Abstract

A mounting structure for induced air plates on an engine, comprising a cylinder sleeve (3), a first induced air plate (1) and a second induced air plate (2). The first induced air plate (1) and the second induced air plate (2) are mounted about a cylinder sleeve (3), forming a cooling air duct with the cylinder sleeve (3). The second induced air plate is provided with ventilation holes (2a). The mounting structure is simple, compact, sound and simplifies the structure of the engine. The mounting structure reduces the cost of producing the engine, and improves engine cooling performance. In addition, the mounting structure isolates noise originating from the cylinder sleeve when the engine is running, thereby reducing engine noise.

具体实施方式 detailed description

下面本发明将结合附图中的实施例作进一步描述：  The invention will be further described below in conjunction with the embodiments of the drawings:

如图 1〜图 3所示， 包括第一引凤板 1、 第二引凤板 2、 缸套 3、 飞轮 4、 导风罩 5、 机体 6及曲轴 7等。  As shown in Fig. 1 to Fig. 3, it includes a first phoenix plate 1, a second phoenix plate 2, a cylinder liner 3, a flywheel 4, an air hood 5, a body 6 and a crankshaft 7.

所述第一引凤板 1和第二引凤板 2安装在缸套 3周围， 且与缸套 3形成 冷却风道。所述第二引凤板 2上设置有通风孔 2a。 该种引风板的安装结构可 以使引凤板装置和机体 6分离， 使得发动机的机体 6变得结构很简单。  The first phoenix plate 1 and the second phoenix plate 2 are mounted around the cylinder liner 3 and form a cooling air passage with the cylinder liner 3. The second draft plate 2 is provided with a vent hole 2a. The installation structure of the air deflector can separate the phoenix device from the body 6, so that the body 6 of the engine becomes simple in structure.

如图 3所示， 当发动机起动后， 经由曲轴 7带动飞轮 4， 在导风罩 5的 作用下， 冷却风导向缸套 3， 第一引风板 1、 第二引风板 2可以和缸套 3形 成冷却风道，这样就可以很好的对发动机进行冷却，提高发动机的冷却性能， 同时也能隔离由发动机运转时从缸套发出的噪音， 降低发动机的噪音。 由于 在引风板 2上设置有通风孔 2a， 可以使得拐弯处的冷却风不形成死角， 从而 更好的提高发动机的冷却性能。 As shown in FIG. 3, after the engine is started, the flywheel 4 is driven via the crankshaft 7, and under the action of the air guiding hood 5, the cooling air is guided to the cylinder liner 3. The first air guiding plate 1, the second air guiding plate 2 and the cylinder Set of 3 It is a cooling air duct, which can cool the engine well, improve the cooling performance of the engine, and also isolate the noise emitted from the cylinder liner when the engine is running, reducing the noise of the engine. Since the air venting hole 2a is provided on the air guiding plate 2, the cooling air at the turning portion can be prevented from forming a dead angle, thereby further improving the cooling performance of the engine.
