Abstract

SE SABE QUE, DURANTE LAS CONDICIONES DE FUNCIONAMIENTO ESPECIALES, EJ. CALENTAMIENTO, ACELERACION, CONDICIONES DE PLENA POTENCIA, EL ESTABLECIMIENTO DE LA MEZCLA SE EFECTUA MEDIANTE UN SISTEMA DE CONTROL EN LUGAR DE MEDIANTE UN AJUSTE LANDA. ESTO PUEDE DAR COMO RESULTADO UNA MEZCLA POBRE. LA INVENCION INTENTA EVITAR ESTO A PARTE DE ASEGURARSE QUE EL AJUSTE LAMBDA PERMANECE EN FUNCIONAMIENTO DURANTE LAS CONDICIONES DE FUNCIONAMIENTO ESPECIALES, DENTRO DE UNA GAMA RESTRINGIDA. SE SUPERPONE EN EL CONTROL DEL PILOTO Y SOLO TIENE EFECTO EN EL SENTIDO DE ENRIQUECIMIENTO .
