Abstract

LA INVENCION CONCIERNE A UN PROCESO DE MANDO DE LOS INYECTORES DE UN MOTOR EN ENCENDIDO MANDADO E INYECCION MULTIPUNTO, DE CUATRO CILINDROS Y DE CUATRO TIEMPOS, SEGUN EL CUAL SE AGRUPAN LOS INYECTORES POR PARES, SE MANDA LA ABERTURA DE LOS INYECTORES DE CADA PAR UNA SOLA VEZ POR CICLO MOTOR, Y DE MODO QUE EL SECUENCIAMIENTO D MANDO DE LOS DOS PARES SEA INSENSIBLE AL FASAJE DEL MOTOR, Y, ADAPTANDO PARA LOS INYECTORES EL INDEXADO DE LOS CILINDROS DEL MOTOR, SE PAREAN LOS INYECTORES 1 Y 4 POR UNA PARTE Y LOS INYECTORES 2 Y 3 POR OTRA PARTE, SE INICIA LA INYECCION DE CADA UNO DE LOS DOS PARES DE INYECTORES 1-4 Y 2-3 EN EL CURSO DE UNA RESPECTIVAMENTE DE DOS SEMIVUELTAS DE MOTOR SUCESIVAS, Y SE HACE SEGUIR ESTOS DOS MANDOS DE DOS SEMIVUELTAS DE MOTOR SUCESIVAS SIN MANDO DE INYECTORES, LUEGO SE VUELVE A TOMAR LA SECUENCIA MIENTRAS EL MOTOR ES MANDADO EN FUNCIONAMIENTO SINCRONO.THE INVENTION CONCERNS A CONTROL PROCESS OF THE INJECTORS OF AN ENGINE COMMANDED IGNITION AND MULTI-POINT INJECTION, FOUR CYLINDERS AND FOUR TIMES, ACCORDING TO WHICH THE INJECTORS ARE GROUPED BY PARENTS, THE OPENING OF THE INJECTORS IS SENT ONLY PER ENGINE CYCLE, AND SO THAT THE SEQUENCING D CONTROL OF THE TWO PAIRS IS INSENSITIVE TO THE ENGINE PHASE, AND, ADAPTING FOR THE INJECTORS THE INDEX OF THE ENGINE CYLINDERS, THE INJECTORS 1 AND 4 ARE STOPPED ON THE ONE PART AND INJECTORS 2 AND 3 ON THE OTHER HAND, INJECTION OF EACH OF THE TWO PAIRS OF INJECTORS 1-4 AND 2-3 IS INITIATED IN THE COURSE OF ONE RESPECTIVELY TWO SUCCESSIVE ENGINE SEMI-TURNS, AND THESE TWO CONTROLS ARE FOLLOWED TWO SUCCESSIVE SEMI-TURNS OF ENGINE WITH NO INJECTOR CONTROL, THEN THE SEQUENCE IS TAKEN AGAIN WHILE THE ENGINE IS COMMANDED IN SYNCHRONOUS OPERATION.
