Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA EL REGISTRO DE LA CANTIDAD DE COMBUSTIBLE TRANSPORTADA POR UNA BOMBA DE INYECCION DE UN MOTOR DIESEL A TRAVES DE LAS TOBERAS DE INYECCION. LA CANTIDAD DE COMBUSTIBLE ABSOLUTA PUEDE SER DETERMINADA DE FORMA SENCILLA Y APLICADA PARA INDICACION, DE TAL MODO QUE SE NORMALIZA LA CURVA DE DESARROLLO DE PRESION OBTENIDA POR MEDIO AL MENOS DE UN SENSOR DE SEÑAL DE TRANSPORTE, DE TAL MODO QUE SE CONFIGURA A CONTINUACION LA INTEGRAL DE SUPERFICIE DE LA CURVA DE DESARROLLO DE PRESION NORMALIZADA Y SE DETERMINA A TRAVES DE LA VALORACION LA CANTIDAD DE COMBUSTIBLE ABSOLUTA CON UNA CONSTANTE DE PROPORCIONALIDAD. EL PROCEDIMIENTO Y UN EQUIPO CORRESPONDIENTE PUEDEN SER APROVECHADOS PARA LA DETERMINACION DEL CONSUMO DE COMBUSTIBLE EN UN AUTOMOVIL O PARA LA DIAGNOSIS EN UN BANCO DE PRUEBAS DE BOMBA DE COMBUSTIBLE.THE INVENTION REFERS TO A PROCEDURE FOR REGISTRATION OF THE AMOUNT OF FUEL CARRIED BY A DIESEL ENGINE PUMP THROUGH THE INJECTION NOZZLES. THE QUANTITY OF ABSOLUTE FUEL MAY BE DETERMINED SIMPLY AND APPLIED FOR INDICATION, IN A WAY THAT THE PRESSURE DEVELOPMENT CURVE OBTAINED THROUGH AT LEAST A TRANSPORTATION SIGNAL SENSOR IS CONFORMED, AS WELL CONFIGURED INTEGRAL SURFACE OF THE NORMALIZED PRESSURE DEVELOPMENT CURVE AND IS DETERMINED THROUGH THE VALUATION THE AMOUNT OF ABSOLUTE FUEL WITH A PROPORTIONAL CONSTANT. THE PROCEDURE AND A CORRESPONDING EQUIPMENT MAY BE USED FOR THE DETERMINATION OF FUEL CONSUMPTION IN A CAR OR FOR DIAGNOSIS IN A FUEL PUMP TESTING BANK.
