Abstract

An ignition apparatus for an internal combustion engine comprises an intake path supplying a mixture of air and fuel into the combustion chamber of the engine, a particle supplying unit having an ejection port opening into the combustion chamber for supplying minute particles of a material which is not the fuel and has a high light absorption factor, and a light source radiating a laser beam through a light focusing unit toward a suitably selected position in the internal space of the combustion chamber, so that the laser beam can strike the minute particles of high light absorption factor supplied from the particle supplying unit thereby producing a torch for igniting the air-fuel mixture.
