Abstract (en)

The present invention relates to a primary fuel rail (10) of the return-less type equipped with a particular axial heater device layout to increase the heat flux homogeneity in the fuel rail for an Ethanol Cold Start (ECS) system. The fuel rail (10) has one or more heating elements (12a, 12b) inserted therein in such a way that the heating part (100) of each element is oriented along or parallel to the main symmetry axis of the principal cavity of the said fuel rail (10) and each heating element is composed of two parts, an inactive support part (101) and an active heating part (100) having lengths (La, X), which can be individually tuned to obtain a maximum homogeneity of the heat flux along the rail towards the fuel injectors (11a-11d).
