System of start of the motor - the general information and precautionary measures General information The only task of system of start of the motor is supply of Drehens of the motor with a speed, there is enough for start.The system of start exists from a starter, the battery, the switch of ignition, the relay and the line. The coming relay is on a starter body. The starter represents the electric motor of a direct current with the mixed incentive about electromagnetic tjagowym of the relay. The starter exists from a body or statora with parcels of an incentive, an anchor with obgonnoj muftoj, covers with schtschetkoderschateljami and tjagowogo of the relay. At the appendix of a starter parcels of tjagowogo of the relay of a starter battery current begins to pass. The anchor of the relay participates also in contacts are closed. At the same time the relay anchor the obgonnuju muftu lever translates with a gear wheel. The obgonnoj mufty plug turns on screw schlizach of a wave of an anchor of a starter and turns also a gear wheel that its introduction facilitates in intervention with a gear wreath of a flywheel. The closed contacts of tjagowogo goes the relay current which feeds parcels of statora both an anchor, and the anchor of a starter begins to remove begins together with the plug and obgonnoj muftoj. After start of the motor the frequency of Drehens of a gear wheel passes the frequency of Drehens of an anchor of a starter. In this case obgonnaja mufta proworatschiwajetsja is free, and the torque will not transfer from a motor flywheel to a starter anchor wave. After ignition key otpuskanija a power-supply circuit of parcels of tjagowogo of the relay the ignition switch, the anchor of tjagowogo of the relay of a feather of otschimajetsja will be in a starting position left, contacts of the relay also a gear wheel of an incentive it from intervention with a gear wreath of a flywheel is left. The starter with the coming relay is located parallel to a bent shaft of the motor and strengthened on transmission gears. The relay of a chain of system of start is located in the central processing unit according to number 17. The starter is enlisted, only if there is Selektor AT in situation "R" or "N". If the car is not in the protection mode, prowernetsja starter. Precautionary measures When carrying out any works with system of start of the motor you pay attention to the following requirements:a) do not consider a starter long time is made. It can and are cancelled overheat. Do not accept a starter more than on 15 seconds, and before the repeated appendix you expect along with 2 minutes. If you are not started by proworatschiwajete start long time, and the motor, not burning down fuel within the reformer gathers. It can lead to an overheat of a working surface of the reformer after start of the motor; b) if the starter directly joins batareje and in the chaotic address can or cause short circuit ignite; c) Prior to works always you exclude a cable of mass of the battery. |
