Methods for in-cylinder EGR stratification and its effects on combustion and emission characteristics in a diesel engine
TL;DR: In this article, the effects of in-cylinder EGR stratification on combustion and emission characteristics are investigated in a single cylinder direct injection diesel engine, where external EGR rates of two intake ports are varied by supplying EGR asymmetrically using a separated intake runner.
Journal ArticleDOI
Effect of the diesel injection strategy on the combustion and emissions of propane/diesel dual fuel premixed charge compression ignition engines
TL;DR: In this paper, the effects of the propane ratio and diesel direct injection strategy on the emissions and combustion characteristics of a propane-diesel dual fuel PCCI (premixed charge compression ignition) engine were evaluated.
Journal ArticleDOI
Emission reduction potential in a light-duty diesel engine fueled by JP-8
TL;DR: In this paper, the effects of EGR (exhaust gas recirculation) and multiple injection strategy with two pilots on the emissions and combustion characteristics of JP-8 fueled light-duty diesel engine were systemically investigated.
Journal ArticleDOI
Comparison of the effects of multiple injection strategy on the emissions between moderate and heavy EGR rate conditions: part 1-pilot injections

TL;DR: In this paper, the effects of pilot injection on the engine-out emissions were systemically evaluated for two different EGR rate conditions (30% and 60%) and the characteristics of the pilot injection were different between the two EGR rates.
Journal ArticleDOI
Reduction of emissions with propane addition to a diesel engine
TL;DR: In this article, the performance of dual-fuel combustion with a low air-fuel ratio (AFR), which implies a low intake pressure, was evaluated using propane in a diesel engine.
