Abstract
In decade years, due to lack of supply-demand balance of petroleum and
exhaust emissions within environmental pollution, researchers give more attention
to endeavor of using alternative fuels in internal combustion engines. Alternative
fuels have got their own behaviors and fuel properties that they affect the engine
when used as a fuel, comes by their advantages and disadvantages. It is very
important to know and investigate theirs fuel behavior and effects of combustion
and exhaust emissions.
In this study, HHO (Hydroxy-Oxyhydrogen) gas and CNG (Compressed Natural
Gas) mixtures used in CI (Compression-Ignition) engine as an addition fuels via
intake manifold and engine performance & exhaust emissions were investigated
experimentally. In experiments engine run under below three conditions; normal
diesel operation, 1,5%CNG+Diesel operation and 15%CNG+2,2%HHO+Diesel
operation respectively between 1200-2300 rpm engine speeds. Engine performance
and exhaust emission parameters explained and illustrated with graphics as engine
torque, specific fuel consumption and engine speed; CO, CO2
, NO, NO2
. The obtained
results are presented and compared each other.
It was observed that the enrichment of diesel engine with HHO-CNG mixtures
reduced the specific fuel consumption, CO2
and NOx, however increased the CO.
At the middle engine speeds addition of HHO to CNG prevent from the decreasing
the torque values. Additionally it was observed that HHO and/or CNG, improves
the level of engine noise and down the SO2
values to zero. As a result; this study
contains, how the engine performance and exhaust emissions changes with usage
of HHO and CNG enrichment in a CI engine, were investigated in detail.
