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.
On October 4, the Research and Educational Resource Center (REC) of innovative technologies of immunophenotyping, digital spatial profiling and ultrastructural analysis (molecular morphology) opened at the RUDN.
RUDN University scientists conducted a comprehensive soil and environmental survey and took more than 80 soil samples in Zaryadye Park. An assessment of the physicochemical, microbiological, and ecotoxicological properties of soils made it possible to develop recommendations and a plan for the care of soils in analogous landscapes in the park.
RUDN University chemist with colleagues from India and Korea created a nanofilter for water purification from synthetic dyes. The graphene-based composite can quickly remove up to 100% of harmful compounds from water, and it can be used up to seven times without losing efficiency. In addition, the synthesis of the nanofilter itself is economical and environmentally friendly.
