Abstract
An apparatus for controlling the injection of steam into the intake manifold of an internal combustion engine having an exhaust attachable evaporation plate supplied with water by a reservoir across a float bowl. A restrictor is placed in the line connecting the float bowl and evaporator. The evaporator plate defines a bore and is insulated from the exhaust pipe by a heat resistant gasket having an aperture of predetermined area. Boiling and steam generation are restricted primarily in the region between the gasket and line restrictor.
Claims6
Steam vaporization apparatus for use with an internal combusion engine having an intake manifold and an exhaust system including an exhaust pipe, said apparatus comprising:
- (a) evaporator means defining an evaporator chamber therein;
- (b) means for attaching said evaporator immediately adjacent said exhaust pipe in heat exchange relationship therewith;
- (c) a reservoir;
- (d) a liquid bowl connected to said reservoir and having a float valve associated therewith and an outlet, said float valve adapted to maintain the level in said bowl at or above said outlet;
- (e) first conduit means connecting said bowl to said evaporator whereby gravity flow of water is substantially continually induced from said reservoir to said evaporator chamber;
- (f) second conduit means connected to said evaporator chamber and in communication therewith connected to the internal combustion engine at the intake manifold thereby establishing a closed system from said reservoir to said manifold;
- and
- (g) flow restrictor means interposed between said float bowl and said evaporator chamber in said first conduit said flow restrictor means comprising a nozzle having a reduced flow passageway diameter whereby water delivered to said evaporatization chamber across said restrictor and is vaporized and delivered to the intake manifold and backflow of steam to the liquid bowl is restricted.
Steam evaporatization apparatus for use with an internal combustion engine having an intake manifold and an exhaust system including an exhaust pipe, said evaporatization apparatus comprising:
- (a) evaporator means defining an evaporator chamber therein, said evaporator means including a tee-fitting having at least first, second and third outlets, and an evaporator plate secured at said exhaust pipe having a bore therein and said evaporator plate engaging said tee-fitting at said third outlet;
- (b) means for attaching said evaporator immediately adjacent said exhaust pipe in heat exchange relationship therewith;
- (c) a reservoir;
- (d) a liquid bowl connected to said reservoir having a float valve associated therewith and an outlet, said float valve adapted to maintain the level in said bowl at or above said outlet;
- (e) first conduit means connecting said bowl to the said first outlet of the said tee-fitting whereby gravity flow of water is substantially and continually induced from said reservoir to said evaporator chamber.
- (f) second conduit means connected to the said second outlet of said tee-fitting and in communication therewith connected to the internal combustion engine at the intake manifold thereby establishing a closed system from said reservoir to said manifold;
- and
- (g) flow restrictor means interposed between said float bowl and said evaporator means in said first conduit said flow restrictor means comprising a nozzle having a reduced flow passageway diameter whereby water delivered to said evaporation chamber across said restrictor is vaporized and delivered to the intake manifold.
