Air circulation duct for air supply circuit of internal combustion engine, has main body traversed by set of tapered rigid metallic wires and set of elongated rigid metallic parts between which potential difference is established

摘要

The duct (1) has a main body (2) traversed by a set of tapered rigid metallic wires (6) and a set of elongated rigid metallic parts (10) between which potential difference is established, where the duct is made of composite material and presents a circular section. The potential difference is adjusted according to the distance separating the metallic wires and the metallic parts. The ratio between the potential difference and the distance separating the metallic wires and the metallic parts is higher than 10000 volt per centimeter.
