Abstract (en)

A photocatalytic ignition system is provided that basically comprises an ignition chamber, a photocatalyst and a light source. The ignition chamber is configured to receive an air fuel mixture. The photocatalyst is arranged in the ignition chamber to contact an air fuel mixture. The light source is arranged to shine light on the photocatalyst. The photocatalyst includes a photocatalytic material having an oxygen absorbing and a desorbing function. The photocatalytic ignition system is capable of igniting a lean air fuel mixture with a greatly reduced amount of light energy.
