Reducing the pre-chamber nozzle diameter increases pre-chamber jet velocity and hence promotes turbulent mixing in the main chamber, but the lower limit is governed by discharge coefficient and pre-chamber jet momentum. Based on studies so far, a pre-chamber volume fraction of 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. High-compression racing engines often suffer from pre-ignition. Pre-ignition happens when the air and fuel mixture in the cylinder of an engine is ignited before the spark plug fires. This is typically caused from a hot spot in the compression chamber or by a spark plug that is too hot. It has previously been shown by the authors that the pre-chamber ignition technique operating with fuel-rich pre-chamber combustion strategy is a very effective means of extending the lean limit of combustion with excess air in heavy duty natural gas engines in order to improve indicated efficiency and reduce emissions.
Ford’s proposed pre-chamber ignition provides this by way of tiny holes that literally shoot fire jets into the main combustion chamber, which also allows later firing of the spark, closer to when the piston … 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). 2019-06-01 2020-10-06 Honda has filed a patent for a pre-chamber ignition system on motorcycles. This technology has been around for decades, but could now be used in production motorcycles for the first time. The system features a small chamber in front of the main combustion chamber. In this chamber, the spark plug ignites the air-fuel mixture. And what better way than to have pre-chamber ignition a key.

Recently Maserati too applied the same F1 tech in there car MC20 to improve the combustion efficiency. Well, Prechamber technology is nothing new, and Honda used this technology in the 1970s. So how does the pre-chamber ignition work?
A pre-chamber ignition device without additional fuelling reduces cyclic variations of combustion event but is not capable of considerably extending the lean limit.

An ignition system (10) for an internal combustion engine (12) having at least one combustion chamber (22) where the ignition system (10) includes a housing (42), an ignition device (86), an injector (90), and a pre-chamber (50) having a nozzle (78) disposed spaced from the proximal portion (76) of the pre-chamber (50). Methods and systems for a prechamber ignition system are provided. In one example, a prechamber ignition system may include an antechamber extending into a combustion chamber, a piston protrusion shaped to fit through a lower opening of the prechamber, and a plurality of openings formed by a sidewall of the prechamber.

In this free webinar, MAHLE Powertrain’s Adrian Cooper and Dr Mike Bassett present the latest test results, which demonstrate the capability of the passive MJI system to enable whole map λ=1 operation
Scavenged pre-chamber ignition systems aim to address this challenge by creating favourable ignition conditions close to stoichiometry in the spark region. The main lean charge ignition is then delivered by flame jets propagating through the nozzles connec-ting the pre-chamber to the cylinder. For the uninitiated, the pre-chamber ignition technology comes in two forms – Active pre-chamber and passive pre-chamber. According to the leaked images, Honda’s pre-chamber technology appears to be the Active type, but Honda has incorporated a rotating pre-chamber and feature dual-stage injectors.

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.
This technology has been around for decades, but could now be used in production motorcycles for the first time. The system features a small chamber in front of the main combustion chamber. In this chamber, the spark plug ignites the air-fuel mixture. The pre-chamber ignition concept is an attractive strategy to enable the operation of spark-ignition engines in lean or diluted conditions keeping a suitable combustion process. In pre-chamber ignition systems, an auxiliary charge is ignited inside a smaller pre-chamber linked to the main chamber by multiple ducts. Combustion inside the pre-chamber creates a pressure increase due to thermal expansion. The pressure di erence between the two chambers creates a ow out of the pre-chamber, which forces the 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.
Pre-chamber ignition is exactly what it sounds like, a small chamber that is usually partitioned from the main combustion chamber. There are two types of systems in use, active and passive pre-chamber ignition systems. Active pre-chamber systems (as with the Honda patent) contain a spark plug and fuel injector.
