DEVICE FOR THE REMOVAL OF SOLID PARTICLES FROM COMBUSTION ENGINE EXHAUST GASES

摘要

The exhaust gas cleaning system for a vehicle enqine includes a tube connected to the exhaust pipe, with a central support from end to end, carrying a set of equally spaced disc electrodes. These produce a corona discharge with the tube wall, which combines fine particles to form longer particles. Due to the speed of gas flow which is higher than 2.5 m/sec., the large particles are carried onwards to the end of the tube, using a swirling action. There, they enter a centrifugal separator where the clean gases are discharged through a tube one end, and the gases containing a high proportion of soot are discharged through another tube.
