The ignition distributor
Specifications

The gap between the xcontacts of the breaker, mm .......................... 0.45 0.05 UZSK ................................................. ........... 50 ± 2 ° 30 ' xcontacts, the xcontact pressure, kg .................................. 0,5-0,63 The capacitor, uF ....................................... 0,18-0,26 The electrical resistance of the combined coals temperature (20 ± 5) ° C, ohm .................................... 8000-13 000 The direction of rotation of the shaft of the distributor from the chopper cam .................................. Left Rotational speed of the roller, which provides a uninterrupted sparking on the standard three-electrode spark arrestors needle a gap of 7 mm, 1 \ min ........................................ 3000 Distributor of the R-147a, R-147V breaker consists of a low tension, a centrifugal regulator, the vacuum regulator valve current high voltage. Distributor roller is driven by the crankshaft through the drive shaft of the engine valve. Low-voltage breaker consists of a plate 18 (Fig. 208) chopper on which the pin rack 2 (fixed xcontact) and a movable 22 Pin, tetrahedral cam 5. The surface of the cam is lubricated Fils 6 plate fixed to the chopper. The gap between the breaker xcontacts adjusted by moving the rack in the lowered xcontact screws 1 and 4. Parallel to the xcontact breaker is on the capacitor capacitance 7 mF 0,18-0,26, mounted on the distributor housing. Distributor roller rotates in plain 8. Bearing Lubrication through the hole nine nipples. Distributor of high voltage current is made up of the slider (rotor) 13 xcontact plate 14 and cover 15 with the electrodes that are connected by wires with the coil and spark plugs. In the central electrode of the distributor cap Combined mounted ember 16, consisting of a pin, and coals resistance, used to suppress interference with the radio. xcontact, Combined coal under the action of the spring 17 is pressed against the xcontact plate thumb. Distributor Rotor, rotating, high voltage passes through central electrode cap to the side and below the electrodes to the electrodes in the spark Order of the engine cylinders. Centrifugal control ignition timing is working under the influence of centrifugal force that is created by the rotation of the distributor shaft. Under the influence centrifugal weights 10 apart and turn the cam 5. The springs 19 hold the weights in the initial position. With increasing frequency rotation of the engine crankshaft weights rotate in the direction of the cam 5 rotation, the result is the earliest opening of the xcontacts breaker, ie, increase in ignition timing. When the frequency decreases rotation of the crankshaft under the action of the springs move the weights in the cam the opposite direction, the ignition angle is reduced. The mass of weights and tensile force springs are selected so as to ensure the change timing depending on the speed of the crankshaft in the engine relations below. -------------------------------------------------- ------------------------------ Shaft speed, 1 \ min 500 700 1800 2800 -------------------------------------------------- ------------------------------ Advance angle, ° 0-2 4-6 S-11 13,5-15,5 -------------------------------------------------- ------------------------------ The vacuum regulator ignition ignition timing changes in the Depending on engine load. With increasing or decreasing the load changing the pressure in the engine intake system and engine, respectively, in body cavity vacuum regulator. The cavity of the mixing chamber carburettor connects a pipe. Ball bearing 11 pressed into the plate circuit breaker is used to reduce friction between the plate and the circuit breaker mounting plate 18, which allows for more precise ignition timing vacuum regulator. Characteristics of vacuum regulator ignition -------------------------------------------------- ----------------------------- The negative pressure, mm Hg. of Art. 80-120 120 150 200 -------------------------------------------------- ----------------------------- Advance angle, ° Getting Started 0-3 5.2 5,5-7,5 -------------------------------------------------- ----------------------------- UZSK adjustment and gap between the xcontacts as follows. Loosen the screws 1 and 4, attaching the stand to the xcontact breaker plate 18. Insert a screwdriver into the slot 21 on the front xcontact and increase or decrease UZSK Stand on a scale approaching or removing a xcontact from the xcontact lever bar breaker. Tighten the screws holding the stand to the xcontact breaker plate. For adjusting the gap between the xcontacts of the distributor shaft rotate until until xtextolite block breaker lever does not become the ledge cam faces, while the gap between the xcontacts will be greatest. The gap between the xcontacts, check the probe, if necessary, adjust it. Adjusting the gap between the xcontacts made as well as the adjustment of UZSK. Москвич-412
