工作中发动机缸体要承受混合气爆发力及气体压缩做功时的压力和高温、功率输出时曲轴的力矩以及发动机高速运转时的强烈震动等。气缸体负担很重,且工作条件恶劣,如果在日常使用中不注意维护保养,就会产生一些故障,引起早期损坏。研究气缸体破损的原因及其检修预防方法,对确保发动机工作正常有着重要意义。 Working cylinder block to withstand the explosive gas mixture and gas compression work done when the pressure and high temperature, power output when the crankshaft torque and high speed engine when the strong vibration. Heavy cylinder load, and poor working conditions, if not pay attention to maintenance in daily use, there will be some failure, causing early damage. Study of the reasons for the damage of the cylinder block and the method of overhaul and preventive measures are of great significance to ensure the normal operation of the engine.
