Abstract: An injection/mixing device (2) for improving the mixing of fuel and air in a petrol driven internal combustion engine. The device (2) is fitted in the engine inlet manifold (3) close to the fuel inlet from a carburettor or fuel injector (6) and uses a vortex generator. The vortex generator is in the form of an array of lenticular, conical or deltoid disks (22) located in the fuel/air flow and which serve to disperse the impinging fuel droplets and mix the fuel and air. The effect of the device is preferably enhanced by allowing the vortex generator to rotate or spin about its axis. This rotation is achieved by means of a turbine (40) associated with the disks or by means of an external motor. The device may also be connected to a vacuum relief valve (1) to attenuate the level of the depression in the intake manifold under certain conditions. The vacuum relief valve may be integral or separate from the device.

Abstract: The invention relates to a method and a device for atomising a liquid fuel during the supply thereof to a combustion chamber (10). According to the invention, a liquid fuel is mixed with a combustion-promoting gas and, in this context, set in high-frequency vibration, the mixture is conducted past an inwardly directed, peripheral edge (16) in said chamber, and a secondary flow of combustion-promoting gas is sucked into the chamber adjacent or immediately after this edge in an amount controlled by the negative pressure or vacuum in the chamber, when the negative pressure in the chamber is lower than a settable limit value. According to the invention, use is preferably made of a check valve (19) whose degree of opening varies depending on the prevalent negative pressure in the chamber and which is settable to a desired limit value.

Abstract: An automatic bleed valve is disclosed, suitable for attachment to the inlet manifold of an internal combustion engine in order to provide an effective embodiment of the 'air bleed' principle. Small amounts of inlet air are allowed into the inlet manifold at periods of high vacuum (low pressure) present during deceleration. The valve closure (38) is biassed by a biassing means (36), e.g. a compressing spring, which acts on the face of the closure disposed away from the seat (22). Other aspects provide for a valve seat which is adjustable in position relative to the closure, a closure and seat of different plastics materials, and a closure with a conical aspect, preferably paired with a seat with a complementary contact portion.

Abstract: Device which adjusts the combustion of engines during their operations in transitional phases, accelerations, decelerations and changes in the transmission ratios by reduction or suppression of the gas flow through the nozzles of the carburettor, and or by admission, downstream of the carburettor of additional air or exhaust gases, crank-case gases or a mixture of these gases. By its mode of action, the device acts during about75% of the running time of the vehicle in city traffic (case of the ECE 15 cycle). The different embodiments of the device are all characterized by the monitoring system (1-6) controlled by the admission pressure of the engine so that the direction, the intensity and the time of action of the power transmitted to the correcting member (7) be permanently depending on the value of the derivate of that admission pressure with respect to time (POWER = F ((dpa k)/dt) The device may be easily set on any vehicle as an economizer or incorporated in modem combustion systems, conventional or electronic.
