为了改善200柴油机的燃烧性能,降低柴油机的排温和油耗率,由戚墅堰机车车辆工厂、大连热力机车研究所、资阳内燃机车厂、西南交通大学等单位组成了燃烧攻关组,从1973年9月到12月,在200单缸机上进行了燃烧试验。一、试验目的根据前一阶段单缸机试验结果的分析,当时200柴油机在燃烧方面存在的主要问题是实际供油始点较晚,供油持续时间较长,从而出现过后燃烧现象,致使柴油机的排温和油耗率较高,冒黑烟现象严重。由于多缸机工作条件比单缸机差,所以排温和油耗问题在多缸机上
In order to improve the combustion performance of 200 diesel engines and reduce the exhaust temperature and fuel consumption rate of diesel engines, a combustion research group was formed by Qishuyan Rolling Stock Works, Dalian Thermal Power Locomotive Research Institute, Ziyang Diesel Locomotive Works, Southwest Jiaotong University and other units. From September 1973 to December 12 Month, burning test was carried out on 200 single cylinder machine. First, the purpose of the test According to the previous stage single cylinder test results analysis, when the 200 diesel engine in the combustion there is a major problem is the starting point of the actual fuel supply later, longer fuel supply, resulting in post-combustion phenomenon, resulting in diesel engine Pai warm and high fuel consumption, black smoke serious. Due to the multi-cylinder machine working conditions worse than the single cylinder, so the exhaust temperature and fuel consumption problems in the multi-cylinder machine
