H SUB(2)O SUB(2) ADDITION TO DIESEL ENGINE EXHAUST GAS AND ITS EFFECT ON PARTICLES

This paper describes a program of particle measurements of 2 different direct injection diesel engines that was performed in which the effect of H sub(2)O sub(2) addition to the exhaust gas on particle emissions was observed. A DDMA-system consisting of 2 synchronously operating DMA-CPC systems, one equipped with a thermolysis tube, was used to separate the effect of H sub(2)O sub(2) addition on the solid and on the volatile particle material. Results indicate that the effect on solid particle material is very weak due to a lack of reaction time. This result was confirmed by Bosch Smoke Number measurements. Conversely, a clear effect of H sub(2)O sub(2) addition on the volatile particle fraction was observed. Additionally performed tandem DMA measurements gave hints as to the kind of volatile species.
