Özet:

 


In
this study, engine performance, combustion and emissions a diesel engine used
for driving an electrical generator was investigated with LPG fumigation into
the manifold of the engine as secondary fuel. Tests were carried out in 4
cylinders, 4 strokes water-cooled and direct-injection diesel engine generator.
According to the test results; cylinder pressure, average gas temperature and
peak values of heat release rate were increased as amount of LPG was increased.
However, brake specific fuel consumption and mass fuel consumption were higher.
Generally, with LPG addition, CO and HC emissions were found higher. Up to 40%
LPG addition, CO2 emissions were lowered and over 40% LPG addition,
CO2 emission increased. With increasing LPG ratio, there was a
decrease in NOx emission values. On the other hand, generally, as LPG content
was increased, O2 emissions were decreased significantly. Generally,
the usage of LPG until certain levels found to be possible as secondary fuel in
diesel engines. However, its usage in the engine up to certain levels resulted
in considerable negative changes in performance, combustion and emissions
changes. Over 55% LPG fumigation resulted in quite high flame velocity and
propagation which eventually resulted in the accelerated pressure increase for
per crank angle. This condition may be accepted as the starting of the knock.
Therefore, only certain low amounts of LPG usage as secondary nonreactive fuel
in diesel engine were found to be possible.
