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.
A RUDN chemist has synthesized an electrocatalyst based on gold nanoparticles with organic ligands, which can trigger both hydrogen production reactions and oxygen reduction reactions in fuel cells. The yield of products with the new catalyst was twice as high as when using a traditional platinum-based catalyst.
A chemist from RUDN University has proposed a new way to control toluene photooxidation using composite catalysts — artificial diamond and titanium dioxide. The discovery refutes the previously existing physical hypothesis about the process of photooxidation of toluene.
A RUDN University biologist has developed a model for the analysis of photosynthesis in vivo. This method allows you to calculate the absorption coefficient of light by chlorophyll, based on its reflectivity. Analysis of light absorption is important for assessing ecosystem productivity, which affects the state of the biosphere and the global climate.
