Abstract
SEGUN LA INVENCION, EN UN MOTOR DE INYECCION PARA EL QUE LA DURACION DE INYECCION DE BASE ES DETERMINADA EN FUNCION DE UN DECALAJE Y DE UNA GANANCIA DE UNA RECTA QUE EXPRESA ESTA DURACION EN FUNCION DE LA PRESION EN LA TUBULADURA, PARA UN REGIMEN DADO, SE PROHIBE LA AUTOADAPTACION POR MODIFICACION DE LA GANANCIA O DEL DECALAJE SIMULTANEAMENTE AL CAUDAL DE UNA VALVULA DE PURGA DEL BOTE, Y SE AUTORIZA LA AUTOADAPTACION RESPECTIVAMENTE EN DECALAJE O EN GANANCIA DURANTE A LO SUMO UN NUMERO MAXIMO DE N1 O N2 CICLOS, EN UNA ZONA DE FUNCIONAMIENTO 1 DE BAJA PRESION, O RESPECTIVAMENTE 2 DE ALTA PRESION, NO SE AUTORIZA EL CAUDAL DE LA VALVULA DE PURGA MAS QUE DESPUES DE LA EJECUCION DEL NUMERO MAXIMO DE N1 O RESPECTIVAMENTE N2 CICLOS, Y NO SE PERMITE UNA NUEVA AUTOADAPTACION EN GANANCIA COMO EN DECALAJE MAS QUE DESPUES DE LA EJECUCION DE TODOS LOS CICLOS PERMITIDOS EN GANANCIA Y EN DECALAJE. APLICACION EN LOS MOTORES DE INYECCION CON CIRCUITO DE PURGA DE BOTE Y AUTOADAPTACION DE LA RIQUEZA A PARTIRDE UNA SONDA LAMBDA EN LOS GASES DE ESCAPE.ACCORDING TO THE INVENTION, IN AN INJECTION ENGINE FOR WHICH THE BASE INJECTION DURATION IS DETERMINED IN FUNCTION OF A DECALAGE AND OF A GAIN OF A STRAIGHT LINE THAT EXPRESSES THIS DURATION IN FUNCTION OF THE PRESSURE IN THE PIPE, FOR A GIVEN REGIME, SELF-ADAPTATION IS PROHIBITED BY MODIFICATION OF THE GAIN OR DECALAGE SIMULTANEOUSLY AT THE FLOW OF A BLEED PURGE VALVE, AND SELF-ADAPTATION IS AUTHORIZED RESPECTIVELY DURING A SUM OF A MAXIMUM N1 OR N1 LOW PRESSURE OPERATING 1, OR RESPECTIVELY 2 HIGH PRESSURE, THE PURGE VALVE FLOW IS NOT AUTHORIZED RATHER THAN AFTER THE MAXIMUM NUMBER NUMBER IS PERFORMED OR RESPECTIVELY N2 CYCLES, AND A NEW SELF-ADAPTATION IS NOT PERMITTED AS GAIN IN SHORTAGE MORE THAN AFTER THE EXECUTION OF ALL THE CYCLES ALLOWED IN GAIN AND SHARING. APPLICATION IN INJECTION ENGINES WITH BOAT PURGE CIRCUIT AND WEALTH SELF-ADAPTATION FROM A LAMBDA PROBE IN THE EXHAUST GASES.
