城市公交客车汽油\甲醇双燃料转换控制系统的研究

Study on the Control System of Fuel Shift between Petrol and Methylalcohol on City Buses

鉴于石油资源有限和汽车尾气是破坏人类环境的一大公害 ,不少国家纷纷出台限制汽车尾气排放的法规 ,使汽油汽车越来越难达到排放标准 .本文按我国计委公布将推广使用甲醇汽油这一比较洁净的能源的要求 ,大胆设想了一种甲 (乙 )醇汽油双燃料化油器 ,在启动发动机和重载爬坡时 ,以汽油为主 ,在超车加速时加喷汽油外 ,在其它工况运转时 ,则以醇类为主 ,能自动根据工况控制燃料转换供应 .

Seeing that the oil rescoures are limited and the tail gas of cars is a contamination of the environment ,many countries have laid down laws to restrict the emission of tail gas .Thus the cars which use petrol as fuel can hardly meet the standards .According to the demand of the usage of methylalcohol gas which is a kind of dean energy ,the author conceive a two-fuel carburetor .When the car is starting engine or climbing slopes with heavy loads, its main fuel is petrol. When the car is accelerating ,the main fuel is methylalcohol with spraying petrol .and in other cases methylalcohol plays a major part.
