Reactivity Controlled Compression Ignition (RCCI), which is a low temperature combustion mode based on the principle of working with dual fuel, has attracted attention researchers in recent years due to its advantages such as high thermal efficiency, NOx and soot emissions, controllability combustion. In this study, effects injection timing lambda RCCI were investigated numerically by validatin...

Multiple injection strategies can be used for controlling the heat release rate in an engine, particularly compression ignition engines. This mitigate transfer losses and overcome limitation related to maximum pressure allowed a particular engine. Controlling with repetitive injections requires precise characterization of fuel rates. In such configuration, injector should characterized its hydr...

The purpose of this study is to investigate injection timing affected particle size distribution a diesel engine fueled with biodiesel/diesel blends. biodiesel blending ratios include 7, 10 and 20%vol. experiments were operated at speed 1,500 rpm under 25, 50 75% loads two different (25.5 CAD BTDC 27.5 BTDC). effects addition on the changes in black smoke discussed. Results showed that standard...

As anthropogenic activities continue to drive increases in extreme events, the fundamental solution of reducing greenhouse gas emissions remains elusive. Thus, there is growing interest stratospheric aerosol injection (SAI) offset some most dangerous consequences climate change. Although global SAI deployment would likely be easy detect by metrics, detectability on events might more difficult. ...

This paper presents the details of a Computational Fluid Dynamics methodology to accurately model process mixture preparation in modern Gasoline Direct Injection engines, with particular emphasis on liquid film as one main causes Particulate Matter formation. The proposed modelling protocol, centred Bai-Onera approach droplets-wall interaction and multi-component surrogate fuel blend models, is...
