Description

一种汽油机
本实用新型涉及一种汽油机。
现有技术的汽油机,一是其缸体的扫气道一般为闭式,这种闭式结构扫气道的缸体,压铸制造效率低,废品率高,难以适应大批量生产的需要;二是它的散热片形状通常为园形,其散热面积小,散热性能差,易影响汽油机的工作效能;三是缸体与曲轴箱的连接一般都是采用四根长螺栓从缸体顶部穿入连接固定在曲轴箱上,这种连接固定方式,易导致缸体变形,使用可靠性差。
本实用新型的目的是为克服现有技术汽油机所存在的上述缺陷,而提供一种改进的汽油机。
本实用新型的目的是在现在技术的基础上改进实现的,它包括缸体、曲轴箱等。其要点在于缸体的扫气道为开式,缸体散热片形状为方形,缸体下部法买盘四角设孔,用螺栓直接与曲轴箱相连接。
下面结合附图对本实用新型进行详细说明:
图1是本实用新型的主视图
图2是本实用新型的侧视图
图3是本实用新中缸体部分主视图
图4是缸体部分侧视图
图5是缸体部分仰视图
根据图1-5所示,图中3是缸体,其扫气道成开式,散热片5的形状为方形,缸体3底部法兰盘4的四角设有螺栓孔7,通过螺栓2直接与曲轴箱1相连接。
本实用新型汽油机,其缸体扫气道采用开式,便于铸造,生产效率高,废品率低,利于大规模化生产。它的散热片采用方形,散热面积大,有利于提高汽油机的工作性能,其缸体与曲轴箱连接固定,是采用螺栓将缸体底部的法兰盘直接与曲轴箱连接,有利于避免缸体变形,可靠性好。
