根据GB19756—2005《三轮汽车和低速货车用柴油机排气污染物排放限值及测量方法》对排放时限的要求,结合企业生产及产品技术水平,对该排放标准的实现进行了可行性分析,同时提出了若干满足该标准要求的技术改进措施,认为:农用单缸柴油机虽然是技术含量较低的一种机型,但是,通过一定的技术改进提高,其排放性能能够达到国标GB19756—2005第II阶段的排放要求。
According to the requirements of GB19756-2005 “Limits and Measurement Methods for Emission of Exhaust Pollutants from Diesel Engines for Three-wheeled Vehicles and Low-speed Freight Cars” and on the basis of the requirements of the time limit and the technical level of production and products of the enterprises, the feasibility of the emission standards is analyzed. At the same time, a number of technical improvement measures to meet the requirements of this standard are put forward. It is considered that although the agricultural single cylinder diesel engine is a low-tech model, its emission performance can reach GB GB19756-2005 Stage II emission requirements.
