Abstract
In the present study, the combustion characteristics of methane and hydrogen-supplemented methane as alternative fuels for automotive vehicles were investigated at various hydrogen substitution rate, ignition position and ignition methods in a CVCC. As a result, it is possible to decrease the total burning time and to obtain the reduction of NO concentration by using MSCDI device under the lean mixture conditions without deteriorating combustion characteristics such as combustion efficiency, maximum combustion pressure etc.. And by mixing hydrogen into methane, it was found that the reduction of the total burning time was obtained, in comparison with the use of methane only ; and at the same time, the combustion promotion rate was improved remarkably in comparison with the use of methane only.
