Abstract

The electrostatic precipitator (ESP) with heat exchanger was developed to reduce particles and SO2 in a diesel engines. The influence of gas cooling on the particle and SO2 concentrations was investigated using a 400 cc diesel engine. The particle concentrations were measured with a scanning mobility particle sizer (SMPS) and a low volume air sampler. Soluble Organic Fraction (SOF) and SO42-, which make up the composition of the particle, were also evaluated using a soxhlet extractor and an ion chromatography. SO2 concentration was measured with a UV fluorescence SO2 monitor. <BR>The results show that the number and the volume concentration of particles increased due to generated SOF and sulfuric acid particles by gas cooling. It was also indicated that SO2 concentration in the gas was reduced due to absorption into condensed water. Although the particle concentration increased, ESP showed a high particle collection efficiency.
