Abstract
An intake valve for an engine supplies an intake gas to a combustion chamber of the engine, and an adiabatic coating layer including a polyamideimide resin and an aerogel dispersed in the polyamideimide resin and having thermal conductivity of 0.60 W/m or less may be formed on a surface portion that comes into contact with a flame during operation of the engine.
Claims21
An intake valve for an engine, which supplies an intake gas to a combustion chamber of the engine, comprising:
- an adiabatic coating layer including a polyamideimide resin and an aerogel dispersed in the polyamideimide resin and having thermal conductivity of 0.60 W/m or less is formed on a surface portion of the intake valve configured to come into contact with a flame.
An intake valve for an engine, which supplies an intake gas to a combustion chamber of the engine, comprising:
- an adiabatic coating layer including a polyamideimide resin and an aerogel dispersed in the polyamideimide resin and having thermal conductivity of 0.60 W/m or less is formed on a neck portion of the intake valve configured to come into contact with the intake gas.
