Abstract

This project investigates the engine performance and exhaust emission of
dual-fuel operation on a single cylinder compression ignition engine. Natural gas is
used as the main gaseous fuel with diesel as the pilot fuel to provide a source of
ignition. The high compression ratios of diesel engines can be achieved without loss
in power together with substantial cost reduction in fuel and conversion kits.
Comparative results of dual-fuel operation with conventional diesel fuel through
experimental results demonstrated its benefits both in the fields of performance and
emission. The engine torque and brake power output show vast improvement and
dual-fuel operation is able to achieve a higher thermal efficiency under all operating
conditions. The emission levels of polluting gases such as carbon monoxide, oxides
of nitrogen (NOx) and carbon dioxide also records an enormous decrease.
