摘要

A cylinder head for an engine is disclosed. The disclosed cylinder head for an engine has an insulation coating layer having heat conductivity less than 0.60 W/m, and comprises: a polyamide-imide resin formed on a surface of an intake port; and an aerogel dispersed on the polyamide-imide resin. The present invention uses the insulation coating layer on the surface of the intake port in order to restrict a temperature rise of intake air.
