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 mathematicians have solved the problem of trajectory optimization for spacecraft with EPS. They determined the maximum possible useful spacecraft mass and optimum characteristics of the propulsion system, the most suitable for each of the considered missions.
RUDN University mathematician proposed a method for calculating the optimal trajectory of spacecraft with electric propulsion, whose thrust is thousands times less than chemical one has, but it is able to work for years. These motors are best suited for interplanetary missions. Mathematicians calculated the flight parameters of the space probe with such motor to Mars and Mercury. The paper is published in the journal Cosmic Research.
RUDN University chemists have discovered a unique method for making plastic film based on natural polysaccharides. It simultaneously has antioxidant, antimicrobial and barrier properties, and protects the content against ultraviolet exposure. Using the film to package and coat food products will considerably extend their shelf life.
