Abstract

EL METODO CONSISTE ESENCIALMENTE EN HACER QUE EL MOTOR (9) EXPERIMENTE AL MENOS UN CICLO COMPLETO SIN ALIMENTACION, PARA DETERMINAR SECUENCIALMENTE LA COMPRESION EN LA CAMARA DE COMBUSTION (31, ..., 36) DE CADA CILINDRO (1, ..., 6), Y MEDIR LA INTENSIDAD DE LA SEÑAL ULTRASONICA GENERADA POR EL EFECTO DE CUALQUIER FILTRACION INDEBIDA DEL AIRE PRESURIZADO ENTRE CITADA CAMARA DE COMBUSTION (31, ..., 36) Y UN CONDUCTO DE ENTRADA (51) Y/O UN CONDUCTO DE SALIDA (52) (CAUSADA POR PERDIDAS DE ESTANQUEIDAD EN LAS VALVULAS DE ENTRADA Y/O DE SALIDA, O POR CONTACTO ANOMALO DE LA VARILLA DE LEVANTAMIENTO O LEVA RESPECTIVA) Y/O UN COMPARTIMENTO (3) DE SUMIDERO DE ACEITE (65) POR ENCIMA DEL NIVEL DE ACEITE (OCASIONADO POR PERDIDA EN LA ESTANQUEIDAD EN LOS ANILLOS DEL PISTON).
