Sensores de presi\u00f3n absoluta - MAP<\/p>\n
C\u00f3mo funciona:
\nPara optimizar la mezcla de aire y combustible y mejorar el rendimiento de la combusti\u00f3n y el encendido, el volumen de aire admitido en el motor debe controlarse y ajustarse constantemente. Los sensores de presi\u00f3n absoluta del colector (MAP) son esenciales para este proceso.
\nEl sensor MAP, un sensor de vac\u00edo semiconductor compacto, aprovecha el efecto de resistencia piezoel\u00e9ctrica, en el que la resistencia el\u00e9ctrica cambia cuando se aplica presi\u00f3n al silicio. Este efecto se utiliza para medir la presi\u00f3n en el colector de admisi\u00f3n aguas abajo de la v\u00e1lvula de mariposa. La medici\u00f3n de la presi\u00f3n se transmite a la ECU del motor mediante se\u00f1ales el\u00e9ctricas y se utiliza para calcular el volumen de aire de admisi\u00f3n. Una vez calculado, la ECU puede ajustar el rendimiento del motor para garantizar un control \u00f3ptimo de la relaci\u00f3n aire-combustible.
\nAunque esta es la funci\u00f3n principal de los sensores MAP, estas piezas tambi\u00e9n se utilizan para medir la presi\u00f3n de sobrealimentaci\u00f3n que entra en la v\u00e1lvula de mariposa y la presi\u00f3n de la galer\u00eda del turbo para optimizar el rendimiento del motor en entornos severos de turboalimentaci\u00f3n o sobrealimentaci\u00f3n.<\/p>\n
Caracter\u00edsticas y ventajas:<\/p>\n
\u2981 El montaje de chip desnudo implica menos componentes y un tama\u00f1o compacto.
\n\u2981 La cancelaci\u00f3n de ruido en chip reduce el n\u00famero de componentes necesarios.
\n\u2981 Superficie duradera de dos capas que hace frente al duro entorno del colector de admisi\u00f3n.
\n\u2981 Las conexiones Link ofrecen una mayor fiabilidad y una instalaci\u00f3n m\u00e1s sencilla.<\/p>\n
\u00bfCu\u00e1les son los posibles fallos de los sensores MAP?<\/p>\n
\u2981 Cualquier sustancia o humedad elevada en el aire de admisi\u00f3n que entra en el orificio de presi\u00f3n puede provocar un fallo de los sensores MAP.
\n\u2981 Las fugas de vac\u00edo en los sistemas del colector de admisi\u00f3n o en la manguera que conecta el sensor MAP con el motor pueden provocar el mal funcionamiento del sensor MAP.
\n\u2981 Los cortocircuitos y las aberturas en el circuito de cableado del sensor MAP pueden causar una discrepancia en las caracter\u00edsticas o un mal funcionamiento.<\/p>\n
\u00bfCu\u00e1les son los s\u00edntomas de los sensores MAP?<\/p>\n
\u2981 P\u00e9rdida de potencia del motor.
\n\u2981 Ralent\u00ed \u00e1spero e inestable.
\n\u2981 Conducci\u00f3n deficiente, incluyendo vacilaci\u00f3n durante la aceleraci\u00f3n.
\n\u2981 Se bloquea poco despu\u00e9s de arrancar o al pisar o soltar el acelerador.<\/p>\n
\u00bfC\u00f3mo prevenir y solucionar los fallos del sensor MAP?<\/p>\n
\u2981 Un problema con el sensor MAP puede hacer que se encienda la l\u00e1mpara de advertencia del motor. Este fallo se almacena en el c\u00f3digo de diagn\u00f3stico de aver\u00edas (DTC) en la ECU del motor (P0105...P0109) y puede inspeccionarse con una herramienta de escaneo de DTC.
\n\u2981 Un sensor MAP defectuoso puede no inutilizar el veh\u00edculo, pero debe ser reemplazado tan pronto como sea posible para evitar posibles da\u00f1os al motor en condiciones de combustible rico o pobre causadas por un mal funcionamiento del sensor MAP.
\n\u2981 Aseg\u00farese de que no hay anomal\u00edas en el vac\u00edo del colector de admisi\u00f3n debido a fugas u otros problemas del sistema.<\/p>","protected":false},"excerpt":{"rendered":"
