    摘要： A carburetor for spark-ignition internal combustion engines, comprising a plurality of chokes formed in a body and cooperating with a shutter which is displaceable perpendicularly to the axis of the chokes and has passage openings so shaped and arranged as to uncover the chokes in sequence, so that, in the various operating conditions, all the active chokes operate at their full opening excepting only the last which may be partially shut. The result is a greater efficiency, a better combustion and a reduction of the exhaust gas pollution. In the preferred embodiment, the chokes are arranged along circle arcs, and the shutter is a rotating disc having arcuate openings, located between the body wherein the chokes are formed and an underlying distributor. The various chokes may be differently sized and provided with different nozzles in order to obtain the best metering in the various operating conditions. Also the shutter openings may be so profiled as to obtain a desired variation law of the carburetor openings.

    摘要： Carburetor for gasoline engine has connecting air-intake and gas mixture chambers separated by an adjustable, air-metering valve provided with throttle opening means of variable flow area and communicating with said connecting chambers for providing venturi effect. Gas metering member in gas mixture chamber adjustable with movement of valve to vary amount of gas globules metered out to mix with air throttled through the opening means in valve, according to demand of engine. Efficiency of carburetion improved by controlled suction of air at any given throttle opening, for combination with likewise controlled flow of gas globules, in a proportion with reference to said venturi effect which provides maximum power and performance efficiency at any given engine speed, while accomplishing substantially complete atomization of the gas globules at all engine speeds.

    摘要： The invention relates to a method and a device for automatically starting an internal combustion engine having a brake pressure monitoring system and a means of evaluating the brake pressure with respect to its profile over time. The brake pressure gradient is evaluated when the brake pedal is released before the vehicle is restarted. If the absolute value of the negative brake pressure gradient when the brakes are released exceeds a threshold value, this upward transgression of the threshold value causes an electronic control system in the motor vehicle to restart the internal combustion engine in conjunction with a start/stop function. The main advantage which is achieved in this way is that the brake pressure gradient precedes the point at which the brake pressure reaches its position of rest so that a vehicle driver can sense the restarting of the internal combustion engine to be more spontaneous than in the prior art. With the solution according to the invention for restarting the internal combustion engine a longer period of time is available than with previously known solutions.
