摘要： A gas lubrication structure is provided with a high-temperature-side cylinder, an expansion piston lubricated relative to the high-temperature-side cylinder by gas, and a layer provided to the outer peripheral surface of the expansion piston and composed of a material flexible and having a higher linear expansion coefficient than the base material of the expansion piston. The thickness of the layer under normal temperatures is not less than the size of the clearance formed between the layer and the high-temperature-side cylinder. Also, even if the layer is thermally expanded under use conditions, the layer under normal temperatures has a thickness enabling a clearance to be formed between the layer and the high-temperature-side cylinder.

摘要： Provided is a control apparatus for an internal combustion engine which can favorably achieve a good balance between the prevention of an excessive increase in the piston temperature and the prevention of deterioration of various performances of the internal combustion engine as a result of execution of abnormal combustion suppression control, even when abnormal combustion occurs continuously or substantially continuously over a plurality of cycles. An in-cylinder pressure sensor (34) is provided to obtain the in-cylinder pressure P of an internal combustion engine (10). When continuous pre-ignition is detected using the in-cylinder pressure sensor (34), the control apparatus makes it more difficult for continuous pre-ignition suppression control to be executed when the Pmax at the time of pre-ignition is low than when the Pmax at the time of pre-ignition is high.

摘要： A Stirling engine has 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. The passage opening/closing valve enables communication through the fluid passage upon startup of the Stirling engine, and shuts off communication through the fluid passage when the rotational speed of the crankshaft of the Stirling engine is equal to or greater than a pre-established start-enabling rotational speed.

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 a Stirling engine and a clutch. The Stirling engine produces motive power by recovering thermal energy from exhaust gas discharged from an internal combustion engine from which exhaust heat is recovered. The motive power produced by the Stirling engine is transmitted to an internal combustion engine transmission through the clutch and an exhaust heat recovery device transmission, and combined with the motive power produced by the internal combustion engine through the internal combustion engine transmission, and is output from an output shaft. If rapid acceleration is required, and the increase in the rotation speed of the Stirling engine therefore lags behind the increase in the rotation speed of the internal combustion engine, the clutch is released. With this configuration, reduction in the power output from the heat engine, from which exhaust heat is recovered, is restricted, and the degradation of the acceleration performance is minimized.

摘要： A stirling engine includes a flow path which communicates a working space of the stirling engine and a crankcase of the stirling engine. An output of the stirling engine is controlled so that the output lowers when a pressure inside the working space is higher than a pressure in the crankcase, with a transfer of a fluid in the working space to the crankcase via the flow path thereby causing a decrease in the pressure of the working space.
