Pre-chamber turbulent jet ignition technology is an effective way to optimize the methanol-air
mixture combustion process. A literature survey of structures of currently used pre-chambers …

The pre-chamber combustion concept (PCC) concept shows promises for lean combustion
to achieve improved combustion stability and engine efficiency. The KAUST narrow-throat …

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 …

Providing high ignition energies to low reactivity (hard-to-ignite) fuels in premixed
combustion modes is a challenging task. This is especially true if diluted combustion and …

Pre-chamber spark ignition (PCSI) combustion is an emerging lean-burn combustion mode
capable of extending the lean operation limit of an engine. The favorable characteristic of …

Lean combustion is a promising strategy to increase thermal efficiency in an internal
combustion engine, by exploiting a favorable specific heat ratio of the fresh mixture while …

A parametric direct numerical simulation study was conducted to investigate the effects of
the initial flow field (quiescent or turbulent), nozzle inlet sharpness and width, main chamber …

Turbulent jet ignition (TJI) has the advantages of improving burning rates and expanding
lean burn limitations of gasoline engines. Based on a single cylinder engine, combustion …

Diesel engines use diffusion-controlled combustion of a high-reactivity fuel and offer high
efficiencies because they combine lean combustion with a high compression ratio. For low …

In this work, numerical simulations of an automotive-sized scavenged pre-chamber mounted
in an opticallyaccessible rapid compression-expansion machine (RCEM) have been carried …
