As the emission regulation is getting more stringent all over the world, it is requested that the conditions of a test vehicle on road are exactly simulated on a chassis dynamometer. An existing twin roll is replaced with a single roll on a chassis dynamometer for this request. Especially in the nations using CVS-75 mode as an emission regulation, road load is increased 10% for considering air conditioners. But it is not clearly described about 10% up condition on road load for CVS-75 mode using a single roll chassis dynamometer. We studied on the effect of road load on fuel economy of CVS-75 mode according to road load setting conditions on a single roll chassis dynamometer.

To cope with the Green house effect, CO2 regulation is getting started all over the world. Automakers have been trying to find practical way to reduce CO2 from their vehicles. But it takes too much time and money to improve the vehicles effectively. In the case that the gear shift pattern of a manual transmission vehicle isn t determined like Korea & North America, driver's gear shift pattern could cause significant difference in fuel economy as well as CO2 emission. We studied on the effect of fuel consumption rate with the change of gear shift pattern in FTP75 test mode and proposed a method to find optimized shift pattern for maximum fuel economy.
