Description

[Detailed description of the invention] The present invention enables engine exhaust gas to circulate and at the same time adjusts fuel injection timing. This invention relates to a system for controlling emissions from diesel engines.

Unburned hydrocarbons (IC), -carbon oxides (CO) and nitrogen in diesel engines Simultaneous control of oxides (NOx) requires precise control of exhaust gas recirculation (EGR) and injection timing. need your help. NOx control is the use of EGR, which is designed to reduce the oxygen concentration in the combustion chamber by 7. Obtained by use. However, the amount that can be used depends on engine displacement and combustion. t'L is limited by the percentage of air in the charge obtained. Excess air A critical amount of smokeless combustion, maintained for the dawn (still maintained by use during the period) can be achieved. At light loads where the amount of EGR used does not limit engine displacement. In some cases, injection timing may be advanced to improve hydrocarbon control.

Therefore, the present invention provides optimal control of hydrocarbon, carbon oxide and nitrogen oxide emissions. We provide diesel engine control that automatically predetermines EGR and injection timing. Related to the system.

Another advantage of the present invention is to minimize the output of emissions from a T-filled fuel tank. The change in EAR flow combined with the retardation causes the injection timing to advance. speed and load conditions as well as the fuel injection pump. Three-dimensional cam that responds to changes in delivery volume It is to share control/system. Injection time? The only thing that can be advanced is inside the combustion chamber. It provides better consumption of fuel and longer residence time. delay injection time What is possible is to lower the peak fuel Rv = T5i, thereby reducing the amount of N○ production. Ru.

It is divided into an atmospheric chamber 48 and a vacuum chamber 50 by an OT-connected diaphragm 46. The ring 45 is also of a known type.

The chamber 50 causes the diaphragm 46 and the EAR valve 42 to move toward the closed position. 52 beggars are locked up.

The real currency supply source that regulates the flow of this platform ECR is the vacuum port shown schematically at 54 points. Provided by Nde.

The bonder includes a vacuum redever 56, a low temperature reaction valve 58, and a speed sensitive vacuum regulator 6. 0, and connected to the EGR servo 44 via the EOR vacuum regulator unit 62. There is. The Shinkyo ritual instrument 60 has a load crank @ 66 to respond to changes in speed. It is magnetically connected 7 to a tachometer 64 driven from the tachometer 64 . The regulator 60 is The output vacuum varies from a minimum to a maximum as a function of the change in speed. The engine is configured to provide an output proportional to the engine speed change. It is supplied to the vacuum pipe 68.

The output 0 node in i 68 is FORl: 1 of the air conditioning u6 unit 62. It is connected to stand #70 where input is required. The unit is annular, The housing is divided into a vacuum chamber γ8 and an atmospheric pressure chamber 80 by a diaphragm 76. cut from the g. Atmospheric pressure chamber 80 communicates with the atmosphere through a vent 82 . essentially The U-shaped housing or subassembly 84 or diaphragm 76 and It is mounted to move together with the moving rod 86. The spring 88 is as shown (as described above). The method for applying 4 pressures on the circular valve 90 to the annular bent edge 92 of the subassembly is as follows: , when the diaphragm 76 is moved to the right as shown in the drawing, the square It is seated against the open end of the stand 'α70, and the vacuum flows from the stand to the chamber γ8 +]E.

Have them sit against each other. The subsequent movement of diaphragm 76 to the right causes The edge 92 of the subassembly is separated from the circular root valve 90 to allow atmospheric air to flow from the interior chamber 96 into the vacuum chamber 78. The vacuum level of the vacuum chamber is reduced until a horizontal position of the subassembly is obtained by allowing the flow to flow to the make you feel the same

Position of lever 100 (FIG. 4) pivoted at spring 102 of tension spring 98 Depends on that, lol. It depends on engine speed and load and fuel, IF5 - injection pump is moved in an arc in response to changes in pump delivery. Reba asked me to explain in more detail. - 100 or one end thereof, the tension spring 98 is adjustable and pivotably connected to the tension spring 98; 'are doing. Near its midpoint, it supports roller 104, which roller operatively engaged with contour surface 106 of dimensional cam 108 It matches.

