Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to FIGS. 1 to 3: the utility model provides a diesel outboard engine control by temperature change and breather, includes shell 3, be equipped with centrifugal fan 4 in the shell 3, centrifugal fan 4 is connected with the flywheel 2 of engine 1, is equipped with a plurality of centrifugal blades 6 on the centrifugal fan 4.
In this embodiment, four support legs 7 are provided below the casing 3, and the casing 3 is bolted to the engine 1 via the support legs 7. A centrifugal fan 4 is arranged inside the housing 3, the centrifugal fan 4 is connected with the flywheel 2 of the engine 1 through bolts, and the centrifugal fan 4 is driven to rotate by the flywheel 2 when the flywheel 2 works. The periphery of the centrifugal fan 4 is provided with a plurality of centrifugal blades 6, the centrifugal blades 6 are distributed on the centrifugal fan 4 in the circumferential direction, and the centrifugal fan 4 rotates to drive the centrifugal blades 6 to rotate, so that waste gas and hot air generated by the engine 1 in the case shell are pumped away by the centrifugal fan 4 and are discharged from the outlet 5 of the case shell 3, and the purposes of discharging the waste gas and controlling the temperature are achieved. Because waste gas and hot-air in the case shell are discharged, negative pressure can be generated in the case shell, fresh air is absorbed from the outside and enters the case shell, and the effects of temperature control and air exchange are achieved.
The engine work can produce waste gas to and can improve the inside temperature of quick-witted case shell and cause the air in the quick-witted case shell to become the hot-air, and then the work that the engine can be influenced in the increase of hot-air and waste gas, make the loss increase of engine, generally can cause engine power loss about 10%.
In this embodiment, the centrifugal blade 6 is of an arc structure and is installed on the centrifugal fan 4 in a state of being perpendicular to the housing 3, that is, as seen from fig. 1, the centrifugal blade 6 is vertically arranged at an interval from the centrifugal fan 4, and the radians of the centrifugal blade 6 are all arranged towards one side; the arc-shaped structure is beneficial to intensively adsorbing the exhaust gas generated by the engine 1 together and then discharging the exhaust gas from the outlet 5 of the shell 3.
In this embodiment, the outlet 5 of the housing 3 is disposed on the side wall of the housing 3, and the outlet 5 extends to the outside of the housing 3 by a section, so that the housing 3 becomes a shell similar to a snail; the outlet 5 is provided with an air outlet 51, and the air outlet 51 is arranged on the side far away from the engine 1.
In this embodiment, the housing 3 is hollow in the middle, and the gas passage inside the housing 3 is a circular passage leading to the outlet 5. The centrifugal fan 4 is a disc with a hollow middle part, a bolt hole is arranged in the middle of the disc and is connected with the flywheel 2 through a bolt, and a plurality of centrifugal blades 6 with arc structures are welded at the edge of the disc.
The utility model discloses a use method: connecting a centrifugal blade 6 with a centrifugal fan 4, installing the centrifugal fan 4 on a flywheel 2 of the engine 1 through a bolt, sleeving a shell 3 above the centrifugal fan 4, and arranging four support legs 7 in bolted connection with the engine 1 below the shell 3; the engine 1 is started, the centrifugal fan 4 and the centrifugal blades 6 are driven to rotate under the action of the flywheel 2, and exhaust gas generated by the engine 1 is discharged from the outlet 5. Because waste gas and hot-air in the case shell are discharged, negative pressure can be generated in the case shell, fresh air is absorbed from the outside and enters the case shell, and the effects of temperature control and air exchange are achieved.
The present invention is not limited to the above embodiments, and various combinations and modifications of the above technical features may be provided for those skilled in the art, and modifications, variations, equivalents, or uses of the structure or method of the present invention in other fields without departing from the spirit and scope of the present invention are included in the protection scope of the present invention.
