- ABSTRACT Disclosed herein is an exhaust gas manifold comprising an exhaust gas passageway including an exhaust gas inlet portion, an elbow portion extending downwardly from the inlet, a discharge portion extending downwardly from the elbow portion, a water jacket extending around the inlet and elbow portions of the exhaust gas passageway, and means for discharging coolant water from said water jacket and including means for maintaining the water jacket full of coolant.
- the invention relates generally to marine engines and, more particularly, to exhaust gas manifolds for multicylinder marine engines. Still more particularly, the invention relates to water-jacketing arrangements for such exhaust gas manifolds.
- the invention provides an exhaust gas manifold comprising an exhaust gas passageway including an exhaust gas inlet portion which generally extends horizontally and is adapted to communicate with the exhaust ports of an engine, and an elbow portion extending downwardly from the inlet portion to provide a smooth exiting passage for exhaust gases, together with a cooling jacket extending around the inlet and elbow portions of the exhaust gas passageway, and means for discharging coolant from the jacket and including means for maintaining the jacket full of water.
- Such means comprises a high rise tube which extends above the top of the jacket.
- the invention also provides an exhaust gas manifold comprising an exhaust gas passageway including an inlet portion, an elbow portion extending downwardly from the elbow portion, and a discharge portion extending downwardly from the elbow portion.
- the exhaust gas manifold includes a first coolant jacket extending around the inlet and elbow portions of the exhaust gas passageway and including therein a port, together with a second coolant jacket extending around the discharge portion of the exhaust gas passageway and including therein a port, and means for discharging coolant from the first jacket to the second jacket and including a coolant passage communicating .between the ports and including means for maintaining the first coolant jacket full of water.
- such means comprises a high rise tube .which extends above the top of the first coolant jacket in a non-cooling relationship to the exhaust gas passageway.
- an exhaust gas manifold which includes a smooth flowing exhaust gas passageway with an elbow which bends downwardly from an exhaust gas inlet portion communicating with the engine exhaust ports, and a water jacket which surrounds the elbow portion as well as the exhaust gas inlet portion and which communicates with a high rise tube which maintains the water jacket full of water around both the exhaust gas inlet portion and the elbow portion of the exhaust gas passageway.
- FIG. 1 is a fragmentary elevational view, partially in section, of one embodiment of an exhaust gas manifold in accordance with the invention.
- FIG. 2 is a fragmentary sectional view taken generally along line 2-2 of FIG. 1.
- FIG. 3 is a fragmentary sectional view taken generally along line 3-3 of FIG. 1.
- FIG. 4 is an end view taken generally along line 4-4 of FIG. 1.
- FIG. 5 is an elevational view, partially in section, of another embodiment of an exhaust gas manifold in accordance with the invention.
- FIG. 1 Shown in FIG. 1 is an exhaust gas manifold 11 which is mounted on an engine 13 including a plurality of exhaust ports 15.
- the exhaust gas manifold 11 includes an exhaust gas passageway l7v communicating with the engine exhaust ports 15 and with an outlet or discharge pipe 19 adapted to discharge the exhaust gas through the atmosphere, either above or below the waterline.
- the exhaust gas passageway 17 includes a first or inlet portion 21 which, in the illustrated construction, extends generally horizontally and communicates with the engine exhaust ports 15. Communicating with, and extending from, one end of the inlet portion 21 of the passageway 17 is a second or elbow portion 23 which bends downwardly to afford smooth flow of exhaust gas from the inlet portion 2 l. Communicating with, and extending from, the lower end of the elbow portion 23 is a third or discharge portion 25 of the exhaust gas passageway 17. While in the construction illustrated in FIG. 1, the above-mentioned exhaust gas portions 21, 23 and 25 are all formed in a unitary casting, the mani fold 11 could be manufactured of several pieces and suitably assembled.
- a main or first coolant or water jacket 31 which, at least partially, circumferentially surrounds the inlet portion 21 of the exhaust gas passageway 17 and which also, at least partially, circumferentially surrounds the elbow portion 23 and extends to the lower end thereof.
- the water jacket 31 extends around the sides of the exhaust gas passageway 17 which are not adjacent to the engine block.
- Communicating with the water jacket 31 is a coolant inlet or water entry port 33, a drain port 35 which is normally closed by a plug 36 except when draining the water'jacket 31 as, for instance, for winter storage, and a third or outlet port 37 in the form of a nipple.
