15 Dec 2020 Prechamber Combustion for Future Honda Superbikes? · Honda's new patent shows a CBR1000RR fitted with a prechamber combustion system.

the prechamber is used. Ignition is triggered inside the prechamber by means of a resistive heating of the prechamber walls. As a numerical study using detailed chemistry proved difficulties in convergence and was very intensive in calculation time (Wunsch, Heyne, Vos & Favrat, 2007), a simplified combustion model implemented

In some instances, electrodes 325 of a spark plug 124 in the prechamber 310 ignite the air-fuel mixture in the prechamber 310 to initiate ignition. Although the ignition in the prechamber and the torch flame injection from the prechamber were confirmed, the ignition in the main chamber did not occur with the CH4/air mixture at the equivalence ratio Φ = 0.7, the initial pressure P0 = 0.1 MPa, and the prechamber nozzle diameter d = 1.5 mm. Based on this result, the ignition and combustion 2020-01-02 US20060219210A1 US11/093,939 US9393905A US2006219210A1 US 20060219210 A1 US20060219210 A1 US 20060219210A1 US 9393905 A US9393905 A US 9393905A US 2006219210 A1 US2006219210 A1 US 2006219210A1 Authority US United States Prior art keywords prechamber combustion chamber engine fuel main combustion Prior art date 2005-03-30 Legal status (The legal status is an assumption … 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. 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.

MAHLE Jet Ignition’s design uses a very small auxiliary pre-chamber (less than 3% of the main chamber clearance volume). ( Earlier post .) A technology widely used in these engines is the prechamber ignition system, in which the external ignition source is located in a separate small volume, connected to the main chamber via small orifices [1, 2]. This setup allows for design of favorable condi-tions near the ignition source, in particular controlled flow properties (absence of large It uses a passive Prechamber + a later The new Maserati Nettuno is a petrol (gasoline) Engine twin Turbo 3.0-litre V6 that will power the MC20 super Sportscar.

The hot jet can be generated by burning a small quantity of fuel/air mixture in a prechamber. The high pressure in the prechamber resulting from heat release will force the products of combustion at high velocities into the main chamber generating a turbulent jet which then ignites the mixture in the main chamber.
