ABSTRACT:
A fuel rail in a variable intake module is integrated, thereby obtaining a sufficient coupling area and excellent sealing between the variable intake module and intake manifold. The assembly of injector and variable intake module to an engine is improved. A high pressure fuel path is integrally formed at a lower inner side of the variable intake module, wherein the variable intake module includes a plurality of intake paths and a flap placed at each intake path to form a tumble. Furthermore, an injector insertion part is formed at a lower side of each intake path to communicate with the high pressure fuel path.
