摘要： An exhaust heat recovery apparatus includes a reciprocating internal combustion engine in which a piston reciprocates in a cylinder to generate motive power; and a Stirling engine that recovers the thermal energy of the exhaust gas discharged from the internal combustion engine and converts the thermal energy into kinetic energy. The Stirling engine is united with the internal combustion engine. A heater that the Stirling engine includes is disposed in an exhaust manifold of the internal combustion engine.

摘要： In a Stirling engine, a casing houses therein component elements of the Stirling engine, including a high-temperature-side cylinder, a high-temperature-side piston, a connecting rod, a crankshaft, etc. A pressure control device determines whether the pressure of the gas charged in the casing has declined. If the pressure of the gas has declined, the pressure control device drives a pump to pressurize the gas charged in the casing.

摘要： A Stirling engine is provided with a fluid passage that connects a low temperature-side actuating fluid space and a crankcase inner space, and a passage opening/closing valve that is provided in the fluid passage and that opens and closes the fluid passage. Upon stopping of the Stirling engine, the passage opening/closing valve enables communication through the fluid passage, at a region at which the piston floats in the cylinder. This region is determined based on the pressure of an actuating fluid in the actuating fluid space and the rotational speed of a crankshaft of the Stirling engine.

摘要： An exhaust heat recovery apparatus includes: an exhaust heat recovery unit that produces motive power by recovering thermal energy from exhaust heat, wherein the produced motive power is combined with motive power produced by a heat engine and is output together therewith; an auxiliary that is driven by at least the exhaust heat recovery unit; and a power transmission-switching device that is provided between the heat engine and the exhaust heat recovery unit, the same power transmission-switching device being provided between the heat engine and the auxiliary, and that cuts off the connection between the heat engine and the exhaust heat recovery unit when there is no request to drive the heat engine. Thus, it becomes possible to effectively use the surplus motive power produced by the exhaust heat recovery unit when there is no request to drive the heat engine.
