2. Embodiments An embodiment of the present invention will be described below with reference to the accompanying drawings. The reactor 10 includes a tubular exhaust gas expansion chamber 12 made of a thin plate and having a cylindrical shape. Expansion chamber 12 is approximately 45.7z
(18 inches) in length and approximately 12.7α (5 inches) in diameter.

This size can be adjusted to the value required for the vehicle.

The expansion chamber 12 is provided with a front closing member 14 . The closure member 14 is fastened to the expansion chamber 12 by fasteners or by welding. Further, the expansion chamber 12 is provided with a similar rear closing member 16. A central opening 17 is formed in the front closing member 14 . The central opening 17 is adapted for introducing and locating a longitudinally and axially extending metal exhaust gas diffuser barrel 18 inside the expansion chamber 12 . Exhaust gas diffuser barrel 18 is approximately 45.7cm (1
8 inches) to about 48.3 crIK (19 inches) and extend axially along the length of the expansion chamber 12. The exhaust gas diffuser barrel 18 is adapted to be connected to an exhaust gas emission source of an internal combustion engine by a suitable connecting pipe (not shown).

The exhaust gas diffuser barrel 18 is approximately 2.5 cm (1
inch) to 3.8 cm (11/2 inch) in diameter and the exhaust gases to be released are
It is provided with a plurality of discrete openings 15 for diffusion and expansion within the interior of the tube. The end of the exhaust gas diffuser barrel 18 is indicated at 20 and is closed as follows. The exhaust gas diffuser barrel 18 is a silencer for reducing the noise of the emitted exhaust gas, i.e.
Performs the function of a muffler. Four air intake tubular members, namely air intake tubes 22, are formed in the front closure plate 14.
It is introduced longitudinally through additional openings 23 and is welded thereto. Air intake pipe 22 is 1
．． It is preferably 9 an (/4 inch) in diameter, and about 5.1 cIn (2 inch) to 7.6 cIn (2 in.) to 7.6 cIn.
It extends to a length of m (3 inches).

These air intake tubes 22 are arranged substantially concentrically with and spaced apart from four corresponding tubular exhaust gas discharge tubes 24 . The exhaust gas discharge pipe 24 extends longitudinally and projects through a corresponding opening 26 formed in the rear closure member 16. These exhaust gas discharge pipes 24 are fixed to the rear closing member 16 by welding or screwing.
Each tubular exhaust gas discharge tube 24, the front end of which is spaced from the front closure member 14 thereby forming a first passageway 35, has a diameter of approximately 2.5 cTn (1 inch). Accordingly, the diameter of each of the tubular air intake pipes 22 is smaller than the diameter of the corresponding tubular exhaust gas discharge pipe 24, thereby providing a gap between the air intake pipe 22 and the exhaust gas discharge pipe 24. A throttle passage 36 is formed in which the first air passage 35 communicates with the first air passage 35 through the flow of gas. A low pressure region due to the Venturi principle occurs at the discharge end of the air intake tube 22, thereby reducing the pressure of the exhaust gas to approximately 5.6 9/an
” (80 pounds per square inch) to approximately 0.569/
cIn" (8 pounds per square inch). Therefore, due to the low pressure area, the expansion chamber 1
The exhaust gas from 2 passes through the first passage 35 and the throttle passage 3.
6 into the low pressure region. At the same time, the atmosphere flowing through the air intake tube 22 is heated due to the exhaust gas flowing through the throttle passage 36 as well.

An atmosphere of 1.03 kli'/cIn2 (14.7 pounds per square inch) is forced toward a low-pressure region of 0.56 kg/Crn" (8 bonds per square inch) caused by Venturi action. The flowing and preheated air mixes with the exhaust gas discharged from the de-use barrel 18, so that the unburned fuel in the exhaust gas burns with the aid of the oxygen in the incoming air, causing it to The antithermal reaction converts CO to CO2.

Hydrocarbons also oxidize and burn, and nitrogen oxides are also reduced.

As mentioned above, heat is generated by the conversion of CO to CO2 due to the antithermal reaction of oxygen mixed in the air, and as a result, the exhaust gas discharge pipe is moved at a rate that is greater than the velocity of the exhaust gas released. The air will expand by the volume passing through 24. The expansion and velocity of the air passing through the exhaust gas discharge pipe 24 generates a thrust that provides additional power and acceleration to the vehicle by reducing the load on the engine. In this way, it imparts a thrust to the exhaust gas in an advantageous manner, reduces unburned impurities in the emitted exhaust gases, acts as a silencer, i.e., a muffler, and further reduces the amount of combustion gases from the engine. 0 This embodiment can guarantee the removal of 4 air intake pipes 2
Although two and four tubular exhaust gas discharge tubes 24 are shown, a plurality of such tubular tubes could be used.

A tubular exhaust gas discharge pipe 24 is disposed surrounding the exhaust gas diffuser barrel 18 so that exhaust gas discharged from the engine flowing into the diffuser barrel 18 is expanded within the expansion chamber 12. and is drawn into said tubular exhaust gas discharge pipe 24 by Venturi action, while reacting with the air drawn through said tubular air intake pipe 22 to produce substantially non-contaminating exhaust gases. 04 tubular air intake pipes 22 are inserted through the front closure member 14 and are spaced apart from each other and arranged concentrically with respect to the respective tubular exhaust gas discharge pipes 24 to define a low pressure region. ing. The exhaust gas diffuser barrel 18 is closed at its end remote from the inflow side and is spaced from the rear closure member 16 . The exhaust gas diffuser barrel 18 is the rear closing member 16-! Each of the six exhaust gas discharge tubes 24 extends beyond the rear closure member 16 to form a flared outlet in the form of a funnel 32, although the exhaust gas discharge tubes 24 can be extended and seal welded. Furthermore, each of the tubular air intake tubes 22 projects forward of the front closure member 14 and is formed in the shape of a funnel 34 . The new reactor generates thrust when the emitted exhaust gases generate the power to push the vehicle forward, removing harmful pollutants from the exhaust gases emitted by internal combustion engines. reduce the load on the engine during this period. The reactor 10 advantageously removes harmful contaminants, such as -carbon oxides, hydrocarbons. It is not necessary to use a catalytic converter to reduce nitrogen oxides in the exhaust gas emitted by an internal combustion engine, and there is no need to use a compressor, air pump or positive displacement blower to reduce nitrogen oxides in the emitted exhaust gas. There is no need to inject air into it. Furthermore, in this reactor there is no need to provide a separate silencer.Also, this reactor guarantees the removal of one combustion gas.An excessive amount of air enters the reactor and is heated by the exothermic reaction. The engine begins to expand, and as a result, it flows into the surrounding atmosphere together with the exhaust gas released from the engine, generating a considerable amount of thrust.
The load on one engine is therefore reduced by 5% to 7 inches due to the additional thrust generated in this way.

The use of this reactor is economical as it saves the cost of a silencer, i.e. a muffler, which becomes unnecessary during use.Thus, the heated exhaust gas passes through the opening 15. It is discharged uniformly and heats the exhaust gas discharge pipe 24 over its entire length as it passes through the passage 35. All unconverted carbon oxides from the low pressure region are therefore burned in the mixture gas passage through the heated exhaust gas discharge pipe 24. Furthermore, the air-fuel mixture is continuously heated as it flows through the exhaust gas discharge pipe 24, thus ensuring a thrust at the exit.
