气缸盖和气缸体大多用灰铸铁或铝合金铸造而成。它的技术状态好坏,对发动机其他零件安装的相对位置和正常工作影响极大。现将气缸盖和气缸体常见的故障和排除方法简要介绍如下。 1.上平面翘曲及腐蚀 (1)故障原因。发动机温度过高与急冷;拧紧缸盖螺母用力不均;时效处理不充分;冷却水或窜漏的燃烧气体腐蚀气缸体不平面的水道口及气缸口周围。其结果,不仅会烧毁气缸垫,使发动机功率下
Cylinder head and cylinder block mostly made of gray cast iron or aluminum alloy. Its technical condition is good or bad, the relative position of the other parts of the engine installation and normal work great influence. Now the common cylinder head and cylinder block failure and troubleshooting methods are as follows. 1. On the plane warpage and corrosion (1) the cause of the malfunction. Engine temperature is too high and quench; tighten the cylinder nut uneven force; aging treatment is not sufficient; cooling water or blowby combustion gases corrode cylinder block uneven mouth and around the cylinder mouth. As a result, not only will the cylinder pads be burned so that the engine power is lower
