Research Abstract	It was found that NOx and CO are reduced by the injection of NO highly concentrated into an engine intake. The injection was also found to slightly reduce the specific fuel consumption of the engine. Moreover, the exhaust-gas purification system for a real engine was developed with a TSA that made highly concentrated NO from NOx in exhaust gas. The purification of the exhaust gas succeeded with such the system. Because is not accompanied with the increase in fuel consumption or purchasing cost of reducer chemical, this technique is the one that can utilize the high thermal efficiency of diesel engines and has a large social meaning.
