Abstract: Ozone-assisted combustion has shown promise in stabilizing combustion and extending operating range of internal combustion engines. However, it has been reported that sensitivity of ozone quantity on combustion varies ...

Abstract: Steadystate port flow simulations were carried out with a commercial threedimensional (3D) computational fluid dynamics (CFD) code using Cartesian mesh with cut cells to study the prediction accuracy. The accuracy is ...

Abstract: In computational fluid dynamics (CFD) simulations of internal combustion engines, one of the critical modeling parameters is the valve setup. A standard workaround is to keep the valve opens at a certain clearance (minimum ...

Abstract: A comparative cold flow analysis between Reynoldsaveraged Navier–Stokes (RANS) and large eddy simulation (LES) cycleaveraged velocity and turbulence predictions is carried out for a single cylinder engine with a transparent ...

Abstract: Intake port flow performance plays a substantial role in determining the volumetric efficiency and in-cylinder charge motion of a spark-ignited engine. Steady-state flow bench and motored engine flow computational fluid ...

Abstract: Reliably starting the engine during extremely cold ambient temperatures is one of the largest calibration and emissions challenges in engine development. Although cold-start conditions comprise only a small portion of an ...
