Inyección directa o para lo que necesita boquillas en el motor.

La inyección directa es la mezcla de la inyección de combustible distribuida, donde se inyecta directamente el combustible en los cilindros. La boquilla es el componente de unión principal entre la bomba de combustible y el motor. El propósito principal de las boquillas:

  1. Asegurar la dosis correcta del combustible suministrado al motor.
  2. Asegurando el chorro correcto (cantidad, presión, ángulo) de la mezcla.

Boquilla electromagnética, dispositivo y principio de trabajo.

Dichos dispositivos electromagnéticos se utilizan, como regla general, en motores de gasolina, incluso con inyección directa. Este tipo de equipo tiene un diseño bastante simple que consiste en:

  1. Boquilla de la boquilla.

  6. Primavera especial.
  7. Desinversión electromagnética de excitación.
  8. Conector eléctrico.
  9. Filtro de malla.

La boquilla realiza salpicaduras de combustible. Es de la calidad de la operación de este componente depende de la operación de todo el dispositivo. El filtro de malla filtra el combustible que pasa a través de la boquilla.

ECU, correspondiente al algoritmo establecido previamente, en el momento requerido garantiza el suministro de voltaje al devanado de la excitación de la válvula. En el proceso de esto, se produce un campo electromagnético, superando la fuerza de resorte, después de lo cual retrasa un anclaje con una aguja, que libera la boquilla. Después de todo esto es la inyección de combustible. Cuando el voltaje desaparece, la aguja de la boquilla vuelve a la silla usando la primavera.

Boquilla Diesel, Boquillas De Motor Diesel, Dispositivo y Principio de Operación

004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuugauguuuuuuu

En los motores diesel, incluidos los equipados con el sistema de inyección "Riel común", se utilizan boquillas electrohidráulicas. El diseño de este dispositivo incluye una válvula electromagnética, una cámara de control, así como un estrangulamiento de desagüe y admisión.

004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuugauguuuuuuu

El principio de operación de dicho equipo se basa en el uso de la presión del combustible durante la inyección, así como, después de su terminación. En la posición inicial, la válvula solenoide está completamente cerrada y desenergizada, la aguja del dispositivo se presiona en la silla de montar con una presión sobre el pistón de combustible en la cámara de control. La inyección de combustible en esta posición no se realiza. Vale la pena señalar que la presión del combustible en la aguja, en esta situación, menos presión, que se produce en el pistón, como resultado de la diferencia en las áreas de contacto.

Después del comando de la ECU, se activa la válvula solenoide y se abre el acelerador de drenaje. Combustible, que se encuentra en la cámara de control, mientras que fluye a través del acelerador en la carretera de desagüe. El estrangulador de admisión es un obstáculo para la nivelación más rápida de las presiones en la línea de entrada y la cámara de control. Sin embargo, gradualmente existe una disminución de la presión sobre el pistón, la presión del combustible ejercida en la aguja no cambia, lo que resulta en elevar la aguja y la inyección de combustible.

Piezohoroforsunk, principio de trabajo

El funcionamiento de la válvula de control de la boquilla se basa en un conocido efecto piezoeléctrico utilizado, por ejemplo, en los encendedores de gas. El dedo del hombre presiona un botón que deforma el componente de trabajo desde el dieléctrico. Como resultado, la carga utilizada para inflamar el gas.

En boquillas piezoeléctricas, t. N. Efecto piezoeléctrico inverso. El voltaje se alimenta a la dieléctrica, que contribuye a la deformación del material. La barra de la válvula está conectada a ella, que es capaz de escalar si la corriente se alimenta a la boquilla.
