Abstract: A method for reforming fuel for an engine is disclosed. The method comprising heating, in a non-catalytic combustor, a mixture of fuel and air at a temperature in a range from 550K to 950K, to partially oxidize the fuel to generate one or more free radicals. The one or more free radicals constitute reformed fuel. Further, the reformed fuel is supplied to the engine.

Abstract: An internal combustion engine is provided. The internal combustion engine includes an engine block having at least one cylinder. The internal combustion engine includes a cylinder head engaged with the engine block. The internal combustion engine includes a pre-chamber assembly associated with the cylinder head. The pre-chamber assembly includes a pre-chamber in fluid communication with a main combustion chamber. The pre-chamber assembly includes a fuel supply unit in fluid communication with the pre-chamber to selectively supply fuel to the pre-chamber. The pre-chamber assembly includes an auxiliary unit configured to produce oxygen and hydrogen. The auxiliary unit is in fluid communication with the pre-chamber to supply oxygen to the pre-chamber and in fluid communication with the main combustion chamber to supply hydrogen to the main combustion chamber. The pre-chamber assembly includes an ignition unit associated with the pre-chamber to selectively ignite a mixture of fuel and oxygen in the pre-chamber.
