【摘要】 对影响现代轿车汽油机燃油经济性的诸因素，如：空燃比、点火提前角、压缩比、配气相位以及传动比等参数进行了深入的研究及相应的试验。在试验及分析的基础上，得到了在不影响动力性和排放等技术指标的前提下，改善现代轿车汽油机燃油经济性的途径。更多还原

【Abstract】 Some factors such as air/fuel ratio, ignition advanced angle, compression ratio, valve timing and transmission ratio, which affect the fuel economy of modern car gasoline engines have been studied in depth and the corresponding experiments have been done. Based on these experiments and analysis, the approach to improve the fuel economy of modem car gasoline engines without affecting engine power and exhaust emission performances has been found.更多还原
