Benefits of E85 versus gasoline as low reactivity fuel for an automotive diesel engine operating in reactivity controlled compression ignition combustion mode
TL;DR: In this article, the capabilities of E85 fuel to be used as low reactivity fuel in a high compression ratio light-duty diesel engine (17.1:1) running under reactivity controlled compression ignition concept was investigated.
Journal ArticleDOI
Exploring the limits of the reactivity controlled compression ignition combustion concept in a light-duty diesel engine and the influence of the direct-injected fuel properties
TL;DR: In this article, the authors investigated the operational limits of the reactivity controlled compression ignition combustion concept in a light-duty single-cylinder diesel engine using the stock compression ratio (17.1:1) with specific constraints.
Journal ArticleDOI
Performance of a conventional diesel aftertreatment system used in a medium-duty multi-cylinder dual-mode dual-fuel engine
TL;DR: In this article, the authors evaluate the efficiency of a commercial aftertreatment system (DOC+DPF) while operating in dual-mode dual-fuel combustion and evaluate the performance of active and passive regeneration processes.
Journal ArticleDOI
Potential of e-Fischer Tropsch diesel and oxymethyl-ether (OMEx) as fuels for the dual-mode dual-fuel concept

TL;DR: In this paper, a compression ignition multi-cylinder medium-duty engine was tested with a dualmode dual-fuel combustion strategy and the results showed that the higher oxygen content of OMEx allows reducing the soot emissions at high loads to near zero levels, while e-FT promotes a soot reduction of around 20% as compared to diesel.
Journal ArticleDOI
Swirl ratio and post injection strategies to improve late cycle diffusion combustion in a light-duty diesel engine
TL;DR: In this article, the authors compared different engine strategies to enhance the late cycle mixing controlled combustion process and therefore enhance soot oxidation while maintaining similar gross indicated efficiency in a light-duty diesel engine.
