The EGR System for Diesel Engine Using a Low Voltage Soot Removal Device
EGR system is considered to be the most effective way of reducing the pollution, especially NOx, from diesel engine exhaust gas. However, EGR system is hampered by soot accumulation.
In this study, a low-voltage soot removal device was installed at the air inlet in the EGR system.
Measurements made with a Bosch smoke meter indicated that use of this device resulted in about a 50 - 84% reduction of soot, which would enable continuous use of EGR in diesel engines.
The soot accumulated at the filter was easily removable and combustible into CO
