The car won't catch fire, the lights can be turned on, and the music can be listened to, but when it catches fire, it clicks, which is not the sound when it starts normally. What happened?

First, it is very likely that the battery is dead. If this is still the case after replacing the battery.

Suggested inspection:

1. Is the spark plug damaged?

2, whether the engine carbon deposit, clean the throttle, nozzle, etc.

3. Whether the air intake system is abnormal.

4. Whether the idle motor is abnormal, and whether the engine speed and idle speed are abnormal.

5. Oil problem. After opening this can of oil, go to a regular gas station to refuel and try the effect again.

Second, the battery is dead.

1. If you can't ask others for help, you can't find tools, and you don't have enough people, you can take the method of manual gear to boost the car. In some cases, the booster can't start the car, so we must find and wait for help. Automatic cars can't be boosted to start.

2. If you are in a place like a highway, or you don't have hands and tools around you, you have to turn to the emergency rescue center and ask them to send an emergency charging car for emergency charging, or send a trailer to tow the car to a nearby garage or garage for maintenance and charging.

3. If the car is at home and other inhabited places and the battery is dead, and you can't find a spare battery, you can charge the car battery yourself as long as you can find a charger. Depending on the situation, you can also remove the battery from the car and take it home for quick charging. Generally, ten minutes of fast charging is enough to start the car. Be careful when removing the battery to avoid damaging various terminals.

4. If there is a jump in your car, you can also ask for help from passing cars or relatives and friends and find a normal car for help. Connect the battery positive pole of the aided vehicle and the battery positive pole of the aided vehicle with jumper wires, then connect the battery negative poles of the two vehicles, and then ignite to start the aided vehicle, so that the vehicle can be started. After the car starts, disconnect the negative connection line first, and then disconnect the positive connection line.

If it is convenient to find a fully charged battery with the same voltage as the battery used in the car, you can start the car with an external battery. Connect the positive electrode of the car battery with the positive electrode of the fully charged battery, then connect the negative electrodes of the two, and then start the car with a light. After the car starts, disconnect the negative connection line of the battery first, and then disconnect the positive connection line.

Maintenance skills

Check the tightness of the valve.

Smoke blowing can be used to check the tightness of valves and valve seats. Clean the grinded valves, put them into the valve guide tube in turn, hold the valves by hand or with a suitable tool, and then take a puff of smoke, and blow the smoke to the cleaned intake manifold and exhaust manifold, with the principle that the mouth sticks to the manifold without air leakage. At the same time, observe whether there is smoke between the valve and the valve seat. If no smoke comes out, it means that the valve is well sealed, otherwise it should be re-ground.

Check whether the oil and gas paths are clear.

Smoke blowing can be used to check whether the oil circuit of carburetor is unblocked. Carburetors have more oil lines than vacuum lines, especially imported carburetors, which usually need to be purged with compressed gas after cleaning. However, it is difficult for operators to judge which is the oil circuit and which is the real gas circuit, and there are many cases of maintenance.

If the smoke blowing rule is used, it is very easy to find out whether the oil passages or air passages are unblocked. You can also use the smoke blowing method to check whether the ventilation holes on the transmission, rear axle housing, steering gear housing and engine crankcase gas check valve are unblocked, and then repair or replace them according to the situation. If these parts are blocked, the internal pressure will increase, which will easily lead to oil leakage of all related parts and lead to failure.

Ash can be used as abrasive. Ash is a better abrasive.

When repairing automobile carburetor, especially imported automobile carburetor, the triangular needle valve is often worn and difficult to buy. At this time, soot can be mixed with engine oil as abrasive to grind the triangular needle and the triangular needle seat, which will achieve satisfactory results.

Cut tobacco can stop clogging.

If the water tank leaks while driving, tobacco can be used for temporary emergency. First use pliers to flatten the radiator with large water leakage in the water tank, then unscrew the filler cap of the water tank and remove the thermostat. Then, the cut tobacco is crushed and put into the water tank from the filling machine. Finally, start the engine and run it at low, medium and high speed respectively, so that the cut tobacco put in can be absorbed at the water leakage of the water tank core pipe.

When it is observed that the water tank is blocked due to water leakage, cover the fuel filler cap and drive. But it should be noted that this can only be used as an emergency, and the water tank should be thoroughly cleaned and maintained with high-pressure water. Tobacco can also be used to temporarily relieve local small bleeding. It is not unusual to engage in auto repair, cut some meat and shed some blood. After bleeding, if you cover the wound with clean cigarette silk, you can temporarily stop bleeding and relieve pain.

The filter can be used as a lubricating felt.

Cigarette filter can temporarily replace the lubricating felt on the distributor cam. First, peel off the paper from the filter on the cigarette head, put a proper amount of filter wire into the original felt metal clip, cut off the exposed excess with scissors, and then drop a few drops of engine oil on the substitute felt.

Matters needing attention

1. If you want to use a cigarette with a filter, if you use a cigarette without a filter, cut tobacco may be blown into the parts;

2. Pay attention to safety and fire prevention when smoking, and at the same time prevent ash from flying into the precision sports pair.
