Description

The invention relates to the field of mechanical engineering and, in particular, to methods and devices for suctioning products of combustion from cylinders of an internal combustion engine.

The aim of the invention is to increase the efficiency of operation by improving gas exchange.

The drawing shows the scheme described engine internal combustion.

The engine for implementing the method contains at least one cylinder 1 with a piston 2, an exhaust gas exhaust body 3 with a residual gas exhaust body 4, a discharge pipe 5, an ejector 6, a water evaporator 7, a tank 8 and a water supply pump 9 from the tank 8 and an evaporator 7 „

The exhaust ductwork, ode 5, is connected to the body of 3 editions of the o-tragic gas

The water evaporator 7 is divided into water and steam cavities 13 and 14, the ejector 6 is made steam and connected by its active nozzle 10 to the vapor cavity of the evaporator 7 The exhaust gas outlet 3 is made in the form of a control valve installed in the upper part of the cylinder 1 "Intake organ made in the form of a controlled valve 15 "

The engine works as follows.

When piston 2 moves in cylinder 1 to the bottom dead center, fresh charge is supplied through inlet body 15. Then, when piston 2 moves to upper

dead To-iKe, the charge is compressed, and then the combustion of the air-fuel mixture and the combustion of the combustion products. After the expansion stroke, the removal of the 3 exhaust gases is opened and the exhaust gases are released from the cavity of the cylinder 1 to the exhaust pipe 5o. the piston 2 moves to the top dead center. After closing the organ 3, the residual gas suction organ A is opened and the residual gases are sucked out of the cavity of the cylinder 1 while it communicates with the pressure zone 12 when the piston 2 moves to the top th dead point The reduced pressure in zone 12 is maintained throughout the piston stroke to the upper dead point. For this purpose, water vapor produced by the evaporation of water by the heat of exhaust gases is used as the active medium for ejection.

In the water of the 1st cavity of the evaporator 13, water is supplied from the reservoir 8 by means of a feed pump 9; water formed in the steam cavity 14 is partially suctioned from the reduced pressure zone and in the exhaust pipe 5 and sucked off gases through the organ 4o The condensate formed in the ejector 6 Boitti is discharged into the reservoir 8o

Near the top dead center, the inlet organ 15 is opened and the suction organ 4 is closed, the cycle is repeated

Water can be used from the engine cooling system,.
