Abstract

EL CILINDRO DE COMBUSTION LENTA INCLUYE UNA CUBIERTA TUBULAR METALICA (G) QUE TIENE JUNTO CON EL TERMINAL CERRADO UN EMBUTIDO CONICO (G3) REALIZADO POR COMPACTACION CONICA DE LA MISMA CUBIERTA PARA CONSEGUIR EN LA ZONA EMBUTIDA, QUE SE EXTIENDE EN UNA PARTE DE LA OJIVA (K3), UN INCREMENTO DE LA RESISTENCIA A LA CORROSION TERMOQUIMICA DURANTE EL PRECALENTAMIENTO DEL MOTOR Y LA FASE DE FUNCIONAMIENTO. LA COMPACTACION CONICA PERMITE ADEMAS CONSEGUIR UN INCREMENTO DE LA CONSISTENCIA DEL POLVO DE AISLAMIENTO QUE VA HACIA LA INCLINACION DE LA PARTE DE LA CUBIERTA EMBUTIDA (G3). VENTAJAS: SE CONSIGUE MAYOR FIABILIDAD DEL CILINDRO DE COMBUSTION LENTA, UNA UNIFORMIDAD EN CUANTO A LA TEMPERATURA EN LA INCLINACION DE LA PARTE DE LA CUBIERTA EMBUTIDA Y UNA MEJOR CONFIGURACION EN EL TERMINAL CERRADO DE LA CUBIERTA. SE OBTIENE UN INCREMENTO DE LA DURACION DEL CILINDRO Y UNA MEJOR COMBUSTION DE LA MEZCLA DE AIRE Y COMBUSTIBLE. LA INVENCION SE MUESTRA EN LA FIGURA 3.
