Definitions

• the invention relates to a method for treating liquid fuel before combustion by exposure to an alternating electromagnetic field.
• liquid fuel and fuel preferably diesel oil
• a method of the type mentioned at the outset is designed in accordance with the invention in such a way that the electromagnetic field is generated by an electric current with a fundamental vibration of a frequency between 60 Hz and 150 Hz, which has at least one, preferably at least two, straight-line curve sections in each half-wave, and Integer harmonics of the fundamental oscillation are generated, the current preferably having a horizontal curve section in each half-wave, in particular in the form of a rectangular curve.
• the frequency of the fundamental oscillation is between 80 Hz and 120 Hz, preferably between 90 Hz and 110 Hz, there is a surprisingly high reduction in fuel or fuel consumption, which is above 10 compared to operation without exposure to an electromagnetic field % lies and which is optimally about 22%.
• the basic frequency that is optimal for the particular fuel or fuel also fluctuates. It is therefore expedient to have the basic frequency run through a frequency range periodically, for example with a period of 1 to 10 seconds, preferably 2 to 8 seconds and in particular 4 seconds to 8 seconds, this range being able to correspond, for example, to the frequency ranges mentioned above. In any case, this frequency range for currently commercially available diesel and heating oil and gasoline should contain the frequency 100 Hz, since this is obviously the optimal frequency or the optimal frequency is in the range close to 100 Hz.
• the multi-turn coil can be arranged surrounding the feed line to the injection nozzle of a diesel engine or an oil heating system.
• the multi-turn coil can be arranged surrounding the feed line to the carburetor or to the injection system of the four-stroke internal combustion engine.
• the coil does not necessarily have to be placed near the injector; it can also surround the supply line at another location, for example in the part of the line leading from the tank to the fuel pump.
• a standard BMW 520 T-Diesel was used for an experiment.
• the vehicle was operated on a performance roller dynamometer against normal driving resistance at 100 km / h after having been brought up to operating temperature by a long journey.
• the supply and return lines for the diesel fuel were separated between the engine and the tank, and both lines were inserted into a cylindrical measuring cup with an engraved scale division, which contained commercially available diesel oil (BP).
• BP diesel oil
• the graduations on the measuring scale were 4 mm apart, which corresponded to a measuring cup volume of 50 ml.
• the vehicle was initially started without modification of the engine and ran at medium speed until the suction and return lines were free of bubbles. The vehicle was then accelerated to 100 km / h and the measurement was started when this speed was reached. After an operating time of 3 minutes, the scale division of the measuring cup showed a fuel consumption of 5 graduation marks, i.e. 0.25 liters.
• the vehicle was equipped with coils which had approximately 30 turns, a coil being placed around each of the feed lines to the injection nozzle of each cylinder.
• the coils were connected to a supply circuit which fed the coils with a current of 4.5 mA, the current being in the form of a square wave with an amplitude of 2 V SS , which with a period of 6 sec had a frequency range from 0 Hz to Passed through 400 Hz.
• Example 1 The vehicle from Example 1 was driven on the one hand without coils generating electromagnetic fields and on the other hand with the coils applied in the manner described in Example 1 over a distance of 500 km, the same route being driven in both operating cases and the driving speed, within the scope of the possible, was kept the same.
• the fuel consumption was approximately 11 liters per 100 km, while the load on the coils was approximately 8.7 liters per 100 km.
• Example 1 The experiment from example 1 was repeated, but the coil was subjected to a square wave of constant frequency of 100 Hz. The reduction in fuel consumption was the same as in Example 1.
• Example 2 The experiment from Example 1 was repeated, but the coil was fed with a square wave with a current of 4.5 mA and an amplitude of 2 V SS , which ran through the frequency range from 0 Hz to 833 Hz with a period of 6 sec. The reduction in fuel consumption was only around 9%.
• Example 2 The experiment from Example 1 was repeated, the coil being subjected to a square wave with a frequency of 180 Hz. There was no reduction in fuel consumption.
• Example 2 The experiment from Example 1 was repeated, but the coil was subjected to a square wave with a frequency of 440 Hz. In this case, too, there was no reduction in fuel consumption.
• Example 2 The experiment was repeated as in Example 2 with a passenger car (Chrysler Voyager 3.0 LE) with a four-stroke engine with an injection system, the coil being placed around the supply line to the injection system.
• the coil was supplied with a current of 5 mA, which was in the form of a square wave with an amplitude of 3 V SS and a frequency of 100 Hz.
• the gasoline consumption Shell regular gasoline unleaded was measured with an electric flow meter.
• the vehicle was driven on the highway with no wind and about 5 ° C outside temperature with the set speed (cruise control) without and with the coil under power.
• the optimal effect could also be achieved with a different frequency, which, depending on the composition of the fuel, is less than or greater than 100 Hz, or even greater than 150 Hz could be. Knowing the present invention, the person skilled in the art has no difficulty in determining the optimum frequency.
