A method of, and apparatus for, intercooling the charge air of a pressure-charged internal combustion engine by way of an air-cooled heat exchanger, the internal combustion engine being pressure-charged by a gas-dynamic pressure-wave machine. The entire quantity of outside air drawn in by the pressure-wave machine is divided into a partial stream of scavenging air and a partial stream of charge air. The scavenging air flows through the heat exchanger as a coolant and upon leaving the latter performs its intended scavenging function in the pressure-wave process, and the charge air, having been compressed in the pressure-wave process, is intercooled in the scavenging air-cooled heat exchanger.
