New description: [New technical field] This creation is about the structure of a car engraving hood, especially the structure that can increase the air volume of the air hood.曰[Prior Art] According to the general forced air-cooled engine, as shown in Figure 1 and Figure 2, it is mainly composed of the engine power system 1 and the cooling air hood 2 through the engine power button 1. The cooling air hood 2 series will be engine power! The outer cooling air is forced by the fan 11 of the engine 1 and enters the air hood 2 through the air vent 2 of the fan cover 23, and the cooling air is blown by the guide hood 2 The engine 1 is used to take the high temperature of the engine 1 through the heat exchange and the fresh balance, and the air outlet 2 2 of the air duct 2 is arranged to cool the engine 1 to cool down. In addition, the conventional air hood 2 guides the population of the outside cold air, p, has the air inlet 21 located on the fan cover 23, so the amount of air entering the air hood 2 from the outside cold air is greatly affected. The limitation of the cooling air in the air hood 2 is insufficient to further reduce the cooling efficiency of the engine 1. The conventional air hood 2 is only introduced into the outside air by the air inlet 21 located on the fan cover 23, and there is a shortage of external cold air, which may cause a poor cooling of the engine 1, which occurs. If the temperature is badly bad, some parts of the engine will be deformed, which will shorten the service life of the engine 1. Therefore, the conventional air hood 2 is necessary for improvement. In view of the fact that the conventional vehicle engine air hood structure has the above-mentioned lack of M353995 in use, there is still Yang perfection, _ experience, for the conventional engine cooling mechanism - research = eve of the relevant industry and correction , finally got the _. %良's clothing test [New content] Guide wind vehicle _ windshield structure, the r-

Can increase the number of miscellaneous fruits such as [Embodiment] In order to make the stomach examiner more aware of the structure of the creation and the achievable effect, the following diagrams are followed: • , H, please refer to _3 The bow of the created vehicle engine air hood structure | Engine 3 includes a crankshaft 3, a crankshaft 3 connected to the crankcase 3, a cylinder body 3 on the curved tree 31, and a cylinder The piston 2 in the body 3 3, the cylinder head 35 disposed on the cylinder body 3 3, and the fan 36 driven by the crank shaft 3 27 . In addition, the cylinder body 3 3 and the steam & head 3 5 are arranged to provide a plurality of spaced-arranged heat radiating fins 3 31 and 3 51 on the steam body 3 3 and the cylinder head 35; After the human combustion chamber 3 8 , through the Mars M353995 • plug 3 7 points more explosive, its expanding gas _ force will produce the thrust shaft piston 3 4 for the upper and lower reciprocating motion, when the piston 34 4, the intake valve · (4) The gas is filled into the combustion chamber 38, and the exhaust gas is quickly exhausted by the exhaust gas and discharged to the exhaust pipe (not shown) through the exhaust gas. When the engine 3 is in operation, the crankshaft 32 will drive the fan 36 to operate, and the external cooling air is taken into the windshield 4 by the cooling wind gust 411 of the fan cover 41, and passes through the air hood 4. The cooling air passage between the body 3 3 and the steam red head 35 causes the cooling air to heat the heat sink 3 3 i, 3 5 on the steam body 3 3 and the cylinder head 35 (ie, the inter-heated air Taking away 'to achieve the purpose of cooling the vapor red body 3 3 and the cylinder head 35' allows the engine 3 to operate at normal operating temperatures. Please refer to the fourth and fifth times. 'The air hood 4 is covered by the cylinder body 3 3 of the 3 and the cylinder head 35. The hood 4 includes a fan cover 4 1 and an upper cover. 42. The cover 43 and the drainage member 44; the fan cover 4 1 is disposed behind the upper cover 4 2 and the lower cover 4 3 , and the air inlet 41 1 is opened on the side of the side, and the air inlet 41 is provided. i can supply cold air into the air hood 4; • the upper cover 4 2 is above the lower cover 4 3, and an access hole 42 1 ' is provided at the upper end. The trachea (five) is not shown); the lower cover 43 is disposed below the upper cover 42, and the lower cover 43 is respectively opened and has a cold air outlet 4 The exhaust pipe (not shown in the drawing) is provided with an exhaust perforation 4 3 2, an intake D 4 3 3 and a fixing hole 4 3 4, and the intake 5 M353995 port 4 3 3 is located with the fan cover 4: The same side of the tuyere, the fixing hole 4 3 4 can be fixed by the drainage member 44; the drainage member 44 has at least a drainage opening 441, an upper guiding portion 44, a side guiding portion 443 and The fixing portion 444 is connected to the inlet σ4 3 of the lower cover 盍 4 3 Correspondingly, the fixing portion 44 4 is a locking column, which can be a subsidy for the rigid strength of the drainage member 44. In the implementation of the present invention, please refer to Figures 6 and 7. The component s is passed through the fixing hole 4 3 4 of the lower cover 43 and the mosquito part 4 4 4 ' of the drainage member 44 to fix the drainage member 44 to the lower cover 43 and to guide the drainage member 44 The port 4 41 corresponds to the air inlet 4 3 3 of the lower cover 4 3; thereby, the guide portion 4 4 , the side guide portion 4 4 3 and the drain port 4 can be guided by the member 4 4 41 to form a first-class road a. - The person sees Figures 2, 6 and 7. When the crank shaft 3 2 drives the fan 36 to operate, the outside cooling air will enter the air hood * from the cooling air inlet 411, ..., However, due to the operation of the fan 36, the drainage member 44 at the front of the fan 36 can be made into a collapsed shape. Therefore, part of the external cold space can be passed through the air inlet 4 of the lower cover*3. 3 In the air intake hood 4, the air inlet 4 3 3 of the lower cover 4 3 and the cold air of the hood 4 can be sucked into the fan 3 6 through the flow path of the flow guiding member 44. And the fan 3 6 is inhaled from the air inlet 411 Together with the outside cold air, the cooling air can be directed to the cylinder head 35 of the engine 3, the spark star illusion and the cylinder by the guiding portion of the deflecting member 44 and the side deflecting portion 4 4 3 of the drainage member 44. The heat sink 3 3 of the body 3 3 is cooled by the work, and the cooled hot air is discharged from the air outlet 4 3 i of the M353995 "4 3", thereby effectively lowering the temperature around the engine 3. 1A, the air inlet 4 3 3 is opened in the lower cover 3 4 3 and the drainage member 4 4 is provided, so that the air hood 4 can be cooled by the air inlet 4 of the fan cover 4 In addition to the human air hood 4, the lower cover 4 3 air inlet 4 3 3 can be added, and the industrial air enters the air hood 4, thereby effectively increasing the outside cold air into the air hood 4 The air volume of the person is to improve the overall heat dissipation effect of the engine 3, thereby improving the use efficiency of the engine 3. According to the comprehensive j, the structure of the rudder guide hood of the present invention is melted under the air hood 4, and the cover 4 3 is opened - the air inlet 4 3 3 is provided and the drainage member 44 is arranged, thereby increasing the outside cold The air enters the air duct of the windshield 4, but can improve the conventional knowledge: lack, has improved the efficiency compared with the practice, has already had the application for turning the patent of 7 materials, please ask the review committee to listen to the audit, the second J review To the sense of virtue.
