Test methods

With regard to studies on fuel economy and exhaust emission test methods and testing equipment, JARI investigates the allowable error of the chassis dynamometers and other equipment used to simulate the realworld driving conditions in the laboratory and proposes various improvements for minimizing the error. Currently worldwide discussion is underway to develop globally common test methods for fuel economy and exhaust emissions. JARI is involved in the international discussion and study on driving cycles, measuring methods and testing equipment in order to contribute to the development of globally unified test methods on fuel economy and exhaust emissions.
