Abstract
CONTROL DE LA DISTRIBUCION DE LA INYECCION DE COMBUSTIBLE EN UN MOTOR DE IGNICION POR COMPRESION GENERANDO UNA SEÑAL DE COMIENZO DE LA COMBUSTION DENTRO DE LA CAMARA DE COMBUSTION.SE DETECTA (30) UNA PROPIEDAD DIRECTA DE LA COMBUSTION EN EL INTERIOR DE LA CAMARA (12) PROPORCIONANDO UNA SEÑAL REPRESENTATIVA DE LA MISMA. EL NIVEL DE CADA PROPIEDAD DE LA COMBUSTION ES CAMBIADO SENSIBLEMENTE AL COMIENZO DE LA COMBUSTION Y SE CONVIERTE LA PROPIEDAD DETECTADA EN UNA SEÑAL ELECTRICA INDICATIVA PRECISAMENTE DEL COMIENZO DE LA COMBUSTION EN DICHA CAMARA DE COMBUSTION.
