1, the pneumatic generating system 1 includes an air compressor 2, an air dryer 3, an air tank 4, an air line 6, 7-1, 7-2, 8-1, 2, and blow lines 9-1, 9-2 as system components, and the first, third and third solenoid valves 5-1, 5-2, 5-3, the controller 20, And the map 20-1 as a system control element. In particular, the pneumatic generating system 1 comprises an oil separator for filtering the oil contained in the hot and humid inlet air generated in the air compressor, a pressure sensor for detecting the pressure of the air tank 4, A temperature and humidity sensor for detecting the amount of humid air in the compressed air, and the like.

Specifically, the functions of the system components are as follows.

The air compressor 2 is rotated in engagement with the engine gear to generate high-pressure compressed air. The air dryer 3 removes foreign matter (oil, moisture, imulsion) contained in the hot and humid air, and converts the air into a clean dry air state. The air tank 4 has a plurality of valves for storing compressed air in a clean dry air state through an air dryer 3 and providing compressed air as a power source to an operating pneumatic system.

The air lines 6, 7-1, 7-2, 8-1, and 8-2 are connected to the cooling pipe 6, the air filling pipe 7-1, the air branch pipe 7-2, (8-1), and an air discharge pipe (8-2).

For example, the cooling pipe 6 connects the air compressor 2 and the air dryer 3 so as to realize a dehumidifying operation and a heat radiating operation. The dehumidifying action removes the moisture of the compressed air of high temperature and high humidity, and the heat radiation action lowers the temperature of the hot and humid compressed air to 65 ° C or less, which is the inlet temperature of the air dryer 3. Therefore, the entire length of the cooling pipe 6 is set to a specific length at which the compressed air at 65 ° C or more from the outlet of the air compressor 2 can be dropped into the compressed air at 65 ° C or less at the inlet of the air dryer 3.

For example, the air filling pipe 7-1 leads from the outlet of the air dryer 3 to the inlet of the air tank 4 so that compressed air in the clean dry air state is stored in the air tank 4. The air branch pipe 7-2 connects the air fill pipe 7-1 and the air supply pipe 8-1. The air supply pipe 8-1 is connected to the first branch solenoid valve 5-1 and the second solenoid valve 5-2 in a state of being connected to the air branch pipe 7-2, Thereby forming a bypass path through which compressed air is supplied to the first and third solenoid valves 5-1 and 5-2. The air discharge pipe 8-2 is branched from the cooling pipe 6 and connected to the third solenoid valve 5-3 so that the high temperature and high humidity compressed air from the outlet of the air compressor 2 is discharged to the atmosphere. Thereby forming a path. The blow lines 9-1 and 9-2 are divided into a first blow line 9-1 and a second blow line 9-2. For example, the first blow line 9-1 connects the first blow port of the first solenoid valve 5-1 and the air compressor 2, and the second blow line 9-1 connects the first blow port of the first solenoid valve 5-1 to the air compressor 2. [ 2 Connect the second blow port of the solenoid valve (5-2) to the air compressor (2).

Specifically, the functions of the system control element are as follows.

The first solenoid valve 5-1 is connected to one end of the air supply pipe 8-1 and is connected to an air port which is turned on and off by the control of the controller 20, And a first blowing port connected to the first blowing line 9-1 for discharging the compressed air, which is opened / closed under the control of the controller 20. The second solenoid valve 5-2 is connected to the other end of the air supply pipe 8-1 through an air port which is turned on and off under the control of the controller 20, And a second blowing port connected to the second blowing line 9-2 for discharging the supplied compressed air and opened / closed under the control of the controller 20. The third solenoid valve 5-3 has an inlet port to which the air discharge pipe 8-2 is connected and a discharge port which is communicated with the atmosphere and is controlled by the controller 20 such that each of the inlet / OFF. Particularly, the first and second solenoid valves 5-1 and 5-2 apply an on / off valve type, and the third solenoid valve 5-3 uses a proportional valve. Type.

The controller 20 controls the engine 20 such as an engine RPM (Revolution Per Minute), an engine torque, an accelerator position range (APS), a compressed air pressure P (i.e., a filling pressure of the air tank 4) US reproduction processing or the like wet air quantity (Q1) to the input data, the operation mode map 20-1 is the compressed air pressure (P) and charging settings (Cut-off), US reproducing wet air quantity (Q ₁₎ and Set value (capacity), Blow-out mode condition (M ₄ ) (In case of winter (less than 17 ° C at ambient temperature) And an operation mode map 20-1. The air compressor 2, the air tank 4, the first, third, and third solenoid valves 20-1, 20-2, and 20-3 are controlled by the controller 20 and the operation mode map 20-1, OFF, Load, Playback mode, Blow-out (ON / OFF) and OPEN / CLOSE control of the air compressor (2) Mode.

