This engine cylinder block is precision-cast from high-strength alloy cast iron or aluminum alloy, featuring compact structure and excellent rigidity with outstanding heat dissipation and wear resistance. It provides a stable working environment for pistons, crankshafts and other parts, enhancing power output and overall reliability.
Machined to strict OEM standards, it has high-precision cylinder bores, well-designed water and oil passages, and excellent sealing performance for direct engine repair and assembly replacement.
Processed with aging treatment and fine honing, it resists deformation and cracking, suitable for high-load and long-hour operation. With high cleanliness, it is corrosion-resistant and wear-resistant to extend engine life.
Having passed air-tightness, strength and durability tests, it meets international engine manufacturing standards. Suitable for various passenger and commercial vehicles with bulk cross-border supply available, it is an ideal core component for the overseas engine repair aftermarket.
