Carburetors K-151

Carburetors K series - 151 represent the latest generation of carburettors, produced by JSC "Pekar" (St. Petersburg carbs). K - 151 are installed on the car "Gazel", "Volga", UAZ. The difference engines, which are set to - 151 is taken into account in the amount of dosing elements reflected in the alphabetical index assigned to each type of carbs. 1. Screw rpm. 2. Block of cold. stroke. 3. Screw the quality of the mixture. 4. Aperture pneumatic valve system of forced cold. stroke (PHH). Damage to the diaphragm is the cause unstable speed cold. stroke. 5. The tube is connected to a constant vacuum. The initial position of the throttle both chambers to be closed. At idle, fuel mixture is fed into the engine block of the system only through the cold. travel (2). 6. The vacuum unit is connected to the system idle from the lower pipe with a constant negative pressure. 7. In the upper nozzle vacuum appears only after a small throttle openings, it connects to the vacuum regulator ignition. A common reason for the lack of idling is a bad connection of vacuum hoses. Under some fault in the mechanism of the centrifugal distributor connecting the vacuum tube from the carburetor to the distributor can cause a drop in engine power, acceleration and failures, etc. Therefore, it is recommended to check first ride quality without having to connect the vacuum regulator ignition, and then - with the connection. 8. Clogged pipe ventilation of crankcase gases in the cold. course leads to the enrichment of the mixture. 9. Metal gaskets, leaking gasoline, it is necessary abraded on a flat stone. 10. One of the frequent failures to - 151 is jamming the mechanism of manual control of air and the throttle during a cold start the engine. Therefore, we recommend that before pulling the lever damper pre-press the gas pedal. 11. The deformation of the pressure surface of the upper lid occurs when inhaling carburetor air filter housing without restrictive sleeves in three of his heels. Deformation leads to leakage of gasoline from the float chamber. 12. The device and the accelerator pump failure are similar for all carbs. OF - 151 easier access to the inlet ball valve accelerator, which is under the restrictive screw with rubber seal. The system is overrun to block the fuel supply system idle during engine braking (coasting downhill on an included gear and released the gas pedal). When you disconnect the fuel saving fuel, wasted-burning engine, and significantly reduces emissions of unburned hydrocarbons CH. Turn off the gasoline produces a pneumatic valve (10), which is controlled by a solenoid valve (6) by a team of electronic unit (7). 1. Emulsion well the main metering system. 2. Emulsion tube of cold. stroke. 3. Emulsion jet. 4. Air jet. 5. The main jet of the primary chamber. 6. Solenoid valve. 7. The electronic control unit PHH. 8. Microswitch. 9. Membrane. 10. PHH valve. 11. Screw quality. 12. Knot Hole. stroke. 13. Screw quantity. 14. Diffuser. 15. The transitional gap. 16. Throttle valve first chamber. PHH system failure creates various problems with idling. To eliminate the influence of PHH carb work to directly connect the valve to PHH constant dilution. Adjusting the carburetor without the gas analyzer is under option A (see here - "Adjusting the idle speed").