Particularly, the controller 20 and the operation mode map 20-1 may be dedicated controllers. However, by applying the Electronic Air Processing Unit (EAPU), the controller 20 can communicate with the engine ECU (Electronic Control Unit) do.

On the other hand, Fig. 2 shows a method of controlling the operation mode of the pneumatic pressure generating system 1 so as to improve the cartridge regeneration efficiency. Hereinafter, the control subject is the controller 20 associated with the operation mode map 20-1, and the control target is an air compressor 2 for clarification of the system components and the system control elements of the pneumatic pressure generating system 1, And the first, third and the third solenoid valves 5-1, 5-2 and 5-3. The operation mode is a cycle of on-load mode, regeneration mode, off-load mode, and blow-out mode Will be described with reference to Figs. 3 to 6 by way of example. Here, "?" Is an arrow symbol indicating the proceeding order of the operation mode.

S10 is a step in which the compressed air pressure P is detected by the controller 20 and S20 is a step in which the controller 20 compares the compressed air pressure P with the charge setting value Cut-off. The controller 20 detects the pressure of the air tank 4 stored in the clean dry air state as the compressed air pressure P and compresses the compressed air in the air tank 4 using the on- It is determined whether or not an On-Load mode in which air is stored is started.

On-Load Mode Judgment Formula: P> Cut-off

Here, ">" is an inequality indicating the magnitude of the two values.

Therefore, when P is smaller (or less than) Cut-off, the compressed air is required to be filled in the air tank 4, so that the controller 20 switches to S100 to start the On-Load mode.

Referring to the on-load mode of the pneumatic pressure generating system 1 of Fig. 3, the on-load mode is a mode in which the air compressor 2 is operated but the first, second and third solenoid valves 5-1, -3) are not operated, so that the air port of the first and second solenoid valves 5-1 and 5-2 and the inlet / exhaust port of the third solenoid valve 5-3 are turned OFF, The first and second blow ports of the solenoid valves 5-1 and 5-2 are maintained at CLOSE. The compressed air in the air compressor 2 flows from the cooling pipe 6 to the air dryer 3 to the air filling pipe 7-1 to the air tank 4 and at the same time the air filling pipe 7-1 to air All of the air ports of the first and second solenoid valves 5-1 and 5-2 are all turned OFF, and thus are all stored in the air tank 4. "" Is an arrow symbol indicating the flow direction of the compressed air.

Therefore, the high-temperature and high-humidity compressed air generated by the air compressor 2 is converted into clean dry air compressed air from the cartridge of the air dryer 3, and is then stored in the air tank 4, It stops when it meets.

S30 is a step in which the compressed air pressure (P) is a non-playback wet air quantity (Q ₁₎ is detected by the controller 20 in greater than the charge condition setting value (Cut-off) is compared with the set value. To this end, the controller 20 controls the amount of humidified air in the compressed air of the air tank 4, which is stored in the clean dry air state or the clean dry air state, through the air dryer 3 as the unregenerated wet air amount Q ₁ And determines whether or not the reproduction mode is started by using the following reproduction mode determination formula.

Determination of the playback mode: Q ₁ < 500 litter

Here, "" is an inequality indicating the magnitude of the two values.

Therefore, when Q ₁ is greater than (or exceeds) 500 litter, it is required to remove foreign substances (oil, moisture, imulsion) stored in the cartridge (and oil separator) of the air dryer, S100). In this case, the regeneration mode (S100) only removes oil, moisture, emulsion, oil and moisture, which are foreign substances, but does not remove the remulsion.

The regeneration mode of S200 corresponds to the air port ON (MV2 = ON) of the second solenoid valve 5-2 in S200-1, the first air outlet port of the first and second solenoid valves 5-1 and 5-2 of S200-2 (Air compressor OFF) of the air compressor 2 in S203 and the inlet / exhaust port ON (MV3 (ON) of the third solenoid valve 5-3 in S204), two blow ports OPEN = ON), the APU exhaust path formed in the third solenoid valve 5-3 through the exhaust path leading to the air dryer 3, the cooling pipe 6 and the air exhaust pipe 8-2 in step S205 = OPEN).

