Definitions

  • the invention relates to the automotive industry
  • Resistance to form is the main factor determining the value of the drag coefficient, which significantly affects the fuel efficiency of the car.
  • further significant reduction of this indicator due to optimization of the body shape without compromising the consumer qualities of the car seems an impossible task.
  • the main objective of the invention is to reduce the aerodynamic drag of a moving car in a thermodynamic manner, and not by changing the shape of the body.
  • the problem in the proposed method is solved by compressing the oncoming air flow in a narrowing duct in the front of the car, preferably using a fan of the engine cooling system or another blower to increase the degree of pressure increase in the duct, and then expanding the compressed air in the expanding rear
  • thermodynamic compression and expansion cycle of the working fluid which is known to be useless, in which, as you know, the compression work will be equal to the expansion work minus the inevitable losses, will reduce or eliminate pressure on the front of the car while driving, as well as reduce or eliminate the vacuum created behind part of the car.
  • the cooling system fan in addition to the main functions, will perform additional useful work of compressing the air in the duct, compensating for the inevitable losses during compression and expansion of the working fluid.
  • the system will work on the principle of a heat engine, in which heat energy will be supplied by mixing the working fluid compressed in the air duct with hot exhaust gases.
  • a vacuum is generated in the engine exhaust pipe connected to the duct, which will help to improve the evacuation of exhaust gases from the engine cylinders and increase engine efficiency.
  • FIG. 1 diagram of a device operating according to the specified method
  • the device contains the following main elements: duct 1, radiator of the engine cooling system 2, fan or supercharger 3, exhaust pipe of the engine 4, engine 5, filter 6.

Abstract

Le procédé thermodynamique pour réduire la traînée aérodynamique d'une automobile en mouvement comprend la compression adiabatique et la dilatation adiabatique du flux d'air arrivant de face. Le flux d'air arrivant de face est comprimé dans la partie rétrécissante avant d'une conduite d'air (1), avec ou sans compresseur (3). Pour augmenter l'efficacité, ce système de compression et de dilatation du flux d'air de face est regroupé avec le système d'échappement du véhicule. L'air comprimé et chauffé se dilate dans la partie arrière évasée de la conduite d'air (1) et est rejeté dans l'atmosphère.
