Abstract

Recently, diesel engine emissions have been designated as a first-class carcinogen by the World Health Organization (WHO). As such, problems with diesel engine emissions continue to increase around the world. This study aimed to analyze the emissions (CO, NOx, PM) of agricultural tractors during farming operations in order to build a reliable national inventory of air pollutant emissions. Emission data were collected using a portable emission measurement system during actual agricultural operation. The load factor (LF) of the engine was calculated using the collected engine information, the emission factor was analyzed using the LF and the measured emission. The LF was significantly different from the current standard value of 0.48, which is used in Korea to calculate exhaust emissions. The deviation ratio of the emission factor was 0.039 ~ 56.59 compared to Tier-4 emission regulation standards. Under many conditions, the calculated emission factor was higher than the emission limit. Thus, this study provides useful information for emission inventory construction through emission calculation under actual conditions and suggests the need to realize the currently applied emission factor.

摘要

最近，柴油发动机排放物被世界卫生组织（WHO）列为一类致癌物。因此，全球范围内柴油发动机排放问题持续增加。本研究旨在分析农用拖拉机在耕作作业期间的排放物（一氧化碳、氮氧化物、颗粒物），以便建立可靠的国家空气污染物排放清单。在实际农业作业期间，使用便携式排放测量系统收集排放数据。利用收集到的发动机信息计算发动机的负载因子（LF），并使用LF和测量到的排放来分析排放因子。该LF与韩国用于计算废气排放的当前标准值0.48有显著差异。与Tier-4排放法规标准相比，排放因子的偏差率为0.039至56.59。在许多情况下，计算出的排放因子高于排放限值。因此，本研究通过在实际条件下进行排放计算为排放清单构建提供了有用信息，并表明有必要实现当前应用的排放因子。
