Abstract
EN VALVULA DE INYECCION DE TIPO PREVIAMENTE CONOCIDO, CUANDO EL MOTOR DE COMBUSTION INTERNA ESTA CALIENTE, ESPECIALMENTE EN ARRANQUES EN CALIENTE O EN CONDICIONES DE FUNCIONAMIENTO EN VACIO EN CALIENTE, SE EVAPORA EL COMBUSTIBLE ANTES DEL DISCO DE LAS TOBERAS DE INYECCION Y EN LAS TOBERAS DE INYECCION, DE TAL FORMA QUE EL RESULTADO DE ELLO AFECTA DE FORMA ADVERSA AL FUNCIONAMIENTO DEBIDO AL BAJO SUMINISTRO DE COMBUSTUBLE. EL FUNCIONAMIENTO DEL MOTOR DEBE SER POR TANTO MEJORADO MEDIANTE LA PREVENCION DE LA FORMACION DE BURBUJAS DE VAPOR. LA PROVISION DE UN COMPONENTE DE TRANSICION REDUCIENDO LA TRANSFERENCIA DE CALOR ENTRE EL CUERPO (16) DE ASIENTO DE VALVULA Y EL DISCO (21) DE TOBERA DE INYECCION EN FORMA DE UN ESCALON (18) ELEVADO FORMADO SOBRE EL CUERPO (16) DE ASIENTO DE VALVULA ASEGURA QUE SE ENFRIE EL DISCO DE TOBERAS DE INYECCION Y COMO RESULTADO LA REDUCCION DEL CALOR DE EVAPORACION DEL COMBUSTIBLE INYECTADO, DE TAL FORMA QUE SE REDUCE EL RIESGO DE FORMACION DE BURBUJAS DE VAPOR EN OANTES DE LAS TOBERAS (25) DE INYECCION. LA VALVULA DE INYECCION DE COMBUSTIBLE ES ESPECIALMENTE ADECUADA PARA SISTEMAS DE INYECCION DE COMBUSTIBLE EN MOTORES DE COMBUSTION INTERNA DE MEZCLA DE COMPRESION CON IGNICION DE CHISPA.
