Device for regulating the composition of the combustible mixture supplied by the carburetor
This utility model relates to mechanical engineering, namely to the adjusting devices of the working processes of internal combustion engines with spark ignition. A device for regulating the composition of the combustible mixture consists of an electronic control unit associated with a source of pressure and vacuum. The pressure sensor is installed in the receiver. The device also contains a block of dampers, the inlet of which is connected to a source of pressure and vacuum, and the outlet is connected to a receiver. The output of the receiver through the pipeline is connected to the carburetor float chamber. Each flap in the flap block is connected to a stepper motor, controlled by an electronic control unit. Additionally installed pressure sensors located in the pipeline between each valve of the valve block and a source of pressure and vacuum, while additional pressure sensors are connected to the electronic control unit. The utility model improves the accuracy of adjusting the composition of the mixture over the entire range of engine load variation.
RUDN University mathematician together with colleagues from India and France for the first time studied in detail the system of coexistence of three species of living creatures in the wild. The results help to understand what parameters determine the extinction andли survivalof species, and how the number of species changes in space and time.
RUDN University chemist with his colleagues from Portugal has developed two types of coating based on new coordination polymers with silver. Both compounds were successfully tested against four common pathogens.
RUDN researchers have created and tested a method for processing titanium dental implants. It turned out that theanoslos of graphene on the surface of titanium improve its interaction with stem cells,which are placed on the implant so that it better "takes root".Thanks to this method ofprocessing, stem cells are better kept on the surface, multiply and turn into the desired cells.
