Abstract
Ethanol additions to the Brazilian fuel supply are seasonal and regionally variable. Thus cars in Brazil must now function with gasoline/alcohol mixtures ranging in alcohol content from 0 percent to 30 percent. A sensor system is described which measures the on-board alcohol concentration so that carburetion and/or spark timing corrections can be made for optimal engine operation.
