摘要

以发动机4000r/min节气门开度35%为试验工况，对纯汽油、丙酮-丁醇-乙醇（acetone–butanol–ethanol，ABE）/汽油混合物ABE10（ABE容积比为10%，汽油容积比为90%）、ABE20和ABE30开展了不同点火提前角和喷油量的试验研究。分析了不同ABE混合比、点火提前角和过量空气系数对发动机性能的影响，并对每种燃料发动机最大功率工况的性能参数进行了比较。结果表明：点火提前角和过量空气系数相同时，混合燃料中ABE含量越多，燃油流量越大，发动机功率越大，有效热效率越高；燃油流量的总热量增大和热-功转换效率提高是促使发动机功率增大的主要原因；随ABE掺混比增加，一氧化氮（nitric oxide，NO）比排放明显降低，一氧化碳（carbon monoxide，CO）比排放略有增加，碳氢化合物（hydrocarbon，HC）比排放先增后减。浓混合气工况增加ABE含量比当量空燃比时增加ABE含量，发动机的有效热效率增大更明显，发动机的NO比排放降低更加明显。研究表明高速汽油机掺混ABE燃料具有较好的应用前景。

Abstract

The engine tests were carried out in different spark timing and fuel mass of injection under the operation condition of 4000r/min and throttle position 35%

four types of fuels pure gasoline

acetone–butanol–ethanol (ABE)/gasoline blends ABE10 (10 %vol ABE blended with 90 %vol gasoline)

ABE20 and ABE30. The effects of the ABE blend ratio

spark timing and lambda on the engine performance were analyzed. The performance parameters of each fuel engine at maximum brake power were compared. The results indicated that the fuel mass flow rate

the engine power

the brake thermal efficiency increase with increasing the ABE blend ratio at a given spark timing and lambda. The increase of the total heat of the fuel flow and heat-work conversion efficiency are the main reasons for the increase of the engine power. With the increase of the ABE blend ratio

nitric oxide (NO) emission decreased significantly; carbon monoxide (CO) emission increased slightly

hydrocarbon (HC) emission increased first and then decreased. The brake thermal efficiency of the engine increases more obviously under the fuel-rich operating condition than that of the stoichiometric air-fuel ratio. However

the NO emission of the engine decreases more obviously in the same situation. The research shows that the high-speed gasoline engine fueled with ABE-gasoline blends has a good application prospect.
