Automobile maintenance technology

1. Difficulty in starting the car

This situation is usually caused by the low voltage of the car battery, resulting in battery power loss. If conditions permit, you can use another car to dock it. After starting the fire, rarely idle or drive for half an hour to let the battery charge before turning off the engine. In addition, you can prepare a battery emergency starter in advance, so that you can solve it yourself when you encounter battery power loss. Remember, go to the maintenance point to check the battery immediately after the car starts.

2. Abnormal noise of wipers

This is usually caused by aging of the wipers or foreign objects stuck on them. It can usually be solved by grinding and cleaning with fine sandpaper and rags. If you find that the rubber on the wiper has hardened, it means that it has aged and cannot be replaced. It must be replaced with a new one. Otherwise, it will seriously affect driving safety when it rains heavily.

3. Tobacco repair

It is so embarrassing when the car is in the suburbs or far away from the repair shop and encounters a water tank leak. At this time, a pack of cigarettes can solve the problem. Sprinkle the tobacco into the car water tank, start the car, and wait for the coolant to circulate. The tobacco can block the leaking place of the water tank. Of course, this is also for small leaks.

4. How to reduce tire noise

When the wheel is stuck with stones, it will produce strange noises. In fact, it is very simple to lay a sound insulation pad on the inside of the wheel bag, or use a stone-clearing hook to pick out the stones on the tire one by one! It is recommended to adopt the latter solution. Although it is a bit troublesome, it is safer to drive.

5. How to extend the service life of the muffler

It is very simple and applicable. In the past, old models, due to the unreasonable arrangement of the original car exhaust, caused water erosion in the exhaust pipe. This can be solved by punching a small hole in the very bottom of the muffler.

6. Fuel tank damage

When the motor vehicle is in use, if the fuel tank is found to be leaking, the leaking area can be wiped clean, and soap or bubble gum can be applied to the leaking area to temporarily block it. When there is a car repair place, it must be professionally repaired. Remember: usually repair with epoxy resin adhesive.

7. Automobile engine shaking, fueling weakness

Engine shaking is generally caused by the different working conditions of the four cylinders (missing cylinders), which is caused by carbon deposits or aging of the ignition system. It can be solved by running at high speed or replacing and cleaning the carbon deposits in the engine. Note: If it is a problem of carbon deposits, you must pay attention to it, otherwise the engine will explode at the least, or even overhaul at the worst.

8. Paper can also repair cars

When the capacitor in the car ignition system is damaged, it will directly affect the engine's starting performance and acceleration performance, and even cause the car to fail to start. Under normal circumstances, the capacitor cannot be repaired after being damaged and can only be replaced. However, if the car is driving outside, in the case of capacitor damage, paper can play a great role in maintenance.

As we all know, capacitors are generally made of aluminum foil or insulating wax paper. Although it is small and the cost is low, the capacitor directly affects the engine's starting and ignition performance. If the capacitor is damaged during driving, you can use the retaining ring on the generator and starter, plus a few pieces of paper instead.

Specific skills: Place several layers of dry paper on the guard ring and the housing of the generator and starter to insulate the guard ring and the housing, and then connect two wires to the fastening bolts of the two guard rings. As the lead wire, use another wire, one end of which is connected to the two lead wires, and the other end is connected to the low-voltage terminal of the distributor.
