Methane Enrichment of Syngas (H2/CO) in a Spark-ignition Direct-injection Engine: Combustion, Performance and Emissions Comparison With Syngas and Compressed Natural Gas

Syngas produced from gasification of solid fuels can serve best as transition fuel from the carbon-based to the hydrogen-based fuels in the internal combustion engines. The lone drawback is its low calorific value being between one tenth and one fifth of that of CNG (Compressed Natural Gas). This re...
