Carburetor "Pirburg" 2e2

Carburetors "Pirburg" series 2E installed on many cars produced in Germany. Certain types of series 2E differ from each other, above all, types of starter. 2E1 carburetor equipped with a triggering device manually operated type 2e2 - fully automatic triggering device type 2E3 - semi-automatic trigger device, and type 2EE made with electronic regulatory elements. These types of carbs are widespread in the European territory of CIS in connection with the wide import of machinery from Europe. Until the mid-90's hit series 2E reliability. Flushing, flushing, adjustment and repair of the unit is completed. Over the years the situation has worsened and is now a rare carburetor complete without replacement of parts. To ensure that the different modes on the carburetor, the following mechanisms: 1. Vacuum Regulator Idle performs 3 functions. Therefore, it is sometimes called the three-position valve controlled throttle. In the first seconds after a cold engine piston rod controller supports the maximum speed of heating (3000 rev / min). After a few seconds the rod is fully retracted, but the throttle lever moves to stop for gasoline heating thermostat. In this case the engine speed drop to 1500-1800 r / min. As the heated coolant thermostat heating gently reduces the throttle and when the engine temperature reaches 60-70 ° C idle is up 700-800 rev / min. Scheme the carburetor vacuum connections "Pirburg" The letter X denotes 2e2 tube heating system air, which can be used to adjust the idle speed for option B. Warm-up time with a working engine cooling system is from 4 to 7 minutes, depending on the ambient temperature. During the warm-up when the engine speed 1000-1200 r / min shaft-load regulator abruptly goes to the middle position, corresponding to the idling speed and waiting for the moment when the carburetor heating thermostat fully release the throttle. On the hot engine idle speed vacuum regulator controls only the idle. To increase or decrease the speed on the controller has a cap screw 13. After turning off the ignition control rod is completely hidden, throttle closed, and creates a condition for stopping the motor without the effect of the detonation. In addition to the stop mode motor control rod is hidden for a short time after peregazovki, creating a regime (PHH) overrun during engine braking. (1 - stem is fully extended when the engine is running, 2 - stem in the middle position in the mode of cold. Stroke, 3 - rod completely hidden in the mode of PHH or when the engine stops). 2. Vacuum cardinality economizer mode. Opens an additional channel of gasoline in the main metering system, the first chamber during heavy throttle. 3. Warm the thermostat that controls the throttle lever. His goal is to keep the engine is cold increased speed until the coolant warm. At a temperature of engine 60 - 70 ° C thermostat must release the throttle control to stop idling. 4. Adjustment screw quality of the mixture. 2e2 carburetor - one of the few in which the adjustment is effected by changing the quality of the mixture of air in the system idling. Untwisting the screw impoverish the working mixture, twist - rich. Under the adjustment screw is a main jet idling. 5. Adjustment screw rpm. 6. Balancing channel float chamber. Click to create a small vacuum in the float chamber at medium and high engine speeds. 7. Start-up air damper. The engine is cold is completely closes the outlet air. 8. Vacuum unit cold start "Pulldown". After a few seconds after a cold start this device opens the launcher choke on the value of the first start of the gap. After another few seconds, the device increases the start-up valve clearance on the value of the second stage. Value of the first gap of 1.5-2 mm. Value of the second gap 3 - 4.5 mm. 9. Air jet in the transitional system of the second camera. 10. Connecting the vacuum hose between the carburetor and cold-start device. 11. Plug and socket electrical heating system idle channels. 12. Socket connection to a vacuum system, heating the air, which is in the air filter housing. Fitting is also used during idle speed adjustment for option B. 14. The accelerator pump. 15. Adjusting screw to maximum speed of heating (no more than 3200 rev / min). 20. The control unit air starting valve. Inside the device is a bimetal coil spring, which outer end is connected to a movable arm choke, and the inner end with a fixed holder spring. The device operates on the principle of a bimetallic spring unwinding of heating the cooling fluid. The engine is cold spring is compressed and closes the choke. As the warm spring unwinds smoothly and opens the choke. Under the spiral spring is a wire heater. Its purpose is to heat the helical spring up until the coolant temperature rises to 55 ° C. After that, the heater is turned off and the spring in the future receives heat from the coolant. 22. Ekonostata spray. 23. Termovremennoy pneumatic valve. In the cold air passage open. After the power supply 12 volts from the ignition switch inside the valve starts to heat up the bimetallic plate. The normal warm-valve ranges from 4 to 10 seconds. After warming the air valve passage is closed. 24. Epv. Controls the vacuum regulator of idling. Meals "Plus" 12 volts supplied to it after the ignition. "Less" gives a small electronic unit (TFK), which is located near the fuse panel. In elektroinevmoklapana has two states: ON - air passage open and OFF - air passage is closed. When the engine valve control unit TFK. Is controlled by the "minus". When turned on the vacuum regulator valve switches to ventilation (control rod is in the middle position). When the valve stem off the controller completely hidden. These checks should be carried out on engine running. 30. Supply hose to a pneumatic actuator vacuum opening of the second chamber. 31. Pneumatic opening of the second chamber.
