-cylinder Chrysler engine measured under a variety of operating conditions for gasoline and three different 20 vol percent alcohol-gasoline blends. In tests of separate isobutanol, ethanol, and methanol blends, lower CO and CO{sub x} emissions were observed for the alcohol blends relative to gasoline, particularly for fuel-rich operation. Generally, on a volume (mole) basis unburned fuel emissions were highest for methanol blends and lowest for gasoline, but on a mass or OMHCE basis only small differences were noted. For a given fuel, the separate effects of engine speed, load, and equivalence ratio were examined.

Effects of ethanol and/or methanol in alcohol-gasoline blends on exhaust emissions

Journal Article Beta, R M ; Roan, V P - Journal of Engineering for Gas Turbines and Power; (USA)

The authors discuss the effect on exhaust gas emissions (carbon monoxide, CO, hydrocarbons, HC, and aldehydes, CHO) resulting from mixing methanol and/or ethanol with gasoline for automotive fuels studied experimentally. Tests were conducted on an OEM four-cylinder engine running at different conditions of equivalence ratio and spark timing. Fuel blends with different percentages of alcohol content and different ratios of methanol to ethanol in the alcohol mixture were tested. Results of this investigation indicate that the presence of either or both of the alcohols in fuel blends significantly reduced the concentration of carbon monoxide in the exhaust emissions (up tomore »« less

Performance and Regulated/Unregulated Emission Evaluation of a Spark Ignition Engine Fueled with Acetone–Butanol–Ethanol and Gasoline Blends

Journal Article Li, Yuanxu ; Ning, Zhi ; Lee, Chia-fon ; ... - Energies (Basel)

An experimental investigation was conducted on the effect of equivalence ratios and engine loads on performance and emission characteristics using acetone–butanol–ethanol (ABE) and gasoline blends. Gasoline blends with various ABE content (0 vol % to 80 vol % ABE, referred to as G100, ABE10, ABE20, ABE30, ABE60, and ABE80, respectively) were used as test fuels, where the volumetric concentration of A/B/E was 3:6:1. The experiments were conducted at engine loads of 3, 4, 5, and 6 bar brake mean effective pressure at an engine speed of 1200 rpm and under various equivalence ratios (Φ = 0.83–1.25). The results showed thatmore »« less

Experimental investigation of a DISI production engine fuelled with methanol, ethanol, butanol, and iso-stoichiometric alcohol blends

Conference Sileghem, Louis ; Ickes, Andrew ; Wallner, Thomas ; ...

Stricter CO2 and emissions regulations are pushing spark ignition engines more and more towards downsizing, enabled through direct injection and turbocharging. The advantages which come with direct injection, such as increased charge density and an elevated knock resistance, are even more pronounced when using low carbon number alcohols instead of gasoline. This is mainly due to the higher heat of vaporization and the lower air-to-fuel ratio of light alcohols such as methanol, ethanol and butanol. These alcohols are also attractive alternatives to gasoline because they can be produced from renewable resources. Because they are liquid, they can be easily storedmore »« less

Ethanol and methanol blends with gasoline: an experimental approach to engine performance and emissions

Thesis/Dissertation Bata, R M

The effect of mixing methanol and/or ethanol with gasoline in fuel blends on brake specific fuel consumption, brake specific energy consumption, and exhaust gas emissions (CO, HC, CHO) was studied. Tests were conducted on an OEM 4-cylinder engine running at different conditions of equivalence ratio, spark timing, percent of alcohol in alcohol-gasoline blends, and mixture of methanol and ethanol in the fuel. Results indicated that fuel consumption increased as the percentage of alcohol was increased above 5% in an alcohol-gasoline blend. Fuel consumption also increased by 2 to 5% with retarded spark timings. Brake specific energy consumption was found tomore »« less
