Why does Audi use cast iron cylinder blocks?

[LaAmara]

Because cast iron cylinder blocks have stronger thermal load capacity, more mature technology, greater cylinder block strength, higher durability and reliability, larger adjustable limits, and greater potential. Cast iron engines exhibit excellent heat resistance, demonstrating far superior stability compared to aluminum engines during high-temperature, high-speed driving. Below are relevant introductions about cylinders: Introduction to Cylinders: In pneumatic transmission, cylinders are pneumatic actuators that convert the pressure energy of compressed gas into mechanical energy. There are two types of cylinders: those performing reciprocating linear motion and those performing reciprocating swinging motion. Cylinders performing reciprocating linear motion can be further divided into four types: single-acting, double-acting, diaphragm-type, and impact cylinders. Function of Cylinders: To convert the pressure energy of compressed air into mechanical energy, driving mechanisms to perform linear reciprocating motion, swinging motion, and rotational motion.
