An improved ignition system is herein proposed for use specifically in combination with an automotive engine having an exhaust recirculation system which is adapted to have the exhaust gases recirculated from the engine exhaust system to the engine during predetermined conditions in which toxic nitrogen oxides are produced in the engine in relatively great quantities. the ignition system uses an additional high-tension current generator connected between an ignition power source and an ignition distributor in parallel with a usual high-tension current generator. An electrical circuit arrangement including these two high-tension generators is adapted to fire the air-fuel mixture in the engine with usual energy when the exhaust recirculation system is inoperative and with intensified energy in response to a condition in which the recirculation system is operative. |
