Skeletal CH3OH/NOx Kinetic Model for Simulating Spark-Ignition and Turbulent Jet Ignition Engines [PDF]

ACS Omega
Methanol is a promising renewable fuel for achieving a better engine combustion efficiency and lower exhaust emissions. Under exhaust gas recirculation conditions, trace amounts of nitrogen oxides have been shown to participate in fuel oxidation and impact the ignition characteristics significantly.

A Novel One- and Zero-Dimensional Model for Turbulent Jet Ignition [PDF]

Flow, Turbulence and Combustion, 2021
AbstractTurbulent jet ignition (TJI) is a promising combustion technology for burning highly diluted air-fuel mixtures. Computationally efficient models to assess the effect of the operating conditions and design parameters on the ignition propensity and timing are of paramount importance for the development of combustion systems employing TJI. To this

Combustion of turbulent lean mixtures by plasma jet ignition.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1989
In order to confirm quantitatively the performance and characteristics of the plasma jet ignition in turbulent lean mixtures, combustion tests were carried out with varying the governing parameters of the plasma jet ignition. three plasma cavity sizes of 37, 75, and 170 mm3, three orifice diameters of 1, 2, 5 and 4 mm, and three discharge energies of 0.

The impact of gasoline formulation on turbulent jet ignition

Fuel, 2022
Turbulent jet ignition (TJI) is a promising technology for burning ultra-lean mixtures; the process is comprised of hot reactive jets issuing from a pre-chamber (PC) and initiating combustion in the main chamber (MC). The present study employs a simplified zero-dimensional (0D) partially stirred reactor (PaSR) model to describe the complex mixing and ...
