Dynamics of soot formation and burnout in a gas diesel cylinder

Abstract

Combustion of the methane-air mixture can be accompanied by intensive formation and burning of soot, which will lead to an increase in heat losses and heat stress of the chilindro-piston group. The complexity and difficulty of registering the concentration of instantaneous soot particles make it difficult to study the laws of soot formation kinetics in gas diesel. The mechanism of soot formation during combustion of a methane-air mixture in a gas-diesel fuel is even more complex and less studied, since there is charge heterogeneity and other supercritical parameters. The paper proposes a mathematical model of soot formation and burnout in a gas diesel cylinder, which attempts to take into account the features of combustion of atomized fuel and methane-air mixture.
