1. Field of the Invention
This invention relates to an oxygen supply apparatus and more particularly to an apparatus for introducing oxygen into a combustion chamber of an engine.
2. Description of the Prior Art
The principle of a lean burning engine is that a combustion is carried out in a lean state in which the air/fuel ratio is equal to or greater than the stoichiometric value. Since the engine can be controlled with high efficiency and stable combustion at a lean condition, there has been a strong desire to realize such an engine in practice. In particular, the development of an automotive engine has been desired which can be efficiently and effectively operated in a lean burning mode.
In order to realize such a lean burning engine, it is necessary to introduce oxygen into a combustion chamber in a lean state. As means of oxygen supply, there are known a port injection type oxygen supplying means and an air fuel mixture introducing means.
In the port injection type oxygen supplying means, the oxygen is directly injected into the combustion chamber. In this case, it is necessary to inject the oxygen in a very large amount of oxygen at once. Therefore, it is not easy to actually introduce the necessary amount of oxygen into the combustion chamber in a short time.
In the air fuel mixture introducing means, the oxygen is introduced into the combustion chamber by means of an air fuel mixture. Generally, the air fuel mixture is formed by a fuel and air in a stoichiometric ratio. However, it is difficult to form the mixture in a stoichiometric ratio by combustion of be359ba680
