Experimental evaluation of on-road fuel consumption for a 2.2 L diesel-fueled vehicle at two driving routes

In this study, we investigated the RDE (real driving emissions) test with a diesel passenger vehicle and two RDE driving routes. We then experimentally analyzed the implications for fuel consumption of a 2.2L diesel-fueled vehicle. First, we found that the weighting factor, which is the product of t...

Description
Summary:In this study, we investigated the RDE (real driving emissions) test with a diesel passenger vehicle and two RDE driving routes. We then experimentally analyzed the implications for fuel consumption of a 2.2L diesel-fueled vehicle. First, we found that the weighting factor, which is the product of the carbon dioxide average value from the MAW (moving average window) analysis, results in real-road fuel consumption measurement that are closer to the WLTC (worldwide harmonized light vehicles test cycles) measurement results. Therefore, we ignored the weighting factor of the WLTC and used a new weighting factor of distance instead. In order to determine the influence of each factor on the fuel efficiency, we analyzed the carbon-dioxide emission for the operation of additional equipment. And OBD values were used to develop correction equations to compensate for vehicle driving regions where GPS data was not measured in the test route. When using the weighting factor based on the WLTC standard, the weighting factor based on distance was introduced to calculate the fuel consumption in this study.
