Abstract
An engine includes a main combustion chamber; an intake duct configured to provide a lean fuel-oxidizer mixture to the main combustion chamber; a pre-chamber in fluid communication with the main combustion chamber, the pre-chamber including an ignition energy source operatively coupled to the pre-chamber, and a heating element in thermal communication with the pre-chamber; and a controller operatively coupled to the ignition energy source and the heating element. The controller is configured to initiate combustion of the lean fuel-oxidizer mixture in the main combustion chamber by activating the ignition energy source, and heat fuel and oxidizer in the pre-chamber via the heating element to a temperature sufficient to produce hydrogen peroxide (HO) in the pre-chamber.
