Compelling emission regulations and diesel engines damage on
environment have led researchers to work on alternative fuels such as LPG and
hydrogen in recent years. Diesel engine costs are also increasing, especially
on the increased costs of after-treatment equipment used in diesel engines. It
is also known that diesel engines release NO_x and smoke emissions,
which are highly harmful to the environment and to the living health. The
effect of the emissions of LPG + H₂ (0%, 15%, 30% and 45%) with
different energy contents at full load and same torque (70 Nm) at constant
engine speed of 1200 rpm is investigated on CO, THC, NO_x and Smoke
emissions. From the results obtained, there was a slight increase in brake
thermal efficiency, CO and THC emissions. However, significant improvement in
NO_x and smoke emissions has been achieved. The results show that
using LPG + H₂ in diesel engines, older technology and lower cost
after-treatment equipment can be used, and that NO_x and smoke
emissions of diesel engines can be reduced significantly. Also, using small
amount of hydrogen (20% of total gas mixture) and LPG, an important improvement
can be achieved, and the harmful effects of diesel engines can be suppressed
thanks to unique properties of hydrogen fuel.
