    Abstract: A device which, when an engine is not yet running at a steady temperature, provides for the regulation of fuel-air ratio as a function of the engine temperature but independently of the flow rate of the air aspirated by the engine, by means of additional throttling means, upstream of the main throttling means. The additional throttling means are controlled by a device sensitive to the temperature of the running engine, so as to correspondingly adjust the density of the air aspirated by the engine only as a function of the engine temperature.

    Abstract: A regulation device is disclosed, for regulating a physical magnitude as a function of two independent parameters: the parameters can be, for example, parameters of interest in the operation of an internal-combustion engine. Instead of the conventional space cam, a surface is provided on which the third dimension is represented by different voltage so as to define on such a planar or curved surface a family of equipotential curves. The readings taken by a conductive follower are mechanically converted so as to govern the appropriate component parts of an engine so as to have an automatical adjustment of certain parameters. The device is dependable and reliable and cannot be prone to jamming or mechanical defects. The device is of the potentiometric class.

    Abstract: An exhaust conveying system for internal combustion engines, in which the exhaust pipes connecting the engine head with a single exhaust manifold comprise each at least a pair of tubular members, at least one of the tubular members being made of thin sheet having circumferential corrugations, with the crests of the corrugations being adherent to the surface of the other tubular member so as to define air spaces between the tubular members. As consequence, the heat losses from the exhaust pipes are strongly reduced, thus improving the post-combustion of unburned components of the exhaust gases which takes place downstream of the exhaust pipes. The exhaust pipes can also be provided with a porous layer of a ceramic material bonded to their inner wall.
