摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of improving startability.
SOLUTION: In the engine 1 including a circulation route 30 in which argon which is working medium is circulated between a combustion chamber 15 and the same, and using hydrogen for fuel during operation, oxygen is supplied during start of the engine 1 with supply rate increased as compared to oxygen supply rate during normal operation. All of hydrogen supplied to the combustion chamber 15, thereby, can be reacted with oxygen and burn. Namely, mixing of hydrogen and oxygen tends to be deteriorated since turbulence of gas is small during start. Consequently, probability of encounter of hydrogen and oxygen can be increased by supplying oxygen higher than theoretical rate to the supplied hydrogen even if mixing is somewhat bad. As a result, combustion during start can be improved and startability can be improved.

摘要翻译：解决的问题：提供能够提高起动性的内燃机。解决方案：在包括循环路径30的发动机1中，其中在工作介质中的氩在燃烧室15与其之间循环，并且在运行期间使用氢气作为燃料，在发动机1起动期间，供应量比正常运行时的供氧量提高。供应到燃烧室15的氢气全部可以与氧气反应并燃烧。即，由于起动时气体的湍流小，所以氢和氧的混合倾向于劣化。因此，即使混合有些差，也可以通过向所提供的氢提供比理论速率高的氧气来提高遇到氢气和氧气的可能性。结果，能够提高起动时的燃烧，提高起动性。版权所有（C）2010，JPO＆INPIT

摘要： PURPOSE: To enable it to control the timing of ignition even in case of such fuel as being low in a self-ignition temperature by premixing fuel in intake air uncontained oxygen at an inlet stroke, having it inhaled in a combustion chamber, and spraying this oxygen into the combustion chamber at the optional timing of a compression stroke before fuel combustion. CONSTITUTION: When intake air is inhaled in a combustion chamber 3, atmospheric air is inhaled through an air cleaner 8 whenever a piston 2 goes down. At this time, this air is subjected to a removal of oxygen O2 from the atmosphere for separation by an oxygen separator 17, making it into such a gas as containing no oxygen and, after premixing this intake air with fuel, it is inhaled into the combustion chamber 3 from an inlet port 5. Then this intake air is compressed in time of an ascent of the piston 2 after an inlet valve is closed, and at a point of optional time in the compression stroke, gas inclusive of oxygen regulated with content and temperature is pressurized by an injection pump 21 and sprayed out of an injection nozzle 16, whereby it is mixed with the fuel 10 being compressed and raised in temperature up to more than a self-ignition temperature into reaction for combustion.

摘要： PURPOSE:To separate efficiently a washed working fluid from a carbon dioxide absorbing liquid by providing a passage for an unwashed working fluid so that the flow direction of unwashed working fluid does not run against the direction of mists of carbon dioxide absorbing liquid scattering by centrifugal forces. CONSTITUTION:A casing 25 is provided downstream of a passage where mists of carbon dioxide absorbing liquids are sprayed on unwashed working fluids of a closed circuit type Diesel engine. In a space between double porous cylinders 51, 52, composed of inner and outer cylinder, rotating within said casing 25, partition walls 53 are radially disposed appropriately spaced from each other or mesh-like packings 58 are filled, wherein washed working fluids to separate the mists of carbon dioxide absorbing liquids are caused to flow from the lower part of the inside of the inner porous cylinder 51 through the holes thereof and through between the porous cylinders and are discharged upwardly therefrom. Consequently, washed working fluids and carbon dioxide absorbing liquids are efficiently separated from the unwashed working fluids on which carbon dioxide absorbing liquids have been sprayed.
