Sierra CP Diesel Engine Particle Emission Transient Sampling System
Vehicle/engine manufacturers are facing increasing environmental protection regulations regarding particulate matter emissions. Previously in the United States, the National Environmental Protection Agency issued regulations requiring engine manufacturers to use a full flow dilution channel sampling system for transient emission testing. Now BG-3 is recognized by EPA as equivalent to a full flow dilution channel device. In 2011, its design was also designed to comply with the regulations for conducting single filter paper testing. Furthermore, the emergence of BG3 has provided an alternative device for full flow dilution channels. Engine manufacturers now have unprecedented flexibility in choosing different dilution sampling equipment. This not only reduces costs, but also improves the quality of testing. BG-3 has now been recognized by EPA and can be equivalent to a full flow dilution channel system, which can be applied to all models of engines currently available.
Sierra CP recommends the BG-3 partial flow particle sampling system, which can replace the full flow dilution sampling system in steady-state and transient tests. Meet the requirements of European regulations III, IV, V, and VI for the certification testing of heavy-duty vehicle engines. BG-3 complies with ISO 8178 and European TUV standards. BG-3 also meets the requirements of US 40 CFR 1065 and international standard ISO 16183 for equivalent alternative full flow dilution sampling systems. BG-3 can further meet the particle emission testing standards for light-duty vehicles in China's National Standard No. 5.
BG-3 is fully automated, saving equipment and operating costs, easy to move, precise to test, suitable for various engines, different engine speeds, different power outputs, and different exhaust tailpipe sizes. The sampling time can be adjusted according to the requirements of different experiments and different testing steps.
In addition to regulatory certification work, BG-3 can also be used for engine development, combustion, and emission research. BG-3 can also be used for emission testing of light-duty vehicles and research on crankcase leakage emissions. Once engineers master the application of BG-3, it feels like they have entered a new world.
The pollution measurement of diesel particulate matter has always used expensive full flow dilution channels. In today's increasingly strict and widespread control of diesel particulate emissions. A convenient, economical, accurate, and equivalent method to a full flow dilution channel must be adopted. The BG3 partial flow particle sampling system of SIERRA was approved by the US Environmental Protection Agency in February 2011 as a partial flow particle sampling device that can replace the full flow dilution channel. The CADET control system of CP also makes BG3 more complete. If combined with EST's self-developed particle weighing system in Beijing, which has world-class standards, the sampling and weighing of diesel particulate matter can reach a new level.
