Description

 The invention relates to internal combustion engines (ICE) and compressor units.

 There is a known desire to use ICE as a device for producing compressed gases, the energy of which is used in parallel with the selection of power of the crankshaft of the engine to drive various mechanisms. A device is known from the patent literature, which is the closest analogue of the claimed invention, including a receiver in communication with the consumer, and an internal combustion engine containing cylinders with compression chambers (see RU 2101565 A, 10.01.1997). In the known device it is noted that the implementation of the known device will dispense with the compressors installed on the engines.

 However, the known device has a drawback consisting in the technical complexity of the design solution.

 The objective of the invention is to use the internal combustion engine and as a device "compressor", providing the accumulation of compressed gas through the selection of engine power from the crankshaft and the use of energy of compressed gases accumulated in the receiver.

 The technical result is achieved in that in a motor compressor including a receiver in communication with the consumer and an internal combustion engine comprising cylinders with compression chambers, at least one compression chamber of the internal combustion engine is connected to the receiver through a channel with a valve configured to adjustments to the required pressure. The solution to the problem is greatly simplified if the working fluid in the organized pneumatic system receives gas generated as a result of combustion of the air-fuel mixture in the cylinders of the engines. In addition, the use of exhaust gases makes it possible to accumulate them in a high degree of compression, which is very important, and in conventional compressor installations their multistage is achieved.

 The invention is illustrated in the drawing, which shows a possible diagram of the use of ICE to produce compressed gas.

 The diagram shows the engine ICE 1 with a piston 2 located in the cylinder 3, the compression chamber of which is connected through a channel with the receiver 5, communicated with the consumer. In said channel 4 there is a valve 6, made with the possibility of adjustment to the required pressure. Valve 6 is set to a pressure higher than the compression pressure of the engine (compression ratio).

 The motor compressor according to this scheme works as follows. With the approach of the piston 2 to the top dead center of the internal combustion engine (carburetor, diesel or any other), the air-fuel mixture is compressed and ignited at a certain point. A valve set to a pressure higher than the compression pressure of this engine opens. Gas flows through the open channel 4 into the receiver 5 and simultaneously pushes the piston 2. At the initial moment, gas will enter the receiver 5 until the pressure in the cylinder 3 reaches the response value of valve 6. The remaining energy of the compressed gas will be spent on cranking the crankshaft engine. In the future, if there is no gas consumption from receiver 5, the shutdown of valve 6 will be the earlier, the greater the pressure in the receiver. When the receiver reaches a pressure that is different from the pressure in the combustion chamber of the internal combustion engine at the time of the flash by the value of the valve 6 setting, the engine starts to operate normally (only on the crankshaft). With the consumption of gas from the receiver 5, the valve 6 opens and restores the pressure in the receiver 5.

 Thus, the installation of an additional valve (s) in the cylinder (s) of the internal combustion engine enables the engine to be used as a compressor installation, i.e., it is possible to take engine power from the crankshaft and by using the energy of compressed gases accumulated in the receiver.
