In light-duty direct-injection (DI) diesel engines, combustion chamber geometry influences
the complex interactions between swirl and squish flows, spray-wall interactions, as well as …

A computationally efficient spray model is presented for the simulation of transient
vaporizing engine sprays. It is applied to simulate high-pressure fuel injections in a constant …

The work presented here experimentally investigates the effect of pilot quantity (PQ) on
combustion, performance and emission characteristics of an automotive diesel engine. All …

ABSTRACT A pilot-main injection strategy is investigated for a part-load operating point in a
single cylinder optical Diesel engine. As the energizing dwell between the pilot and main …

In light-and medium-duty diesel engines, piston bowl shape influences thermal efficiency,
either due to changes in wall heat loss or to changes in the heat release rate. The relative …

While the flow structure in the conventional, re-entrant combustion chamber is dominated by
a single toroidal vortex, the turbulent flow evolution in the stepped-lip combustion chamber …

Effect of spray/wall interaction in a rapid compression and expansion machine on mixture
formation, ignition location, and soot generation was investigated. A two-dimensional piston …

In order to explore the potential of thermal efficiency improvement of diesel engines with
injection rate shaping, TAIZAC (TAndem Injectors Zapping ACtivation) injector consisting of …

In-cylinder pressure-based heat release analysis and flow characteristics were used to
investigate the effect of bulk flow and mixture stratification on combustion in a CI engine …

Fuel injection rate laws are one of the most important pieces of information needed when
modeling engine combustion with computational fluid dynamics. In this study, a simple …
