A fuel manifold for the direct injection of fuel into an internal combustion engine comprising a head provided with a number of cylinders, a number of injectors, each of which is connected to the fuel manifold and is adapted directly to inject the fuel into a respective cylinder, and an intake manifold, which is connected to the head in order to supply fresh air to the cylinders, the fuel manifold being formed by a single monolithic body which is made from thixotropic aluminum by means of a pressure die casting process and comprises a supply duct adapted to distribute the fuel to the injectors, and a flange disposed laterally to the supply duct, the flange being adapted to be secured by a plurality of screws to the head of the engine and comprising a number of coupling members each of which is adapted to bring a respective cylinder into communication with the intake manifold.

Method for producing salt grains in which the salt is dissolved in a liquid solvent inside a mixing tank so as to form a saline solution which is supersaturated with salt and which is then atomized inside a drying tower where a stream of hot air circulates; the atomizing process being designed to produce a plurality of drops of saline solution, all of approximately the same size, and the stream of hot air being designed to evaporate the liquid solvent contained in each drop so as to cause the salt present in the said drop to solidify into a salt grain of essentially spherical shape; given that the dimensions of the salt grains depend on the dimensions of the drops of saline solution, it is possible to obtain salt grains of the desired size by producing drops of saline solution of a suitable size during the atomizing process.

A method including a preheating stage wherein rheocast light alloy ingots are preheated to a temperature within the solidification range of the alloy; and a die casting stage wherein a mold is filled with the semiliquid alloy. The preheating stage is performed in a forced-convection-heated tunnel furnace, with the ingots housed inside cup-shaped containers which, following a temperature check, are tipped by a robot to unload the ingots into the injection chamber of a die casting machine. Work is conducted within a temperature range depending on the composition of the alloy, and such that, at the minimum permissible injection temperature, the ingot is incapable of maintaining its own shape, and, at the maximum permissible injection temperature, the apparent viscosity of the ingot is such as to ensure the mold is filled under laminar flow conditions.
