First Claim
Patent Images
1. A supercharging system for an internal combustion engine having two cylinder banks, comprising:
- at least two charge air coolers;
a first exhaust gas turbocharger representing a first stage of the supercharging system;
a second exhaust gas turbocharger representing a second stage of the supercharging system; and
a first nonreturn valve;
wherein;
each of the first and second exhaust gas turbochargers is situated next to one of the cylinder banks of the internal combustion engine;
the charge air coolers are situated in a parallel circuit, and partial flows of fresh air passing through them are combined at a junction connected upstream from a throttle device; and
the first nonreturn valve is situated upstream from the junction in a branch downstream from a first of the charge air coolers.
