冬季气温低,柴油机汽缸盖易发生裂缝漏水,其主要原因有以下几个方面:1 起动后才加冷却水 柴油机起动后,机内温度立即升高,如果这时加入冷却水,汽缸体与汽缸盖急剧冷却,就会因冷缩而裂缝。2 停机后,没有放冷却水,机内水冻结成冰,体积增大,发生汽缸体和汽缸盖胀裂。3 柴油机长时问运转,机内温度高,停车后立即放掉高温水,会导致高温零件骤遇冷空气而开裂。
Low temperature in winter, diesel engine cylinder head prone to crack leakage, mainly for the following reasons: 1 after the start of cooling water after the diesel engine starts, the temperature inside the machine immediately increased, if the time adding cooling water, the cylinder block and the cylinder Cover rapid cooling, it will shrink due to cracks. 2 shut down, no cooling water, the machine frozen in water ice, the volume increases, the occurrence of cylinder block and cylinder head burst. 3 diesel engine long time to run, the machine temperature is high, immediately after the release of high temperature water, will lead to high temperature parts suddenly cold air and cracking.
