FIG. 2
I Q INVENTOR V M lid) BY AW DESCRIPTION OF INVENTION This invention relates to novel means for the removal of detrimental matter from the exhaust gases of internal combustion engines.
The principal object of the invention is to provide in such means a mixing device which is inserted in the exhaust pipe leading from the exhaust manifold of an internal combustion engine to the usual muffler, themixing device comprising a cylindrical drum having a substantially tangential inlet and an aligned substantially tangential outlet whereby the exhaust gases in passing through said exhaust pipe towards the muffler are given a whirling motion.
Into the drum of said mixing device is dropped a mixing liquid from a supply tank holding a quantity of water, phosphoris acid, peroxide of barium and peroxide of hydrogen. The mixing liquid dropped into the drum, disperses and evaporates by means of the heat of the gases exhausted from the engine. As this evaporated liquid cools down the inner part of the drum the exhaust gas which comes into the drum from the exhaust manifold is also cooled down and its volume decreases, and a low pressure condition occurs in the inner part of the drum. At the same time carbon monoxide, sulphurous acid gas, lead, hydrogenchloride, nitrogenoxide, carbon, dust, etc., are melted into the above mentioned evaporated mixed liquid, mingled into a compound with the vapor, and discharged from the exhaust gas outlet. The compound of the vapor and carbon monoxide, sulphurous acid gas, lead, hydrogenchloride, nitrogenoxide, carbon, dust, etc., which is discharged out of the outlet of the mixing device is dehydrated and separated by means of passing same beyond the muffler and through a dehydrating device in which calcium carbonate, etc., is contained, and which is connected to the rear end of the muffler, and the substantially pure air remained is discharged into the open air.
I will explain the invention with reference to the accompanying drawing, which illustrates one practical embodiment thereof, to enable others familiar with the art to adopt and use the same; and will summarize in the exhaust pipe between the manifold and muffler.
As shown in FIG. 2, the internal combustion engine l is provided with the usual exhaustmanifold 2. An exhaust pipe 3 connects the rear end of the intake manifold 2 with the inlet of a muffler 4. A dehydrating device 5 is connected by pipe 6 from the rear end of the muffler 4 to the inlet of the dehydrating device 5, which device exhausts through pipe 7 to the atmosphere.
In the pipe 3 is a mixing device shown more particularly in FIG. 2, the same consisting of a cylindrical drum 8 having a substantially tangential inlet 9 and an aligned substantially tangential outlet 10 whereby the exhaust gases entering the mixing drum 8 will give a whirling motion within the drum 8.
Extending laterally into the drum 8 at the side remote from the inlet 9 and outlet 10 is an orifice 8a (FIG. 1) receiving the end of a pipe 11 (FIG. 2) extending from a tank 12, which tank 12 holds a quantity of mixing liquid consisting of water, phosphoric acid, peroxide of barium and peroxide of hydrogen which is dropped from the pipe 11 into the drum 8.
In operation, when the engine 1 is in operation the mixing liquid from the tank 12 is dropped into the drum 8 and is dispersed and evaporates by means of the heat of the gas exhausted from the engine 1. As this evaporated mixing liquid cools down the inner walls of the drum 8, the exhaust gas which is whirling within the drum 8 and which comes into contact with the walls of the drum 8 is also cooled down, and its volume decreases, and a low pressure condition occurs in the inner part of the drum 8. At the same time carbon monoxide, sulphurous acid gas, lead, hydrogenchloride nishowing means for introducing the mixing liquid into trogenoxide, carbon, dust, etc., are melted into the above mentioned evaporated mixing liquid, mingled into a compound with the vapor and discharged from the exhaust gas outlet 10. The compound of the vapor and carbon monoxide, sulphurous acid gas, lead, hydrogenchloride, nitrogenoxide, carbon, dust, etc., which is discharged out of the outlet 10 is dehydrated and separated by means of passing from muffler 4 through the dehydrating device 5 in which calcium carbonate etc. is contained, and which device 5 is connected with the rear end of the muffler 4, and the pure air remaining in the dehydrating device 6 is discharged into the open air or atmosphere.
Each of the devices, i.e., the mixing device 8 of the exhaust pipe 3 which is characterized by its capacity of forming the compound of the detrimental matters in the exhaust-gas and the vapor into which the mixing liquid is transformed by the heat from the exhaust-gas which enters the drum 8, and the dehydrating device 5 of the detachable container which contains the dehydrator in which the chief ingredient is calcium, together form novel means for removal of detrimental matter contained in the exhaust gas of internal combustion engines.
