Abstract From the Canadian patent

Internal combustion engines decrease environmental pollution and increase energy efficiency by using a fluid fuel reforming ceramic catalyst comprising a core 2 of a complex oxide ceramic of transition metals, an intermediate layer 3 of an alumina-based silicate ceramic covering the core 2 and an outer layer 4 of a ceramic containing noble metals. Transporting and power-generating means using such internal combustion engines increase the combustion efficiency and decrease the noxious substances in exhaust gases by converting the incombustible and environment polluting substances contained in fluid fuels to combustible substances and activating the oxygen in the air contained in fluid fuels.

Why it's free to use

  • Filed March 4, 1997 and granted May 29, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 4, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 4, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
