When starting the engine, the control unit 18, based on signals from the air and engine temperature sensor 23, sends a signal to the fuel metering device 21 to set the required cyclic fuel supply to the cylinders 2. At the same time, a fresh charge is injected into the combustion chamber 6. each cylinder 2 of the engine through the intake port 12 opened by the piston 4 and simultaneous compression of the fresh charge in the above-piston cavity 5 of the cylinder 2 during the movement of the piston 4 to the upper dead center, ignition and combustion of the compressed charge in the above-piston cavity 5, expansion of the combustion gases, release of exhaust gases from the upper part 5 through the upper part 4 release of stage 11 and compression of the fresh charge in the thorn stone 6 by the back of the spine 4 and its movement towards the bottom meth point, then release a compressed fresh charge from ivory stone 6 into the top layer of cylinder 5 2 through Secondary channel 7 and external channel 4, intermediate channel 8, 10 blowing the piston cavity 5 with a fresh charge and removing the exhaust gases through the exhaust window 11 into the engine exhaust system. After starting the engine, based on the signal from the sensor 22, the control unit 18 sends a signal to the drives 16 of the axes 17 of the swing of the levers 14. The drives 16 move the axes 17 of the swing of the levers 14 along straight lines X-X' from point "a" to point "ϊ" (Fig. 7). In this case, the levers 14 shift the joints 15 of the articulated connecting rods 10 from the axis Y-Y' of the cylinders 2, thereby increasing the volume of the combustion chamber N c.s. (the volume of the above-piston cavity of the cylinders 2 with the position of the pistons 4 at the upper dead center). If the changed volume of the combustion chamber X 'k.s. will be consistent with the degree of compression of the fuel used and the detonation will be protected, block 18 of the control will go away Ensuring the engine operates at normal speed, by mimicking the signal, thereby introducing fresh charge into one of the 2 cylinders (modules) engine and stop the fuel supply to the remaining cylinders 2 (modules), and also send signals to the drives 16 of the axes 17 of the swing of the levers 14, along which the pistons 4 in the remaining cylinders 2 (modules) are stopped. To stop the pistons 4 for a specified time in the idle cylinders 2 (modules) with the rotating crankshaft 9, the control unit 18 sends signals to the drives 16, which move along the straight lines X-X' of the swing axis 17 of the levers 14, which in turn shift the hinges 15 articulated connecting rods 10 Y-U axes of cylinders 2 bearings of the crankshaft 9 in the lower area at the middle point and return the connecting rods 15 articulated connecting rods 10 to the axes of the cylinders 2 piston Let's get started There are a lot of spikes in the area from the upper point to the lower point. Pi duration 11 No. work on the cylinder, in order to maintain a stable thermal state of the engine, it is possible to alternate the operation of cylinders 2 (modules), namely, they stop the supply of fuel to the working cylinder 2 (module) and begin supplying fuel to one of the non-working 2 cylinders (modules). And this is how only a fresh charge reaches the 25 oxygen sensor in the exhaust system according to its signal from control unit 18 Mimics the feedback signal

Lever 14 shifts the joint 15 of the articulated connecting rod 10 to the axis Y-Y' of cylinder 2 for accelerated closing of the intake and exhaust ports 8.11 piston 4. Due to this, the loss of fresh charge is stopped (fuel) into the engine exhaust system, which helps to increase its fuel efficiency. In order to regulate the amount of fresh charge in the piston cavity 5 of cylinder 2, control unit 18 sends a signal to drive 16, which moves the swing axis 17 of lever 14 at a given speed for accelerating or slowing down the overlap of the bypass and release window 8,11 after a specified time interval, which ensures increased accuracy of dosing of fresh charge in the piston cavity 5 (Fig. 11,13). By changing the time of care 4 stages of inlet and outlet 8.11, we control the filling of the supraspinal 5 cylinder 2 with fresh charge, possible 0.5 to 1.8 οτ volume above piston face 5. When the engine is running at partial loads and the appearance of an increased concentration of nitrogen oxides in the exhaust system, based on the signal from the nitrogen oxide sensor 24, the control unit 18 sends a signal to the drive 16, which increases the speed of the feed 12 displacement of the axis 17 of the swing of the lever 14 and the speed of movement of the piston 4 when the bypass and exhaust windows 8.11 are overlapped, thereby increasing the amount of exhaust gases mixed with the fresh charge in the above-piston cavity 5, which reduces the maximum cycle temperature and toxicity of the exhaust gases.

According to the light load block 18 control formats send signals that set the working volume of the piston cavity 5 of cylinders 2, the cyclic fuel supply to cylinders 2 and the number of working cylinders 2. In order to change the working volume of the piston cavity 5 of cylinder 2 and the compression ratio, the position of the dead ends is changed the point and stroke of the piston 4 by moving the axis 17 of the swing arm 14 and shifting the joint 15 of the articulated connecting rod 10 under the action of the drive 16 (Fig. 7-12). In modes close to the nominal one, control unit 18 simulates signals that switch sensors 24.25 oxides nitrogen and acid, increasing the supply of fresh charge to the overhead lobes of 5 cylinders 2 and mixing Exhausted gases with fresh charge by using a longer blowing time.

The present invention can be used in the design and production of two-stroke multi-fuel internal combustion engines with a blood-chamber blower. The proposed two-stroke engine and the method of its operation can be used in all transport stations and stations. installations, in which there are increased concerns about the dimensions of power installations, as well as on motorcycles, snow, luxury boats, scooters, small cars. The engine can be installed on high-capacity vehicles where it can be used increased fuel economy, since this type often works with disadvantages and this part cylinders (modules) could have switched on temporarily. The engine can also be used on helicopters, airplanes, various utility vehicles: excavators, Channels and the like, as well as larger ships.
