Abstract

Using engine building. SUMMARY OF THE INVENTION: a method of operating an internal combustion engine with shut-off cylinders consists in preparing a fuel-air mixture, regulating its supply to the cylinders depending on the load, sequentially supplying the fuel-air mixture to each shut-off cylinder with increasing load and they turn off part of the cylinders when the load is reduced, additional air is supplied to at least the cylinders to be switched off, and the air-fuel mixture is regulated si with a constant volume of air, additionally supplied to the cylinder. 2 s.p.

The invention relates to engine building.

It is an object of the invention to increase operational efficiency.

Figure 1 shows a diagram of the engine; nafig. 2-node air intake and fuel-mixture mixture.

The engine contains cylinders 1, 2, 3, A with pistons 5. connecting rods to the crankshaft, intake valves 6, exhaust valves 7, fuel line 8, air line 9 / air supply channel 10 in communication with air line 9, channel air-fuel mixture inlet 11, communicated through the fuel line 8 with the source of mixture formation

12. The inlet channel of the air-fuel mixture 11 is made in the form of a stationary nozzle 19 and installed inside the last spring-loaded movable nozzle 20, installed with the possibility of tight contact on the surface 21 of the intake valve 6. The spring-loaded rod 22 is made with a restrictive surface 24, interacting with the limiter 23, made on the surface of the movable pipe 20. In the central part of the pistons 5, recesses 25 are made. Device 13 for controlling the supply of the air-fuel mixture and sequential switching to work from disconnected cylinders made in the form of a rod 14 s

cams 15 having flat surfaces 16 and 17 and a conical surface 18. The surfaces 16, 17, 18 are configured to interact with the rods 22 /

The engine operates as follows.

When moving the rod 14 to the right, the rods 22 of the cylinders 1, 2, 3 interact with the flat surfaces 16, as a result of which, the movable nozzles 20 either shut off the air-fuel mixture, and either only air that is compressed, expands and is released through the cylinders exhaust valves 7, or a small amount of air-fuel mixture is constantly admitted p, providing idling.

The rod 22 of the cylinder 4 interacts with the conical surface 18, which makes it possible to adjust the load from idle to the most economical one by changing the displacement of the movable pipe 20. In the cylinder 4, a layered charge is formed at the inlet, which is ignited by the candles. To further increase the load, the rod 14 moves to the left, the rod 22 of the cylinder 4 interacts with a flat surface 17, providing maximum power. At this moment, the rod 22 of the next cylinder (for example, cylinder 3) interacts with the conical surface 8. Upon further movement of the rod 14 to the left, the following cylinders 2 and 1 are subsequently turned on.

The load is reduced by moving the rod 14 to the right, while the cylinders are taken out of operation in the reverse order. Figure 1 shows the position of the rods 22 providing the maximum flow of the air-fuel mixture into the cylinder 4, an intermediate value of the flow into the cylinder 3, and the absence of the flow of the air-fuel mixture in the cylinders 1 and 2.
