SQCS Glow Plug OEM 0011592001 For Mercedes Benz W140 K

(1) the cylinder head is affected by high temperature and high pressure gas, and bears a large bolt pre-tightening force, resulting in large mechanical stress.
(2) The structure of the cylinder head is complex, and the temperature field is seriously uneven, leading to large thermal stress, which will cause cracks and overall deformation of the cylinder head. Therefore, the design requirements of the cylinder head are
(1) sufficient stiffness and strength, small working deformation, and ensure the sealing.
(2) Reasonable arrangement of combustion chamber, valve and airway to ensure the working performance of the engine. (3) Good manufacturability, uniform temperature field as far as possible, reduce thermal stress, avoid hot cracking phenomenon.
