Abstract

The ratio of diesel vehicles in vehicle park and also the number of
diesel vehicles sharply increase in the world. Advantages of diesel engines can
be stated as high efficiency, low fuel consumption etc., on the other hand high
amount of oxides of nitrogen caused by high compression ratio of diesel engines
should be noted as its disadvantage.    Moreover, a high amount of smoke emission is
formed due to combustion characteristics of diesel engines. Both NOx and smoke
are really hazardous for the environment. Stringent emission regulations force
diesel engines to exhaust less NO_x and smoke emissions. Thus, diesel
engines require advanced after - treatment systems. The catalyst materials in
after - treatment systems are really expensive. In this study, different levels
of hydrogen [0%, 40% and 75%] on energy basis of total fuel were introduced
into intake manifold of engine. Brake thermal efficiency of the engine improved
with increasing percentage of hydrogen. CO, THC and smoke emissions are
significantly decreased by using hydrogen as additional fuel. Especially, a
novel decrease on smoke emission [up to 70.7%] is obtained. However,
particularly during 75% hydrogen addition, the dramatic increase in NO_x
emissions could not be prevented.
