At the same time, many observers note a seemingly strange pattern. In the vicinity of the alien vehicles, only internal combustion engines are turned off, while diesel engines continue to work as if nothing had happened. What's the matter here? Why did the internal combustion engines not so "please" the UFO? Let's try to answer this question. To turn off the engine of a normally operating car, you must turn off the ignition, in other words, open the electrical circuit, on which the supply of an electric discharge to the motor itself depends. This is the easiest way to stop the engine.
You can also stop the engine by changing in any way the composition of the fuel supplied to the combustion chamber, or by destroying the engine by mechanical action. But, as far as we know, this does not happen, and after the UFO moves away a certain distance, the engines start working again, and the fuel does not change its characteristics. In addition, the lighting of the car, the luminosity of its headlights, the work of the radio system also come to normal, and after all, neither the headlights nor the radio have anything to do with the composition of the fuel. It remains only to assume that changes occur in the electrical circuits of the car, and this can occur as a result of the electric or electromagnetic influence of the UFO on the operation of the engine, and on the lighting and on the radio system of the car.
Today there are several hypotheses to explain these UFO effects. At one time, the idea was put forward of the effect on the operation of the above-mentioned car systems of fluctuating electromagnetic fields, which are capable of disrupting the sparking sequence in the combustion chamber, blocking the input circuits of the radio receiver and disrupting radio reception. But along with this, there are several more views, one of which is very convincing and simple.
This is the so-called tungsten effect. He explains all three effects associated with electromagnetic interference from UFOs.
