 Information confirming the possibility of carrying out the invention.

The two-stroke internal combustion engine shown in FIG. 1-6, contains a cylinder block 1 ^x , the outer heads 3, 4 mounted on the sides of the cylinder 5 (see Fig. 1, 2).

 Pistons 1-2, located in volumes 1 '' - 2 '' of cylinder 5, are mounted on shaft 6 with the possibility of reciprocating motion (see Figs. 1, 2).

 The shaft 6 is located on the axis 7 of the cylinder 5 in the holes of the bearings 8 with the possibility of rotational motion (see Fig. 1, 2).

 Moreover, the pistons 1-2 contain a sealing belt 9 of the rings 10 for sealing the pistons 1-2 with the cylinder 5 (see Fig. 1, 2).

 The engine contains a rod 11 located in the holes of the pistons 1-2 and fixed by the ends in the heads 3, 4 (see Fig. 1, 2).

 Pistons 1-2 in the sealing belt 12 of the rings 13 in the socket 14 and in the diagonal groove 15 contain a roller 16, which translates the reciprocating movement of the pistons 1-2 into the rotational movement of the shaft 6 with the flywheel 17 (see Fig. 1-6) .

 Pistons 1-2 also contain a sealing belt 18 from rings 19 for sealing pistons 1-2 with a rod 11 (see Fig. 1, 2).

 And also the pistons 1-2 contain a sealing belt 12 of the rings 13 for sealing the pistons 1-2 with the shaft 6 (see Fig. 1-6).

 And the pistons 1-2 in the sealing belt 12 of the rings 13 in the annular grooves 20 and in the diagonal grooves 15 on the shaft 6 contain rollers 21 for sealing the pistons 1-2 with diagonal grooves 15 on the shaft 6 (see Fig. 1-6).

 Two-stroke diesel engine operates as follows.

 If we accept the alternation of clock cycles in a single-cylinder diesel engine with two working volumes in the cylinder with the operating procedure in working volumes 1 '' - 2 '', then in the first volume of the cylinder the stroke and inlet will take place, in the second - blowing and compression.

 In this case, the pistons 1-2 in the volumes 1 '' - 2 '' of the cylinder 5 are moved from the top dead center (TDC) to the bottom dead center (BDC).

 At the end of the working stroke in the first volume of 1 '' cylinder 5, pistons 1-2 move in their volumes 1 '' - 2 '' from BDC to TDC.

 The diesel workflow takes place in one flywheel revolution.

 A two-stroke carburetor engine operates as follows.

 If we take the alternation of cycles in a single-cylinder carburetor engine with two working volumes in the cylinder with the working order in working volumes of 1 '' - 2 '', then in the first volume of the cylinder the working stroke and intake of the combustible mixture will occur, and in the second - compression and ignition of the working mixtures.

 In this case, the pistons 1-2 in the volumes 1 '' - 2 '' of the cylinder 5 are moved from the top dead center (TDC) to the bottom dead center (BDC).

 At the end of the working stroke in the first volume 1 '' of cylinder 5 and the beginning of the working stroke in the second volume 2 '' of cylinder 5, pistons 1-2 move in their volumes 1 '' - 2 '' from BDC to TDC.

 The working process of a two-stroke carburetor engine is performed in one revolution of the flywheel.
