The article presents a technology for the recovery of diesel particulate filters (DPF) by means of an oxyhydrogen gas flame. The technology is developed and implemented by New Energy Corporation. The technology is carried on a disassembled DPF from engine exhaust system. The technological process involves activities such as: control of the initial technical condition of the contaminated DPF and preparations for recovery procedure; procedure for DPF recovery; control of DPF technical condition after recovering. The effectiveness of the applied technology has been tested in the laboratory base of the Technical University of Sofia, Department “Combustion engines, automotive engineering and transport”. The experimental test includes a quantitative assessment of the change in exhaust gases opacity and other indicators of a single-cylinder diesel engine operated without DPF, with contaminated DPF and with DPF after recovery.
