Structural improvement of piston wear-resistant insert rings for automotive engines
The structure evolution of wear-resistant insert ring of automotive engine piston is ana-lyzed.Combined with the requirements of piston performance at the present stage,through the methods of simulation design and on-site analysis,the innovative design improvement of the structure of wear-resistant insert ring is carried out.Results show that the innovative structure has advantages in light weight,casting quality and structure layout of the piston,which can reduce the probability of separation between the ring and the matrix in the machining process of the piston,improve the pouring flow of the liquid aluminum,and ensure the quality of the casting product.
