Carburetor "Pirburg" 1B1

This single-chamber carburetor with manual choke, or warming up with a semiautomatic device (1V3) installed on many cars of the "Audi - Volkswagen" and "Opel" and "Warburg" during the 80-ies . 1. damper air launcher. 2. lever choke. 3. Adjusting screw rpm engine warm-cold for most elongated handle "leaks." 4. Connector for the supply of gasoline. 5. Connector to return to the tank too much gasoline. 6. Screw plug in the channel idle. Instead, the stub may be mounted solenoid or pneumatic valve antiknock idling. 7. Connector for connecting the vacuum regulator ignition timing. Depression in the tube appears only after the throttle ajar. 8. screw to adjust the quality of the mixture. 9 . economizer Vacuum cardinality regimes. described in detail in the section "Pirburg" 2e2. 10. The vacuum unit cold start "Pulldown". 12. Lever pump the accelerator. 13. adjustment screw rpm. 14. Inertial fist pump the accelerator. 15. Lever Throttle . The initial setup is the throttle just to clean the carburetor. Before adjusting, make sure that the ends of the damper and the adjacent wall of the diffuser do not have traces of soot. Adjustment is a set screw. damper should be as closed, but its edges are not tightly related to the walls of the diffuser. The idling has two independent channels and two fuel nozzles. On one channel, set the adjustment screw of the mixture, and on another channel - the screw-quality blends. Blockage of any jet is unstable momentum cold. turn. A - enrichment valve is located in the body of the screw . in - electromagnetic valve - antiknock system idling. Violation of the thread leads to the valve air intake and volatile turns cold. turn. C - outlet is a mixture of cold. progress. D - throttle. The car "Opel Kadet" instead of a simple screw can be installed vacuum valve to include more enrichment at the opening of the throttle. The valve is connected to the branch pipe, in which depression occurs only after opening the throttle. On the right wing engine compartment mounted pneumatic solenoid valve, vacuum tank and tube with two valves, slowing down. solenoid control relay Forced cold. turn. In idle warmed-up engine valve is closed enrichment. At the time of opening the throttle the vacuum appears in the tube (7) and the valve opens the passage for further enrichment. When engine braking solenoid, located on the right wing interrupts the vacuum valve enrichment is closed. In function enrichment valve body performs a regular (main) part of the adjusting screw rpm. The design of the accelerator pump is made very reliable. His only fault (except for debris) - etopovrezhdenie the piston rubber. P - piston accelerator. K1 - the inlet ball valve pump . K2 - the outlet ball valve pump. D - demfiruyuschy (slow) drive cam. F - injector accelerator. In - the adjustment screw the initial installation of the throttle. Malfunctions valve concentration have little effect on the dynamics of acceleration of the vehicle, in case it breaks you can just drown vacuum tubes on the carburetor and the valve. Injector accelerator can have one hole or two. So be careful when checking in order not to miss one crushed hole. Before adjusting the idle speed make sure that the engine is warm, the choke lever presses did not throttle lever, pre-throttle conducted properly, the ignition is set correctly. Adjusting the cold. the course is held under option A (see "Adjusting the idle speed"). Setting ignition timing on the car "Opel" is a combination of mobile and fixed labels crankshaft pulley on the front with blinking strobe light. Combined labels mean 10 ° before TDC. Motor vehicles "Opel Cadet" with electronic ignition control module, you need to check the status of the vacuum tube that connects the engine load sensor (pressure gauge in the intake manifold) with a socket constant dilution, which is located on the carburetor. pipe damage causes deterioration of the dynamics of Acceleration due to later timing.
