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.
The RUDN University Science and Innovation Prize winners were honoured at the extended meeting of the Academic Council. In 2024 the terms of the traditional RUDN University Prize were changed: for the first time the competition was announced in two categories: leading scientists and young scientists.
According to the International Energy Agency (IEA), electricity consumption in Africa has increased by more than 100% over the past two years (2020-2022). However, 74.9% of this energy is still produced by burning organic fuels — natural gas, coal and oil. At the same time, the level of electrification on the continent remains extremely low — only 24%, while in other developing countries it reaches 40%. Even in grid-connected areas, electricity supply is often unreliable: industrial enterprises lose energy on an average of 56 days a year.
Today, diagnosis and treatment planning with orthodontists takes several days. Also, complications can arise during treatment that slow down the patient's recovery process. For example, improper orthodontic treatment planning can lead to temporomandibular joint dysfunction.
