Factors Leading to the Generation of Greenhouse Gazes emitted from Automobiles and Measures to Reduce These

		Factors Leading to the Generation of Grobal Warning Gases emitted from Automobiles and Measures to Reduce These

		In recent years, not only carbon dioxide, but also methane and nitrogen oxide (N2O) have gained attention as being greenhouse substances. We conduct research on methods for measuring these greenhouse substances, emissions from automobiles, overall N2O emissions from automobiles and measures to reduce such substances.
