（1）敲缸现象 机“敲缸”是指活塞敲击气缸时发出的一种有节奏的、清晰的“咣当”声，一般在机附近能听到。当机大负荷、转速突然变化或运转时，声音更明显。（2）敲缸原因1）活塞与气缸磨损严重，配合间隙过大，活塞在上、下运动中发生摆动，撞击缸壁，属机械“敲缸”。机械“敲缸”在机起动初期，即冷状态时响声明显，机温度升高后，响声减弱或消失。2）喷油时间过早或产生“爆燃”而引起燃气动力“敲缸”。“爆燃”是由于个别缸喷油器喷油压力过低，雾化不良或有严重的滴油，在燃烧过程的滞燃期积聚过多燃油而产生。燃气动力“敲缸”不随机温度改变而变化，当整机供油提前角太大时，还有振动和噪声加剧现象。动力设备（深圳）有限公司隶属于集团旗下果洛干式变压器组业务中国区服务提供商，主要运营东风和两大品牌在中国的果洛干式变压器组产品的出售租赁、维修保养及其售后服务。为军工企业、工厂矿业、商场超市、地产酒店、建筑施工、桥梁隧道、活动演出、娱乐会所演唱会供应紧急和长期后备应急电源，根据果洛干式变压器组其功能区分为：移动式、固定式、超静音式、机组载式发电设备。常见功率（千瓦）范围：50KW,,150KW,200KW,250KW,300KW,400KW,500KW,800KW,1000KW等功率段。更多有关的最新产品和技术内容，请登录果洛干式变压器官网首页：
