Cool-flame extinction during n-alkane droplet combustion in microgravity
TL;DR: In this article, the authors report experimental observations of n-heptane, n-octane, and n-decane droplets of varying initial size burning in oxygen/nitrogen, oxygen/ nitrogen, oxygen-nitrogen/carbon dioxide, and oxygen/nocogen/helium environments at pressures from 0.5 to 1.0 ǫ atm.

An investigation of multiple spark discharge using multi-coil ignition system for improving thermal efficiency of lean SI engine operation
Dongwon Jung,Norimasa Iida +1 more
TL;DR: In this paper, the effects of multiple spark discharge on the combustion phasing and the combustion duration are examined for lean operation (excess-air ratio (λ) = 1.67) under a constant spark timing.

Investigation to charge cooling effect and combustion characteristics of ethanol direct injection in a gasoline port injection engine
TL;DR: In this article, the authors investigated the charge cooling effect and combustion characteristics of ethanol direct injection in a gasoline port injection (EDI+GPI) engine and found that the overall cooling effect of EDI was enhanced with the increase of ethanol ratio from 0% to 58%.
Journal ArticleDOI
Autoignition of gasoline surrogates at low temperature combustion conditions
TL;DR: In this article, the authors used a Rapid Compression Machine (RCM) to measure the ignition delay of a research grade gasoline (RD387), including a three-component mixture of iso-octane, n-heptane, and toluene and a four component mixture with the addition of an olefin (2-pentene).

Influence of turbulence–chemistry interaction for n-heptane spray combustion under diesel engine conditions with emphasis on soot formation and oxidation
TL;DR: In this paper, the influence of the turbulence-chemistry interaction (TCI) for n-heptane sprays under diesel engine conditions has been investigated by means of computational fluid dynamics (CFD) simulations.

High Combustion Temperature for the Reduction of Particulate in Diesel Engines
TL;DR: In this paper, the effects of temperature T and equivalence ratio Φ on soot formation at high pressures up to 5 MPa were investigated in a diesel engine and the trajectory in relation to both soot and NO formation region gives suggestion of a possibility of high temperature mixture combustion to reduce particulate formation in diesel engines.

Numerical study on the low emission window of homogeneous charge compression ignition diesel combustion
Sungwook Park,Rolf D. Reitz +1 more
TL;DR: In this article, a numerical study of the low emission window (lower than 10 grams/kg-f CO, 10g/kgf HC, 0.5 grams/ kg-f NO and almost soot-less) of diesel HCCI combustion was performed over wide ranges by changing equivalence ratio, inlet temperature, intake valve closure timing, engine speed and fuel amount.

Investigation of the Roles of Flame Propagation, Turbulent Mixing, and Volumetric Heat Release in Conventional and Low Temperature Diesel Combustion
Sage L. Kokjohn,Rolf D. Reitz +1 more
TL;DR: In this paper, a multi-mode combustion model that combines a comprehensive kinetics scheme for volumetric heat release and a level-set-based model for turbulent flame propagation is applied over the range of engine combustion regimes from non-premixed to premixed conditions.
