An improved ignitor and ignition method for igniting a wide variety of fuels that may be used to power various types of engines, or for use with other applications requiring the efficient combustion of fuel. The fuel to be burned is mixed with air to form a relatively lean first fuel/air mixture. This first fuel/air mixture is then injected into the primary combustion chamber, such as the combustion zone of a cylinder of an internal combustion engine, or similar combustion chamber of other types of fuel-burning apparatus. The first fuel/air mixture is ignited with a stream of hot ionized gas that is jetted into the primary combustion chamber from a precombustion or plasma-generating chamber. The plasma-generating chamber is in close proximity to the primary combustion chamber, with a plasma guide or discharge tunnel connecting the two. A fuel line connects a source of pressurized fuel to the plasma-generating chamber. Interposed in this fuel line are a backflow restrictor and a fuel vaporizor, thereby ensuring that only vaporized fuel passes into (and not out of) the plasma-generating chamber through the fuel line.

A plasma ignitor for use with a primary combustion chamber having means for introducing a fuel/air mixture therein, said plasma ignitor comprising: a plasma-generating chamber; means for introducing a fuel into said plasma-generating chamber comprising: a source of pressurized fuel, a fuel line connecting said source of pressurized fuel with said plasma-generating chamber, and backflow restriction means interposed in said fuel line for opposing reverse flow action of said fuel therethrough and allowing said fuel to seep forwardly therethrough at a rate being generally proportional to the pressure imposed on said fuel; gas ionization means in contact with said plasma-generating chamber for converting said fuel within said plasma-generating chamber into a hot ionized gas at controlled time intervals; and discharge nozzle means for jetting said hot ionized gas into the primary combustion chamber, said hot ionized gas serving to ignite and efficiently burn said fuel/air mixture contained in said primary combustion chamber.
