In this study, a spectroscopic method was used to measure the combustion characteri stics of a test diesel engine when operated on dimethyl ether (DME) under a homogenous charge compression ignition (HCCI) combustion process. The results of the analysis showed that the methane additive influenced the auto-ignition timing in the DME-HCCI combustion process. In the experiments, the addition of methane enabled the DME-HCCI engine to provide crankshaft output equivalent to that seen for diesel engine operation at a low equivalence ratio. This paper discusses these effects in reference to the experimental and calculated results.
