Charge cooling circuit for a multi-cylinder internal combustion engine with a turbo-supercharger

In a charge-air cooling circuit for a multicylinder internal-combustion engine with a turbo-supercharger downstream from the turbo-supercharger the charge air fed to two separate charge-air coolers whereby the first charge-air cooler divides the charge air into two flow branches I, II, cools the first of the two flow branches I, and allows the second of the two flow branches II to pass uncooled, and whereby the second charge-air cooler ′ allows the first of the two flow-branches I to pass uncooled, cools the second of the two flow branches II, and then recombines the two flow branches I, II.
