Abstract

SE PROPONE UNA INSTALACION DE IGNICION PARA MOTORES DE COMBUSTION INTERNA QUE DISPONE DE UN CIRCUITO (10,11,12,16) DE UNION PARA LA LIMITACION DE LA TENSION PRIMARIA Y PROTECCION DE LAS PARTES QUE CONDUCEN A ALTA TENSION CONTRA DESTRUCCION. LA INSTALACION DE IGNICION TIENE UN DISPOSITIVO DE FIJACION DE TENSION PARA EL TRANSISTOR (3) DE IGNICION, Y EL VOLTAJE ES UNA VARIABLE DEPENDIENDO DE LA CARGA EN EL LADO SECUNDARIO. LA TENSION (UP) ES DETERMINADA MEDIANTE UNA UNIDAD (9) DE EVALUACION. CUANDO LA CARGA SECUNDARIA ES ALTA, SE APLICA UN ALTO VOLTAJE DE LIMITACION, Y CUANDO LA CARGA SECUNDARIA ES BAJA, SE APLICA UN VOLTAJE BAJO DE LIMITACION. ADEMAS, LA EVALUACION (2328) DE LA TENSION PRIMARIA PERMITE EL DIAGNOSTICO DE FALLOS EN LA INSTALACION DE IGNICION.AN IGNITION INSTALLATION FOR INTERNAL COMBUSTION ENGINES IS PROPOSED THAT HAS A UNION CIRCUIT (10,11,12,16) FOR THE LIMITATION OF THE PRIMARY VOLTAGE AND PROTECTION OF THE PARTS THAT DRIVE TO HIGH VOLTAGE AGAINST DESTRUCTION. THE IGNITION FACILITY HAS A VOLTAGE FIXING DEVICE FOR THE IGNITION TRANSISTOR (3), AND THE VOLTAGE IS A VARIABLE DEPENDING ON THE CHARGE ON THE SECONDARY SIDE. THE TENSION (UP) IS DETERMINED THROUGH AN EVALUATION UNIT (9). WHEN THE SECONDARY CHARGE IS HIGH, A HIGH LIMITATION VOLTAGE APPLIES, AND WHEN THE SECONDARY CHARGE IS LOW, A LOW LIMITATION VOLTAGE APPLIES. FURTHER, THE EVALUATION (2328) OF THE PRIMARY VOLTAGE ALLOWS THE DIAGNOSIS OF FAILURES IN THE IGNITION INSTALLATION.
