本文介绍了两种12缸机车柴油机在稳态工况下的气体和颗粒排放物数据。这两种实验室试验研究用发动机分别是EMD645E3B和GE7FDL,标定功率都是1860kW,是北美机车的主型机。每种柴油机都经受了碳氢化合物(HC),一氧化碳(CO),氧化氮(NOx)及颗粒试验。均在包括机车8个手把位,外加空转、低空转及动力制动的所有稳态工况下测量了柴油机的废气排放物。文中报告了每种柴油机采用两种不同的柴油进行试验获得的废气排放物测值。这两种柴油分别是:硫含量为0.33％(重量)的基准柴油,硫含量为0.01％的低硫柴油。
This article describes the gas and particulate emissions data for two 12-cylinder locomotive diesel engines under steady-state conditions. The two laboratory test engine used are EMD645E3B and GE7FDL, the calibration power is 1860kW, North American locomotive is the mainframe. Each diesel engine has been tested for hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and particulates. Engine exhaust emissions were measured at all steady-state conditions including 8 hand positions of the locomotive, plus idle, low idle and dynamic braking. The paper reports emissions measurements of each diesel engine using two different diesel tests. The two types of diesel are respectively: a reference diesel with a sulfur content of 0.33% by weight and a low sulfur diesel with a sulfur content of 0.01%.
