Abstract

LA INVENCION SE REFIERE A UN EQUIPO PARA LA RECONDUCCION DE GAS DE ESCAPE ENFRIADO DE MOTORES DE COMBUSTION INTERNA. EL GAS (5) DE ESCAPE A SER RECONDUCIDO SE GUIA EN UNO O MULTIPLES CHORROS (2) EN CONTACTO DIRECTO CON AIRE DE ENFRIAMIENTO POR MEDIO DE UN ENFRIADOR (1) DE GAS DE ESCAPE, DE FORMA TUBULAR. PREDOMINA UNA RELACION DE CORRIENTE LAMINAR, ES DECIR, EN BASE A LA MISMA DIRECCION DE CORRIENTE Y MISMA VELOCIDAD DE CORRIENTE DEL GAS DE ESCAPE Y DEL AIRE DE ENFRIAMIENTO NO APARECE NINGUN REMOLINO EN LOS CHORROS DE GAS DE ESCAPE LIGADOS. A PARTIR DE LOS CHORROS DE GAS DE ESCAPE LIGADOS PUEDE SER EXTRAIDO A TRAVES DE UNA CONDUCCION (4) DE EXTRACCION DE UNA TUBERIA (3) DE RECONDUCCION GAS DE ESCAPE REFRIGERADO, NO DILUIDO A PARTIR DEL ENFRIADOR DE GAS DE ESCAPE. ES VENTAJOSO QUE NO PUEDA APARECER NINGUNA SUCIEDAD DEL ENFRIADOR DEL GAS DE ESCAPE POR MEDIO DEL HOLLIN CONTENIDO EN EL GAS DE ESCAPE.
