Abstract

MEDICION DE LA COMPRESION DE CADA CILINDRO EN UN MOTOR DE COMBUSTION INTERNA. CONSTA DE LAS SIGUIENTES ETAPAS: DETECTAR LA VELOCIDAD ANGULAR ABSOLUTA DEL CIGUEÑAL DE UN MOTOR Y RELACIONAR VARIACIONES DE ESTA Y DETECTAR COMO CILINDROS EN FALLO AQUELLOS EN LOS QUE EL TRABAJO DE COMPRENSION Y EXPANSION, SON INFERIORES A LOS QUE DESARROLLARIAN CILINDROS IDEALES, PREVIAMENTE DISEÑADOS. LAS MEDIDAS OBTENIDAS DE ESTE MODO, DEBEN SER TRABAJADAS MATEMATICAMENTE DE MODO QUE EXPRESEN EN MODO NUMERICO LA REALIDAD FISICA DEL MOTOR QUE REPRESENTAN.
