Cigarettes can not only be used to diagnose faults, but also can be used to make temporary emergency response when conditions are limited or tasks are particularly urgent.
Check valve tightness
The airtightness of valve and valve seat can be checked by blowing. Clean the ground valve and put it into the valve guide in order. Use your hand or a suitable tool (such as a screwdriver rod) to counter the valve. Then take a breath of smoke and blow the smoke to the cleaned intake manifold and exhaust manifold. The principle is that the nozzle fits 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 that the valve has good sealing performance, otherwise, it should be grinded again.
Check whether the oil way and air way are smooth
The method of blowing smoke can be used to check whether each oil passage of carburetor is smooth. There are many oil and vacuum pipelines in the carburetor, especially the imported carburetor, usually need to be blown through with compressed gas after cleaning the carburetor. However, it is difficult for the operator to judge which oil or vacuum pipelines are really blown through, and there are many repair phenomena. It is very easy to find out whether every oil way or air way is unblocked by using smoke blowing law.
For example, if a carburetor car does not have idle speed, disassemble and clean the carburetor, dry and blow through the carburetor with gas, blow out the smoke with a hose (such as the advance pipe of the vacuum distributor), first from the idle oil metering hole, then to the idle air hole, and finally the smoke leaks from the adjusting screw of the carburetor idle gas mixture, then the idle oil passage and air passage are smooth, otherwise, recheck it until the smoke is emitted Stop.
In the same way, the vent holes on the transmission, rear axle housing, steering gear housing and engine crankcase gas check valve (PCV) can also be checked by blowing smoke, and then they can be repaired or replaced according to the situation. If the above components are blocked, the internal pressure will rise, which is easy to cause oil leakage at relevant parts and lead to failure.
Cigarette ash can be used as abrasives cigarette ash is a better abrasives
When repairing carburetor of automobile, especially carburetor of imported automobile, we often encounter wear of triangle needle valve and it is not easy to buy. At this time, we can use cigarette ash with point oil as abrasives to grind triangle needle and triangle needle valve seat, which will achieve satisfactory results.
Tobacco can stop leakage
In case of water leakage in the water tank during driving, the tobacco can be used for emergency. First, clamp the radiator with large water leakage in the water tank with a pair of pliers, then unscrew the water filler cap of the water tank, remove the thermostat (to prevent blocking), then crush the cut tobacco, put it into the water tank from the water filler, finally start the engine, and run it with low, medium and high speed respectively, so that the cut tobacco will be absorbed in the water leakage of the core pipe of the water tank. When you see that the water leakage of the water tank is blocked, cover the water filler cap and drive. However, it should be noted that this can only be used as an emergency. After returning to the site, the water tank should be cleaned with high-pressure water and thoroughly welded.
In addition, can also be used when the arrival of tobacco should be eager to local small area bleeding. It's not uncommon to be engaged in automobile repair work, cut skin and flesh and shed blood. After bleeding, if the wound is covered with clean cigarette silk, it can temporarily stop bleeding and relieve pain.
Filter tip can be used as lubricating felt
The filter tip of the cigarette can temporarily replace the lubricating felt on the cam of the distributor. First, peel off the paper outside the filter tip on the cigarette head, insert a proper amount of filter tip wire into the original felt metal clip (pay attention not to be too tight or too loose), cut the exposed part with scissors, and then drop a few drops of oil on the substitute felt (i.e. silk wadding).
However, the following points shall be noted during operation:
Filter cigarettes shall be used. If cigarettes without filter are used, the cut tobacco may be blown into the parts. When smoking, pay attention to safety and fire prevention, and prevent the ash from scattering into the precision motion pairs.
