An updated assessment of "ne particle emissions from lightand heavy-duty vehicles is needed due to recent changes to the composition of gasoline and diesel fuel, more stringent emission standards applying to new vehicles sold in the 1990s, and the adoption of a new ambient air quality standard for "ne particulate matter (PM 2.5 ) in the United States. This paper reports the measurement of emiss...

This paper aims to study the characteristics of greenhouse gas (GHG) emissions from heavy-duty trucks in the Beijing-Tianjin-Hebei (BTH) region, which is located in Northern China. The multiyear emissions of GHG (CO2, CH4 and N2O) from heavy-duty trucks fueled by diesel and natural gas during the period of 2006–2015 were compared and analyzed. The results show that the GHG emissions from heavy-...

Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...

For the safety problem of heavy duty vehicles running on long downhill sections, a model was built for the application of engine brake and service brake combination based on test results. And a model of brake temperature rise for heavy duty vehicles running on long downhill sections was also established. For different braking modes, gear positions, speed and downhill slopes, brake temperature r...
