Central injection device for internal combustion engines

TLDR
In this paper, the annular gap was used to enrich the fuel-air mixture at higher loads by adjusting the opening of the pressure chamber such that the dynamic pressure is smaller than the leak pressure to numbers corresponding turns of the higher rotor for the rotor.
Abstract
The annular gap (20) for sealing the rotor (14) of the device and extends around a pin (8) for feeding fuel is connected through a ball bearing (7) to a pressure chamber (40) for the intake air. When the rotor (14) is driven by the impeller (31, 38), the dynamic pressure acting in the annular gap is opposite to the leak pressure. By adapting the opening of the pressure chamber (40) adjusting the dynamic pressure to a value equal or slightly higher than that in the manner that the fuel leakage pressure can escape through the annular gap (20). Order to enrich the fuel-air mixture at higher loads is chosen an opening of the pressure chamber (40) such that the dynamic pressure is smaller than the leak pressure to numbers corresponding turns of the higher rotor for the rotor (14) delivers additional fuel. A vent conduit (42) connects the pressure chamber (40) with the annular chamber (33) which causes the fuel from its inlet (16) to a spray ring (35) disposed below the blades ( 38). This ventilation provides uninterrupted fuel flow in the annular chamber (33). This injection device provides a fuel-air mixture in which the harmful substances of the exhaust gases are below the limit values, without the appearance of peaks of the upper limit values.

Controlled mixture formation

Beat A. Frei
TL;DR: In this article, a rotary distribution cup driven by its own motor is used to produce homogeneous mixtures with a freely selectable composition, with metered quantities of fuel being supplied to the pre-chamber via a feed pipe extending through a metering valve in such a way that the composition of the mixture produced in each case can be adjusted, irrespective of the amount of the air.

Turbine rotor assembly for a rotor-type carburetor

TL;DR: An injection molded plastic turbine rotor for a rotor-type carburetor is assembled by simply pressing together upper and lower generally cylindrical sections, and when joined in this manner the two sections form in the assembled rotor an internal circumferential seal between the two parts, and an internal passageway system which defines a centrifugal pump mechanism within the turbine rotor as mentioned in this paper.
