Influence of fuel sulfur on the characterization of PM10 from a diesel engine

摘要: Abstract To study the effects of fuel sulfur content on characteristics diesel particle emitted from a typical engine used in China, two types with 30 ppm and 500 ppm were this dynamometer test under six operation conditions corresponding to 20%, 50% 80% load at 1400 rpm 2300 rpm speeds, respectively. Gaseous pollutants particulate matter (PM) emissions sampled AVL AMA4000 Model 130 High-Flow Impactor (MSP Corp), More specifically, PM mass, total carbon (TC), organic (OC), elemental (EC) water-soluble ion distribution also measured. Compared high diesel, application low can lower fuel-based by 9.2–56.6%. At 1400 rpm, decreased both OC EC 5–34% about 20%; while 2300 rpm, 33–57% increased emission, resulting OC/EC ratio. The evidence implicating that oxidation was promoted but effect dependent speed. linear regression has been conducted between TC PM10, slopes 0.88 0.80 for one, Higher sulfate detected 0.13 μm particles when using percentage 0.9% PM10 fuels. Comparing 500 ppm, sharply maximum 114% 2300 rpm.
