Improvement of premixed charge compression ignition-based combustion by two-stage injection
International Journal of Engine Research, 2009The objective of this study is to find strategies for extending the load range of premixed charge compression ignition-based combustion while improving thermal efficiency and reducing combustion noise and exhaust emission levels. Experiments were performed using a single-cylinder direct-injection diesel engine equipped with a common-rail injection ...

Abstract Partially premixed charge compression ignition (PCCI) engine presents superior fuel economy and ultra-low NOx and particle matter emissions compared with the conventional combustion engine. The benefits of low emission of SI engine and higher thermal efficiencies of diesel engine are combined to meet the stringent emission regulations and ...

The charge mixture in a premixed charge compression ignition (PCCI) engine with direct in-cylinder injection early in the compression stroke is still heterogeneous even at the compression end. Direct injection of a low-volatility fuel, such as diesel fuel, early in the compression stroke results in adhesion of unevaporated fuel on the cylinder liner ...

Improvement of Combustion Process and Exhaust Emissions with Premixed Charge Compression Ignition
Journal of Automotive Powertrain and Transportation Technology, 2022Premixed Charge Compression Ignition (PCCI) is a combustion concept that is characterized by low temperature, partially premixed combustion using early injections, large ignition delays and high percentages of Exhaust Gas Recirculation. This review paper discusses the premixed charge compression ignition (PCCI) and the way to reduce the emissions.

Modeling Approaches for Premixed Charge Compression Ignition Combustion
SAE Technical Paper Series, 2005<div class="htmlview paragraph">The Representative Interactive Flamelet (RIF) - model has established itself as a model well suited for capturing conventional non-premixed combustion in diesel engines. There are concerns about applying the concept to model combustion modes characterized by high degrees of premixing, since it is argued that the ...
