Abstract

UN MOTOR DE COMBUSTION INTERNA DE EMBOLO DE LEVANTAMIENTO DE DOS TIEMPOS DE ENCENDIDO EXTERNO CON UN IRRIGADOR DE LA CAJA DEL CIGUEÑAL TIENE UNA TOBERA DE INYECCION DEL CARBURANTE Y UN ORGANO DE ESTRANGULACION (11) QUE TIENE BOCAS DE CIERRE (12, 15) ABIERTAS DENTRO DE LA ENTRADA DE AIRE. PARA CONSEGUIR UN BUEN COMPORTAMIENTO DE REACCION Y BUENOS VALORES EN LA CARGA DE LAS PIEZAS Y CON EL FIN DE EVITAR LA MEZCLA DE AIRE-CARBURANTE NO DESEADO A LA HORA DE ABRIR RAPIDAMENTE EL ORGANO DE ESTRANGULAMIENTO (11) , LAS BOCAS DE CIERRE (12, 15) ESTAN AJUSTADAS DIRECTAMENTE AL ORGANO DE ESTRANGULACION (11). ADEMAS, EL ORGANO DE ESTRANGULACION (11) ESTA FORMADO DE MANERA QUE DEJA LIBRE UN RAMAL (14) DEL AJUSTE BAJO CARGA PARCIAL DETERMINADO DE LA MARCHA DE RALENTI, QUE VA HACIA EL CAMPO DE LA BOCA (8'') DE LA TOBERA DE INYECCION DEL CARBURANTE (8) Y QUE TIENE ALGUNAS BOCAS DE CIERRE (15). LA ANCHURA DE LA LUZ DEL RAMAL (14) TIENE SOLAMENTE UNA FRACCION DE LA ENTRADA TOTAL DE LA ANCHURA DE LA LUZ.
