Effect of diesel detergent synergists on VOCs emissions from engine

In this study, the volatile organic compounds (VOCs) emissions from engine fueled diesel with and without detergent synergist were measured by gas chromatography mass spectrometry(GC-MS). The test results show that compared reference fuel (without synergist), use of different synergists has effects on VOCs while after-treatment device. Whether or device, alkanes always account for highest proportion fuels synergists. After-treatment device oxidation catalyst coupled particulate filter (DOC+DPF) high catalytic efficiency fuels, most could reach more than 95%. With treatment device,the concentrations carcinogens (detected in study) are far lower specified standard GBZ 2.1-2007 “Occupational Exposure Limits Hazardous Factors Workplace Chemical Factors”, respectively. indicate will not have an adverse impact human health it can be safely used.
