Hydrogen has a potential alternative to conventional hydrocarbon fuels, because no CO_2 is emitted followed by combustion and it is able to make it by electroanalysis of water. This study aims to obtain stable ignition timing and combustion processes of hydrogen when it is applied into the direct-injection diesel engine. This report, it thought about the influence of the ambient conditions on the auto-ignition and combustion behavior of the hydrogen jet was investigated with a rapid compression and expansion machine (RCEM). First, the ambient temperature in combustion chamber is raised by adding argon into the ambient gas. Second, that is raised through the oxidation process of lean DME mixture. In addition, the effect of intermediates of DME reaction on the auto-ignition of hydrogen jet was investigated by use of CHEMKIN III code. Moreover, this effect was experimentally clarified.
