本発明は燃焼室に供給する空気中の酸素濃度を増加して
、燃焼温度を上昇させ、効率的な燃焼を行なわせる酸素
富化燃焼に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to oxygen-enriched combustion that increases the oxygen concentration in the air supplied to the combustion chamber to raise the combustion temperature and perform efficient combustion. It is something.

ところで、自動車エンジンの燃焼効率をアップさせる手
段として、酸素富化空気を燃焼室番こ供給して燃料の完
全燃焼を行なわせることが考えられている。このような
場合、酸素富化空気を得るための手段としては、膜分離
による方法が最適である。By the way, as a means of increasing the combustion efficiency of an automobile engine, it has been considered to supply oxygen-enriched air to the combustion chamber to achieve complete combustion of the fuel. In such cases, membrane separation is the most suitable means for obtaining oxygen-enriched air.
燃焼に使用する空気の酸素濃度が低いとエンジンの出力
が増大せず、逆に酸素濃度が高いと不安定燃焼を起こす
という問題があった。If the oxygen concentration of the air used for combustion is low, the output of the engine will not increase, and if the oxygen concentration is high, unstable combustion will occur.
このため、本発明の目的は、酸素濃度を適切な値に維持
することのできる簡単な制御方法を提供することである
。Therefore, an object of the present invention is to provide a simple control method that can maintain the oxygen concentration at an appropriate value.
混合空気中の酸素濃度を測定し、その信号で大気空気の
入口のベーンの開度を調節することにより、混合空気中
の酸素濃度を制御しようとするものである。The purpose is to control the oxygen concentration in the mixed air by measuring the oxygen concentration in the mixed air and adjusting the opening degree of the vane at the atmospheric air inlet based on the signal.
膜分離における酸素富化空気の圧力損失は、空気濾過器
を通る大気空気の圧力損失より大きいから、大気空気側
にベーンを設置して調節することにより、大気空気と酸
素富化空気の割合を調節することができる。The pressure loss of oxygen-enriched air during membrane separation is greater than the pressure loss of atmospheric air passing through an air filter, so by adjusting the ratio of atmospheric air to oxygen-enriched air by installing vanes on the atmospheric air side. Can be adjusted.
本発明の実施例を第1図に示す。 An embodiment of the invention is shown in FIG.

器6でガソリンと混合し、エンジンの燃焼室7に入って
燃焼する。Atmospheric air is taken in through an air intake port 1, dust is removed by an air filter 2, and the flow rate is adjusted by vanes 3 before entering a vaporizer 6. The membrane separation device 5 is composed of a tubular separation membrane that preferentially transmits oxygen, and the oxygen-enriched air that permeates inside the tube of the tongue-shaped separation membrane is mixed with air taken in from the atmosphere and sent to a vaporizer. Enter 6. The oxygen concentration is measured with an oxygen analyzer 4 installed in the mixing section of atmospheric air and oxygen-enriched air.
The oxygen concentration of the mixed air is automatically controlled by adjusting the vane 3 so as to eliminate the difference between this concentration and the target value. The mixed air is mixed with gasoline in a carburetor 6, enters a combustion chamber 7 of the engine, and is combusted.
本発明によれば、混合空気中の酸素濃度を自動制御する

た高出力を得ることができる。According to the present invention, it is possible to automatically control the oxygen concentration in the mixed air, so oxygen-enriched air created by membrane separation can be sent to the engine at a constant concentration, resulting in stable high output. be able to.
第1図に本発明の概略図を示す。 FIG. 1 shows a schematic diagram of the present invention.
