ABSTRACT OF THE DISCLOSURE An internal combustion engine intake valve with an internal heat pipe. The valve stem and valve head are hollow and have a wicking material fixed to the internal hollow surface. A coolant material is contained within the hollow valve. A heat exchanger is provided on the outer surface of the stem at the valve operator end. The portion of the valve in the fuel intake system is main- tained at a temperature that will prevent the addition of heat to the fuel charge from the valve thus reducing the possibility of autoignition due to heating of the fuel charge.
