Smoke generator for checking the car intake from the soldering iron


Trouble happened, the Check Engine light on car, a scan by the scanner showed error 0505, air leaks, respectively, incorrect measurement of the amount of air by the electronics and improper mixture formation. In my car, this was expressed in unstable idling and sometimes freezing of revolutions, the engine did not reset to idle when refueling.

Checking by light spot spraying with a quick start to the intake manifold at idle showed that somewhere there is a hole, the speed increased, but the leakage could not be visually determined. Compressor injection of air under pressure into the intake manifold also showed a leak and narrowed the space a bit, but again, no specific location was found. I remembered about the smoke generator and fired up to do it yourself, which I bring to your attention.

The Internet is full of all kinds of examples, but they are mainly based on candles from diesel engines, nichrome wires and even cigarettes. Kapets. None of this was at hand, but a broken 40-watt Chinese soldering iron was lying around. The sting fell off at the point of attachment to the plastic handle, and besides, he did not want to regulate the temperature of the sting, he was overheating. It’s good that he didn’t throw it away, we only need a ceramic heating element and a power cord from it. There were no metal tubes either, I found plastic ones from a water filter, for the first time it will do.

For the manufacture I used:
1. A jar of baby food with a metal lockable lid,
2. A metal grid for washing dishes,
3. The heating element from the soldering iron,
4. A power cord with a plug from the same soldering iron,
5. A plastic tube, later replaced by 2 metal ones,
6. Cold welding.



By the way, I found the same heating element separately on Aliexpress, can someone come in handy.



To begin with, we mark the places of the holes, central for the rod, side for the tubes, through one we will supply air, the other end will be connected to the intake manifold.


We drill 3 holes for the diameter of the tubes and the rod from the soldering iron. It should be something like this.


Fitting a heating element.


... and pipes.


And all together in the bank.



The next stage, we fix the heating element, for this we wrap the very tip, which will be mounted on the cover with non-combustible material, I used a gasket from a powerful diode assembly from a broken computer power supply.



I wrapped the tip of the rod with this gasket and secured it with electrical tape.


The next step is to solder the network cable to the element.


To make contacts, he used soldering acid.




Class, you can solder the wires. First we put on a cambric wire, solder it.


We put on shrink cambric, heat it.


Same thing with the second contact.



We prepare for fastening in the lid of the can using cold welding.


Before using cold welding, it is advisable to soap your hands and let the soap dry a little, then the cold welding residues that stick to your hands can easily be washed off.




We put a metal mesh in the jar, it is better to use a rigid one. There is still a soft one on sale, it burned out in my place of contact with the rod.



After the hardening of cold welding, we try to work. In work I tried different liquids. Glycerin smokes best of all. The pharmacy sells in jars of 25 ml for 25 rubles, I needed 3.

I noticed that the heating rod does not heat up along the entire length, but only in the middle. And if the liquid comes into contact with this place, the smoke becomes more.




After many attempts with different fluids that I found at home, plastic pipes started to melt, by then I found metal pipes. The tubes from the telescopic antenna from the old receiver came up well.

Smoke begins to go about 10 seconds after switching on and its intensity does not decrease during purging.



When checking on a car, I found 3 places. The rubber tubes in a fabric braid cracked, although visually, to the touch and bending were in perfect condition, I would not have found it without a smoke generator.



Unfortunately, it was not possible to show other places, it is difficult to repair the car and remove at the same time. In conclusion, I’ll add that it’s probably not possible to use such a smoke generator in everyday car repair work, but it’s quite possible to fix your car.

Worked for 15 minutes (the glycerin in the jar is boiling, naturally the jar is heated) with short breaks to eliminate malfunctions. The metal tubes at the junctions with the glue gave a small leak, perhaps it was necessary to solder these places. But in general, I am pleased with the result. The error disappeared, the idle returned to normal, and freezes at higher speeds disappeared. And it felt like the car began to respond better to the brake pedal.

I shot some of the experiments on video:

X16XEL, I know about the XX regulator, but anyway I set it from Niva. Saving. There is also a clogged tube from a coal tank ventilation filter; the filter has been falling for a long time. It is connected through a valve. I tried to clean, it clogs again, I need to change the filter. It does not affect revolutions and driving.
There are still problems with the EGR valve and the XX regulator. But I shot them, cleaned them.

If the motor is X20XEV, then problems with idle are a given for him!)))). I had one on Omega. Especially often there the plug on the throttle clogs. And to clean it - ay-yay, how inconvenient. So, (rightly) very often the highway itself (corrugation) and the accompanying pipes seem strong and new, but in fact - air.
But washing the regulator XX is a waste of time! There the sleeve on the stock wears out. Which is in from the solenoid to the valve.Washing helps for a couple of days. Only a replacement! ... Yes ... And only Siemens walks. Others - don't even try ...

One tube of the smoke generator to the compressor (I connected the usual one, how do we pump the wheels). A second pipe to any intake manifold fitting. You close the bag with the pipe that goes to the air filter. Turn on the smoke generator, as soon as the smoke has gone, turn the compressor on / off, look around the intake manifold, nozzles, pipes that are connected, gaskets. The smoke went - in this place there is a hole or a crack, as in my case on the pipes. I inserted a small piece on the video, which turned out to be captured.
well, you puff this smoke into yourself and you can immediately see what is wrong with the tract
Everything is clear about the smoke generator. And how was the intake manifold itself checked?

Opel Vectra B 1996 release. On this machine, there are problems in the pipe between the throttle and the intake manifold, it is rubber. I thought a crack in it, so it was unexpected that the problems were in the tubes. They look almost like new. There are still problems with the EGR valve and the XX regulator. But I shot them, cleaned them.
