Abstract

EN UN INYECTOR DE COMBUSTIBLE DE ORIFICIOS MULTIPLES, DEL TIPO EN QUE LOS ORIFICIOS ESTAN CUBIERTOS POR UNA VALVULA (VCO), ESTOS (2) SON MAS GRANDES POR SUS EXTREMOS INTERIORES QUE POR LOS EXTREMOS EXTERIORES, POR EJEMPLO, SE ADELGAZAN EN CIERTA MEDIDA, PARA LOGRAR UNA PULVERIZACION CONCENTRADA. EL MEJOR METODO PARA REALIZARLOS ES POR MAQUINADO DE ELECTROEROSION.
