Abstract: A method and apparatus for reducing the emissions and improving the performance of an internal combustion engine (40). An input air stream is separated into an oxygen-enriched air stream and a nitrogen-enriched air stream. The nitrogen-enriched air stream is received by a holding chamber (35). The oxygen-enriched air and a combustible fuel are provided to a combustion chamber (45) of the internal combustion engine (40) and a combustion process is initiated. After a predefined time delay, a volume of nitrogen-enriched air is provided from the holding chamber (35) to the combustion chamber (45) to be used during the rest of the combustion process.

Abstract: A method for obtaining a product from pre-alloyed powders in which the powders are subjected to compaction treatment. The powders are first subjected to pre-treatment under low pressure (or without pressure) at a temperature such that segregating materials precipitate out in stable phases.

Abstract translation: 从粉末进行压实处理的预合金粉末中获得产品的方法。 粉末首先在低压（或无压力）下进行预处理，使得分离材料在稳定的相中沉淀出来。
