Application of Acoustic Agglomeration Technology to Improve the Removal of Submicron Particles from Vehicle Exhaust

The natural processes of interactions between aerosol particles in the ambient air through which they agglomerate is a vast area chamber research and are inherent to many industries often inter-connected with transport engineering. Further improvement symmetric methods for particle number mass concentration reduction made it possible create various synergic techniques. study used 1.9 TDI diesel internal combustion engine, was supplied (D100) second-generation biofuels (NExBTL100) EGR exhaust system on off. Measurements were performed using Bruel Kjær “Type 9727” measurement vibrations, scanning mobility sizer (SMPS) an original agglomeration chamber. three modes size distributions observed range from 10 470 nm both D100 NExBTL100 fuels without use system. application 21.3 kHz frequency sound SPL 144.1 dB changed generated but did not sufficiently affect emitted particles. greatest effect (21.7 ± 10.0%) extremely small derived (10–70 nm) when combination
