Abstract

This paper studies the combustion, performance and emission characteristics for one of the advanced engines
called partially premixed charge compression ignition engine by using blends of diesel and biodiesel fuel. The
partially premixed charge compression ignition engine is one of the homogenous charge compression ignition
engines which aim to reduce the temperature of the ignition, improve the performance of the engine and reduce
the emitting emissions. The experiment is performed in a four-stroke constant speed and air cooled diesel engine
which is modified by using intake manifold to work as partially premixed charge compression ignition engine.
From the experiment it was observed reduction in the emissions of engine like NOx emission by over 40% of
values in particles per minute compared with the conventional diesel engine and by over 60% of values in
particles per minute using 30% blend of biodiesel also increasing in the brake thermal efficiency in the two cases
of using diesel fuel by over 10% or using 30% blend of biodiesel and diesel by over 30%.
