The system start the engine - the general information and precautions
general information The only task of the engine starting system is to provide the motor rotation at a speed sufficient to start it. Starting system consists of a starter, battery, ignition switch, magnetic switch and connecting wiring. The starter motor is a direct current with the mixed excitation and installed outside the electromagnetic traction relay. The starter consists of a body or stator windings excitation armature Freewheel, covers with brush holder and the traction relay. When the starter through the winding of the traction relay current begins to flow from the battery. Anchor the relay contacts are closed and retracted. Simultaneously the relay anchor through the drive gear lever provides extension with overrunning clutch, with the coupling hub rotates screw slots armature shaft and the starter turns as well a gear wheel that facilitates the insertion of the latter into engagement with the flywheel. Through the closed contacts of the traction relay is a current feeding the stator windings and the armature and the starter anchor starts to rotate together with a nave and overrunning clutch. After starting the engine speed exceeds the speed gear anchor of a starter. In this case, one way clutch rotates freely and no torque is transmitted from the flywheel to the shaft of the armature of a starter. After releasing the ignition feed circuit winding traction relay through the ignition switch is opened, the anchor of the traction relay is wrung out by a spring in its original position, the relay opens and the drive gear is disengaged from the flywheel. The starter with magnetic switch is parallel to the crankshaft of the engine and secured to the power unit. Safety measures When carrying out any work on the system, start the engine, observe the following: - To avoid the e / motor failure due to overheating, do not operate the starter more than 15 seconds - before turning it on again, wait at least 1 minute. Long cranking the starter motor does not start leads to accumulation of unburned fuel in the catalytic converter, which is fraught with the last failure as a result of the implementation of the ignition run;
- The starter is connected directly to the battery and careless handling can cause fire due to short circuit;
- Before starting maintenance work, always disconnect the starter battery negative lead.
