Abstract
The device which has been evaluated traps the lead emissions in the exhaust system. The lead trap was made to a patented design and replaced the expansion and silencer boxes in a conventional exhaust system with boxes filled with stainless steel wool which were then coated with alumina and calcite. The volume of the boxes used for the lead traps was approximately 5 times the displacement volume of the engine. The results of the assessment of the lead trap are presented.
