a hose section, operably connected to the inlet region; and an outlet region, operably connected to the hose section, and operably configured to be further connected to an opening in the at least one side wall of an enclosure. ### Claim 2 (depends on 1) The exhaust apparatus according to claim 1, wherein the inlet region comprises: a magnet cap, having a bell with an opening therein and a hollow cylindrical neck connected to the bell and aligned with the opening, and a magnet, disposed in the bell, the magnet having an aperture therethrough which is aligned with the opening and the neck, the magnet cap and magnet enabling magnetic positioning of the inlet region on an engine, proximate to the exit opening of the exhaust system component for receiving an exhaust stream therefrom. ### Claim 3 (depends on 2) The exhaust apparatus according to claim 2, wherein the inlet region further comprises: a skirt, operably connected to the neck of the magnet cap, the skirt having a leading edge which circumferentially surrounds the neck so as to define an air gap therebetween, for enabling gases other than exhaust gases, which may be surrounding the inlet region, to be drawn in and entrained with exhaust gases passing through the neck, for mixture with and cooling of the exhaust gases. ### Claim 4 An enclosure system for an engine-powered apparatus, comprising: an enclosure, having at least two side walls; an exhaust apparatus, for facilitating passage of exhaust gases created by an engine of an engine-powered apparatus which has been positioned within the enclosure to a position exterior to the enclosure, wherein the exhaust apparatus further comprises an inlet region, operably configured to be releasably positioned proximate to an exit opening of an exhaust system component of an engine of an apparatus which has been positioned within the enclosure; a hose section, operably connected to the inlet region; and an outlet region, operably connected to the hose section, and operably configured to be further connected to an opening in one of the least two side walls of the enclosure. ### Claim 5 (depends on 4) The enclosure system according to claim 4, wherein the inlet region comprises: a magnet cap, having a bell with an opening therein and a hollow cylindrical neck connected to the bell and aligned with the opening, and a magnet, disposed in the bell, the magnet having an aperture therethrough which is aligned with the opening and the neck, the magnet cap and magnet enabling magnetic positioning of the inlet region on an engine, proximate to the exit opening of the exhaust system component for receiving an exhaust stream therefrom. ### Claim 6 (depends on 5) The enclosure system according to claim 5, wherein the inlet region further comprises: a skirt, operably connected to the neck of the magnet cap, the skirt having a leading edge which circumferentially surrounds the neck so as to define an air gap therebetween, for enabling gases other than exhaust gases, which may be surrounding the inlet region, to be drawn in and entrained with exhaust gases passing through the neck, for mixture with and cooling of the exhaust gases. ### Claim 7 (depends on 4) The enclosure system according to claim 4, wherein the enclosure further comprises: a fan, operably mounted to one of the at least two side walls; an aperture, through the one of the at least two side walls and aligned with the fan, the fan being oriented so as to draw ambient air into the enclosure when in operation, the fan being operably connectable to an engine of an apparatus which has been positioned within the enclosure, to derive actuation and power therefrom. ### Claim 8 (depends on 7) The enclosure system according to claim 7, further comprising at least one vent opening disposed in a side wall of the enclosure. ### Claim 9 (depends on 8) The enclosure system according to claim 8, further comprising a louver mounted in the at least one vent opening. ### Claim 10 (depends on 9) The enclosure system according to claim 9, wherein the louver is rotatable. ### Claim 11 (depends on 4) The enclosure system according to claim 4, wherein the inlet region is attached to the hose section by a removable clamp. ### Claim 12 (depends on 4) The enclosure system according to claim 4, wherein the outlet region is attached to the hose section by a removable clamp. ### Claim 13 (depends on 1) The exhaust apparatus according to claim 1, wherein the inlet region is attached to the hose section by a removable clamp. ### Claim 14 (depends on 1) The exhaust apparatus according to claim 1, wherein the outlet region is attached to the hose section by a removable clamp. ### Claim 15 (depends on 6) The enclosure system according to claim 6, wherein the skirt of the inlet region is attached to the neck of the magnet cap by a wire framework. ### Claim 16 (depends on 3) The exhaust apparatus according to claim 3, wherein the skirt of the inlet region is attached to the neck of the magnet cap by a wire framework. ### Claim 17 (depends on 1) The exhaust apparatus according to claim 1, wherein the hose section is operably configured to be articulatable, so as to enable positioning of the inlet region proximate an exit opening of an exhaust system of an engine, without requiring affixation of the inlet region to any portion of the engine. ### Claim 18 (depends on 4) The enclosure system according to claim 4, wherein the hose section is operably configured to be articulatable, so as to enable positioning of the inlet region proximate an exit opening of an exhaust system of an engine, without requiring affixation of the inlet region to any portion of the engine. ### Claim 19 (depends on 1) The exhaust apparatus according to claim 1, wherein the inlet region comprises: an inlet nozzle, operably configured to be positioned adjacent an exhaust structure of an engine for receiving an exhaust stream therefrom; and a skirt, operably connected to an exit portion of the inlet nozzle, the skirt having a leading edge which circumferentially surrounds the exit portion of the inlet nozzle so as to define an air gap therebetween, for enabling gases other than exhaust gases, which may be surrounding the inlet region, to be drawn in and entrained with exhaust gases passing through the inlet nozzle, for mixture with and cooling of the exhaust gases. ### Claim 20 (depends on 4) The enclosure system according to claim 4, wherein the inlet region comprises: an inlet nozzle, operably configured to be positioned adjacent an exhaust structure of an engine for receiving an exhaust stream therefrom; and a skirt, operably connected to an exit portion of the inlet nozzle, the skirt having a leading edge which circumferentially surrounds the exit portion of the inlet nozzle so as to define an air gap therebetween, for enabling gases other than exhaust gases, which may be surrounding the inlet region, to be drawn in and entrained with exhaust gases passing through the inlet nozzle, for mixture with and cooling of the exhaust gases.
