Ignition system maintenance and repair

1, regular cleaning and inspection of the external ignition system to ensure that the ignition coil shell is free of grease, dust, damage, no loose terminal, etc., and timely replacement of aging or damaged ignition coil, and at the same time, to check the performance of its work.

2, to prevent the ignition coil heat, moisture, maintain its good insulation properties, for the ignition system to create a good working environment. If there is water on the ignition coil, wipe it with a cloth in time.

3, do not turn on the ignition switch when the engine is not running, to avoid increasing unnecessary consumption. Even if the ignition system does not have any faults, it is generally recommended that the vehicle every 20,000 kilometers or so can be checked, after 60,000 kilometers should be replaced with a high-pressure ignition line, such as if the engine appears to be running erratically, can not start the phenomenon before checking, it is very likely that a lot of fuel has been wasted, and the engine has caused irreversible wear and tear.

4, if the owner likes to frequently check, clean, update the corresponding parts, then the spark plugs, ignition coils, wiring connectors, etc., the chance of failure is higher, need to pay extra attention. In addition, the ignition system in the distributor cap, distributor head, spark plug plugs and other components should also be routinely maintained, check to ensure that the car can operate normally.

The ignition system of the car directly affects the engine performance, and determines whether the engine can work properly. But it is also the gasoline engine systems in the most prone to failure of the system, so car owners in the car to do a good job of daily maintenance at the same time, but also try to let people easy to ignore the ignition system to pay attention to.

Engine as the power source of the vehicle, known as the image of the vehicle's "heart". The performance of the engine has an important impact on the vehicle's driving performance. Therefore, in the daily life of the vehicle, the engine maintenance is crucial to the maintenance of the vehicle. The next focus on the engine ignition system requires regular maintenance of the project.

1, spark plug

With the spark plug service life 'increase, spark plug electrode will be due to ablation and increase the discharge gap, making it difficult to produce sparks. At the same time, the insulating end and the electrode on the carbon will also hinder the spark jump, reduce the current, thus reducing the ignition efficiency. Therefore, spark plugs should be cleaned or replaced regularly.

2. Disconnecting contacts of the distributor

With the increase of the use time, the disconnecting contacts of the distributor will be burned out, resulting in poor contact. The contacts should be checked and replaced regularly.

3. Ignition timing and shut-off angle

Ignition advance and delay angles have a great impact on engine performance. The contact angle is too small, the ignition coil primary current is small, the spark plug spark is weak, the contact angle is too large, the contact point premature wear. Ignition timing and closing angle should be checked regularly to ensure that the engine is in good working condition. Engines with electronic ignition advance differ from engines with vacuum and mechanical centrifugal advance in the adjustment of ignition timing. Please review the instructions carefully.

4. BATTERY

The battery supplies power to the ignition, starting system, lights and other electrical devices. When the engine is rotating, the engine charges the battery. After repeated charging, discharging and evaporation, the electrolyte in the battery will gradually decrease. Therefore, it is necessary to check the level and specific gravity of the electrolyte frequently and replenish the electrolyte in time.

Ignition system maintenance and repair 3

Electronic ignition system use and maintenance of the precautions are

1, electronic ignition system in the overhaul and installation, wiring must be correct, reliable, especially the polarity of the power supply can not be connected to the wrong, otherwise, it is very easy to damage the electronic ignition.

2, magnetic induction ignition signal generator of the two signal output line even if not divided into positive and negative poles, wiring can not be connected to the wrong, otherwise, it will lead to ignition time is not normal and can not be ignited.

3, the electronic ignition of the iron must be reliable, bad iron will lead to electronic ignition can not work properly.

4, the ignition signal generator output ignition signal line should be away from the high-voltage line, not to mention the ignition signal line and the high-voltage line entangled together, so as not to interfere with the normal operation of the electronic ignition.

5, when washing the car, should avoid splashing water on the electronic ignition and distributor, so as not to cause damage to the electronic circuit due to water.

6, when the engine is running, do not remove the cable on the battery pole stakes or check the generator power generation by fire test, so as not to produce instantaneous over-voltage and damage to the electronic components in the electronic ignition.

7, electronic ignition system in the ignition coil is usually a special high-energy ignition coil (primary winding resistance is small), maintenance needs to replace the ignition coil, should be replaced with the same type of ignition coil, can not be replaced with ordinary ignition coil.

8, high-voltage wire must be connected reliably and firmly. Because the highest secondary voltage of the electronic ignition system is very high, if the connection is not good, the high-voltage circuit is prone to open-circuit conditions, and its high open-circuit voltage (the highest secondary voltage) is prone to make the distributor cap and the ignition coil insulation is damaged by the breakdown.
