carbon dioxide/natural gas mixture on the performance characteristics of an
Internal Combustion Engine (ICE) is carried out. Generally, the presence of
high carbon dioxide content in natural gas reduces the heating value of the
mixture when compared with pure natural gas. This leads to reduction in the
burning velocity which ultimately affects the engine output and thermal efficiency.
However, there is an improvement in the NOX emissions while unburnt
hydrocarbon and carbon monoxide are on the increase. Different techniques to
improve engine performance were suggested and carried out. In addition to this,
a direct injection fuel delivery system together with maintaining the air flow
ratio is proposed as a way engine performance may be improved and emissions
are reduced.]]>Das, L., R. Gulati and P.K. Gupta,200025783793Hu, E., Z. Huang, B. Liu, J. Zheng and X. Gu,20093410351044Ghasemi, A. and M.H. Djavareshkian,20101013691379Anbese, Y.T., A.R.A.
