Introduction

I. What is an Engine Block?

The engine block (cylinder block) is the structural core of internal combustion engines, housing cylinders, pistons, and crankshafts to convert thermal energy into mechanical power. As a Top 10 Global Engine Block Manufacturer, we deliver IATF 16949 (automotive) and ISO 19902 (marine) compliant castings for automotive, shipbuilding, agriculture, and construction machinery industries.

II. Core Advantages

  1. High-Strength Engine Blocks

    Withstands 200°C+ temperatures and 10MPa combustion pressure (deformation <0.05mm).

  2. Lightweight Aluminum Engine Blocks

    160-200W/(m·K) thermal conductivity reduces engine weight by 25-35% (ideal for EVs/hybrids).

  3. Low-Noise Design

    Vibration-optimized structure cuts noise by 5-10 dB (SAE J1074 certified).

  4. Corrosion-Resistant Marine Engine Blocks

    Micro-arc oxidation coating passes 720+ hours salt spray tests (ISO 9227).
