Engine exhaust heat recovering apparatus

An engine exhaust heat recovering apparatus for providing a heat output through a heat transfer medium circulated by the action of a water pump across a cooling section of the engine and an exhaust heat exchanger which heat source is provided with the heat generated in the exhaust gas of the engine, comprising:

• an oil heat exchanger for heat exchange between the engine oil in the engine and the heat transfer medium;
• and
• a heat transfer medium circulating path for conveying the heat transfer medium to the exhaust heat exchanger where the heat transfer medium receives heat from the exhaust gas so that a temperature of the water vapor in the exhaust gas is declined to a temperature lower than the dew point, passing the heat transfer medium through the oil heat exchanger, and transferring the heat transfer medium to the cooling section of the engine where the heat transfer medium receives heat from an engine cooling medium.
