Abstract

PROCEDIMIENTO Y DISPOSITIVO QUE PRETENDEN MEJORAR EL RENDIMIENTO DE UN MOTOR DE ENCENDIDO POR COMPRENSION A BAJAS Y ALTAS CARGAS Y EN EL ARRANQUE. CONSISTE EN MODIFICAR EL PERFIL Y CALADO DE LA DISTRIBUCION, DE FORMA QUE HAYA UN CAUCE DE VALVULAS EN LA CARRERA DE ESCAPE QUE PROVOQUE UNA CIERTA REABSORCION DE LOS GASES QUEMADOS. ANALOGAMENTE, EN LA CARRERA DE ADMISION LA VALVULA DE ADMISION DEBE CERRARSE LIGERAMENTE ANTES DEL P.M.I., CON LO CUAL LA CARRERA DE COMPRENSION EFECTIVA QUEDA RECORTADA EN LA PRACTICA. CON TODO ESTO SE PRETENDE AUMENTAR LA TEMPERATURA AL FINAL DE LA CARRERA DE COMPRENSION EN EL ARRANQUE Y A BAJAS CARGAS, Y LIMITAR LA PRESION FINAL A PLENA CARGA. EXISTEN VARIANTES DE PROCEDIMIENTO. DE APLICACION EN MOTORES DIESEL, SOBREALIMENTADOS O NO.
