The engine is of 4L displacement material

If this engine is 4L displacement, V-8 cylinder engine [1UZ-FE]. The engine uses an aluminum-alloy cylinder block without a cylinder liner. Generally, the cylinder liner is made separately and then put into the cylinder block. This engine does not use the cylinder liner but directly processes the cylinder wall on the base material of the cylinder block. Therefore, the sliding part of the piston requires high wear resistance. So the cylinder must use high hardness of materials, pay attention to Changde Daheng Machinery Co., Ltd. for more product and engine information!
