第二次世界大战结束后,发动机趋向采用短行程。至于短行程的优缺点,曾有两篇文章分剧发表过新的见解,本文对上述两文作了综述。 1960年柏林工业大学机器制造系的Riccius在论文中报导了发动机气缸容积为650厘米~3的试验测定,并进行了行程缸径比为0.921,0.655,0.5与0.4的选择。测定了不同行程缸径比压缩压力、摩擦功、平均有效压力、有效功率及单位燃油消耗率的影响。获得这些资料以前,本文两作者曾分别进行了结构的研究和试验研究,试验了行程缸径比对结构
After the end of World War II, the engine tended to adopt a short stroke. As for the shortcomings of the advantages and disadvantages, there have been two articles published drama new ideas, the paper reviewed the above two articles. In 1960, Riccius, a professor at the Department of Machine Building at the Technical University of Berlin, reported in the paper a test of an engine cylinder volume of 650 cm -3 and a choice of runway bore ratios of 0.921, 0.655, 0.5 and 0.4. The influences of different bore diameters on compression pressure, friction work, average effective pressure, effective power and unit fuel consumption rate were measured. Prior to obtaining these data, the authors of this paper have carried out structural studies and experimental studies, respectively, to test the cylinder bore alignment structure
