Journal ArticleDOI
Experimental study on ammonia/hydrogen/air combustion in spark ignition engine conditions
Charles Lhuillier,Charles Lhuillier,Pierre Brequigny,Francesco Contino,Christine Mounaïm-Rousselle +4 more
TL;DR: In this article, an experimental study of a spark ignition engine with premixed ammonia/hydrogen/air mixtures is presented, showing that up to 20% hydrogen in the fuel by volume improves the cyclic stability and avoids misfires.
Journal ArticleDOI
An experimental and modeling study of ammonia with enriched oxygen content and ammonia/hydrogen laminar flame speed at elevated pressure and temperature
Krishna Prasad Shrestha,Charles Lhuillier,Charles Lhuillier,Amanda Alves Barbosa,Pierre Brequigny,Francesco Contino,Christine Mounaïm-Rousselle,Lars Seidel,Fabian Mauss +8 more
TL;DR: In this paper, a newly compiled kinetic model was developed for the prediction of the oxidation of ammonia and ammonia-hydrogen blends in freely propagating and burner stabilized premixed flames, as well as in shock tubes, rapid compression machines and a jet-stirred reactor.
Journal ArticleDOI
Experimental investigation on laminar burning velocities of ammonia/hydrogen/air mixtures at elevated temperatures
Charles Lhuillier,Charles Lhuillier,Pierre Brequigny,Nathalie Lamoureux,Francesco Contino,Christine Mounaïm-Rousselle +5 more
TL;DR: In this article, the authors introduced new laminar burning velocity data for ammonia/hydrogen/air mixtures measured by means of the outwardly propagating spherical flame method at atmospheric pressure, for previously unseen unburned gas temperatures ranging from 298 to 473 K, hydrogen fractions ranging from 0 to 60 V in the fuel and equivalence ratios in the range [0.8-1.4].
Journal ArticleDOI
Experimental investigation on ammonia combustion behavior in a spark-ignition engine by means of laminar and turbulent expanding flames
TL;DR: In this article, the combustion behavior of a single-cylinder spark-ignition engine with a constant-volume vessel at engine-relevant conditions of 445 K and 0.54 MPa was investigated.
Journal ArticleDOI
Ammonia as fuel for low-carbon spark-ignition engines of tomorrow's passenger cars
TL;DR: In this paper, the potential of ammonia as a fuel for spark-ignition engines is discussed, thanks to the studies carried out so far and to point out directions for future work.