- a second water jacket 41 which, at least partially, circumferem tially extends around the discharge portion 25 of the exhaust gas passageway 17 and which, at its lower end, communicates through peripheral slots 44 in an annular flange 46 with the outlet pipe 19 for drainage thereinto of the coolant and for mixture of the coolant with the exhaust gas. Except as hereinafter disclosed, the water jacket 41 does not communicate with the water jacket 31. Also provided in the second coolant or water jacket 41 is a port 43 in the form of a nipple.
- means for discharging coolant from the first water jacket 31 including means for maintaining the first water jacket 31 with coolant.
- such means communicates between the ports 37 and 43 and includes a high rise tube 47 for providing flow between the first or main water jacket 31 and the second coolant or water jacket 41, while simultaneously preventing drainage from the main water jacket 31 in the absence of an inflow of coolant through the entry or inlet port 33.
- the main water jacket 31 is maintained full of water at all times.
- the high rise tube 47 extends above the uppermost or top part of the main water jacket 31, but does not extend in cooling relation to the exhaust gas passageway 17. Because of the height of the high rise tube 47 above the uppermost part of the main water jacket 31, drainage of the main water jacket 31 in the absence of inflow of water is prevented and thus the main water jacket 31 surrounding both the inlet and the elbow portion 23 and 23, respectively, of the exhaust gas passageway 17 is maintained full of coolant at all times.
- the high rise rube' 47 comprises a rubber hose. Suitable clamps (not shown) can be employed to prevent leakage between thetube '47 and the ports or nipples 37 and 43.
- FIG. 5 Shown in FIG. is another embodiment of an exhaust gas r n anifold 111 communicating with a high rise tube 147. More specifically, the exhaust gas manifold 111 shown in FIG. 5 includes an exhaust gas passageway 117 having a first or inlet portion 121 which usually extends horizontally and which includes means adapted to be connected to the exhaust ports 115 of a multi-cylinder engine 123. The exhaust gas passageway 117 further includes an elbow portion 123 which extends downwardly from one end of the inlet portion 121 to afford smooth outflow of the exhaust gases, and a discharge portion 125 which extends downwardly from the elbow portion 123.
- the exhaust gas manifold 111 shown in FIG. 2 also includes a water jacket 131 which surrounds the inlet portion 121 and the elbow portion 123 of the exhaust gas passageway 117 and which also surrounds an upper part of the discharge portion 125 of the exhaust gas passageway 117.
- a suitable coolant or water inlet or port 133 is also provided.
- Means are also provided for discharging coolant from the jacket 131 and including means for maintaining the jacket 131 full of coolant at all times.
- Such means includes a port 137 connected with the water jacket 131 and the high rise tube 147 which communicates with the port 137, which extends to above the top of the water jacket 131, and which communicates with a port 143 extending from the dis charge portion 125 of the exhaust gas passageway 11 7 below the water jacketed part thereof.
- the high rise tube 147 includ3s a barrier or separator 149 which includes an upper or top edge 151 located above the top of the water jacket 131 and which extends in the high rise tube 147 so as to provide adjacent but separate passage portions 153 and 155, with the portion 153 extending upwardly from the port 137 to the top edge 1510f the separator or barrier 149, and with the portion 155 extending downwardly from the edge 151 of the barrier or separator 149 to the port 143 communicating with the discharge portion of the exhaust gas passageway 117.
- the water jacket 131 surrounding the horizontally extending inlet portion 121 and the elbow portion 123 of the exhaust gas passageway 117 is maintained full of water at all times.
- exhaust gas flow from the inlet portion 121 through the elbow portion 123 to the discharge portion 125 or outlet pipe 119 is unhindered, i.e., is not subject to unnecessary back pressure due to flow restrictions in the exhaust gas passageway 117.
- An exhaust gas manifold comprising an exhaust gas passageway including an exhaust gas inlet portion, and an elbow portion extending directly downwardly from said inlet portion, a coolant jacket extending around said inlet and elbow portions of said exhaust gas passageway, and valveless means for discharging coolant from said jacket and including means extending above the top of said coolant jacket in non-heat exchanging relation to said exhaust gas passageway for maintaining said jacket full of coolant.
- An exhaust gas manifold comprising an exhaust gas passageway including an inlet portion adapted to extend generally horizontally and adapted for communication with the exhaust port of an engine, an elbow portion extending directly downwardly from said inlet portion, and a discharge portion extending downwardly from said elbow portion, a first coolant jacket extending around said inlet and elbow portions of said exhaust gas passageway and including therein a port, a second coolant jacket extending around said discharge portion of said exhaust gas passageway and including therein a port, and valveless means for discharging coolant from said first jacket to said second jacket and including a coolant passage communicating between said ports and including means extending above the top of said first coolant jacket in non-heat exchanging relation to said exhaust gas passageway for maintaining said first coolant jacket full of coolant.
