The formation of soot in the cylinder of a diesel engine when operating on methanol-containing motor fuel

Abstract

Abstract The chemistry of the formation of soot particles in a cylinder of a diesel engine when working on alternative motor fuel in the form of an emulsion containing methanol alcohol is considered. One of the most dangerous toxic components of liquid fuel combustion products is soot. Therefore, it is necessary to find ways to reduce its content. To do this, you need to know the methods and stages of soot formation, which affect the final concentration by weight. The most important task can be called the determination of the prevailing mechanisms of the appearance of soot in the combustion of liquid fuels in the cylinders of engines. A variable zonal model of soot formation in a 4 H 11.0 / 12.5 high-speed diesel engine is presented when working on an alternative emulsified alcohol fuel - methanol-fuel emulsion. The stages of the formation of carbon particles during the oxidation of fuel inside the cylinder are considered.
