Inyectores Common Rail CRI y CRIN Conjunto Inyector CRS. Pre-inyección y inyección principal Para tener inyección, la bobina magnética del inyector recibe del módulo una frecuencia de picos de alta tensión eléctrica de ( 40 - 90 V) y la corriente eléctrica cerca de (10 -25 A ) amperios de acuerdo con la aplicación.
La responsabilidad de generar esos valores de tensión son de los condensadores que están dentro de la unidad de mando. La unidad de mando se sobrecalienta debido a la carga y descarga de los condensadores, por eso el módulo debe fijarse aun local que produce mejor refrigeración en el motor. Atención. Las personas que usan marcapasos no deben acercarse al motor. Automotive Aftermarket

Inyectores Common Rail CRI y CRIN Conjunto Inyector CRS. Pre-inyección y inyección principal Para tener inyección, la bobina magnética del inyector recibe del módulo una frecuencia de picos de alta tensión eléctrica de ( 40 - 90 V) y la corriente eléctrica cerca de (10 -25 A ) amperios de acuerdo con la aplicación.
La responsabilidad de generar esos valores de tensión son de los condensadores que están dentro de la unidad de mando. La unidad de mando se sobrecalienta debido a la carga y descarga de los condensadores, por eso el módulo debe fijarse aun local que produce mejor refrigeración en el motor. Atención. Las personas que usan marcapasos no deben acercarse al motor. Automotive Aftermarket
