Measurement of the air-to-fuel ratio inside a passive pre-chamber of a fired spark-ignition engine [PDF]

open access: yesAutomotive and Engine Technology, 2020
AbstractThis paper investigates the local air-to-fuel ratio measurement within the pre-chamber of a spark-ignition engine by determining the absorption of light from hydrocarbons using an infrared sensor. The measurement was performed during fired and motored engine operation points and compared to the more common exhaust lambda measurements.

Advantages of hydrogen addition in a passive pre‐chamber ignited SI engine for passenger car applications

open access: yesInternational Journal of Energy Research, 2021
[EN] Hydrogen is one of the most promising alternative fuels for the transportation industry. The use of hydrogen to enable lean burn in internal combustion engines is an attractive solution for reducing CO2 emissions from two points of views: the substitution of carbon-based fuels and the increased thermal efficiency due to lean operation.
