Sabertec releases results from filter tests
In July, Sabertec presented the Impact Diesel Particulate Filter (IDPF), a new type of technology for reducing emissions into the atmosphere of particulate material from diesel-powered engines. The company has now announced the final results from the tests carried out on the equipment, which were conducted by the Experimental Atmospheric Pollution Laboratory of the Department of Pathology of the School of Medicine of USP.
The final report revealed a significant reduction in emissions, with a retention rate of up to 70% of the particulate material of diameter ≤ 2.5 micrometers (PM 2.5). In 2005, PM 2.5 was identified by the World Health Organization as one of the polluting elements that is most harmful to human health.
The particulate material results from a mixture of solid or liquid particles suspended in the air, which vary in shape and diameter. The fine particles, with diameters of less than 2.5 micrometers, are especially damaging, because they deeply invade the human respiratory system, without any type of defense.
The filter was conceived by the engineer Sergio Sangiovani. Differing from conventional catalyzers, the IDPF can be used in vehicles powered by diesel with high sulfur content, as is the case with Brazilian diesel and the diesel in many developing countries. Moreover, the IDPF does not convert the particulate material into CO2.
To determine parameters and protocols for testing the efficiency of the reduction in the IDPF, Sabertec could count on support from a variety of entities, including the Experimental Atmospheric Pollution Laboratory of the Department of Pathology of the School of Medicine of USP (FMUSP), and from the Department of Green and Environment of the municipality of São Paulo. The Interlagos Race Circuit served as the stage on which the scientists and engineers simulated normal traffic condition, using a bus assigned from São Paulo’s fleet. The route reproduced stops, accelerations, climbs, descents and curves.
“We are extremely confident regarding the test results obtained at Interlagos. We believe that the IDPF technology represents a significant opportunity to improve São Paulo’s air quality. It has been proven that the high technology of the IDPF is appropriate for the type of diesel used in Brazil. It is technology that is already available in the market”, states Bill O’Brien, CEO of Sabertec.
