Influence of the Addition of Alcohol Compounds to Gasoline on the Performance of a Modern Spark Ignition Engine

Abstract

The article presents the results of experimental studies of fuel efficiency and environmental indicators of an engine with a fuel injection system, feedback and a two-stage exhaust gas neutralization system running on gasoline with different content of alcohol compounds, in particular bioethanol. The study was carried out on an engine installed on a brake stand, equipped with measuring equipment, which made it possible to load the engine and determine the indicators in all possible operating modes. To assess the effect of the addition of alcohol compounds in a wide range of speed and load modes, the studies were carried out using three factorial experiments. The concentration of pollutants in the exhaust gases of the engine was determined after the neutralizer.
