Alternative method to repair the economizer is used in the case where there is no way to get a repair kit carburetor. In this case, you can temporarily mute the fuel economizer channel, resulting in minor loss of the dynamics of a sharp acceleration the car, but at the same time, significantly improved all the main characteristics (fuel economy, idle stability, etc.). To this end, the hole on the side of the body economizer, where the valve is pressed tightly to a lead pellet of the appropriate size. On the other side of the case, where there was a diaphragm, you need to install the gasket in the form of petrol-resistant rubber diaphragm, which should be only two holes for the screws. After that, collect the whole design without economizer springs and set into place, using the native rubber gasket, which rarely fails. This method stub economizer can be used on any carburetor family "Pirburg" because the design of economizers is the same. Wiring diagram vacuum regulator idle: Z - throttle zasloka; H - stock controller idle, 1 - idle control, 7 - choke 23 - termovremennoy valve, 24 - epv. The first phase of a cold start: Idling the engine warmed up: The mode of forced cold. speed or stopping the engine: a breach of the thermostat is warming up for a long time warming up (increased speed) with good cooling system thermostat (normal engine warm-up time - from 3 to 6 minutes depending on ambient temperature), the lack of a smooth decrease in speed as the warm-up motor constant overestimate the idle speed. A sign of a faulty thermostat heating may be a gap between the rod control of idling and the throttle lever on the motor is running hot, as well as detonation (dizelirovanie) warmed-up engine at the time of ignition is turned off. The first thing to check cable tension of gas, and then move on to checking the thermostat. The reason for the unsatisfactory work of heating thermostat can be no circulation of cooling. fluid through the channels and the intake manifold carburetor pipes mechanisms. Most often the blockage at the site of the channel joint intake manifold with the cylinder head. Check the quality of the circulation can be touching her hand to the control unit air damper, which is on the hot engine must have the same temperature as the engine temperature. If the temperature of the device is significantly different (colder) from the temperature of the engine, so there is a blockage of channels or understated the level of coolant in the engine cooling system. When the symptoms are observed in the normal circulation, it means that the thermostat is warming the carburetor is out of order and should be replaced because it is not subject to repair. As a temporary measure, is practiced by disconnecting the cam lever to raise the thermostat turns, leading to complete elimination of the influence of the thermostat to throttle position. To remove the cam is required to unscrew the screw fixing it (hexagon 5 mm), crank cam clockwise until it stops and hold it in such a position wire loop. After this operation, normal operation warmed-up engine at idle and it is possible to adjust the carburetor complete. The only disadvantage of disconnecting the thermostat is working in the mode of heating cold engine will have a few minutes when the engine speed to maintain the gas pedal. To warm the engine all the rest of the system will operate normally. The reasons for the disappearance of the idle speed. Clogged fuel jets idling. Nozzle body is under the adjusting screw. To get a jet, you need to unscrew a screw shell and remove it. For loosening the nozzle should be used with a screwdriver blade width of 5 mm. To extract the jet should be used ostrozatochennuyu match. In the adjusting screw housing quality is going to a lot of soot, so before installing it is recommended to thoroughly wash the air gap, screw and lubricate the threads with engine oil and a sealing rubber ring. Lack of power supply 12 volt solenoid. In this vacuum regulator shaft idle completely hidden and throttle is closed. If there is such a failure should find out what was lost - "plus" or "minus" supply. Dropouts, "plus" means a burned fuse. Dropouts "negative" - ??failure of the electronic control unit of TAC, which is located on the relay and fuse. Alternative repair. To recover the electric control system idling in the following way. "Plus" to file a valve on the supply "15" Ignition Coil, and "minus" - from the "masses" of the engine. This connection will stop working mode at PHH engine braking, but the idling and stop the engine will operate normally. So you can repair use when you can not replace a faulty electronic control unit or having difficulty in finding "plus". a great influence on the stability of idling has an intake manifold leak. The most common causes, because of which are leaking hull damage rubber cushion mounting the carburetor, the break of the rubber pipe that connects the intake manifold vacuum assisted brakes, bummer small plastic tubes, which connect the vacuum mechanism. carburetor "Pirburg" 2e2 has a greater tendency to freeze in the damp cold weather. why should the chapel proper attention to heating air entering the carburetor. Adjustment idle without gas analysis is carried out perfectly for option B (see "Adjusting the idle speed"). Before starting the engine cold air damper is closed. rod controller Hall. of the fully extended and holding the throttle slightly open in the original position termovremennoy valve is open. When the ignition voltage of 12 volts is applied to termovremennoy valve, the heater wire spiral bimetallic spring, electric channels of idling and the heater intake manifold. After starting the engine air damper opens to the starting value of the gap, termovremennoy valve closes after a few seconds after the at him and voltage regulator rod retracts fully. Throttle speed is kept at high heating thermostat cam. electropneumatic closed, as at higher engine speeds electronic control unit disables the TRC "minus" of its power. In the process of heating the coolant thermostat heating reduces engine speed, and when the value of 1200 rev / min. epv included, creating the ventilation control of idling. In the ventilation shaft controller occupies a middle position and looks forward to touch the throttle lever after a full warm-up. On a hot engine air damper is in an upright position, the throttle lever kept at idle vacuum regulator shaft, electropneumatic open termovremennoy valve is closed and is always energized when the ignition key. When the coolant temperature reaches 55 - 65 ° C, temperature switch, located on the nozzle of the cooling system will power the heater spiral bimetallic spring from the heater and the intake manifold. At the moment of ignition is turned off electropneumatic regulator closes the ventilation of idling, the piston rod is hidden, using the residual power vacuum in the intake manifold and the throttle closes. After stopping the engine control rod fully extends and set the throttle to its original position.
