Abstract

SISTEMA PARA CONTROLAR UN MOTOR DE ENCENDIDO DE CHISPA PARA HACER MAXIMO LA EFICACIA DEL COMBUSTIBLE SOBRE TODO LA GAMA DE SUS CONDICIONES DE OPERACION. EL SISTEMA INCLUYE UN APARATO (20) PARA CONTROLAR LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO AL MOTOR Y UN APARATO (26) PARA MEDIR LA PRESION DEL CILINDRO INTERNO EN AL MENOS UN CILINDRO DEL MOTOR. HAY UN APARATO PROVISTO PARA HACER UNA ESTIMACION DE LA MASA DE AIRE QUE ENTRA AL MOTOR Y UN APARATO (26) PARA MEDIR LA PRESION DEL CILINDRO INTERNO EN AL MENOS UN CILINDRO DEL MOTOR. HAY UN APARATO PROVISTO PARA HACER UNA ESTIMACION DE LA MASA DE AIRE QUE ENTRA AL MOTOR Y UN ORDENADOR (20) CALCULA LA EFICACIA DEL MOTOR DESDE LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO , LA PRESION DEL CILINDRO INTERNO Y LA ESTIMACION DE LA MASA DE AIRE QUE ENTRA EN EL MOTOR. EN UNA REALIZACION, LA EFICACIA SE MIDE CALCULANDO EL CONSUMO APROXIMADO DE COMBUSTIBLE ESPECIFICO INDICADO. HAY UN APARATO (20) PROVISTO PARA VARIAR LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO AL MOTOR PARA NUNIMIZAR EL CONSUMO DE COMBUSTIBLE ESPECIFICO INDICADO SOBRE TODA LA GAMA DE CONDICIONES DE OPERACION DEL MOTOR. EN ESTA REALIZACION, HAY UN APARATO PROVISTO PARA SUMINISTRAR UNA MAYOR CANTIDAD DE COMBUSTIBLE MAS ALLA DEL PUNTO DE MAXIMA EFICACIA DE LA POSICION DE LA PLACA DE ESTRANGULACION AMPLIAMENTE ABIERTA
