A control-oriented combustion model for a turbulent jet ignition engine using liquid fuel

, 2017
A control-oriented engine model is necessary for developing and validating the associated engine control strategies. For engines equipped with the turbulent jet ignition system, the interaction between the pre- and main-combustion chambers should be ...

AI Revolution and Warfare: A New Paradigm Shift in Defence Procurement, Restructuring, Training, and Recruitment

Canadian Public Administration, Volume 69, Issue 2, Page 250-277, June 2026.
Abstract The war in Ukraine and Israel's successful operations have demonstrated the apparent shift in military operations, strategic defence spending, and innovations. Drawing parallels to the industrial revolution and how it slowly transferred military procurement, training, and deployment, the current study also highlights the AI revolution and the ...

Pre-chamber ignition mechanism: Experiments and simulations on turbulent jet flame structure

, 2018
This work investigates the effects of premixed combustion kinematics in pre-chamber volumes on the development of emitted hot jets from the igniter. The effects of fuel type, orifice diameter, and ignition location are evaluated experimentally, with high-

Influence of In-Cylinder Turbulence Kinetic Energy on the Mixing Uniformity within Gaseous-Fuel Engines under Various Intake Pressure Conditions

Energies
To explore the potential for further enhancing the gas mixing uniformity of natural gas (NG) engines, this paper identifies turbulent kinetic energy (TKE), which has an essential impact on gas mixing, as the entry point of the research.
