The role of detailed chemical kinetics on CFD diesel spray ignition and combustion modelling

Spray ignition and flame stabilisation in the frame of diesel-like combustion conditions combine fundamental and complex physical and chemical processes. In this work, a numerical investigation has been performed to evaluate the potential of integrating detailed chemistry into CFD calculations, in order to improve predictions and gain more insight in involved processes. This work has been carri...

The effect of hydrogen and nitrogen addition on heavy duty diesel engine emissions under reactivity controlled compression ignition combustion

The aim of this study is to evaluate a heavy duty diesel engine operation under reactivity controlled compression ignition combustion fueled with diesel oil and natural gas enriched with hydrogen and nitrogen addition. In this study, a single cylinder heavy– duty diesel engine is set to operate at 9.4bar gross IMEP (Mid- Load). The amount of injected diesel oil per cycle into the engine combust...

Active Combustion Control of Diesel HCCI Engine: Combustion Timing

We propose a model based control strategy to adapt the injection settings according to the air path dynamics on a Diesel HCCI engine. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the start of combustion. For that purpose, start of injection is adjusted based on a Knock Integral Model and intake manifold conditions. Experimental results ...

Investigation of the Ignition and Combustion Processes of a Dual Fuel Spray under Diesel-like Conditions using CFD Modeling

Recent research activities in the field of Diesel engines have shown the potential to reduce pollutant emissions and improve thermal efficiency by controlling fuel reactivity. However, understanding the impact of blending fuels with different physical and especially chemical properties on diesel-like spray mixing and combustion processes is still a challenge. Since the experimental techniques a...

Revisit of Diesel Reference Fuel (n-Heptane) Mechanism Applied to Multidimensional Diesel Ignition and Combustion Simulations

ABSTRACT Two reduced n-heptane mechanisms, previously developed in 1998 (40 species and 165 reactions) and in 2000 (65 species and 273 reactions) respectively, were revisited and the mechanism improvement was pursued. In the newly revised version, the mechanism consists of 83 species and 445 reactions. The mechanism was validated against the auto-ignition delay times of n-heptane/air mixture me...
