An exhaust-driven cooling system for an internal combustion engine includes a turbocooler having an exhaust-driven turbine and 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. The system can provide internal combustion engines with substantially reduced temperatures and pressures for its exhaust gas and exhaust system components and substantially improved reliability and efficiency.

An oil-only, internal combustion engine system with an exhaust-driven, cooling system, comprising: a multi-cylinder, internal, combustion-engine assembly; means for providing a mixture of fuel and air to the internal combustion engine assembly; means for carrying the product of the combusted fuel-air mixture from the internal combustion engine assembly; means for providing a flow of lubricant to and from the internal combustion engine assembly for lubricating the internal combustion engine assembly and for carrying heat generated by operation of the internal combustion engine assembly away from the internal combustion engine assembly; an oil cooler, connected with said means for providing a flow of lubricant, to dissipate the heat carried by said lubricant from the internal combustion engine assembly prior to its return to the internal combustion engine assembly; a turbocooler having a turbine connected with the means to carry the product of the combusted fuel-air mixture from the internal combustion engine assembly so that the exhaust gas carried from the internal combustion engine assembly by said exhaust means drives the turbine of the turbocooler, said turbocooler also having a ducted fan means driven by the turbine of the turbocooler, said ducted fan means communicating with atmosphere and generating a ducted flow of cooling air; means for directing the flow of cooling air generated by the fan means of said turbocooler through the oil cooler to cool the lubricant and dissipate the heat generated in operation of the internal combustion engine assembly; and means for directing the cooling air generated by said turbocooler from said oil cooler to said means for carrying the product of the combusted fuel-air mixture from said internal combustion engine assembly, said means for directing the cooling air including a portion forming a cooling air inlet surrounding said means for carrying the combusted fuel-air product prior to its leaving the exhaust-carrying means, thereby substantially reducing both the temperature and the pressure of the internal combustion engine exhaust.
