Why does Chery insist on using cast iron engines?

[MelanieLee]

Chery insists on using cast iron engines because they are lightweight and reduce fuel consumption. The following are the relevant details about cast iron engines: 1. Advantages: The cylinder block of a cast iron engine has higher hardness, is less prone to deformation, and is resistant to high pressure, high temperature, and corrosion. It is also cheaper than aluminum alloy, requires lower manufacturing technology conditions, and has mature processes. In actual operation, cast iron engines can withstand high-temperature and high-pressure working environments. 2. Disadvantages: Compared to aluminum alloy engines, cast iron engine technology is indeed relatively outdated. Cast iron engines are heavier and harder to meet current lightweight requirements. They also dissipate heat slower than aluminum alloy materials and have poorer toughness.
