Abstract
The environmental and health threats from sub-micron particulate matter emitted in significant amount from automotive vehicles have prompted investigation of techniques capable of efficiently trapping particulates from engine exhausts. Simple analytical studies have indicated that filtration and use of electrostatic fields are effective in controlling particle emissions. A laboratory particulate trap based on combined metallic mesh and fibrous filter and a wire-cylinder electrostatic trap have been investigated on a diesel engine. The traps under development to reduce emissions from vehicles showed promising initial results. In the next phase of experimental and modelling work, the particulate oxidation at typical exhaust temperatures, using electrical heating will be examined.