The cam 108 is shown in detail in Figures 6 and 4. The old capital would later be divided into five generations. In summary, the rotating thin wire 110 of the cam 108 is rotated with the vehicle accelerator pedal by a lever 112, shown schematically at 114. It is installed to rotate. When the petal is pressed down and/or released, the cam A corresponding rotation of shaft 110 results. The cam 108 is also controlled by the military 9 The axis 110 of the bo 116 moves i=9 and the slide (b) moves freely. The roller 104 moves in the axial direction along the circumferential surface of the cam 108. let Servo 116 is coupled to speed sensitive vacuum regulator 60 by true control path 117. It is. As shown by the dashed lines in the drawings, the F-thin 110 further includes: Shipping fee! -7 to control the EAR flow in proportion to the fuel injection pump fuel city 1'' control. When rotated simultaneously with lever 118), it is identified and connected to J:5. The material is sent out by a machine. Therefore, the direction of rotation of the cam 108 depends on the load.

The contour of the cam 108 is determined by, for example, ECR regulator spring stroke versus vacuum force, EGlj valve position. and E(E4(rate relationship) shown in FIGS. 2A and 2B, n It can be ground to occur in the regular PJ + desired FOR schedule.

This is the fitting regulator output pipe 68 to the control valve 122 and connected to the three-way solenoid by the control valve 122. The idling speed EOR is controlled by the vacuum regulator 120n. I will write about it later In particular, when the first valve is under the condition of idling speed movement, the three-way solenoid control valve 122 is sent to the EGR servo 44 through the predetermined summer air/mold idle running FOR vacuum regulator. It is operated as follows. This is the preliminary determination of the vacuum signal in the tube 68 by the vacuum regulator 120. Reduce the emission to a certain level and bypass the EGR regulator 62 unit 62. By doing so, it is achieved.

The fuel cylinder f fuel injection timing control device 6 is located opposite to the crankshaft vertical axis 126 on one side. The first phase shift vehicle 123 measures the rotation of the fuel cylinder input shaft 124 in the other direction. Bodhisattva.

Annular flexible diaphragms 146, 148, 150, respectively within the housing of the servo. 152. Each servo is constructed in the same manner as the EAR servo 44. The I+Il] part of the structure will therefore not be described repeatedly. is One is a smaller surza rod that moves the control rod downward as shown. 162.164 for the force of the illustrated return spring which provides a predetermined stroke of ．． 166.168 indicates that the diaphragm against the stopper? Power to the lower blade There are 1 individual vacuum input tubes 154, 156, 158, 160 pieces. In other words, it would be a minute of light. Spring 170 moves rod 136 to the first high speed heavy load position shown. (biased upward until the point). Rod 136 and four servos are connected in a stepped manner. , and thus the sequential actuation of the servo is essentially equal increments downwards to the conduit 1. Pivot 36 pieces progressively. In this case, the sequential operation is from the first delayed settling to the injection 4 Proceed sequentially to provide the desired operation that is consistent with changes in the EC)R flow. Sea urchin begs for a schedule.

The flow of vacuum to each individual servo is controlled by a plurality of vacuum flow control valves 17. Controlled by 2.114.176.178. These valves are commonly supplied by 18 8 through the blue 180.182.184.186 key from the resapper 56 Empty supplied. The summer air regulator 60 also has two vacuum-opened electric switches 190, 192 will be provided with summer supplies. These switches are connected to the solenoids of valves 112-178. The shoes are constantly closed to complete the electrical circuit. At high speed , the high vacuum opens switches 190 and 192 to cut off the circuit and as described below. At the first moment of the goal, disable each servo.

Valve 172 operated by a solenoid is in this case switched by 1194. The switch 190 is electrically mated directly to the switch 190, and the hot point of the switch 190 is It is closed off in a cruel and oppressive way. Control operated by solenoid Control valve 176 connects the solenoid through normally closed switch 192 and line 198.

The micro switch The other contact 206 is coupled to a portion of the fuel injection bonzo fuel control lever 118. There is. The microswitch contact is connected to the fuel injection cylinder when the control lever is under heavy load. It is always closed when it is in a position other than the opening. Therefore, sui, nochi When 204 is closed, the vacuum side legs 190 and 192 are closed. As long as it remains the same, the valve 1 in addition to the solenoid of valve 172 Supplied to solenoids 76 and 178.

