TL;DR: In this paper, the effect of mixing methanol and/or ethanol with gasoline for automotive fuels was studied experimentally, and the results indicated 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 to 40-50 percent compared to pure gasoline only).
Abstract: 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 to 40-50 percent compared to pure gasoline only), with methanol slightly more effective than ethanol. Hydrocarbon emissions were also decreased by increasing the alcohol content of the fuel, with minimum hydrocarbon production occurring at percent alcohol-gasoline blends in conjunction with near-stoichiometric air-fuel ratios. However, aldehyde emissions were found to be markedly higher with alcohol-gasoline blends. The 10 percent alcohol-gasoline blends were found to produce about 50 percent more aldehyde emissions than pure gasoline.

TL;DR: In this article, a control unit coupled with the alcohol concentration sensor and the oxygen sensor is used to calculate a basic value for the amount of fuel metered to the engine based on engine operating conditions and corrects the sensed alcohol concentration.
Abstract: An apparatus for use with an internal combustion engine operable on either of gasoline fuel and gasoline/alcohol fuel blend. The apparatus comprises an alcohol concentration sensor for sensing the alcohol concentration of the fuel to be delivered to the engine, an oxygen sensor sensitive to the oxygen content of exhaust gases discharged from the engine for producing an air/fuel ratio feedback signal, and a control unit coupled to the alcohol concentration sensor and the oxygen sensor for controlling the amount of fuel metered to the engine. The control unit calculates a basic value for the amount of fuel metered to the engine based on engine operating conditions and corrects the calculated basic value for the sensed alcohol concentration. A correction factor, which is set within a control range defined by predetermined upper and lower limits, is calculated based on a deviation of the air/fuel ratio from a stoichiometric value. The calculated basic value is corrected based on the calculated correction factor to provide a closed loop air/fuel ratio control. The upper and lower limits are changed to expand the control range in the presence of an alcohol concentration signal change exceeding a predetermined degree.
