Abstract
An internal combustion engine having a supercharger and two or more supercharger intercoolers or cooling systems respectively having different temperature levels. The individual coolers are arranged in succession in the direction of flow, with the charged air decreasing in temperature and the cooling air increasing in temperature.
Claims10
An arrangement comprising in combination:
- an internal combustion engine;
- a supercharger for supplying charged air to said internal combustion engine;
- at least two means for cooling said charged air having different temperature levels and being interposed between said supercharger and said internal combustion engine as well as communicating with same and being located in the charged air flow path, said means for cooling charged air comprising an air cooled supercharger intercooler and at least two liquid cooled supercharger intercoolers each having a different temperature level as well as being arranged ahead of said air cooled supercharger intercooler in the direction of charged air flow, and an air cooled heat exchanger operatively connected to said liquid cooled intercoolers and located in the flow of said cooling air from siad air cooled supercharger intercooler;
- and means for drawing cooling air into said arrangement, said means for cooling charged air being arranged in succession in the stream of said charged air in such a way that the temperature of said charged air decreases in the direction of flow thereof, and the temperature of said cooling air increases in the direction of flow thereof.
