1. A method of positive curve ignition timing in internal combustion engines having a compression cycle and ignition of a combustible fuel-air mixture in a combustion chamber followed by a power cycle, and including;

  • the first step of providing a closed pre-chamber in open communication with the combustion chamber for penetration therein of a pressure front of a mass of combustible fuel-air mixture,the second step of positioning an electrically powered hot wire anemometer-heater element having a determined mass and applying voltage and current thereto and at a depth of pressure front penetration of said combustible fuel-air mixture into the pre-chamber at a determined compression of said combustible fuel-air mixture, electrical resistance through the hot wire anemometer-heater element being sensed to increase electrical power to the hot wire anemometer-heater element for advanced ignition and to reduce power thereto for retarded ignition, thereby adjusting a positive curve timing slope,the third step of transferring the mass of combustible fuel-air mixture from the combustion chamber and into the pre-chamber for cooling contact with and over the said hot wire anemometer-heater element during the compression cycle and for the transfer of heat between the mass of the combustible fuel-air mixture and the mass of the hot wire anemometer-heater element.the fourth step of capturing a volume of previously burnt non combustible gasses in the pre-chamber for occlusion of the hot wire anemometer-heater element and for depression as a spring,and the fifth step of depressing said captured previously burnt and combustible gases with the penetrating pressure front of combustible fuel-air mixture for said contact over the hot wire anemometer-heater element for ignition thereby and transfer of burning plasma into the combustion chamber for continued burning of the combustible fuel-air mixture therein to effect the power cycle and leaving burnt non combustible gases in the pre chamber.
