Journal ArticleDOI
Effect of methane on pilot-fuel auto-ignition in dual-fuel engines
Aleš Srna,Michele Bolla,Yuri M. Wright,Kai Herrmann,Rolf Bombach,Sushant S. Pandurangi,Konstantinos Boulouchos,Gilles Bruneaux +7 more
TL;DR: In this paper, the ignition behavior of n-dodecane micro-pilot spray in a lean-premixed methane/air charge was investigated in an optically accessible Rapid Compression-Expansion Machine at dual-fuel engine-like pressure/temperature conditions.
Journal ArticleDOI
Experimental investigation of pilot-fuel combustion in dual-fuel engines: Part 1: Thermodynamic analysis of combustion phenomena
TL;DR: In this paper, the authors investigated the first-order influences of charge and pilot-fuel parameters on the ignition delay and transition into the premixed flame propagation in an optically accessible rapid compressionexpansion machine featuring quiescent charge conditions and a single-hole coaxial diesel injector mounted on the cylinder periphery.
Proceedings ArticleDOI
Influence of Injector Diameter (0.2-1.2 mm range) on Diesel Spray Combustion: Measurements and CFD Simulations
Journal ArticleDOI
Experimental investigation of pilot-fuel combustion in dual-fuel engines, Part 2: Understanding the underlying mechanisms by means of optical diagnostics
Aleš Srna,Beat von Rotz,Michele Bolla,Yuri M. Wright,Kai Herrmann,Konstantinos Boulouchos,Gilles Bruneaux +6 more
TL;DR: In this paper, a single-hole coaxial injector was used for pilot-fuel auto-ignition and combustion under engine-like conditions in compressed methane/air mixtures.
Validation and Initial Application of a Novel Spray Combustion Chamber Representative of Large Two-Stroke Diesel Engine Combustion Systems
Kai Herrmann,A. Kyrtatos,Reiner Schulz,German Weisser,B. von Rotz,Bruno Schneider,Konstantinos Boulouchos +6 more
TL;DR: In this article, a disk-shaped constant volume spray combustion chamber of diameter 500 mm with peripheral injection into a swirl-ing flow and equipped with comprehensive options for granting optical access has been realized, allowing the study of spray and combustion processes at conditions typical of large marine diesel engines.
