Thus far, research indicates that when combined with various technologies including a split cooling system, an electrified turbo boost system, and continuously variable valve timing, the project looks to be on track to meet its 23 percent boost in efficiency. From this review can be observed that the pre-chamber ignition system is an important way to increase thermal efficiency, reduce fuel consumption and emissions in spark ignition engines. Previous article in issue 2021-03-25 · The prechamber concept helps with those first two by fostering much faster combustion. The faster the mixture burns, the less need to fire the spark plug early (while the piston is still on its 2018-01-05 · Though, prechamber ignition systems has demonstrated a reduction in combustion duration and an extension of the lean limit , , and, unlike the other systems, NO x emissions in this case are drastically reduced, due to lower peaks of temperature, reaching levels close to zero (<10 ppm) . Bowl Prechamber Ignition, abbreviated BPI, is a combustion process designed for Otto cycle engines running on an air-fuel mixture leaner than stochiometric (>). Its distinguishing feature is a special type of spark plug , capable of reliably igniting very lean air-fuel mixtures.

We’ve recently learned the 2022 Maserati MC20 Nettuno V-6 engine is reviving it—in gasoline engines—as a way to speed the burn rate and extract more work and performance out of the air-fuel mixture. In this paper, a literature review has been made about prechamber ignition systems as lean combustion technology, focusing in the several investigations regarding combustion and emissions characteristics and presenting the key advantages and challenges in prechamber ignition technology application. Pre-chamber technology per se is not new; it has been used for decades in diesel engines and Honda introduced it in the early 1970s for the first-generation Civic’s 4-cyl. spark-ignition gasoline engine, dubbing it CVCC (Compound Vortex Controlled Combustion). Concepts about homogeneous and stratified prechamber ignition systems are presented. • Summary is provided for the main works concerning the prechamber ignition systems.
