Ignition coil maintenance can not be ignored

In the opinion of many people, maintenance is nothing more than replacing consumables such as three filters and oil. In fact, during the operation of the vehicle, many parts are constantly worn out, and the scope of daily maintenance and inspection is far more than limited to three filters, oil, brake pads, spark plugs, etc. In many places, if you do not pay attention to inspection and maintenance, it may break down at any time.

Below are some components that are often overlooked in routine maintenance.
Many people know that spark plugs need to be replaced regularly, but they neglect the maintenance of other parts of the ignition system. The ignition high-voltage line is one of them. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition wire. Due to long-term work in a high temperature, dusty and vibrating environment, aging or even damage will inevitably occur. Therefore, like the spark plug, it is also a consumable that needs to be replaced frequently. The aging and damage of the ignition wire will greatly reduce the ignition energy, increase the fuel consumption of the engine, reduce the power, and cause serious misfire, which is a fatal failure for an engine with a three-way catalytic converter. According to foreign experience, even if there is no fault, the ignition high-voltage line needs to be replaced every 20,000 kilometers. Many domestic car owners often wait until the engine runs abnormally or even fails to start before considering checking the ignition system, but at this time, the fuel waste and engine wear caused by the potential damage to the ignition system components have far exceeded their value. In addition, distributor coverage, distributors, block ignition rails, automotive ignition coils, spark plugs and other components in the ignition system should also be included in routine maintenance inspections.

brake disc

The brake disc and the brake shoe are a pair of friction pairs. When the brake shoes wear, the brake discs also wear to a certain extent. The reason is very simple, but many people only pay attention to changing shoes when maintaining their vehicles. , but often neglected to replace the brake disc. The consequences of excessive brake disc wear are very serious. First, due to the decrease in surface flatness, the actual contact area becomes smaller, resulting in insufficient braking force; when the temperature rises rapidly, thermal recession is more likely to occur. All of these are very dangerous while driving. Some repair shops put severely worn brake discs on the lathe for surface treatment, commonly known as “discs”. This way, the surface is flat, but the disc is thinner, and the thermal decay under braking is more severe. In addition, the high temperatures generated during processing can anneal the brake disc, further reducing the mechanical strength. Generally speaking, after the brake shoes are replaced 2 to 3 times, the brake discs should also be replaced. Don’t be sad about these hundreds of dollars, after all, human life is priceless.

Generator bearing

Many repairmen are now nicknamed “stevedores,” meaning they can only replace parts, not repair. As long as some components are maintained according to the regulations, their life can be greatly extended, and the generator is one of them. A few years ago, generators were still expensive components in cars. At that time, there was a whole set of generator maintenance procedures in the maintenance procedures of automobiles, such as lubricating on time, replacing bearings, adjusting and replacing carbon brushes, adjusting contacts, etc. Click Clearance etc. Now with the reduction in the price of spare parts, the daily maintenance of generators is gradually neglected by people. If the bearings are checked and replaced according to the above regulations, the life of the generator can be extended by at least 1 times. Generally speaking, when the vehicle travels 60,000 to 80,000 kilometers, the generator should be overhauled. In addition, the bearings of water pumps, power steering pumps, and air-conditioning compressors should be checked regularly.

Component Connector

Except for a very few important electrical connectors on automobiles that use gold contacts, most of the other connectors use copper-zinc alloys. In general, its reliability is guaranteed, but if the car is exposed to high temperature and high humidity for a long time and runs in a bumpy environment, these joints may cause failures such as looseness, rust, and poor contact. Therefore, in the daily maintenance, you should focus on checking the connectors of the computers, sensors, nozzles and other components on the car. If looseness or corrosion is found, it can be treated with Vaseline, or replaced with a new renault pen.
