Removal and installation of the distributor of ignition Components of the distributor of ignition
The general information Design features of the distributor and principle of functioning of regulators of ignition The ignition gauge-distributor provides necessary sequence of giving of impulses on spark plugs; develops the impulses of pressure sent then in ECU and operating interruption of a current in a primary winding of the coil of ignition. The basic making components of the distributor are: the generator of electric impulses, the scheme of division of pressure in a secondary chain; a centrifugal regulator and vacuum-proof-reader of an advancing of ignition. The distributor drive is carried out from the gear wheel put on an axis which are in gearing with a gear wheel of a cranked shaft. Frequency of rotation of an axis приводной gear wheels twice below frequency of rotation of a cranked shaft. The case of the distributor of ignition from above is closed by a cover which fastening is carried out by means of two spring clamps. The case flange is intended for fixing of position of the distributor. The cover is executed from нетокопроводного a material maintaining high electric loadings, equipped by five plugs concluded in nests of ledges of a cover. Wires ВВ of a contour of system of ignition are connected to plugs. To the central plug of a cover of the distributor it is connected ВВ a wire from the ignition coil. The plug by means of подпружиненного coal contact is connected with бегунком the distributor. The remained four candle plugs directly are connected with запрессованными from the interior of a cover brass contacts. Near to one of plugs outside on distributor covers it is put long vertical convex risk. To the given plug it is connected ВВ a wire of a candle of the first cylinder. The distributor shaft is fixed in the case of the distributor by means of two self-greased plugs. In the bottom part of a shaft the shaft is provided, and on the top the plug into which it is inserted бегунок is established. In the top end face of the given plug there is a groove guaranteeing unambiguity of installation бегунка. Бегунок it is made of a dielectric material. From above in it запрессованы two brass plates between which the resistor intended for suppression of radio-frequency hindrances is located. The plate established in the central part бегунка, by means of a coal brush is connected to the central plug of a cover of the distributor. Thanks to such design, ВВ pressure from the ignition coil through помехоподавляющий the resistor appears brought to the second brass plate fixed on a nouse бегунка and at work of the engine of cover serially contacting with candle plugs of the distributor. The magnitoinduktsionnyj gauge (the Hall gauge) consist from 4-polsnogo a rotor, a ring with polar cores and the induction coil. At rotor rotation power lines of a magnetic field periodically interrupt. Magnetic field change leads to production of impulses in a winding of the induction coil. Further these impulses arrive in ECU, operating passage ВВ of pressure through the ignition coil. |
