Abstract

The invention relates to mechanical engineering and allows for increased efficiency. Air is injected into the intake manifold of the piston engine 1. A combustible mixture is prepared and the cylinders are filled with this mixture. The combustible death is ignited in the cylinders AND. The expansion work is used to drive the vehicle. Alternately, periodically release the exhaust gases from the cylinders into the chamber 3. mixing. In the additional channel of chamber 3, a rarefaction wave is created, which propagates through exhaust pipe 10 to combustion chamber 5 and further to inlet port 6. At the external section of the latter, the expansion wave is reflected by a compression wave, which fills the chamber 5 combustible mixture. The moment of arrival of the wave in chamber 5 is recorded by a pressure sensor 7 connected to the spark plug 9. The combustible mixture is burned, gases are fed under pressure into chamber 3, and the exhaust gases are drawn from the piston engine cylinders. Confu. Diffusion diffuser is used to increase thrust. 2 sec. and 1 z. p. f-ly, 2 ill. (About c /)

pipe installed on the exhaust pipe.

The vehicle power plant contains a piston engine 1 of internal combustion with an intake pipe (not shown) connected to cylinders (not shown) of the engine, an outlet pipe 2 with an ejector mixing chamber 3 installed in it and docked with the propulsor 4. The installation also contains a pulsating jet engine consisting of a combustion chamber 5 equipped with an inlet manifold 6, in which means for forming a combustible mixture, made in the form of a carburetor (not shown), are installed; Neither the inlet valve 8, a spark plug 9 connected to a current source (not shown) through a switch (not shown). The combustion chamber 5 is connected to the auxiliary input of the mixing chamber 3 by means of an exhaust pipe 10. At the end of the exhaust end of the exhaust pipe

Yes 2 installed with a gap confused diffuser pipe 11.

The installation works as follows.

Air is injected into the intake manifold of the piston engine I of the internal combustion and the fuel is prepared. mixture and filled with this mixture cylinders. The combustible mixture in the cylinders is ignited and the expansion operation is used to drive the vehicle. Alternately, periodically discharge the exhaust gases from the cylinders into the mixing chamber 3. In this case, in the additional channel of the mixing chamber 3, a discharge wave is generated, which propagates through the exhaust pipe 10 to the combustion chamber 5 and further

carburetor. The moment of arrival of the wave in the combustion chamber 5 is recorded by the pressure sensor 7 connected to the breaker of the ignition plug 9. The combustible mixture is burned, gases are fed under pressure into the mixing chamber 3 of the ejector, and the exhaust gases are additionally exhausted from the cylinders of the piston engine 1. At the same time, the confusion diffuser nozzle 11 serves to increase the thrust.
