APPARATUS FOR UTILIZING EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE, MUFFLER AND SPARK ARRESTOR Filed Oct. 13, 1967 Sheet 2 of 2 United States Patent ABSTRACT OF THE DISCLOSURE An apparatus for utilizing exhaust gases of an internal combustion engine, muffler and spark arrestor having a tubular casing with a helical partition mounted therein so as to form a spiral passageway. An inlet pipe at the front of the casing delivers exhaust gases from an engine to the spiral passageway, and as these gases are whirled through the passageway, the heavier and lighter components thereof are divided into separate streams, and the lighter components of the centrifuged gases are conveyed to a carburetor to augment the engine operating charge, while the heavier components are recycled through the spiral passageway to recover additional lighter components that are delivered to the carburetor. An outer housing is provided to serve as a muffler and to collect ignited fragments contained in the exhaust gases so that they will be extinguished without escaping to the atmosphere.
Summary It is proposed in this invention to provide an improved apparatus for utilizing exhaust gases of an internal combustion engine by more etficiently separating the heavier expended inert components from the lighter combustible components, and recycling the heavier components so as to recover any additional lighter components therefrom, and to convey substantially all of the lighter components of the centrifuged exhaust gases to the carburetor.
Moreover, it is proposed to provide an outer housing that is provided with a sump on its underside for collecting ignited fragments contained in the exhaust gases so that these fragments will be confined in the sump and will be extinguished without escaping to the atmosphere. This outer housing forms part of the recycling system for the heavier components of the centrifuged exhaust gases, and perforated partitions are provided in a compartment of this housing so as to substantially reduce the noise of the exhaust gases.
Other objects and advantages will appear as the specification proceeds, and the novel features of the invention will be pointed out in the appended claims.
Brief description of the drawings For a better understanding of the invention, reference should be had to the accompanying drawings, forming part of this specification, in which:
FIG. 1 is a top plan view of my apparatus for utilizing exhaust gases of an internal combustion engine, muffler and spark arrestor;
FIG. 2 is a transverse sectional view taken along the plane 2-2 of FIG. 1;
FIG. 3 is a fragmentary sectional view taken along the plane 33 of FIG. 2; and
FIG. 4 is a longitudinal sectional view taken along the plane 4-4 of FIG. 1 on ane'nlarged scale.
While only the preferred embodiment of the invention has been shown, it should be understood that various changes, or modifications, may be made within the scope "ice of the appended claims without departing from the spirit thereof.
Description of the preferred embodiment Referring now to the drawings in detail, it will be noted that a tubular casing A is provided and its front end 10 has an inlet pipe 11 attached thereto, this pipe being connectible to an exhaust pipe of an internal combustion engine so that exhaust gases from the engine will be delivered to the interior of the casing. The latter is further provided at its rear end 12 with an outlet pipe 13 leading to the atmosphere.
As shown in FIGS. 2 and 4, a helical partition B defines a plurality of convolutions 14 mounted in the tubular casing A and coacting therewith to form a spiral passageway C extending longitudinally of the casing, this spiral passageway communicating with the inlet pipe 11 so as to receive a rapid flow of exhaust gases therefrom, whereby heavier and lighter components D and E, respectively, will be separated from one another by centrifugal force into outer and inner streams, respectively, as the exhaust gases whirl along the spiral passageway as indicated by the arrows 15.
The heavier components D of the exhaust gases are combustibly inert water vapor, carbon dioxide and nitrogen, while the lighter components E contain hydrogen, methane and carbon monoxide which may be employed efliciently to augment the engine operating charge. The lighter components E are conveyed by an outlet pipe 16 to a carburetor (not shown), as suggested by the legend TO CARBURETOR in FIG. 1. The details of this arrangement will be set forth as the specification continues.
As the specification proceeds, it will be apparent that means are operable for recycling the heavier components D of the centrifuged exhaust gases through the spiral passageway C for recovering additional lighter components E of the exhaust gases that may be mixed therewith, whereby these additional lighter components may be conveyed to the carburetor. The outlet pipe 13 communicates with the spiral passageway C for receiving the purified gases and conveying them to the atmosphere.
For the purpose of withdrawing the lighter components E of the centrifuged exhaust gases, the convolutions 14 of the helical partition B is provided with an axial passageway 17 (see FIGS. 2 and 4) extending therethrough from front to rear thereof, and through which the lighter components B may flow rearwardly, as suggested by the arrows 18. Also, a spiral conduit 19 is carried by the convolutions 14 of the helical partition B and extending from the rear of the latter toward the front end 10 of the tubular casing A.
As illustrated in FIGS. 2 and 4, a substantially axial deflector 20 is mounted adjacent to the rear portion of the helical partition in a position to scoop into and deflect the lighter components E of the centrifuged exhaust gases from the axial passageway 17 into the spiral conduit 19, as suggested by the arrows 21 in FIGS. 2 and 4, these components passing through a slot 22 formed in a fitting 23 that is secured in the rear portion of the axial passageway .17. The rear end 24 of this fitting is closed (see FIG. 4).
The outlet pipe 16 previously mentioned extends from the front end of the spiral conduit 19, and thus the lighter components E of the centrifuged exhaust gases will be delivered to the engine carburetor.
The means for recycling the heavier components D of the centrifuged exhaust gases will now be described. It will be noted that an outer housing F surrounds the tubular casing A and is spaced therefrom to form a compartment G therebetween (see FIGS. 1, 2 and 4). A first lateral deflector 25 is carried by the tubular casing A to extend lengthwise thereof in a position to scoop into and deflect the heavier components D outwardly from the spiral passageway C into the compartment G, as suggested by the arrows 26, these heavier components passing through a slot 27 formed in the tubular casing A (see FIG. 2). This slot extends substantially from the rear end 12 of the tubular casing to a point 28 spaced rearwardly from the front 10 of the casing (see FIG. 1).
Moreover, a second lateral deflector 29 is carried by the tubular casing A to extend lengthwise thereof in .a position to scoop into and deflect the heavier components D of the centrifuged exhaust gases inwardly from the compartment G and back into the spiral passageway C, as suggested by the arrows 30, these components flowing through a slot 31 formed in the tubular casing A (see FIG. 2). The second lateral deflector 29 extends substantially from the front end 10 of the tubular casing to a point 32, but does not overlap the first lateral deflector 25. As shown in FIG. 1, the first and second lateral deflectors 25 and 29, respectively, are disposed on opposite lateral sides of the tubular casing A.
Thus the heavier components D that enter the compartment G through the slot 27 must return toward the front end 10 of the tubular casing A before passing through the slot 31, as suggested by the arrows 33 in FIG. 4. This will permit heavy particles of the centrifugated exhaust gases to collect in a sump H on the underside of the housing F. Accordingly, ignited fragments contained in the exhaust gases, for instance, carbon, lead oxides and water will be confined in the sump H and will be extinguished without escaping to the atmosphere, and this feature constitutes the spark arrestor of the invention.
Turning now to FIGS. 2 and 4, it will be observed that perforated partitions 34 are provided in the compartment G between the tubular casing A and the outer housing F so as to substantially reduce the noise of the exhaust gases and, therefore, the mufller feature of the invention is provided. These partitions, also, serve to hold the tubular casing A and the outer housing F in spaced relation with respect to one another.
In FIG. 4, a removable inspection plate 35 has been designed which may be periodically taken off to allow the amount of accumulations in the sump H to be determined.
The outlet pipe 16 may be connected to the intake manifold of the engine, if desired, instead of to the carburetor.
