Legislations for greenhouse gas and pollutant emissions from light-duty vehicles are
pushing the spark ignition engine to be cleaner and more efficient. As one of the promising …

Prechamber-assisted internal combustion engines allow lean limit extension by replacing
the spark plug with multiple, high-temperature, radical-rich jets that entrain and ignite the …

In this paper, the combustion characteristics of premixed CH 4-air and H 2-air mixtures with
different excess air coefficients ignited by hot jet or jet flame are investigated experimentally …

The recent demand for reducing pollutant and CO2 emissions from internal combustion
engines has created an urgent need for the development of ultra-lean burn engines that …

A numerical investigation was conducted to study ignition and the initial phases of methane
combustion in a two-dimensional setup consisting of a pre-(PC) and main (MC) chamber …

Turbulent jet ignition (TJI) is a promising strategy to ignite diluted air-fuel mixtures; this is
usually generated by igniting a fraction of the mixture inside a small pre-chamber …

The search for new combustion systems makes the two-stage combustion system (TJI)
widely used when burning poor mixtures of methane and, increasingly, hydrogen. This …

Pre-chamber turbulent jet ignition is a promising high-efficiency combustion technique to
achieve stable lean-burn operation for spark-ignition engines. Wall impingement by a high …

Methanol spray impingement, mixing, flame propagation and jet evolution within the narrow-
confined active pre-chamber (APC) with complex walls were experimentally observed by …

The traditional method using spark electrode ignition in annular combustors lacks safety due
to its long ignition delay and deficiencies in reliability and repeatability. The present work …
