The technical field

The invention relates to the field of engineering.

The level of technology

Energy is compressed in the cylinder of the internal combustion engine (hereinafter - ice) of the working fluid is air or a fuel mixture depending on the type of engine is on the compression stroke can be directly used to drive a variety of mechanisms, for example, the timing mechanism of the engine, the patent 2403409, or drive the fuel injector, the patent 2392482 - closest analogues of the claimed invention.

The principle of operation of the drive air compressor gases from the cylinder internal combustion engine is illustrated on the basis of a patent 2403409 "Valve-shutoff pneumatic timing mechanism of an internal combustion engine".

The piston of the internal combustion engine 1 during the compression stroke compresses the working fluid is air or fuel mixture in the combustion chamber 2. In this part of the working fluid from the combustion chamber 2 through the pipe 3, through the automatic valve shutoff 4 and the check valve 5 flows into pneumotachometer 6 and charge it. The electronic control system of internal combustion engine pneumatic actuator gas valve (hereinafter control system, not shown) monitors the current position of the piston internal combustion engine 1 and, at the time when you want to open gas valve 7, sets Zolot the 8 position, as shown in the drawing. The working body of pneumotachometer 6 channels 9 and 10 enters the upper chamber of the piston valve actuator 11, resulting in a gas distribution valve 7, if it is the intake that allows air from the atmosphere through the channel 12 to flow into the combustion chamber 2, or if it is the exhaust, flow of products of combustion from the combustion chamber 2. To close the gas valve 7, the control system sets the spool 8 in the lower position, and the working fluid from pneumotachometer 6 channels 9 and 13 enters the lower cavity of the piston of the actuator 11, and the gas distribution valve 7 is closed. In both cases, the spent working fluid through the channels 10, 13, 14, 15 is discharged into the atmosphere, but gasoline engine where the working fluid is a fuel mixture, for reasons of economy of fuel fed into the intake tract of the engine.

It should be borne in mind that the charging pneumotachometer occurs not only during the compression stroke of the working fluid in the combustion chamber, as shown in the above-mentioned similar, but during the cycle of expansion of the exhaust gas when the pressure in the combustion chamber can reach hundreds of atmospheres, and the temperature of hundreds of degrees. But to ensure the health of the pneumatic actuator is sufficient pressure of the working fluid on the order of or even less. The limit pressure, the working fluid in pneumotachometer to the optimal value provides an automatic valve shutoff 4. If the pressure is coming from the combustion chamber 2 of the working fluid is less than optimal, it passes through the valve cutoff 4 in pneumotachometer 6. When the pressure of the working fluid in pneumotachometer 6 above the optimal working fluid through the channel 16 enters the lower cavity of the piston valve 17 is cut-off. Under its influence, the piston valve cutoff 17 and connected with it shutoff valve 18 is moved up and channel 19 is blocked. The charging level pneumotachometer 6 working fluid is determined by the stiffness of the spring 20.

The greater the stiffness of the spring, the up to a higher level of charge of pneumotachometer. Energy is compressed in the cylinder of the working fluid is air or a fuel mixture depending on the type of engine is on the compression stroke is directly used to drive a variety of mechanisms, for example, the timing mechanism or actuator of the fuel injector. However, there is a probability of ignition of the fuel mixture for gasoline internal combustion engines in pneumotachometer and gas mains drive.

The purpose of the invention is to unify pneumatic actuator so that it was suitable for all types of internal combustion engines.

The invention

Compressor charging method of pneumotachometer pneumatic actuator gas valve and fuel injector engine atmosphere the m air is the following.

Figure 2 presents the scheme of the drive air compressor ambient air gases from the cylinder of the internal combustion engine.

The piston of internal combustion engine 1 on the compression stroke compresses the working fluid is air or fuel mixture in the combustion chamber 2 and compressible working fluid pressure on the left side of the piston of the compressor 3, causing the piston of the compressor 3 is moving to the right (drawing). Compressible located right in the compressor cavity of the piston of the air compressor 3 through the check valve 4 flows into pneumotachometer 5. Full charge of pneumotachometer 5 occurs when starting the engine for one or more cycles of compression in the combustion chamber 2 of the working fluid, and recharging is only for one cycle. On a cycle of intake air into the combustion chamber 2, the air pressure therein decreases, the spring compressor 6 moves the piston of the compressor 3 to the left and the air from the atmosphere through the check valve 7 is sucked in his right compressor cavity. Simultaneously, the electronic control system of internal combustion engine monitors the current position of the piston internal combustion engine 1 and, at the time when you want to open gas valve 8, sets the spool 9 in the position as shown in the drawing. Compressed air from pneumotachometer 5 channels 10 and 11 flows into the upper chamber of the piston valve actuator 12. Under its action, naturally clap the n 8, if it is the intake that allows air from the atmosphere through the channel 13 to flow into the combustion chamber 2, or if it is the exhaust, leak into the atmosphere by the combustion product from the combustion chamber 2. To close the gas valve 8, the control system sets the spool 9 in the lower position, and the air from pneumotachometer 5 channels 10 and 14 enters the lower cavity of the piston of the timing valve 12, and the gas distribution valve 8 is closed. In both cases, the spent air through the channels 11, 15 and 14, 16 is discharged into the atmosphere. As soon as the pressure in pneumotachometer 5 reaches the optimal value, ensuring optimal functioning of the actuator gas valve and the fuel injector, the air from pneumotachometer 5 channel 17 enters the lower cavity of the piston mechanism of the stopper 18 of the piston of the compressor 3. The piston mechanism of the stopper 18 is moved up and stoparic the piston of the compressor 3 in position as shown on the drawing or in the position as shown in the schema fragment below the base schema. The admission of compressed air into pneumotachometer 5 stops. The charging level pneumotachometer 5 is determined by the spring stiffness of the piston of the compressor 6. The greater the stiffness of the spring, the up to a higher level of charge of pneumotachometer 5. Channel 19 is legit for ventilation of the middle cavity of the piston of the compressor 3.

Thus, the claimed method of charging pneumotachometer provides performance pneumatic actuator gas valve and fuel injector atmospheric air, all types of internal combustion engines.
