1. It is very likely that the battery is out of power. If the problem is still the same after replacing the battery.

It is recommended to check:

1. Whether the spark plug is damaged

2. Whether the engine has carbon deposits, clean the throttle valve, oil nozzle, etc.

3. Is the air intake system abnormal?

4. Is the idle motor abnormal? The engine speed and idle speed are abnormal.

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

2. Solution to a dead battery

1. If we cannot ask for help from others, cannot find tools, and have enough manpower, we can use boosting for manual transmission cars. method to start the car. In some cases, even the boost cannot start the car, and one has to search and wait for rescue. Automatic cars cannot be boosted to start.

2. If you are on a highway or other places, or if there are no manpower or tools around you, you can only ask the emergency rescue center to send an emergency charging vehicle for emergency charging or a tow truck. The car is towed to a nearby repair shop or repair shop for repair and charging.

3. If the battery of the car is out of power in a place where people live, such as at home, and a spare battery cannot be found, you can charge the car battery yourself as long as you can find a charger. Depending on the situation, you can also charge the car battery. Remove the battery from the car and take it to your home for fast charging. Generally, ten minutes of fast charging is enough to start the car. Be careful not to damage the various terminals when removing the battery.

4. If your car is equipped with jumper cables, you can also ask for help from passing cars or relatives and friends, and find a normal car to come over and help. Use jumper wires to connect the positive terminal of the battery of the car being assisted to the positive terminal of the battery of the car to be assisted, then connect the negative terminals of the batteries of the two vehicles, and then ignite the vehicle being assisted to start the car. After starting the car, disconnect the negative cable first, then the positive cable.

5. If you can easily find a fully charged battery with the same voltage as the battery used in the car, you can use an external battery to start the car. Connect the positive terminal of the car's battery to the positive terminal of the fully charged battery, then connect the negative terminals of the two, and then start the car. After starting the car, disconnect the negative battery cable first, then the positive cable.

Maintenance tips

Check the valve sealing

You can use the smoke blowing method to check the sealing of the valve and valve seat. Clean the ground valves and put them into the valve guide in order. Hold the valve with your hand or a suitable tool, then take a puff of smoke and blow the smoke into the cleaned intake and exhaust manifolds. The principle is that the mouth fits the mouth of the manifold without leakage. At the same time, check whether there is smoke coming out between the valve and the valve seat. If there is no smoke coming out, it means the valve has good sealing, otherwise it should be reground.

Check whether the oil and air passages are smooth

You can use the smoke blowing method to check whether the oil passages of the carburetor are clear. Carburetors have many oil and vacuum lines, especially imported carburetors. Usually, compressed gas needs to be blown through after cleaning the carburetor. But which oil channels or vacuum channels are actually blown through, the operator is very confused. It is difficult to judge, and it causes a lot of repairs.

If you use the smoke blowing method, you can easily find out whether each oil passage or air passage is smooth. 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 smooth, and then repair or replace them according to the situation. If the above components are clogged, the internal pressure will increase, which may easily lead to oil leakage from relevant parts and cause failure.

Cigarette ash can be used as an abrasive. Cigarette ash is a better abrasive

When repairing car carburetors, especially those of imported cars, triangles are often encountered. The needle valve is worn and not easy to buy. At this time, you can use cigarette ash mixed with some engine oil as an abrasive to grind the triangular needle and triangular needle valve seat, which will achieve more satisfactory results.

Shredded tobacco can block leaks

If you encounter a water tank leak while driving, you can use shredded tobacco as a temporary emergency.

First, use pliers to flatten the leaky radiator of the water tank, then unscrew the water tank water inlet cap, and remove the thermostat at the same time. Then crush the tobacco and put it into the water tank from the water inlet. Finally, start the engine and use Run at low, medium and high speed, so that the inserted tobacco will be adsorbed on the leaking part of the core tube of the water tank.

When you see that the water tank is leaking and blocked, close the water filler cap and you can drive. But it should be noted that this can only be used as an emergency. The water tank should be cleaned with high-pressure water and thoroughly welded and repaired later. Cut tobacco can also be used to temporarily deal with small localized bleeding. When working in auto repairs, it is not uncommon to get some cuts and blood. After bleeding, if you use clean cigarette shreds to cover the wound, it can temporarily stop bleeding and analgesia.

The filter tip can be used as a lubricating felt

Using a cigarette filter tip can temporarily replace the lubricating felt on the distributor cam. First, peel off the outer paper from the filter tip on the cigarette tip, stuff an appropriate amount of filter tip wire into the metal clip of the original felt, and cut the excess part with scissors, and then put a few drops of engine oil on the substitute felt.

Notes

1. Use filtered cigarettes. If you use cigarettes without filters, the tobacco may be blown into the parts;

2. Smoking Attention should be paid to safety and fire prevention during operation, and at the same time, prevent soot from scattering into the precision motion pair.
