【 摘 要 】

In the paper an original design of the ozone-catalytic device, in which the process of ozone formation occurs directly inside the catalytic block of the honeycomb structure, is proposed for solving of problem of exhaust gases purification at a cold start of an automobile engine. For considered device the regime of operation at the absence of cooling is considered and the equations, allowing us to calculate the degree of heating and the decrease of the stationary concentration of ozone depending on the time, are obtained. Results of mathematician modelling were confirmed by experimental researches.
