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： During starting of an engine that has a circulation path through which argon, used as working gas, is circulated back to a combustion chamber and that uses hydrogen as fuel during operation, oxygen is supplied in such a manner that the oxygen supply ratio is higher than that used during normal operation. Thus, the entirety of hydrogen supplied into the combustion chamber reacts with oxygen and is burned. When the engine is being started, because gas is not turbulent enough, hydrogen and oxygen are likely to be mixed poorly. Therefore, when oxygen is supplied in such a manner that the ratio of oxygen supply amount to the hydrogen supply amount is higher than the theoretical ratio, even if oxygen and hydrogen are not mixed so well, the chance that hydrogen contacts oxygen is increased. As a result, combustion takes place in a more appropriate manner, which improves the engine startability.
摘要翻译：在具有循环路径的发动机启动期间，用作工作气体的氩循环回到燃烧室，并且在运行期间使用氢气作为燃料，以这样的方式供给氧气，使得供氧比高于正常运行时使用。因此，供入燃烧室的氢气全部与氧气反应并被燃烧。当发动机启动时，由于气体不够湍流，氢气和氧气很可能混合不好。因此，当氧供给量与氢供给量的比率高于理论比时，即使氧气和氢气不良混合，也能够提高氢接触氧的可能性。结果，以更适当的方式进行燃烧，这提高了发动机起动性。

摘要： An internal combustion engine comprises a variable compression ratio mechanism capable of varying the mechanical compression ratio and a variable valve timing mechanism capable of controlling the closing timing of an intake valve. In an engine low-load operation, the mechanical compression ratio is maintained at a maximum mechanical compression ratio. In an engine high-load operation, the mechanical compression ratio is gradually decreased as the engine load increases. In the engine high-load operation, a load at which a predetermined mechanical compression ratio lower than the maximum mechanical compression ratio is obtained is preset, and a throttle valve is closed in the range of loads lower than the preset load.

摘要： In an engine 10, oxygen, hydrogen serving as fuel, and argon gas serving as a working gas are supplied to a combustion chamber 21. An upstream condenser section 70 condenses water vapor contained in an exhaust gas to yield primary condensed water, through heat exchange of the exhaust gas from the combustion chamber with the ambient air, and discharges, as a primary-condensed-water-separated gas, a gas obtained by separating the primary condensed water from the exhaust gas. The primary condensed water is stored in a water storage tank 100. A downstream condenser section 80 further condenses water vapor contained in the primary-condensed-water-separated gas to yield secondary condensed water, through utilization of latent heat of vaporization of condensed water stored in the storage tank 100, and discharges a gas obtained by separating the secondary condensed water from the primary-condensed-water-separated gas. This avoids a significant drop in ratio of specific heats of the working gas.
