TLDR
In this article, the effects of the injection timing, the exhaust gas recirculation rate and the load rate on the combustion and the heat release pattern were studied in a boosted six-cylinder heavy-duty diesel engine.Abstract:
Partially premixed compression ignition in a diesel engine is a combustion mode between diffusion combustion and homogeneous charge compression ignition combustion, the combustion controllability and the emission performances of which are close to those of a homogeneous charge compression ignition combustion engine; the mixing period plays a key role in realizing partially premixed compression ignition, and a long premixed process before combustion is necessary to make the fuel and air mix well. Partially premixed compression ignition combustion in a boosted six-cylinder heavy-duty diesel engine is realized by adjusting the injection timing and the rate of exhaust gas recirculation based on a single injection. The effects of the injection timing, the exhaust gas recirculation rate and the load rate on the combustion and the heat release pattern are studied. The factors which influence the mixing period and the ignition delay and its regularity are researched. Endoscope technology and the two-colour method...read more

Use of some advanced biofuels for overcoming smoke/NOx trade-off in a light-duty DI diesel engine
TL;DR: In this paper, the authors used three advanced bio-fuels with a low cetane number, viz. dimethyl carbonate (DMC), iso-butanol and n -pentanol with blend-ratios of 15, 38 and 45vol% in diesel, respectively (that corresponds to a uniform oxygen content of 8%) in a single-cylinder DI diesel engine.

Advanced compression-ignition engines—understanding the in-cylinder processes
TL;DR: The development of advanced compression-ignition (CI) engines can deliver both high efficiencies and very low NOX and particulate (PM) emissions, but unlike conventional diesel engines, the charge is highly dilute and premixed (or partially premixed) to achieve low emissions as mentioned in this paper.
