摘要
列举醇类、醚类、酯类、生物柴油等及其作为含氧燃料添加剂与汽、柴油混合的混合燃料性能,介绍部分纯质含氧燃料及其混合燃料对内燃机燃烧和排放的影响。研究表明,醇类燃料及其与汽油的混合燃料能够降低点燃式发动机的HC和CO排放,使发动机的动力性和经济性提高;二甲醚燃料、柴油与DMC或ADMM等的混合燃料对降低压燃式发动机的微粒排放具有显著的作用。含氧化合物混入燃油中有利于降低内燃机中HC,CO等物质的排放。
This paper introduces the characteristics of alcohols,ethers. esters, bio-diesel as well as their blends with gasoline or diesel.
Their effects on engine combustion and emission are reviewed. Alcohols and their mixture with gasoline can decrease the emission of HC,
CO and improve the performance and fuel economy of SI engine. DME and the oxygenated diesel with DMC or ADMM can significantly
reduce PM emission from CI engines. The oxygenated fuels have the advantages of low HC and CO emissions.
