The modeling of combustion or, to be exact, turbulent combustion using numerical
simulation has become state-of-the-art in the process of developing internal combustion …

Government regulations on vehicle tailpipe emissions have steadily become more stringent
in the last few decades, mainly to reduce gaseous and particulate pollutants from internal …

Open-cycle engine simulations of a passive pre-chamber operating inside a direct-injected
gasoline engine are performed and analyzed in this study. A comprehensive three …

Emissions reduction through engine efficiency improvements is a priority for automakers
who have turned to unconventional engine operation such as highly dilute, boosted, and …

The spark discharge of an aircraft plasma jet igniter is studied using high-fidelity numerical
simulations and X-ray radiography measurements. The target problem here features the …

With the heightened pressure on car manufacturers to increase the efficiency and reduce the
carbon emissions of their fleets, more challenging engine operation has become a viable …

A spark plug calorimeter is introduced for quantifying the thermal energy delivered to
unreactive gas surrounding the spark gap during spark ignition. Unlike other calorimeters …

As a novel ignition approach, nanosecond repetitively pulsed discharge (NRPD)-based non-
thermal plasma offers significant benefits such as low energy consumption, and lean …

Lean combustion has the potential to improve the thermal efficiency of spark-ignition
engines, but it faces the significant challenge of increased cycle-to-cycle variation due to low …

In the United States transportation sector, Light-Duty Vehicles (LDVs) are the largest energy
consumers and CO2 emitters. Electrification of LDVs is posed as a potential solution, but SI …
