Zhejiang ruiqing auto parts co., LTD. : how to deal with cylinder head cracking (1)

2019-02-19

  In winter when the temperature is low, the cylinder cover of diesel engine is prone to crack and water leakage. The main reasons are as follows:
  1. Add cooling water after starting. When the diesel engine is started, the temperature in the engine will rise immediately. If the cooling water is added, the cylinder body and cylinder cover will be cooled sharply, and cracks will be caused by shrinkage.
  2. After the machine is stopped, there is no cooling water. The water inside the engine freezes into ice, the volume increases, and the cylinder body and cylinder cover expand and crack occur. This paper is organized by zhejiang ruiqing auto parts co. LTD
