Claim Text:
1. A method for stabilizing combustion in a lean-burn engine, comprising: providing the lean-burn engine, the lean-burn engine including a combustion chamber and a pre-chamber in fluid communication with the combustion chamber, the pre-chamber having a spark igniter and a heating element contained in the pre-chamber; providing a mixture of fuel and air to the pre-chamber; using the heating element to heat the pre-chamber to a temperature sufficient to produce hydrogen peroxide (H providing a lean fuel/air mixture to the combustion chamber; delivering the H igniting the lean fuel/air mixture in the combustion chamber with the spark igniter to initiate combustion of the lean fuel/air mixture, the ignition producing hydroxyl radicals (OH·) from the H stabilizing the combustion in the combustion chamber with the OH· radicals.
