  • the described device can help increase the power of the internal combustion engine of the vehicle — the car, but this increase is not effective enough due to the body of the car creating additional interference with the incoming air flow, which impairs ventilation in the cylinders of the internal combustion engine of the vehicle. This is especially noticeable when you need a significant increase in power at the beginning of movement and at speeds less than 30-40 kilometers per hour.
  • the basis of the invention is the task of developing such a device for creating exhaust gas traction in the exhaust system of an internal combustion engine of a vehicle, which would be more effective by creating conditions for forced rarefaction the exhaust gases in the exhaust pipe of the vehicle’s internal combustion engine and would not depend on the speed of the air flow incident on the vehicle, which, as a result, would increase the exhaust gas thrust in the exhaust pipe and improve the ventilation of the engine cylinders during its operation in different modes.
  • the proposed device for generating exhaust gas thrust in the exhaust pipe of an internal combustion engine of a vehicle is made in the form of a jet ejector, which includes an electric air turbine, the input of which is designed to connect with the surrounding atmosphere, and a nozzle is installed at the output of the air turbine for its placement in the cavity of the exhaust pipe with the possibility of mixing the flow of exhaust gases and air from an air turbine.

  • the nozzle installed at the outlet of the ejector is designed to increase the speed of the active (ejection) stream, aimed at mixing with a passive stream.
  • the proposed device is more efficient than the prototype device, because it creates conditions for forced rarefaction of exhaust gases in the exhaust pipe of an internal combustion engine of a vehicle, which is aimed at increasing the draft of exhaust gases in the exhaust pipe and improving ventilation of the engine cylinders, which operates at low revolutions.
  • the presence in the device of an air turbine with an electric drive controlled by the corresponding system allows the driver of the vehicle to receive increased power during engine operation, which increases road safety.

Due to the forced continuous rarefaction of the exhaust gases in the exhaust pipe, the cylinders are better filled with fresh fuel-air mixture, which is equivalent to an increase in boost pressure and, as a result, increases the exhaust gas draft in the exhaust pipe and improves the ventilation of the engine cylinders during its operation at different modes .

Abstract

L'invention se rapporte aux éléments structurels de moyens de transport, et concerne notamment un dispositif de génération de poussée à partir des gaz usés dans le pot d'échappement d'un moteur à combustion interne d'un moyen de transport. Le dispositif de l'invention se présente sous forme d'un éjecteur à flux comprenant une turbine à air avec un actionneur électrique dont l'entrée est reliée à l'atmosphère environnante, tandis que la sortie de la turbine à air comporte une buse venant se loger dans la cavité du pot d'échappement de manière à mélanger les flux de gaz d'échappement et l'air sortant de la turbine à air. Le but de la présente invention est d'élaborer un dispositif qui soit efficace grâce à la création de conditions de raréfaction forcée des gaz usés dans le pot d'échappement du moteur à combustion interne du moyen de transport et qui ne dépende pas de la vitesse d'écoulement du flux d'air sur le moyen de transport de sorte qu'en conséquence il permette d'augmenter la poussée des gaz usés dans le pot d'échappement et d'améliorer la ventilation des cylindres du moteur lors de son fonctionnement à bas régime.
