An exhaust-driven cooling system for an internal combustion engine includes a turbocooler having an exhaust-driven turbine and ducted fan means to generate a flow of cooling air for use in an internal combustion engine heat exchanger to dissipate heat losses of the engine and a control for the generation of cooling air. The system can provide internal combustion engines with substantially reduced temperatures and pressures for its exhaust gas, thrust usable as a motive force and exhaust system components and substantially improved reliability and efficiency.
