Field of the Invention The present invention relates to a cooling structure of an engine, and more particularly to a cooling structure which can improve temperature unevenness on both sides of a cylinder body of an engine. [Prior Art] The engine 1 for a vehicle is shown in the first figure, wherein the belt change mechanism 2 is housed in a transmission filial 1 1N, and the power generated by the engine i is transmitted through the crankshaft 13 in the crankcase 2 The belt shifting mechanism 2 is driven. The belt shifting mechanism 2 includes: a sliding disc 2 disposed on the crankshaft 3, a driving disc 2 disposed on one side of the sliding disc 21, and disposed on the crankshaft 13 a ball 24 that is located between the sliding plate 21 and the swash plate 23, a driven disk that is driven by the rear wheel _2 5, and a passive disk 26 that is disposed on the esoteric 205, is fixed to the passive shaft A clutch 2 7 on a 25, a transmission belt 2 8 and a bearing cover 9 on the transmission case cover 111 of the transmission case 11 are used to support the bearing 2 9 of the driven shaft 25. Wherein, the movable disc 2 1 and the driving disc 2 2 form a leather (four) speed mechanism 2 'the end of the transmission belt 28 is located between the driving disc 2 2 and the sliding disc 21 'the other end is located Two passive disks between 2 and 6. Express the engine! In the combustion chamber 16, by the power generated by the explosion, the thrust of the base 1 4 to the axis 'in the (four) Lai Shun 3 crane, the system (4) dreams of the positive time of the room 1 7 timing chain 18 to drive the cam axis! 9 turns, the camshaft 1 9 in, the suspicion〗 (Figure to make the material can be continuously ignited and ignited, the other car can be rotated by 13 at the same time 乍 ^ 200806873, 21 and the drive plate 2 2, At this time, the ball 24 is moved by the centrifugal force. When the throttle is increased, the rotation speed of the crankshaft 13 is also increased, and the ball 24 is increased by the centrifugal force and moved outward. When the sliding plate 2 is pressed, the ball 24 abuts against the driving plate 22, and the distance between the driving plate 22 and the sliding plate 21 is reduced, which drives the transmission belt 28 to expand, thereby increasing The transmission belt 28 rotates to the circumferential range, thereby speeding up the passive disk 2 (four) speed, and driving the passive shaft 25 through the clutch 27 to drive the rear wheel (not shown) to increase the speed, thereby increasing the vehicle's The speed of travel. Conversely, when the throttle is released, the centrifugal force of the ball 24 is reduced, and the pressing of the drive belt 28 causes the distance between the drive plate 22 and the riding plate 2 to increase. The circumferential rotation range of the drive belt 28 will be reduced, so the passive disk 26 speed It will also be lowered, and the rear wheel will decrease the speed as the speed of the passive shaft 25 decreases, and the speed of the vehicle will be slowed down. The engine 1 mainly pushes the fuel in the combustion chamber 16 to push the piston 14 The reciprocating motion is performed in the cylinder body 1 to drive the crankshaft 13 to generate a power in a circular motion. Since the piston cymbal 4 performs a high-speed back and forth movement in the cylinder body i, the crankshaft 13 is disposed in the cylinder 瑕1〇. The camshaft 9 in the 1 is also quickly actuated 'so the other components of the engine 1 are driven at a high speed, in order to avoid the increase of the contact friction caused by the components of the engine 1 (including the piston, the crankshaft, the camshaft, etc.) Damaged. Therefore, the engine 1 has a lubrication system. As shown in Figure 1, the lubrication system is basically connected by the connected sump 3, the oil pump 31, and the 200806873 to the pipeline 32 gentleman _ continuous through the wheel The oil in the pumping tank 3 of the oil collecting machine 31, the plug 14 and the steam (four) χ = material 1 is suitable 'such as the cylinder body 1 0, after the live oil is recovered to the sump second wheel engine 1 'most

The damage is really a major issue for the locomotive industry. [Summary of the Invention] The main purpose of this month is to provide a cooling structure for the engine, mainly in the camshaft of the engine _ Sheershe channel, and to open the first field and the first wjif road on the domain road and borrow The outlet of the second sub-passage is disposed between the first sub-passage and the positive-wheel, and the lubricating oil is ejected from the outlet of the second sub-passage, that is, the steam-synchronized body of the second and second sub-channels is 200806873. As a result, the lack of a sentence in the second part of the Ke Qian Qian cylinder can improve the use of the engine. " [Implementation]
