“…One must be cautious when adjusting these parameters, as they affect not only the modeling of idling emissions, but also the energy consumption of the Class 8b combination longhaul trucks. For example, five Class 8 trucks showed idling fuel consumption varying from 0.5 to 1.8 gallons per hour (Storey et al, 2003). Limited studies were available to provide data on idling fuel consumption of HDVs (Brodrick et al, 2002;Frey and Kuo, 2009;Khan et al, 2006;Khan et al, 2009;Huai et al, 2006;Pekula et al, 2003).…”

“…It also affected the fuel economy by ϳ70%. Storey et al 8 examined idle emissions from five class 8 trucks, which were tested in the U.S. Army Aberdeen Test Center climate controlled chamber. Trucks were tested at both high and low idle speeds with varying accessory loading in different climate conditions.…”

Heavy-duty diesel vehicle idling consumes fuel and reduces atmospheric quality, but its restriction cannot simply be proscribed, because cab heat or air-conditioning provides essential driver comfort. A comprehensive tailpipe emissions database to describe idling impacts is not yet available. This paper presents a substantial data set that incorporates results from the West Virginia University transient engine test cell, the E-55/59 Study and the Gasoline/Diesel PM Split Study. It covered 75 heavy-duty diesel engines and trucks, which were divided into two groups: vehicles with mechanical fuel injection (MFI) and vehicles with electronic fuel injection (EFI). Idle emissions of CO, hydrocarbon (HC), oxides of nitrogen (NO x ), particulate matter (PM), and carbon dioxide (CO 2 ) have been reported. Idle CO 2 emissions allowed the projection of fuel consumption during idling. Test-to-test variations were observed for repeat idle tests on the same vehicle because of measurement variation, accessory loads, and ambient conditions. Vehicles fitted with EFI, on average, emitted ϳ20 g/hr of CO, 6 g/hr of HC, 86 g/hr of NO x , 1 g/hr of PM, and 4636 g/hr of CO 2 during idle. MFI equipped vehicles emitted ϳ35 g/hr of CO, 23 g/hr of HC, 48 g/hr of NO x , 4 g/hr of PM, and 4484 g/hr of CO 2 , on average, during idle. Vehicles with EFI emitted less idle CO, HC, and PM, which could be attributed to the efficient combustion and superior fuel atomization in EFI systems. Idle NO x , however, increased with EFI, which corresponds with the advancing of timing to improve idle combustion. Fuel injection management did not have any effect on CO 2 and, hence, fuel consumption. Use of air conditioning without increasing engine speed increased idle CO 2 , NO x , PM, HC, and fuel consumption by 25% on average. When the engine speed was elevated from 600 to 1100 revolutions per minute, CO 2 and NO x emissions and fuel consumption increased by Ͼ150%, whereas PM and HC emissions increased by ϳ100% and 70%, respectively. Six Detroit Diesel Corp. (DDC) Series 60 engines in engine test cell were found to emit less CO, NO x , and PM emissions and consumed fuel at only 75% of the level found in the chassis dynamometer data. This is because fan and compressor loads were absent in the engine test cell.

“…Foi utilizada a norma ISO 8178 e ensaiado um motor diesel de 4 cilindros. Storey et al [13] usaram um sistema de diluição similar ao de Shah et al, mas a amostra foi coletada apenas na marcha lenta do motor com uma vazão de 1 L/min durante 90 minutos.…”
