Abstract

Facing the risk of fossil fuel depletion and environmental pollution from
diesel engine exhaust, the study of using diesel-compressed natural gas (CNG)
dual fuel on current diesel engines has long been of interest. The problem is
whether the engine can ensure performance when switching to using D-CNG
dual-fuel or not. This paper presents the results of an experimental study to
evaluate the econo-technical characteristics of the current diesel engine when
using D-CNG dual-fuel based on the analysis of engine exergy efficiency and
emission characteristics. For this purpose, a Kubota SKD80 engine was converted
to experimentally study the use of D-CNG dual fuel with CNG fuel being fed into
the intake manifold and diesel being pilot fuel. The results of the analysis of the
engine's exergy performance at different load conditions show that when using
CNG, the exergy efficiency of the engine increases, the exergy loss and exergy
destruction are reduced, and smoke emissions are significantly reduced.
