Experimental Study on Improving Gasoline Engine
Performance by Adding Hydrogen to Gasoline
Zhang JipengGao QingHao ijun
(Jilin Universit y of T echnology)
Abstract
,
D ring the comb stion process of gasoline engine adding some hydrogen partly has good ef-
fect on improvement of gasoline engine performance and red ction of exha st emissions. Some
changes of the excessive air ratio and ignit ion advanced tim ing after adding hydrogen, comb st ion
press re variat ion and som e problem s on economic performance and hydrocarbon and carbon
monoxide em ission are invest igat ed in this paper . The experim ental res lts show t hat the ignit ion
limit is enlarged w ith the increasing of hydrogen adding rat io . F rthermore, Beca se of t he rapid
, ,
comb st ion speed of hydrogen t he ignit ion delay period of the comb stible m ixt re is shorten t he
optim m ignit ion advanced t iming decreased, t he comb stion press re variation min m ized and the
content of HC and CO in the exha st gas is greatly red ced.
