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

In the case of a charge-air cooling circuit for a multicylinder internal-combustion engine 1 with a turbo-supercharger 2, it is proposed that downstream from the turbo-supercharger 2 the charge air be fed to two separate charge-air coolers 6, 6′, whereby the first charge-air cooler 6 divides the charge air into two flow branches I, II, effectively cools the first of the two flow branches I, and allows the second of the two flow branches II to pass essentially uncooled, and whereby the second charge-air cooler 6′ allows the first of the two flow-branches I to pass essentially uncooled, effectively cools the second of the two flow branches II, and then recombines the two flow branches I, II. According to the proposal, it is ensured that this charge-air cooling circuit is adapted to the special spatial conditions that exist inside the engine compartment of a multi-cylinder internal-combustion engine, especially an internal-combustion engine of the V-design, and provides for improved cooling performance compared to the state of the art.
