Traffic emission control through gasoline automotive engine mixture enhancement

Abstract

Transportation networks today are witnessing a dramatic increase in traffic volume that emits large amounts of pollutants into the atmosphere. Many environment‐friendly technologies are introduced recently to reduce vehicles' emissions. It is possible to obtain a homogeneous fuel–air mixture in the internal combustion engines under ideal conditions, but it is hard to have control on this mixture in the abnormal conditions. Based on the engine's working conditions, the mixture, sometimes, becomes rich and at other times it might become chemically correct. In this work, a new spiral shape device is used to enhance the mixture homogeneity and to maintain a correct fuel–air mixture. The spiral device works on enhancing the mixture through dividing the fuel particles into smaller ones. The device splits the particles to the largest number possible so it can mix better with the air and evaporate quickly in the combustion chamber. Results showed that use of the new device reduced the percentages of carbon monoxide (CO), the carbon dioxide (CO2) and the hydrocarbon. The mixing process is also improved as it is clear from the air–fuel ratio. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 761–765, 2018
