%X The purpose of this study is to simulate transient fuel consumption and gas emissions of a heavy duty diesel vehicle in the real world. A new simulation methodology for heavy duty diesel vehicles was developed based on the principles of power demand and transmission system in real world systems. To validate the methodology, a heavy duty diesel bus was selected to be tested on its business route by using an on-board emission measurement system. The fuel economy was 16.38 L·100 km-1. NOx, CO and THC emission factors reached 4.44, 3.35, and 1.96 g·km-1, respectively, and the simulated results were generally in accord with the test data. The fuel and emission factors were 1.06 times the test results. The proportions of driving condition under idling, NOx control zone and other zones of the engine map were 32.6%, 7.1% and 60.4%. If we increase the 10t load or speed up the velocity by 1.5 times, the engine load in the NOx control zone will increase to 18.4% and 18.8%, and the fuel and emission level will be 1.5~1.7 times or 1.6~1.8 times the base case. While integrating these two scenarios, the vehicle will be operated under a high stress load. The share of driving conditions under the NOx control zone will be 33.9%, and the fuel and emission level will increase to 2.5~3.0 times correspondingly. The simulation methodology can be utilized to analyze the second-by-second energy consumption and exhaust gas emissions for heavy duty diesel vehicles in the real world.