A second idling speed microswitch 208 is coupled to the fuel alpha injection bonding control lever. and is closed when the lever is activated to its idle fuel flow setting. child This energizes the line 210 connected to the solenoid of the valve 174 to open the vent valve and Vacuum is supplied to the rotation speed control servo 138. At the same time, low speed and low load Therefore, servo solenoids 140, 142, 144 are energized. 1 ~ Kashi, Reba - Due to the air movement connection with 136, the rotation speed can be increased only in the stroke of Yarbo 138, or Do 136 good luck.

The idling micro switch 208 is connected to the three carnoid operated valves 122x and 212. Therefore, gakatsukisa71. The valve and the idle speed vacuum regulator 120 are energized at the same time. At the same time, set the 7 EGR servos to position the EGR valve 42 at the idling speed position. , 1 yen cut, 1 m transmission, 1 length vacuum level power. This time, figure 20 8 will cause the injection timing to advance or lag as planned. The graph shows the sequential movement of one solid servo 138.140.142.144. It is shown in

As already mentioned, FIGS. 6 and 4 show the six-dimensional cam 108 and its axis. Its servo mechanism 116 for translational movement along with the groove is shown in detail. Ru. More specifically, the unit rotatably receives the shaft 216 through one shaft and has one outer shaft. Includes Uzing 214.

A lever 112 is fixed to the outer end of the shaft, and the lever is connected to the vehicle accelerator pedal and fuel. In order to cause all of these six members to rotate simultaneously with the injection bonder I/par 118, It is set to be y-coupled. Three axially guided along @216 A five-dimensional cam 108 having a shaft 220 extension is mounted within the housing 214. It is fixed at 216. The cam projects through the slot 224 of @216 It is connected to @216 by the bottle 222 that rotates and can be freely rotated many times. There is. It also protrudes through and is integral with the second base sleeve 226. It is installed to move in 1I8.

228+'i The remaining part of the inside of the housing 214 and the prisoner's room 23 It is connected to a ring-shaped diaphragm 231 consisting of two elements. The truth De is combined with Shinken Mining Unit 6U to JIE with a population of 117 and a population of 234. It's shining brightly. Spring 23b can be seen in FIG. 5, it is constantly compressed downward by the fJJ fixing device shown in the figure.

Translation or axial movement of cam 108 by servo 116 (i, radius of roller 1υ4 The force of the draw/flame spring 98 is applied to the Shindo coin dispensing unit 62 by causing a directional movement. Change it (Thus, change the flow of vacuum to FOR Zase 44, 3 also V + - 7 years old Shifc, J2 + ECdR proficiency t to within the 1st size is d month easy, ra. Dew. In addition, any rotation of the cam 108 to any + position or change of position will prevent the contour of the cam radial movement of the rollers 104 inwardly or outwardly depending on the - By changing the vacuum force of Bo 44, it is possible to change the EC-f. It should be obvious.

The square 58 is used to adjust 60 during low-temperature fluid operation. 4-chip on/off temperature-responsive valve used in Below a predetermined temperature , valve 58 is closed, so the vacuum is applied to EGR servo 44 and injection timing servo 1. 38.140.142, T2 does not flow as 144.\. Fit means FOR. Therefore, the injection timing will be delayed by 7Lζ relative to the cold start and operating conditions.

It is believed that the operation of this system is clear from the above explanation and consideration of the drawings, Accordingly, the details will not be described again. It is warmed by 9 minutes of light, and when 58θ1 is opened, it becomes 1 reaction. If the vehicle If the θ sword DI pop pedal or its grass is 16 years old, it will be 1 year old. Mu108 and I'J! N Sento Pump City 11 1 Shi・Ma 118 is the idling speed setting point t'11, thereby causing the rotational speed of the micro-injection 204 to move. I will make it. As a result, the idling speed solenoid tfill rIMl 'f　174-\ time, the bribe was completed, and the summer sky 4f was opened and idle speed The output is supplied to the servo 138 (l''L2).Then it is 136 to the multifilter Rono.