Referring to the regeneration mode of the pneumatic generating system 1 of Fig. 4, the regeneration mode is such that the air compressor 2 is not operated but the first, second and third solenoid valves 5-1, The air ports of the first and second solenoid valves 5-1 and 5-2 and the inlet / outlet ports of the third solenoid valve 5-3 are turned ON to open the first and second solenoid valves 5- 1,5-2) are switched to OPEN. As a result, the compressed air in the air compressor 2 flows from the outlet of the air dryer 3 to the inlet of the air dryer 3 to the air discharge pipe 8-2 to the inlet / outlet port of the third solenoid valve 5-3 The air branch pipe 7-2, the air supply pipe 8-1, the first and second solenoid valves 5-1 and 5-2, the first and second solenoid valves 5-1 and 5-2, Two blow ports → first and second blow lines 9-1 and 9-2 → a bypass path that flows to the air compressor 2 at the same time. Here, "" is an arrow symbol indicating the flow direction of the compressed air.

Even in the regeneration mode, the high pressure of the compressed air stored in the air tank 4 is supplied to the air dryer 3 even when the air compressor 2 is not operated, Water and oil can be removed from the foreign matter without causing a rise in temperature. However, since the high pressure is not generated due to the operation of the air compressor 2, the elimination effect on the emulsion is very weak. For this, the blow-out mode is separately performed.

S40 is a step that determines the Blow-Out-mode condition (M ₄₎ by the non-reproduction wet air quantity (Q _1), the set value (500litter) and than the controller 20 from a small condition. To achieve this, the controller 20 performs the Blow-out mode (S300) in the regenerating mode three times or more in the winter (less than 17 ° C on standby) or in the regenerating mode five times or more Or not.

As a result, the controller 20 switches to US Off-Load mode of S400 satisfy the Blow-Out-mode condition (M ₄₎ Blow-Out Mode condition when entering the Blow-out mode in S300 and the other hand to meet the (M ₄₎ do.

The Blow-out mode of S300 is a mode in which the inlet / exhaust port ON (MV3 = ON) of the third solenoid valve 5-3 in S300-1, the first and second solenoid valves 5-1 and 5-2 (MV1 / MV2 = OFF) of the third solenoid valve (MV1 / MV2 = OFF) through the exhaust path leading to the air compressor 2, cooling pipe 6 and air discharge pipe 8-2 of S300-3, (Exhaust = OPEN), and operation of the air compressor 2 (air compressor ON) in S304.

Referring to the blow-out mode of the pneumatic pressure generating system 1 of FIG. 5, the blow-out mode is a mode in which the air compressor 2 operates but the first, second and third solenoid valves 5-1, -3) are not operated, so that the air port of the first and second solenoid valves 5-1 and 5-2 and the inlet / exhaust port of the third solenoid valve 5-3 are turned OFF, The first and second blow ports of the solenoid valves 5-1 and 5-2 are maintained at CLOSE. As a result, the compressed air in the air compressor 2 flows into the air filling pipe 7-1, the air branch pipe 7-2, and the air supply pipe 8-1, and the first and second solenoid valves 5-1 and 5-2 while the compressed air of the air compressor 2 flows through the cooling pipe 6 → the air dryer 3 → the air discharge pipe 8-2 → the third solenoid valve 5-3) to form an APU exhaust path which is discharged to the atmosphere. "" Is an arrow symbol indicating the flow direction of the compressed air.

Therefore, in the blow-out mode, the imulsion adhered to the cartridge of the foreign substance can be strongly blown away by passing through the air dryer 3 at a high pressure discharged by the air compressor 2, and the imulsion separated from the cartridge can be compressed Can be released into the atmosphere together.

In the off-load mode of S400, air port ON (MV1 = ON) of the first solenoid valve 5-1 of S400-1, first blow port ON of the first solenoid valve 5-1 of S400-2 (First port = OPEN), and the air compressor 2 is not operated (air compressor OFF) in step S400-3.

Referring to the off-load mode of the pneumatic pressure generating system 1 of FIG. 6, the off-load mode is a mode in which the air compressor 2 is not operated but the first solenoid valve 5-1 is operated, The air port of the first solenoid valve 5-1 and the first blow port are switched to OPEN while the valves 5-1, 5-2 and 5-3 are not operated, while the second solenoid valve 5-2 is switched to the open state, The air port and the second blow port of the third solenoid valve 5-3 are CLOSE, and the inlet / outlet port of the third solenoid valve 5-3 is kept OFF. As a result, the compressed air of the air compressor 2 flows through the air filling pipe 7-1 → the air branch pipe 7-2 and the air dryer 3 → the air supply pipe 8-1 → the first solenoid valve 5 -1) to the first blowing port → the first blowing line → (9-1) → the air compressor (2). Here, "" is an arrow symbol indicating the flow direction of the compressed air.

Therefore, in the Off-Load mode, the compressed air stored in the air tank 4 is discharged to the outside through the air compressor 2, even though the air compressor 2 is not operated.
