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： 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.
