1、水箱中为什么冒气泡柴油机水箱中冒气泡,一般是气缸中的高压气体窜入冷却水道造成的。其原因有六:①未按规定拧紧缸盖螺母,致高压燃气窜入水道;②气缸垫使用时间过长,密封性差,造成漏气;③气缸垫被冲坏或烧损,造成窜气;④缸盖平面加工不平或变形,造成漏气;⑤装配不当,造成缸 1, why the bubble in the water tank to bubble bubbles in the water tank, usually high-pressure gas cylinder into the cooling water channel caused. The reason there are six: ① not tighten the cylinder head nuts, resulting in high-pressure gas channeling into the waterway; ② cylinder pad used for too long, poor sealing, resulting in leakage; ③ cylinder pad was washed or burned, resulting in channeling gas; ④ flat surface machining uneven or deformation, resulting in leakage; ⑤ improper assembly, resulting in cylinder
