4-3). That bit of technology went away when automakers switched to direct-injection, but Maserati is looking at reviving it in the gasoline engine-powered 2022 MC20. But it isn’t the only automaker thinking about utilizing hyper-efficient prechamber ignition technology in future products. Pre-chamber ignition systems are not a new idea, and have been used in industrial diesel and natural gas engine applications for decades. However, the past five years has seen their adoption in four-stroke gasoline engines used in motorsport series where fuel-flow restrictions place a premium on thermal efficiency, notably Formula 1 and in the LMP1Read More The proposed technology is a system which utilizes an active prechamber in the shape of an annulus and a high-pressure direct fuel injector. The active prechamber and the high-pressure direct injector use the same liquid fuel, which could be any fuel that has relatively high volatility and high resistance to autoignition (i.e., high-octane number). Although Honda has used the pre-chamber ignition technology on Honda cars in the 1970s, the technology is now standard on most Formula 1 engines.

We've recently learned the 2022 … Prechamber ignition is identified as a promising method to improve lean limit and has the potential to reduce end gas auto-ignition.

Research in the field of prechamber combustion has been extensive in the past Pre-chamber ignition has been investigated since the early 1900s as a technology which promotes rapid ignition of lean fuel mixtures. MAHLE Jet Ignition’s design uses a very small auxiliary pre-chamber (less than 3% of the main chamber clearance volume). Prechamber or divided chamber spark-ignition engines are modifications of conventional engines in which a rich air-fuel mixture is generated in the spark plug region of the prechamber while a lean mixture, or even pure air, is inducted into the main chamber. Under high load, high boost running, the pre-chamber ignition system is used, preventing detonation and enabling high boost levels, while at low loads the traditional plug ignition comes into play.

The five individual areas of focus in the DOE-funded project are: engine-knock mitigation, dilute (lean) combustion, thermal management, friction Prechamber ignition technology improves efficiency by fostering faster combustion. 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. While pre-chamber ignition technology has been in use for several decades in large-bore marine and power generation platforms, it is now finding its way into smaller-scale applications via medium- and heavy-duty trucks, Biruduganti said. April 2, 2021 Ford is investigating the possibility of producing efficient diesel engines with prechamber ignition technology, the same system used in Maserati’s innovative twin-turbocharged Without getting too technical, the prechamber creates a more efficient burn of the air-fuel mixture in the combustion chamber. From a performance standpoint, this leads to faster combustion which Diesel engines used to initiate combustion in a prechamber that housed the glow-plug for cold-starts, but fancy high-pressure direct-injection pretty much retired the prechamber. 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.

Upon ignition in the prechamber, the combustion gases expand into the main chamber through a small orifice and ignite the lean charge in the main combustion chamber. The three-valve concept was tested in a modified 400 CID V-8 engine as shown in Figure 4-2 (Ref.
