How to make a smoke generator for cars with their own hands?

A car is a whole complex of different systems and units, the work of which is closely interrelated. Therefore, any vehicle is not insured against unforeseen breakdowns. In case of occurrence of such malfunctions the car necessarily goes on diagnostics. Often under this word, drivers mean checking the machine using a computer tester. But this is not always true - sometimes the cause of the breakdown is so simple that you can cope with it without leaving home. But if this problem concerns the imperfection of any system, here it is necessary to buy a smoke generator for cars. The price for similar devices is about 5-6 thousand rubles. But you can go another way. To save a decent amount of money is quite feasible, by making a smoke generator for cars with their own hands. What is this tool and how is it made? The answers to these questions will be found in the course of our today's article.

Characteristics and purpose

In general, a smoke generator for cars (with their own hands made, or factory - it does not matter) is used to effectively inspect for leaks in different engine components. This may be an exhaust system, an air intake, a cooling system or some other system in which leakage is not allowed during operation. Also, this device is used to detect punctures in the tires or to check the tightness of the optics (often in such cases it "sweats"). The principle of the smoke generator is based on the use of thick smoke (most often white color), supplied under pressure of 0.3-0.5 bar per system and allowing to identify any leaks with minimal effort that could not be determined with the naked eye.

How to make a smoke generator for cars? Cooking tools

For the manufacture of this device we will need:

1. Air blowing gun.
2. Cigarettes.
3. Source of compressed air.
4. Pressure regulator.

All these parts can be purchased at any tool store. As a penultimate element (a source of compressed air) it is recommended to use any compact compressor. As an alternative, in this case a balloon wheel is suitable.

Getting Started

The blowing gun will have to be upgraded a bit. The inner hole where the cigarette will be inserted (the spout of the instrument) should have a diameter of 8-8.3 millimeters. If this value is less, use a drill to drill a hole to the above parameters.

Next, connect the air pressure regulator with the already modified gun. We also connect the source of compressed air. It should be noted that the output pressure should not be too large, so the compressor can choose the weakest. It may be necessary to vary the flow of air to get the most optimal smoke output. The pressure itself should not exceed 0.5 bar. If this value is greater, it will be more difficult to diagnose details for leaks, because you will have to stock up a whole set of cigarettes.

Then everything is simple. We insert a cigarette into the nose of the gun, set it on fire and screw it into the first tool. Everything, at this stage, the smoke generator with their own hands has been successfully manufactured!

You can use a different, more complicated method of manufacturing this diagnostic equipment. Thus, we will provide the car with almost a professional diagnosis for leaks.

We make a smoke generator for a car with our own hands - a method №2

Unlike the first method, the device of such a smoke generator will be more expensive to manufacture. But in the end we get a much larger smoke output, so the device will be more convenient to use.

Upgrade the syringe-lubricant

For the basis of the construction we take the housing from the syringe-lubricant. It can be purchased for about 300-500 rubles. As in the first case with a gun, the syringe will have to be modified by hand. In the middle of the device, it is necessary to mount the bulkhead-adapter. On one side of it the spark plug is screwed in. The latter can be taken from any domestic diesel engine (for example, from MMZ D 240 or 245, which is installed on the ZIL "Bychok"). The voltage of the glow plug must correspond to 12 or 24V. For the first, a power limiting scheme must be applied. The simplest and cheapest option is to use the relay turns. Thanks to this detail, the candle's operation time is almost halved.

The second part of the work

How is the smoke generator for the car manufactured by yourself? Next, you need to drill a few holes in the top cover of the syringe. They will be necessary for us to supply air from one side and to exit the smoke from the other. At the inlet, it is necessary to install a pressure regulator, which will provide an oxygen flow of no more than 0.2-0.3 atmospheres. A non-return valve is mounted on the outlet hose. It can be taken from the carburetor engine power supply system. As for the use of oil, anyone can be used to diagnose, however, Johnsons baby, glycerine or liquid for concert smoke installations are usually used. Everything, at this stage, the smoke generator for cars with their own hands has been successfully manufactured. As you can see, in just a few minutes you can create a device similar in its functional to the professional, whose cost is 5-6 thousand rubles.

So, we found out how to make a smoke generator with our own hands and what tools and materials are required for this.
