We recently developed a novel diesel emissions control device, Electrostatic Screen Battery for Emissions Control (ESBEC), where diesel exhaust particles are collected onto metal screens using electrostatic principle. This paper focuses on further development of this technology: design and integration of a particle charger and testing of ESBEC with diesel exhaust. Two units - 0.038 and 0.152 m (1.5 and 6 inches) in diameter - were fabricated using 3D printing. Both units feature cylinder-shaped housing integrating the electrical charger and up to seven pairs of metal screens, which collect airborne particles. In the small-scale version, particles are charged by ions emitted from a carbon fiber brush, while in the large-scale version, this is done by using two tungsten wires traversing the cross-section of ESBEC in a crisscross pattern.
