What is the gap between domestic car engines and foreign ones?
1 Answers
Domestic engines cannot match the material and process levels of imported engines. Here is a relevant introduction about the gap between domestic car engines and foreign ones: 1. Engine: The main differences lie in engine technology and manufacturing processes. Foreign technology is very advanced, such as the design of intake and exhaust ports. Many domestic engines are either designed with reference to foreign engines or directly commissioned from foreign design companies. Processing is also an important aspect. The reason why few domestic engine components can be used in foreign engines is largely due to the failure to meet required processing technology and craftsmanship standards. The fit between parts is not on the same level. 2. Material: Importing materials can only guarantee composition, but heat treatment processes still rely on domestic capabilities and are highly complex. Simply importing a furnace does not solve the problem—the key lies in the process flow! Among domestic metal suppliers, Baosteel is considered relatively good, but it still lags behind foreign standards, and the same applies to civilian products. As a result, domestic products often look appealing but lack durability. Engines are different from general mechanical products because they operate in high-temperature environments, which imposes even higher demands on materials.
