| Summary: | A deep
understanding of the ignition characteristics of syngas-diesel under different
lambda values is essential for the application of dual-fuel combustion. In this
study, the effect of increasing the lambda value was examined along with the
emission characteristics and engine performance of syngas-diesel dual-fuel
engines under a constant syngas-to-diesel substitution ratio of 52% at 2000 rpm
engine speed. The work involved computational fluid dynamics analysis related
to combustion for a four-stroke single-cylinder direct-injection engine.
Combustion analysis was carried out using ANSYS Workbench (FLUENT) V16.1
software. According to the simulation results, the maximum pressure,
temperature, and nitric oxide emission inside
the combustion chamber increased with each increase in the value of lambda,
while the emission of carbon dioxide and carbon monoxide decreased inside the
engine. |
