Device for regulating the composition of the combustible mixture supplied by the carburetor

(Oschepkov P. P., Kamyshnikov R.O., Mirolyubov V. I., Novikov V.A., Kamyshnikov O. V., Konoplev V. N.)

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 Chemist: Algae Can Both Purify Lead-contaminated Water and Create Biofuel

Lead is one of the most common heavy metals that pollute the environment. The level of lead pollution is constantly growing because of its use in the production of batteries, paints, and fuel. Basically, lead enters the environment through the wastewater of production facilities. From there, it affects the entire ecosystem. One of the ways to purify water from lead is bioremediation. Toxic metal is absorbed by microorganisms that become resistant to it, for example, through increased accumulation of lipids. RUDN University chemist together with colleagues investigated the possibility of using microalgae Chlorella Sorokiniana for bioremediation. Chemists have also shown that the protective mechanisms of algae not only reduce the level of pollution, but also increase the potential of using microorganisms as biofuels.
