Abstract

A catalytic prereaction timing ignition method and igniter unit for timed ignition of a fuel-air mixture in internal combustion engines providing an ignition chamber open into the combustion chamber of the engine, there being a catalytic igniter positioned in the ignition chamber to intercept a pressure front of stratified fuel-air mixture penetrating a prechamber timing zone of the ignition chamber and controlled by the spring rate of burnt gasses captured in a buffer zone of the ignition chamber during the compression cycle and ignited by the pressure front touching the igniter to effect the power stroke of the engine.
