Abstract

This paper deals with controlling of the DPF filter regeneration. Our field of study is electrically burned DPFs. The paper contains the results of the burning tests and their comments. A task of the DPF regeneration is to burn soot accumulated in DPF. This needs to reach a sufficient temperature but not to exceed the safe temperature. Possibilities for determining a temperature in the filter are discussed. Advantages and disadvantages of these methods are described. For the real application one of them was chosen. A prototype of control device was designed.
