Abstract
Over the last decade, the diesel engine has made dramatic
progress in its performance and market penetration. However, in
order to meet future emissions legislations, Nitrogen Oxides
(NOx) and particulate matters' (PM) emissions will
need to be reduced simultaneously. Nowadays researchers are focused
on different combustion modes which can have a great potential for
both low soot and low NOx. In order to achieve this,
different injection strategies have been investigated.
This study investigates the effects of split injection
strategies with high levels of Exhaust Gas Recirculation (EGR) on
combustion performance and emissions in a single-cylinder direct
injection optical diesel engine. The investigation is focused on
the effects of injection timing of split injection strategies.
A Ricardo Hydra single-cylinder optical engine was used in which
conventional experimental methods like cylinder pressure data, heat
release analysis and exhaust emissions analysis were applied.
Optical techniques like direct spray and combustion visualization
were applied by means of a high-speed imaging system with a copper
vapor laser illumination system and a high-speed two-color system
was applied to obtain in-cylinder diesel combustion temperature and
soot measurements distributions.
